In this guide, we'll outline the most common HVAC repair costs to help you budget with confidence. We'll also explore HVAC maintenance prices and explain how regular maintenance can help keep repair fees to a minimum.

How Much Does HVAC Repair Cost?

HVAC repair costs depend on various factors, including the scale of the problem and the unit type. According to HomeGuide, the average cost of an HVAC repair is around $293 (CAD 405), with most homeowners spending between $144 and $451 (CAD 199 to CAD 624). You could pay as much as $2,900 (CAD 4,010) for complex or time-consuming jobs.

Some HVAC repair companies charge flat rates for their services, which means you'll know what your job will cost upfront. Others charge by the hour, so the total price depends on how long it takes to resolve the issue. As a rule of thumb, you should expect to pay a service call fee of around $75 to $200 (CAD 104 to CAD 277), which usually covers the first hour. After that, you'll pay the technician's hourly rate. These rates can vary by area but often range between $100 and $150 (CAD 138 and CAD 207).

Remember to check whether your system is in warranty when planning HVAC repairs. Depending on the terms, your warranty may help reduce the cost of repairs by covering the cost of replacement parts, although homeowners will often need to pay for labor out of pocket. However, some premium HVAC warranties also cover repair labor for a set period.

How Much Does It Cost to Service a Furnace?

This Old House estimates that furnace repair costs between $140 and $400 (CAD 194 and CAD 553). Prices can increase to $2,000 (CAD 2,765) or more if you need to replace an expensive component to get your furnace running again. Repair and replacement costs often vary significantly depending on the broken component involved.

Furnace Motor and Heating Parts

Repairing a furnace blower motor typically costs between $150 and $450 (CAD 207 to CAD 622), while a full replacement is a larger investment at $850 to $2,000 (CAD 1,175 to CAD 2,765).

The heat exchanger, a critical component, costs between $325 and $1,025 (CAD 449 to CAD 1,417) to repair, though replacing it entirely can cost anywhere from $500 to $2,000 (CAD 691 to CAD 2,765).

Furnace Gas and Ignition Systems

Issues with the gas valve can be addressed for an average repair cost of $160 (CAD 221), while a replacement of this part averages $735 (CAD 1,016). Other ignition-related components are typically replaced outright. For example, gas ignitors are usually replaced rather than repaired. This generally costs $150 to $270 (CAD 207 to CAD 373). A thermocouple replacement is one of the more affordable ones, at $125 to $250 (CAD 273 to CAD 346).

Electrical and System-Wide Furnace Parts

The circuit board is vital for furnace operation, and it's another part that is generally replaced rather than repaired. Expect to pay $275 to $770 (CAD 380 to 1,065) to replace a circuit board. If the furnace coil fails, replacement costs between $600 and $2,000 (CAD 830 to CAD 2,765). And if you need to replace or upgrade your furnace's thermostat, this costs betwen $110 and $540 (CAD 152 to CAD 747).

Furnace Repair Costs By Fuel Type

The type of furnace you have can also impact the price. Generally, electric furnaces are significantly cheaper to repair, typically costing between $50 and $300 (CAD 69 and CAD 415). Gas and propane models are costlier at $300 to $1,200 (CAD 415 to CAD 1,659) per repair.

How Much Does It Cost to Service an Air Conditioner?

According to pricing data from Fixr, most homeowners spend between $250 and $700 (CAD 346 and 968) on AC repairs, with an average job costing around $375 (CAD 518). Straightforward repairs could cost as little as $75 (CAD 104), while part replacement can reach $3,000 (CAD 4,148).

The type of air conditioner you have will likely impact the repair cost. Some common air conditioner types in the United States (and the costs to repair them) are:

Window air conditioner: $75 to $350 (CAD 104 to CAD 484)
Portable air conditioner: $80 to $350 (CAD 111 to CAD 484)
Central air conditioner: $150 to $2,000 (CAD 207 to CAD 2,765)
Mini-split air conditioner: $300 to $1,000 (CAD 415 to CAD 1,383)

Bear in mind that the age of your equipment can also affect AC repair costs. Newer systems tend to develop less complex faults, which means that repairs are unlikely to exceed $700 (CAD 968). Older units may develop more expensive problems due to wear and tear, and replacement parts may be harder to source. In some situations, it's more cost-effective to replace a worn-out system if it requires costly repairs or keeps breaking down.

Fixing a clogged condensate line is one of the least costly air conditioner repairs, costing $75 to $250 (CAD 104 to CAD 346) on average. Recharging the refrigerant costs $100 to $600 (CAD 138 to CAD 830), while repairing a faulty motor blower costs $200 to $900 (CAD 277 to CAD 1,244). Repairing a refrigerant leak is more expensive, costing homeowners between $200 and $1,500 (CAD 277 and CAD 2,074).

Your HVAC professional may recommend replacing broken parts to reduce repair fees. While you'll need to pay for a new part and installation labor, replacing a part is usually significantly faster. Some AC components are impossible to repair, making replacement the first-line option.

Let's explore the cost to replace common AC parts:

Fuse: $75 to $300 (CAD 104 to CAD 415)
Relay switch: $75 to $300 (CAD 104 to CAD 415)
Condensate pump: $100 to $500 (CAD 138 to CAD 691)
Circuit board: $100 to $700 (CAD 138 to CAD 968)
Thermostat: $150 to $500 (CAD 207 to CAD 691)
Expansion valve: $300 to $500 (CAD 415 to CAD 691)
Blower motor: $300 to $2,000 (CAD 415 to CAD 2,765)
Evaporator coil: $400 to $2,700 (CAD 553 to CAD 3,733)
Condenser coil: $600 to $2,400 (CAD 830 to CAD 3,318)
Compressor: $600 to $3,000 (CAD 830 to CAD 4,148)

Heat Pump Repair Costs

Minor heat pump repairs, like flushing the drain lines, replacing a fuse or recharging the Freon, cost between $150 and $650 (CAD 207 and CAD 899), according to HomeGuide. Replacing a major part, such as the evaporator coils or condenser coil, can cost up to $2,500 (CAD 3,457) or more.

Like other types of HVAC equipment, repairing a newer heat pump is usually more affordable than fixing an older model. Larger systems are often more expensive to repair, so you should budget toward the upper end of the price range if you have a large model.

Ductwork Repair Costs

HomeGuide says that small-scale duct repairs usually cost $200 to $700 (CAD 277 to CAD 967). If the problem is more severe, you may need to reseal or completely replace the broken section. Sealing air ducts costs between $400 and $2,700 (CAD 553 and CAD 3,733), depending on whether you choose manual or aeroseal sealing. Manual sealing is usually the most cost-effective option, but it may not be feasible for every setup.

Your HVAC technician may recommend applying Duct Armor or a similar rubberized sealant if your ductwork is extensively damaged. This type of sealant is much more expensive at $5,000 to $30,000 (CAD 6,913 to CAD 41,478) for an entire system, but it could be worthwhile if your existing ductwork is very old or in poor condition. Applying rubberized sealant can recondition your ducts, allowing you to avoid a large-scale replacement.

The cost to repair ductwork by replacing damaged sections depends on the severity of the issue. Duct replacement costs $25 to $55 (CAD 35 to CAD 76) per linear foot, or $270 to $500 (CAD 373 to CAD 691) for a duct run.

Emergency Heating Repair Services

As you might expect, 24-hour emergency heating services cost more than hiring an HVAC company during normal service hours. Emergency air conditioner repairs usually cost $150 to $300 (CAD 207 to CAD 415) per hour. The costs to repair other types of HVAC equipment outside regular business hours are similar.

How Much Does HVAC Maintenance Cost?

Maintaining your system can help you reduce or avoid HVAC repair costs. During your maintenance appointment, your technician will inspect your system to detect hidden issues, enabling you to fix them before they escalate into bigger, more expensive problems. They'll also perform routine maintenance tasks to keep your system running smoothly and reduce the risk of faults developing.

How much HVAC maintenance costs depends on the type and size of your system and whether you purchase a maintenance contract. Most HVAC companies charge around $275 (CAD 380) for a one-off tune-up appointment, with most homeowners paying between $150 and $350 (CAD 207 and CAD 484).

You'll usually need to perform HVAC maintenance once a year. However, some systems require more frequent maintenance, so you should check your owner's manual to help you determine the best schedule. Your HVAC maintenance company can also provide advice if you're unsure.

Split System HVAC Maintenance Services

Many American homes have a split heating and cooling system, which means your HVAC company will need to inspect and maintain both parts. Split system maintenance usually costs $200 to $600 (CAD 277 to CAD 830).

AC Cleaning and Maintenance Services

Maintaining a single AC system is usually more affordable than a split system. Packaged systems contain both heating and cooling equipment in the same unit and cost between $450 and $550 (CAD 622 and CAD 760) to maintain. Maintaining a mini-split AC costs $300 to $550 (CAD 415 to CAD 760), while professional maintenance for a central air conditioner is significantly cheaper at $70 to $200 (CAD 97 to CAD 277).

Furnace Maintenance

Professional furnace maintenance starts from around $70 (CAD 97) for a straightforward appointment. Prices can increase up to $300 (CAD 415) if the technician detects a problem with your furnace while inspecting your equipment.

Heat Pump Maintenance

Maintaining a heat pump is relatively inexpensive per visit at $75 to $150 (CAD 104 to CAD 207). That's because heat pumps usually have fewer moving components than furnaces and AC units and run more efficiently, making them quicker to inspect and less prone to wear and tear. However, most manufacturers recommend professional maintenance twice per year, which will increase your yearly costs.

Air Duct Cleaning Services

Air duct cleaning removes contaminants and debris from your ductwork, improving your indoor air quality and allowing your HVAC system to work more efficiently. The national average cost of duct cleaning is around $500 (CAD 691), with most homeowners spending between $300 and $700 (CAD 415 and CAD 968).

The size of your home can affect the cost of AC duct cleaning. Companies that calculate costs by home size typically charge $0.15 to $0.35 (CAD 0.21 to CAD 0.48) per square foot. Alternatively, your company may charge a flat rate per vent and return. Cleaning a single vent usually costs $25 to $50 (CAD 35 to CAD 69), while cleaning a return costs around 75 (CAD 104).

HVAC Maintenance Contracts

Some HVAC companies offer maintenance contracts, which cover the maintenance services you need throughout the year for an annual fee. It's worth checking which services your contract includes before committing to ensure it meets your needs. Many maintenance plans include at least one tune-up per year, discounts on other HVAC services and preferred scheduling. Costs vary widely between companies and geographic locations, but most people pay between $150 and $500 (CAD 207 and CAD 691) per year.
