If your air conditioner quit in the middle of a July heat wave, the first question is always the same: how much does AC repair cost? In 2026, most homeowners pay between $150 and $650 USD for a common repair, with the national average around $350. In Canada, most fixes land between $150 and $1,500 CAD, depending on the part and the region. Minor fixes like a capacitor swap can run under $250, while a failed compressor can push past $2,500 — which is why knowing the typical range before the technician arrives matters.
Here’s what drives the price, what each common repair costs in the US and Canada, and how to decide between repairing and replacing.
What Affects AC Repair Cost
Four things move the number more than anything else:
- The part that failed. A clogged drain line is a quick, cheap visit. A compressor is the heart of the system and priced accordingly.
- Timing. Emergency, evening, weekend, or heat-wave calls often run 1.5–2x the standard rate. If your AC limps but still cools, booking a regular weekday slot saves real money.
- The age of your unit. Older systems that use phased-out R-22 refrigerant cost far more to recharge because supply is scarce. Units older than 10–12 years also fail in clusters — fix one part and the next goes.
- Where you live. HVAC labour runs roughly $100–$250/hour in most US metros and $120–$160/hour in areas like the Greater Toronto Area. Hot markets in peak season book out and price up.
AC Repair Cost by Type of Repair
Typical 2026 price ranges, parts and labour included. US and Canadian ranges are similar in their own currencies (USD in the US, CAD in Canada):
| Repair | Typical range (USD/CAD) |
|---|---|
| Diagnostic / service call | $75 – $200 |
| Condensate drain line clearing | $75 – $250 |
| Capacitor replacement | $120 – $300 |
| Thermostat replacement | $150 – $500 |
| Refrigerant leak repair + recharge | $200 – $1,500 |
| Fan motor replacement | $300 – $800 |
| Circuit board replacement | $200 – $600 |
| Compressor replacement | $1,000 – $3,000 |
| Annual tune-up (preventive) | $100 – $300 |
Many companies waive the diagnostic fee if you go ahead with the repair — always ask.
Repair or Replace?
Two rules of thumb the industry uses:
- The 50% rule: if the repair costs 50% or more of a new unit, replace.
- The $5,000 rule: multiply the unit’s age by the repair quote. Over $5,000 (e.g., a $600 repair on a 10-year-old unit), replacement is usually the better spend.
Replacement also unlocks efficiency gains — and in Canada, heat-pump upgrades may still qualify for rebates. We covered what’s available in our guide to home energy rebates in Canada.
DIY vs. Hiring a Pro
Safe DIY checks before you call anyone: replace the air filter, check the breaker and the outdoor disconnect, clear leaves and debris from around the condenser, and make sure the thermostat is set to cool with fresh batteries. These fix a surprising number of “broken” ACs for free.
Everything else — refrigerant, electrical components, motors, anything requiring the panel to come off — is licensed-pro territory. Refrigerant handling is regulated in both the US (EPA Section 608) and Canada, and DIY electrical work on a condenser is genuinely dangerous.
How to Vet an HVAC Pro
- Confirm licensing and insurance for your state or province — HVAC is a regulated trade almost everywhere.
- Get 2–3 written quotes for anything beyond a basic service call; quotes for the same compressor job can vary by $1,000+.
- Be wary of a tech who pushes full replacement without showing you the failed part or the readings. Pressure tactics are a red flag we discussed in what a new poll reveals about contractor fraud.
- Check reviews and response time — in peak season, a pro who answers in Phoenix or Toronto within a day is worth a modest premium.

Frequently Asked Questions
How much does it cost to fix an AC unit?
Most common AC repairs cost $150–$650 in the US and $150–$1,500 CAD in Canada, with the average around $350. Major repairs like a compressor can reach $3,000.
Why is AC repair more expensive in summer?
Demand peaks during heat waves, so emergency and after-hours calls carry a 1.5–2x premium. Booking a standard weekday appointment — or a spring tune-up before the season — costs less.
Is it worth repairing a 12-year-old air conditioner?
Usually not for major repairs. Central ACs last 12–17 years; if the repair quote times the unit’s age exceeds $5,000, replacement is typically the smarter investment.
How much is an AC service call or diagnostic fee?
Expect $75–$200, and many companies credit that fee toward the repair if you hire them for the job.
