How Much Does Air Conditioner Repair Cost?

In Toronto, AC repair cost typically ranges from $100 to upwards of $600, but the final price depends on:

We get it. Nobody wants to get hit with a surprise bill after you’ve already suffered from an AC malfunction—especially in the middle of a Toronto heatwave! But air conditioner repair can be unpredictable. Some problems only need a few simple tweaks, while others require a more extensive (and expensive) process. 

So, how much should you expect to pay? Keep reading, because we’re breaking down everything that goes into your AC service cost so you know exactly what to expect!

Factors Influencing AC Repair Cost

As we’ve established, air conditioner repair cost in Toronto can vary widely, and that’s because several factors come into play. Let’s break each of them down.

Type & Severity of the Problem

Not all air conditioning problems are created equal. Different issues with varying repair costs can show similar symptoms.

An AC blowing warm air could mean you’re dealing with a simple air filter replacement or complex compressor failure. Either way, you can only know the actual fix needed and the AC repair cost when a licensed HVAC tech properly diagnoses your system. That said, we can share some industry averages:

AC Repair Cost per Repair Type
Type of Repair Average AC Repair Cost
Refrigerant Leak $195 to $505
Air Filter Change or Cleaning $75 to $200
Frozen Coil $550 to $2,250
Drainage Issue $75 to $250
Electrical Issue $150 to $800

AC Unit Model

There are many types of air conditioning systems, and as their installation costs vary, so do repairs. Portable and window-type AC systems are often simpler and more affordable to fix because of their smaller size and less complicated technology. The opposite goes for central AC and ductless mini-splits. 

Repairing air conditioner types with advanced technology and additional components like electronic expansion valves or smart control systems often requires higher skill levels and service contract costs. For more sophisticated models, diagnostic times alone can eat away at your budget, especially if intricate components and electronic systems are involved.

AC Unit Age

The more depreciated a unit is, the higher the AC repair cost. That’s why older models or units  10 years or older are often more expensive to repair. They’re commonly more worn, have higher chances of wear and tear, and might need outdated parts. Often, it’s smarter to upgrade to a new, better AC

Parts & Materials

Another factor considered in air conditioning repair is the cost and availability of replacement parts and materials. Dirty air filters usually cost as little as $10, so they’re easy to swap out. But if your unit needs something major, like your evaporator coil or compressor, you could be looking at $500 at least. 

Some brands and AC models also require proprietary parts from original equipment manufacturers (OEM), which are often expensive and hard to find. Procuring parts for older and discontinued models is even more complicated since they’re no longer widely available. This can further drive up your repair service cost.

AC Repair Cost per Replacement Part
AC System Component Average Cost
Air Filter $10 to $50
Thermostat $100 to $400
Condenser Coil $1,000 to $3,000
Compressor $1,500 to $3,000
Capacitor $200 to $450
Refrigerant Recharge $100 to $320 ($180 to $600 for older units using R22 Freon
Circuit Board $150 to $700
Fan Motor $400 to $600
Evaporator Coil $550 to $2,500

AC Repair Service Provider

Not all HVAC companies charge the same, which is why AC repair costs can vary a lot across Toronto. In repairing air conditioner units, labour makes up a huge chunk of your bill. HVAC technicians in Toronto charge $24/hour on average. Reliable service providers like LG Home Comfort earn their pay through:

  • Extensive training, repair experience, and certifications
  • Warranty on parts and labour
  • Access to quality parts
  • Fast and accurate diagnostics
  • Full liability insurance coverage
  • Proper safety protocols

Beyond their expertise, service timing also affects what you’ll pay. While many air conditioner repairs occur during regular office hours, that isn’t always the case. Emergency service repair on weekends, holidays, and outside regular hours may cost more. 

If your usual HVAC repair service doesn’t operate 24/7, you may have to wait days for repairs. To avoid a terrible fate sweating in the Toronto heat, choose providers with round-the-clock, speedy service. Better if they guarantee same-day or next-day service!
