There are few things worse than your furnace running but blowing lukewarm or cold air during an Ontario winter. Before you panic and call for emergency service, there are several common causes you can check yourself — and some quick fixes that might solve the problem in minutes.

1. Check Your Thermostat First

It sounds obvious, but thermostat issues are the number one cause of "furnace not heating" calls in the GTA. Make sure the thermostat is set to "Heat" mode (not "Cool" or "Fan Only") and the temperature is set at least 3°C above the current room temperature. If the fan is set to "On" instead of "Auto," the blower will run constantly — even when the furnace isn't heating — pushing cold air through your vents.

2. Replace a Dirty Air Filter

A clogged air filter restricts airflow through your furnace, which can cause the heat exchanger to overheat and trigger a safety shutoff. The furnace continues to blow air, but the burner has shut down — so you get cold air. Check your filter every 1-2 months during winter and replace it if it's visibly dirty. A standard 1-inch filter should be changed monthly; thicker pleated filters last 3-6 months.

3. Check the Pilot Light or Igniter

If you have an older furnace with a standing pilot light, make sure it's lit. If it won't stay lit, the thermocouple may need replacement. Newer furnaces use electronic igniters — if you hear clicking but no flame, the igniter may have failed. This is a common repair that typically costs $150-$300 installed.

4. Inspect Your Vents and Ductwork

Walk through your home and make sure all supply vents are open and unobstructed. Closed or blocked vents reduce airflow and can cause the system to overheat. Check for disconnected or damaged ductwork in your basement or attic — leaking ducts can lose up to 30% of heated air before it reaches your rooms.

5. Check the Condensate Drain (High-Efficiency Furnaces)

If you have a high-efficiency furnace (90%+ AFUE), a clogged condensate drain can cause the furnace to shut down as a safety measure. Check the drain line for blockages and clear any debris. In freezing weather, the condensate line can freeze — particularly if it runs through an unheated space.

When to Call a Professional

If you've checked all the above and your furnace still isn't blowing hot air, it's time to call a licensed HVAC technician. The issue could be a faulty gas valve, a cracked heat exchanger, a bad blower motor, or a control board failure — all of which require professional diagnosis and repair.

Wondering how much a furnace repair will cost you in the GTA? Prices vary depending on the part, the age of your furnace, and how quickly you need service. Here's a realistic breakdown of what Toronto homeowners can expect to pay in 2025.

Common Furnace Repair Costs

• Igniter replacement: $150–$300
• Thermocouple replacement: $100–$200
• Flame sensor cleaning/replacement: $75–$250
• Blower motor replacement: $400–$800
• Gas valve replacement: $350–$650
• Control board replacement: $400–$700
• Heat exchanger replacement: $1,000–$2,500
• Inducer motor replacement: $400–$700
• Thermostat replacement: $150–$400

What Affects the Price?

Part availability: Common parts for popular furnace brands (Carrier, Lennox, Trane, Goodman) are readily available and more affordable. Older or discontinued models may require special-order parts that cost more.

Emergency vs. scheduled service: After-hours, weekend, or holiday calls typically carry a premium of $100–$200. If your furnace breaks on a mild day, scheduling during regular hours saves money.

Furnace age: Furnaces over 15 years old may need parts that are harder to source. In some cases, the cost of repairing an old furnace makes replacement the smarter financial decision.

Diagnostic Fees

Most HVAC companies in Toronto charge a diagnostic fee of $80–$150 to send a technician to your home, inspect the furnace, and identify the problem. At Fateh HVAC, we waive the diagnostic fee when you proceed with the repair.

Is It Worth Repairing?

A good rule of thumb: if the repair cost is more than 50% of the price of a new furnace, and your current furnace is over 15 years old, replacement is usually the better investment. A new high-efficiency furnace also comes with manufacturer warranties and energy savings.

If your furnace fires up, runs for a few minutes, then shuts off before your home reaches the set temperature — only to turn on again shortly after — you're dealing with short cycling. It's one of the most common furnace problems GTA homeowners face, and it can significantly increase your energy bills while putting extra wear on your system.

What Causes Short Cycling?

1. Dirty Air Filter (Most Common)

A clogged filter restricts airflow, causing the heat exchanger to overheat. The furnace's high-limit safety switch trips and shuts the burner off. Once it cools, the furnace restarts — and the cycle repeats. Fix: Replace the filter. This alone solves the problem in about 40% of short cycling cases.

2. Oversized Furnace

If your furnace is too powerful for your home's square footage, it heats the space too quickly. The thermostat reaches its set point and shuts the furnace off before a full heating cycle completes. This leads to frequent on-off cycling, uneven temperatures, and excessive wear. This is a design problem that requires professional assessment.

3. Blocked Vents or Registers

Closed or obstructed supply vents reduce airflow through the system, mimicking the effects of a dirty filter. Make sure all vents are open and clear of furniture, rugs, or curtains.

4. Faulty Thermostat

A malfunctioning thermostat can send incorrect signals to the furnace, causing it to cycle erratically. If your thermostat is old or located near a heat source (direct sunlight, a lamp, a vent), it may be reading the temperature inaccurately. Consider upgrading to a modern programmable or smart thermostat.

5. Flame Sensor Issues

The flame sensor confirms that the burner has ignited. If it's dirty or corroded, it can't detect the flame and tells the furnace to shut off as a safety measure. Cleaning or replacing the flame sensor is a straightforward repair.

Why Short Cycling Is a Problem

Short cycling wastes energy because the furnace uses the most fuel during startup. Frequent starts also put extra stress on the blower motor, igniter, and other components — shortening your furnace's lifespan. If left unresolved, it can lead to expensive repairs or premature furnace replacement.

A loud bang, boom, or pop from your furnace is unsettling — and in some cases, it's a sign of a serious problem. The type of noise and when it occurs can help you (and your technician) narrow down the cause.

Types of Furnace Noises and What They Mean

Loud Bang or Boom at Startup

This is the most common complaint and usually indicates delayed ignition. Gas builds up in the combustion chamber before the igniter lights it, causing a small explosion. This can crack the heat exchanger over time. Common causes include a dirty burner, a weak igniter, or low gas pressure. This should be addressed promptly.

Rattling or Vibrating

Usually caused by loose screws, ductwork, or panels. Check that the access panels are seated tightly. If the rattling comes from inside the unit, it could be a loose blower wheel or motor mount.

Squealing or Screeching

A high-pitched squeal typically points to a worn blower belt or failing blower motor bearing. The belt may need adjustment or replacement; bearings may need lubrication or indicate the motor is nearing end of life.

Clicking Repeatedly

Repeated clicking without the furnace igniting usually indicates a problem with the igniter, flame sensor, or control board. The furnace is trying to start but can't complete the ignition sequence.

Booming or Thumping When Running

This can indicate dirty burners causing uneven ignition, or expanding and contracting ductwork. Dirty burners should be cleaned professionally. Ductwork noise is usually harmless but can be reduced with duct insulation or flexible connectors.

When to Call for Service

If you hear a loud bang at startup, smell gas, or hear repeated clicking without ignition, turn off the furnace and call a licensed HVAC technician immediately. Delayed ignition can damage the heat exchanger, and a cracked heat exchanger is a serious safety hazard.

When your gas furnace won't ignite, the house gets cold fast — especially during a GTA winter. Before calling for service, there are a few things you can check that might solve the problem without a repair visit.

Step 1: Check the Thermostat

Make sure the thermostat is set to "Heat" and the temperature is set above the current room temperature. Try replacing the batteries if it's a battery-powered thermostat. If the display is blank, check the furnace's power switch and circuit breaker.

Step 2: Check the Gas Supply

Make sure the gas shutoff valve near the furnace is fully open (the handle should be parallel to the pipe). Check that other gas appliances in your home (stove, water heater) are working — if not, you may have a gas supply issue. If you smell gas, leave your home immediately and call your gas company.

Step 3: Check the Pilot Light (Older Furnaces)

If you have an older furnace with a standing pilot light, look for the pilot through the sight glass or by removing the access panel. If it's out, follow the relighting instructions on the furnace label. If it won't stay lit after relighting, the thermocouple is likely faulty — a common and inexpensive repair.

Step 4: Reset the Furnace

Many modern furnaces have a reset button (usually red) on the blower motor housing. Turn off the furnace, wait 30 seconds, then turn it back on. If the furnace has a diagnostic LED, count the flashes and check the error code chart on the inside of the access panel — this can tell you exactly what's wrong.

Step 5: Check for a Dirty Flame Sensor

The flame sensor is a small metal rod that sits in front of the burner flame. If it's coated in residue, it can't detect the flame and will shut off the gas as a safety measure. You can clean it gently with fine steel wool or emery cloth — but be careful not to damage it.

Common Ignition-Related Repairs

• Electronic igniter replacement: $150–$300
• Thermocouple replacement: $100–$200
• Flame sensor cleaning/replacement: $75–$250
• Gas valve replacement: $350–$650
• Control board replacement: $400–$700

One of the toughest decisions a homeowner faces is whether to invest in repairing an aging furnace or bite the bullet and replace it. Here's how to make the right call based on your furnace's age, condition, and repair history.

The 50% Rule

If the cost of the repair is more than 50% of the cost of a new furnace, replacement is almost always the better financial choice — especially if the furnace is over 15 years old. A new furnace comes with a manufacturer warranty (typically 10 years on the heat exchanger, 5 years on parts) and improved energy efficiency that will lower your monthly bills.

Age Matters

Under 10 years old: Repair is usually worthwhile. The furnace has plenty of life left, and parts are readily available.

10-15 years old: Depends on the repair. Minor fixes (igniter, flame sensor, thermostat) are worth it. Major repairs (blower motor, gas valve, control board) warrant a cost-benefit analysis.

15-20+ years old: Start planning for replacement. Even if a repair fixes the current issue, other components are likely to fail soon. Energy efficiency has improved dramatically — a new 96% AFUE furnace uses significantly less gas than an older 80% model.

Warning Signs It's Time to Replace

• Rising energy bills: If your heating costs keep climbing despite maintenance, the furnace is losing efficiency.
• Frequent repairs: If you've called for service 2+ times in the last two years, you're approaching a tipping point.
• Uneven heating: Cold spots in your home can indicate a furnace that's no longer performing properly.
• Yellow burner flame: A healthy gas flame should be blue. Yellow or flickering flames can indicate incomplete combustion and potential carbon monoxide production.
• Strange noises: Increasing banging, squealing, or rattling signals worn components.
• Dust and humidity issues: An aging furnace can struggle to filter air and maintain proper humidity.

The Benefit of a New Furnace

A new high-efficiency furnace (96-98% AFUE) can save you 20-30% on heating costs compared to an older 80% model. Combined with Enbridge rebates and potential government incentives, the payback period can be surprisingly short. You also get quieter operation, more even heating, and the peace of mind of a full warranty.

Ontario winters are unforgiving, and your furnace is the only thing standing between your family and sub-zero temperatures. Regular maintenance keeps your furnace running safely, efficiently, and reliably — and it can prevent expensive mid-winter breakdowns. Here's what every GTA homeowner should do.

Monthly Tasks (DIY)

• Check and replace the air filter. During heavy-use months (November-March), check your filter monthly. A dirty filter reduces efficiency, increases energy bills, and can cause the furnace to overheat. Standard 1-inch filters should be replaced monthly; pleated 4-inch filters last 3-6 months.
• Inspect vents and registers. Walk through your home and make sure all supply and return vents are open and unblocked by furniture, curtains, or rugs.
• Check the thermostat. Make sure it's reading the correct temperature and responding properly. Replace batteries annually if applicable.

Annual Professional Tune-Up

A professional furnace tune-up should be done every fall before heating season. During a typical tune-up, a licensed technician will:

• Clean and inspect the burners
• Test the flame sensor and igniter
• Check the heat exchanger for cracks or corrosion
• Inspect the blower motor and belt
• Test all safety controls
• Measure gas pressure and check for leaks
• Inspect the flue/venting for blockages
• Lubricate moving parts
• Check carbon monoxide levels

A tune-up typically costs $100-$180 and is the single best investment you can make in your furnace's longevity and your family's safety.

Safety Tips

Install carbon monoxide detectors. Ontario law requires CO detectors outside all sleeping areas in homes with fuel-burning appliances. Test them monthly and replace batteries yearly. A cracked heat exchanger can leak CO into your home without any visible signs.

Keep the area around the furnace clear. Don't store flammable materials, chemicals, or boxes near your furnace. Leave at least 3 feet of clearance around the unit.

Know where the gas shutoff valve is. Every household member should know how to shut off the gas supply in an emergency.

Replacing your furnace is a significant investment, but understanding the costs upfront helps you budget and avoid surprises. Here's a complete breakdown of new furnace costs in Ontario for 2025, including installation, ductwork, and available rebates.

Furnace Prices by Size and Type

• 40,000-60,000 BTU (small home/apartment): $2,500-$4,000 installed
• 60,000-80,000 BTU (average home): $3,500-$5,500 installed
• 80,000-100,000 BTU (larger home): $4,500-$7,000 installed
• 100,000+ BTU (large home/2-stage): $5,500-$9,000+ installed

These prices include the furnace, standard installation labour, and basic ductwork connections. Two-stage and variable-speed furnaces cost more upfront but provide better comfort and lower operating costs.

What Affects the Total Cost?

Efficiency rating (AFUE): An 80% AFUE furnace costs less upfront but wastes 20 cents of every dollar on exhaust heat. A 96% AFUE furnace costs more but pays you back through lower monthly bills. In Ontario's cold climate, high-efficiency models pay for themselves faster.

Ductwork modifications: If your existing ductwork is in good condition, you'll save money. If it needs repairs, resizing, or replacement, expect to add $1,000-$3,000+ to the project.

Permits and inspections: A building permit for furnace replacement in the GTA typically costs $150-$300. Your contractor should handle this.

Extras: New thermostat ($150-$400), humidifier ($400-$800), air filtration system ($300-$1,000), and ductwork sealing ($300-$800) are common add-ons.

Available Rebates and Incentives

Ontario homeowners can take advantage of several rebate programs when installing a high-efficiency furnace:

• Enbridge Gas rebates: Periodically offered for qualifying high-efficiency furnace installations
• Canada Greener Homes Grant: Federal program offering up to $5,000 for energy-efficient home upgrades (check current availability)
• Manufacturer rebates: Seasonal promotions from brands like Carrier, Lennox, and Trane

When your air conditioner is running but your home isn't getting cool, the problem can range from a quick DIY fix to a serious mechanical issue. Here are the seven most common causes — and what you can do about each one.

1. Dirty Air Filter

A clogged filter restricts airflow over the evaporator coil, reducing cooling capacity and potentially causing the coil to freeze. Replace your filter every 1-3 months during cooling season.

2. Dirty or Blocked Outdoor Unit

Your AC's condenser unit (the outdoor box) needs airflow to release heat. If it's covered in dirt, leaves, or debris, it can't do its job. Turn off the power and gently rinse the fins with a garden hose. Keep 2 feet of clearance around the unit.

3. Frozen Evaporator Coil

If the indoor coil is covered in ice, your AC can't absorb heat from your home. Common causes include low refrigerant, dirty filters, or a malfunctioning blower motor. Turn off the AC and let the coil thaw completely (this can take 2-4 hours) before investigating further.

4. Low Refrigerant

Refrigerant doesn't get "used up" — if levels are low, you have a leak. Signs include ice on the refrigerant lines, warm air from vents, hissing sounds near the indoor unit, and higher-than-normal energy bills. A licensed technician must locate the leak, repair it, and recharge the system.

5. Thermostat Issues

Make sure the thermostat is set to "Cool" and the temperature is below the current room temperature. Check that the fan is set to "Auto" (not "On," which runs the blower continuously without cooling). Consider replacing old thermostats with modern programmable or smart models.

6. Undersized AC Unit

If your AC has never adequately cooled your home, it may be undersized for your space. An HVAC professional can perform a load calculation to determine the correct size. Factors include square footage, insulation, windows, and ceiling height.

7. Ductwork Leaks

Leaking ducts can lose 20-30% of cooled air into unconditioned spaces like attics or crawlspaces. If some rooms are much warmer than others, ductwork problems are a likely culprit.

Your AC is on, the fan is running, but warm air is coming out of the vents. This frustrating problem has several common causes, many of which you can check yourself before calling for service.

Thermostat Settings

First, verify the thermostat is set to "Cool" and the fan is on "Auto." If the fan is set to "On," it will blow air even when the compressor isn't running — which means room-temperature air circulates through warm ductwork and comes out feeling warm. Switch the fan to "Auto" so it only runs during active cooling cycles.

Power to the Outdoor Unit

Check that your outdoor condenser unit is running. If you don't hear it humming, the unit may have lost power. Check the outdoor disconnect switch (usually a metal box near the unit), the circuit breaker in your electrical panel, and any fuses. A tripped breaker is common after power outages or electrical storms.

Refrigerant Leak

Low refrigerant is one of the most common causes of warm air. The system needs a specific amount of refrigerant to absorb heat from your home. When levels drop due to a leak, the evaporator coil can't absorb enough heat, and the air coming out feels lukewarm or warm. You might also notice ice forming on the refrigerant lines or indoor coil. A technician must find and repair the leak before recharging.

Compressor Problems

The compressor is the heart of your AC system — it pressurizes refrigerant and moves it through the system. If the compressor fails, the outdoor unit may still hum, but no cooling occurs. Compressor replacement is expensive ($1,500-$3,000+), and for older units, full system replacement is often more economical.

Dirty Coils

Both the indoor evaporator coil and outdoor condenser coil need to be clean to transfer heat effectively. Dirty coils reduce efficiency and can cause the system to blow warm air. Annual professional cleaning is recommended as part of regular AC maintenance.

Whether you're installing AC for the first time or replacing an aging unit, understanding the costs helps you budget and choose the right system. Here's what Toronto and GTA homeowners can expect to pay for air conditioning installation in 2025.

Central Air Conditioning

• 1.5-ton (up to 1,000 sq ft): $3,500–$5,000 installed
• 2-ton (1,000-1,500 sq ft): $4,000–$6,000 installed
• 2.5-ton (1,500-2,000 sq ft): $4,500–$7,000 installed
• 3-ton (2,000-2,500 sq ft): $5,000–$8,000 installed
• 4-ton (2,500-3,500 sq ft): $6,000–$9,500 installed

Central AC requires existing ductwork. If your home has a forced-air furnace, the ductwork is already in place, which significantly reduces installation cost.

Ductless Mini-Split Systems

• Single-zone (one room): $3,500–$5,500 installed
• Dual-zone (two rooms): $5,500–$8,000 installed
• Multi-zone (3-4 rooms): $8,000–$14,000+ installed

Ductless systems are ideal for homes without ductwork, additions, or situations where you want room-by-room temperature control.

What Affects the Price?

SEER2 rating: Higher-efficiency units (SEER2 16+) cost more upfront but save on monthly energy bills. In Ontario's climate, a SEER2 14-16 unit offers the best balance of cost and efficiency for most homes.

Electrical work: If your electrical panel needs an upgrade to accommodate the AC, budget an additional $500-$2,000.

Ductwork condition: Leaking or undersized ducts should be addressed during installation for optimal performance — budget $500-$2,000 for duct sealing or modifications.

Air conditioners don't last forever. If your AC is getting old and showing signs of trouble, replacing it before a complete breakdown can save you money, discomfort, and the stress of an emergency replacement during a heat wave.

Your AC Is Over 12-15 Years Old

The average lifespan of a central air conditioner in Ontario is 12-15 years. After this point, efficiency declines, breakdowns become more frequent, and replacement parts become harder (and more expensive) to source. If your unit is approaching this age, start budgeting for a replacement.

Frequent and Expensive Repairs

If you've needed AC repairs multiple times in the last 2-3 years, the costs add up quickly. Apply the 50% rule: if a repair costs more than half the price of a new unit, replacement is the smarter investment. A new AC also comes with a manufacturer warranty for peace of mind.

Rising Energy Bills

If your electricity bills keep climbing despite similar usage, your AC's efficiency has likely degraded. Modern AC units are significantly more efficient than models from even 10 years ago. Upgrading to a SEER2 16+ unit can reduce cooling costs by 20-40%.

Your AC Uses R-22 Refrigerant

R-22 (Freon) was phased out in Canada in 2020. If your AC still uses R-22, repairs involving refrigerant are extremely expensive because the supply is limited and dwindling. Replacing an R-22 system with a modern R-410A or R-32 system is both more economical and better for the environment.

Uneven Cooling

If some rooms are comfortable while others are hot, and you've ruled out ductwork issues, the AC may be losing capacity. An aging compressor or degraded coil can cause uneven cooling that no amount of repair will fully resolve.

Strange Noises or Smells

Grinding, squealing, or banging sounds indicate worn internal components. Musty smells suggest mold in the unit or ductwork. Burning smells are an electrical hazard and warrant immediate shutdown and service.

A well-maintained air conditioner runs more efficiently, lasts longer, and breaks down less often. These simple maintenance steps — most of which you can do yourself — will keep your AC performing at its best through the hottest GTA summers.

DIY Maintenance (Monthly)

• Replace or clean the air filter. A dirty filter is the number one cause of AC problems. Check it monthly during cooling season and replace it every 1-3 months.
• Clear debris around the outdoor unit. Keep 2 feet of clearance on all sides. Remove leaves, grass clippings, and any vegetation growing too close.
• Check the condensate drain. Find the drain line (usually a PVC pipe near the indoor unit) and make sure it's not clogged. Pour a cup of vinegar through it periodically to prevent algae buildup.
• Inspect the fins. If the aluminum fins on the outdoor unit are bent, straighten them gently with a fin comb. Bent fins restrict airflow and reduce efficiency.

Professional Maintenance (Annual)

A professional AC tune-up should be done every spring before cooling season. During a typical visit, the technician will:

• Clean the evaporator and condenser coils
• Check refrigerant levels and test for leaks
• Inspect electrical connections and capacitors
• Test the thermostat calibration
• Lubricate moving parts
• Check the blower motor and belt
• Inspect the condensate drain system
• Measure airflow and temperature differential

An AC tune-up typically costs $100-$150 and can prevent the most common mid-summer breakdowns.

Quick Tips to Reduce AC Costs

• Set the thermostat to 24-25°C when home, 27-28°C when away
• Use ceiling fans to circulate air (they make a room feel 2-3°C cooler)
• Close blinds and curtains on south and west-facing windows during the day
• Seal air leaks around windows and doors
• Avoid using the oven during peak afternoon heat

Choosing between central air conditioning and a ductless mini-split system is one of the biggest decisions GTA homeowners face when upgrading their cooling. Both have distinct advantages depending on your home, budget, and comfort needs.

Central Air Conditioning

How It Works

A central AC system uses a single outdoor compressor unit connected to an indoor evaporator coil (typically installed on top of your furnace). Cooled air is distributed through your home's ductwork to every room via supply vents.

Pros

• Lower equipment cost for whole-home cooling (if ductwork exists)
• Cools every room uniformly through existing ducts
• Hidden from view — only vents are visible
• Uses your furnace's blower and filtration system

Cons

• Requires ductwork — expensive to install if it doesn't exist
• Ducts can leak 20-30% of cooled air if not sealed properly
• One thermostat controls the whole house — no zone control
• Less efficient for cooling one or two rooms

Ductless Mini-Split

How It Works

A mini-split has an outdoor compressor connected to one or more indoor wall-mounted units via refrigerant lines. Each indoor unit has its own thermostat, providing independent temperature control for each room or zone.

Pros

• No ductwork required — ideal for older homes, additions, or converted spaces
• Room-by-room temperature control (zone cooling)
• Very energy efficient — no duct losses
• Most models also provide heating (heat pump function)
• Quiet operation

Cons

• Higher cost per zone for whole-home coverage
• Wall-mounted indoor units are visible
• Each indoor unit requires a refrigerant line run to the outdoor unit
• Filter maintenance required on each indoor unit

Cost Comparison

Central AC is more cost-effective for whole-home cooling in homes with existing ductwork: $4,000-$8,000 for a typical GTA home.

Ductless mini-splits are more cost-effective for targeted cooling, homes without ductwork, or when you want zone control: $3,500-$5,500 per zone.

When you turn on your AC and nothing happens — no fan, no cool air, no sound at all — the problem is usually electrical or thermostat-related. Here's a step-by-step troubleshooting guide before you call for service.

Step 1: Check the Thermostat

Make sure the thermostat is set to "Cool" and the temperature is set below the current room temperature. If the display is blank, the thermostat may have dead batteries or lost power. Replace the batteries and check if it comes back on.

Step 2: Check the Circuit Breaker

Your AC system has two breakers — one for the indoor unit (furnace/air handler) and one for the outdoor unit. Both need to be on. Check your electrical panel and look for any tripped breakers. Reset them by flipping fully to "Off" then back to "On." If the breaker trips again immediately, there's an electrical fault — don't keep resetting it; call a technician.

Step 3: Check the Emergency Shut-Off Switch

Many homes have an emergency shut-off switch near the furnace or air handler (it looks like a regular light switch). Make sure it's turned on. This switch gets accidentally flipped off more often than you'd think.

Step 4: Check the Outdoor Disconnect

There's an outdoor disconnect box near your AC condenser unit. This is usually a metal box with a pull-out switch or circuit breaker. Make sure it's fully engaged. Some disconnects have fuses that can blow — if you're comfortable checking, look for a blown fuse.

Step 5: Check the Condensate Drain Safety Switch

Many modern AC systems have a safety switch that shuts the system off if the condensate drain is clogged and water backs up. Check the drain pan under the indoor unit — if it's full of water, clear the drain line and empty the pan.

A washer that won't leave you with soaking wet clothes is frustrating — and a clear sign something's wrong. The spin cycle is what wrings water out of your laundry, and when it fails, the cause is usually one of these common issues.

1. Unbalanced Load

The most common reason a washer won't spin is an unbalanced load. Heavy items like towels, blankets, or jeans can bunch up on one side of the drum. The washer detects the imbalance and refuses to spin at full speed to prevent damage. Try redistributing the clothes evenly, or add a few smaller items to balance the load.

2. Lid Switch (Top-Loaders)

Top-loading washers have a lid switch that prevents spinning when the lid is open. If the switch is faulty, the washer thinks the lid is open and won't spin. You can test this by opening and closing the lid and listening for a click. If there's no click, the switch may need replacement ($100-$200 installed).

3. Drive Belt

If the drum doesn't spin at all (but the motor runs), the drive belt may be broken, worn, or slipped off the pulley. You can check this by spinning the drum by hand — if it spins freely with almost no resistance, the belt is likely the issue. Belt replacement costs $100-$250.

4. Drainage Issues

Most washers won't enter the spin cycle until the water has drained. If the drain pump is clogged or the drain hose is kinked, the water stays in the drum and the spin cycle never starts. Check the drain filter (usually behind a small panel at the bottom front of the machine) for coins, lint, or debris.

5. Motor Coupler or Clutch

In direct-drive washers, the motor coupler connects the motor to the transmission. If it breaks (common on older Whirlpool and Kenmore models), the motor runs but the drum doesn't spin. In belt-drive models, a worn clutch can cause similar symptoms. Both repairs cost $150-$300.

If your washing machine finishes the cycle but the tub is still full of water — or the cycle stops mid-way with an error code — you likely have a drainage problem. Here's how to troubleshoot and fix it.

Check the Drain Hose

The drain hose carries water from the washer to your standpipe or utility sink. Make sure it's not kinked, pinched, or pushed too far down the standpipe (it should be inserted no more than 6-8 inches). Also check that the standpipe itself isn't clogged.

Clean the Drain Filter

Most front-loading washers (and some top-loaders) have a drain filter — also called a coin trap — located behind a small panel at the bottom front of the machine. Place a towel and shallow pan underneath, then unscrew the filter cap slowly. Water will pour out, so be prepared. Remove any lint, coins, hairpins, or debris, then reattach the cap securely.

Inspect the Drain Pump

The drain pump pushes water out of the washer. If you hear the pump running but water isn't draining, the pump impeller may be blocked or broken. If you don't hear the pump at all when the drain cycle starts, the pump motor may have failed. A new drain pump costs $150-$350 installed.

Check for a Clogged Internal Hose

Sometimes the clog is inside the washer, between the tub and the pump. Lint, sock fragments, and small items can accumulate in this hose over time. This requires removing the washer's front or back panel to access — a job best left to a technician if you're not comfortable with appliance disassembly.

If your dryer tumbles but the clothes come out cold and damp, the heating system has failed. This is one of the most common dryer problems and has several possible causes — from simple fixes you can do yourself to repairs that require a professional.

Check the Basics First

Power supply: Electric dryers need 240V to heat. A partially tripped breaker can allow the drum to spin (120V) while cutting power to the heating element (240V). Check your electrical panel and make sure both dryer breakers are fully on.

Dryer settings: Make sure you haven't accidentally selected "Air Fluff" or "No Heat" mode. Try a timed dry cycle on high heat.

Clogged Vent (Most Common)

A clogged dryer vent is the number one cause of a dryer not heating properly. Lint builds up in the vent hose and duct over time, restricting airflow. The dryer's safety thermostat detects the heat buildup and shuts off the heating element. Signs of a clogged vent include clothes taking longer to dry, the dryer exterior feeling very hot, and excessive humidity in the laundry room. Clean your dryer vent at least once a year.

Heating Element (Electric Dryers)

The heating element is a coil that generates heat. Over time, it can burn out or break. A technician can test it with a multimeter and replace it if needed. Heating element replacement typically costs $150-$350 installed.

Gas Valve Solenoids (Gas Dryers)

Gas dryers have solenoids (coils) that open the gas valve to ignite the burner. If one fails, the burner won't light or will only light intermittently. Replacing gas valve solenoids costs $150-$300.

Thermal Fuse

The thermal fuse is a safety device that cuts power to the heating element if the dryer overheats. If it blows (usually due to a clogged vent), the dryer won't heat at all. Replacing the fuse costs $100-$200, but you must also fix the underlying cause (usually a clogged vent) or the new fuse will blow too.

If your dryer used to dry a full load in 45 minutes but now takes 90 minutes or more, something has changed — and ignoring it wastes energy, increases wear on your clothes, and can be a fire hazard. Here are the most common causes.

Clogged Dryer Vent (Most Likely)

When the vent is clogged with lint, hot moist air can't escape the dryer. The clothes sit in warm, damp air and take much longer to dry. This is the cause in the majority of "dryer not drying well" complaints. A professional vent cleaning ($100-$200) typically resolves the issue immediately.

DIY check: Disconnect the vent hose from the back of the dryer and run a load. If clothes dry much faster, the vent is the problem.

Lint Trap Issues

Clean the lint screen before every load. But also check for invisible buildup — dryer sheets and fabric softener leave a film on the screen that reduces airflow. Wash the lint screen with warm water and a soft brush every few months. Hold it under water — if water doesn't pass through easily, it needs cleaning.

Overloading

An overloaded dryer can't tumble clothes effectively, and hot air can't circulate between items. Dry smaller loads for faster, more efficient drying. Clothes should have room to tumble freely.

Worn Moisture Sensor

Modern dryers use moisture sensors (two metal strips inside the drum) to detect when clothes are dry. If the sensor is coated with residue from dryer sheets, it can't accurately detect moisture, and the dryer may shut off too early or run too long. Clean the sensor strips with rubbing alcohol and a cotton ball.

Weak Heating Element

A heating element that's partially worn may still produce some heat, but not enough to dry efficiently. The dryer feels warm but clothes take much longer. A technician can test the element's resistance and replace it if needed.

A warm fridge is a race against time — your food is spoiling and you need answers fast. Here's a systematic guide to diagnosing why your refrigerator isn't cooling and what you can do about it.

Step 1: Check the Basics

Make sure the fridge is plugged in and the outlet has power. Check the thermostat inside the fridge — it should be set between 2°C and 4°C (35-40°F). If someone accidentally turned it to the warmest setting, that's your problem. Also make sure the fridge isn't pushed too tight against the wall — it needs airflow behind and around it to dissipate heat.

Step 2: Check the Condenser Coils

The condenser coils (usually on the back or bottom of the fridge) release heat from the refrigerant. If they're covered in dust, pet hair, or grime, the fridge can't cool efficiently. Unplug the fridge and vacuum the coils thoroughly. Do this every 6-12 months as regular maintenance.

Step 3: Check the Evaporator Fan

Open the freezer door and listen — you should hear the evaporator fan running. If the freezer is cold but the fridge is warm, the fan that circulates cold air from the freezer to the fridge may have failed. The fan motor costs $100-$250 to replace.

Step 4: Check the Condenser Fan

The condenser fan (near the compressor at the back/bottom) blows air over the condenser coils. If it's not running, the fridge overheats. Check for obstructions and make sure the fan blade spins freely. A stuck or dead fan motor needs replacement ($150-$300).

Step 5: Check the Defrost System

If ice has built up on the evaporator coils (behind the back panel inside the freezer), the defrost system has failed. Components include the defrost timer, defrost heater, and defrost thermostat. Heavy frost blocks airflow and prevents cooling. A technician can diagnose and replace the failed component ($150-$400).

When to Call a Professional

If you've checked all the above and the fridge still isn't cooling, the issue could be a sealed system problem — a refrigerant leak, failed compressor, or blocked capillary tube. These require specialized equipment and EPA-certified technicians to diagnose and repair. For older fridges (12+ years), compressor replacement may not be cost-effective.

Water pooling under or around your fridge is more than a nuisance — it can damage your flooring and create a slip hazard. Here are the most common causes and how to stop the leak.

Clogged or Frozen Defrost Drain

This is the most common cause. During the automatic defrost cycle, water drips into a drain hole at the back of the freezer and flows to a drain pan underneath the fridge. If the drain is clogged with debris or frozen solid, water backs up and leaks onto the floor. Clear the drain with warm water and a turkey baster, or use a pipe cleaner to remove the blockage.

Damaged or Cracked Drain Pan

The drain pan (located underneath the fridge near the compressor) catches condensation during normal operation. If it's cracked, water leaks onto the floor. Inspect the pan — if it's damaged, replacement pans are available for most models ($20-$50).

Water Supply Line (Ice Maker/Water Dispenser)

If your fridge has an ice maker or water dispenser, the water supply line may be leaking. Check the connection at the back of the fridge and at the water shutoff valve. Tighten any loose connections. If the line is cracked or damaged, it needs replacement ($50-$150 installed).

Damaged Door Gasket

A worn or torn door gasket (seal) allows warm, humid air into the fridge, causing excessive condensation that can overwhelm the drain system. Inspect the gasket for cracks, tears, or gaps. Close the door on a piece of paper — if you can pull it out easily, the gasket isn't sealing properly and should be replaced ($50-$100).

Fridge Not Level

A fridge that tilts forward slightly ensures condensation flows toward the drain. If it's level or tilting backward, water can pool inside and leak out the front. Adjust the front feet so the fridge tilts very slightly backward.

Opening your dishwasher to find standing dirty water at the bottom is unpleasant — and it means your dishes aren't getting clean. Here's how to diagnose and fix a dishwasher drainage problem.

Check the Drain Filter

Most dishwashers have a removable filter at the bottom of the tub (under the lower spray arm). Food particles, glass shards, and debris accumulate here and block drainage. Remove the filter, rinse it under hot water, and scrub it with a soft brush. Clean the filter area in the dishwasher tub as well.

Check the Air Gap or High Loop

Your dishwasher drain hose needs either an air gap (a small chrome cylinder on your countertop) or a high loop (where the drain hose is secured high under the sink before connecting to the garbage disposal or drain). If the air gap is clogged, remove the cap and clean out any debris. If there's no high loop and the hose goes straight to the drain, wastewater can siphon back into the dishwasher.

Check the Garbage Disposal Connection

If your dishwasher drains through the garbage disposal, make sure the disposal isn't clogged. Also, if the disposal was recently installed, the knockout plug inside the dishwasher drain port may not have been removed — this is a common installation mistake.

Check the Drain Hose

Disconnect the drain hose under the sink and check for kinks, clogs, or food buildup. Run water through it to make sure it's clear. If the hose is damaged or cracked, replace it ($20-$50).

Check the Drain Pump

The drain pump pushes water out of the dishwasher. If the pump impeller is blocked by a piece of food, bone, or broken glass, it can't drain. Access the pump from inside the dishwasher (usually under the filter area) and check for obstructions. If the pump motor has failed, replacement costs $150-$350.

When your brownies are burnt on the bottom and raw on top, or one side of a baking sheet is golden while the other is pale, your oven has an even-heating problem. Here's what causes it and how to fix it.

Faulty Heating Element (Electric Ovens)

Electric ovens have two heating elements — the bake element (bottom) and the broil element (top). If one has burned out, the oven heats unevenly. Turn on the oven and visually inspect both elements — they should glow a consistent, bright orange/red. If one has dark spots, visible breaks, or doesn't glow at all, it needs replacement. Heating element replacement costs $150-$350 installed.

Malfunctioning Temperature Sensor

The temperature sensor (a thin metal probe inside the oven cavity) tells the control board when to cycle the heating elements on and off. If it's faulty, the oven may not maintain the correct temperature, causing uneven heating. You can test accuracy with an oven thermometer. Sensor replacement costs $100-$250.

Faulty Thermostat or Control Board

In older ovens with mechanical thermostats, the thermostat itself can lose calibration over time. In newer electronic ovens, the control board regulates temperature. A faulty control board can cause temperature fluctuations and uneven heating. Control board replacement is $250-$500.

Gas Oven Issues

Gas ovens naturally have more temperature variation than electric ones, but if the burner flame isn't spreading evenly, the burner tube may be partially clogged or damaged. A technician can clean or replace the burner assembly ($150-$400).

Simple Tips for Better Results

• Preheat the oven fully — don't put food in early
• Use the middle rack for most baking
• Rotate pans halfway through cooking
• Don't open the door frequently — each opening drops the temperature significantly
• Use an oven thermometer to verify the set temperature is accurate

When your fridge stops cooling, your furnace quits in January, or your washer floods the laundry room, you need help fast. Same-day appliance repair service is designed for exactly these situations. Here's how it works and what to expect.

How Same-Day Service Works

Call or message early. Same-day availability depends on scheduling. The earlier you reach out (ideally by mid-morning), the better your chances of getting a same-day appointment. WhatsApp messages are often the fastest way to get a response.

Describe the problem. When you contact us, provide the appliance type, brand, model number (usually on a sticker inside the door or on the back), and a brief description of the problem. This helps the technician bring the right parts.

Get a time window. We'll give you a 2-3 hour window for the technician's arrival. You'll get a heads-up call or message when the technician is on the way.

What to Expect During the Visit

Diagnosis: The technician will inspect the appliance, identify the problem, and explain what's wrong in plain language. At Fateh HVAC, we charge a flat diagnostic fee that's waived if you proceed with the repair.

Upfront pricing: Before any work begins, you'll receive a flat-rate price for the repair — including parts and labour. No surprises, no hidden fees.

On-the-spot repair: For common problems, we carry the most frequently needed parts on our trucks. About 80% of repairs are completed in the first visit.

When Same-Day Isn't Possible

Some situations require special-order parts or multiple visits. If the part isn't in stock, we'll order it and schedule the follow-up as quickly as possible. For older or rare appliances, part sourcing can take a few days. We'll always keep you informed of the timeline.
