Emergency AC Repair Cost in 2026
What common AC failures cost
| Repair | Typical cost | Notes |
|---|---|---|
| Capacitor replacement | $180–$400 | The #1 summer failure; 30-minute fix |
| Contactor replacement | $180–$380 | Often paired with capacitor |
| Clogged condensate drain | $150–$300 | Causes shutdowns and ceiling leaks |
| Fan motor replacement | $400–$800 | Condenser or blower motor |
| Refrigerant leak repair + recharge | $600–$1,800 | Leak search adds labor; R-410A prices rising |
| Compressor replacement | $1,500–$3,000 | Usually the repair-vs-replace decision point |
Add $100–$300 to any of these for nights, weekends, or holidays, that's the emergency premium, and in a July heat wave some markets charge more simply because every truck is booked.
What drives your quote up
- Diagnostic fee ($85–$200): Charged on arrival; most companies credit it toward the repair if you proceed. Ask before booking.
- Refrigerant type: Units on phased-out refrigerants cost far more to recharge, and a leak on one is often the economic end of the unit.
- Age of the system: Past 10–12 years, big repairs stop making sense. The rule many techs use: if repair cost × unit age (years) exceeds $5,000, replace.
- Peak-season demand: The same repair costs less in April than in a July heat wave. If the failure isn't urgent, scheduling off-peak saves real money.
Before you call, two free checks
A meaningful share of "dead AC" emergency calls end with a $150 invoice for something the homeowner could have checked: a tripped breaker, or a thermostat with dead batteries. Check both. Also look at the outdoor unit, if ice is visible on the lines, shut the system off and let it thaw for a few hours; running it frozen can turn a cheap fix into a compressor failure.
Repair or replace?
For units under 8 years old, repair almost always wins. Between 8 and 12 years, compare the repair quote against a replacement quote before deciding, a $1,800 compressor job on an 11-year-old unit is rarely good money. Past 12–15 years, major repairs are usually a bridge to a planned replacement at best. New central AC installation runs $3,900–$12,500 depending on size and efficiency; get both numbers side by side before signing anything in a heat wave.
