What drives the price
Nearly every AC call starts with a diagnostic or trip fee of $75-$150. From there the price is driven almost entirely by which part failed — the parts themselves are often cheap, but refrigerant handling requires EPA certification and specialized gauges.
- Which component failed (capacitor is cheap, compressor is not)
- Refrigerant type — older R-22 systems cost far more to recharge
- Whether the diagnostic fee is credited toward the repair
- Peak summer emergency scheduling
- Age of the system — parts for units over 15 years may be scarce
Should you DIY this or call a professional?
Call a pro for anything involving refrigerant — it is federally regulated and you need certification to buy or handle it. You can safely do the free checks first, though: replace a clogged filter, clear leaves and debris from the outdoor condenser, and confirm the breaker has not tripped. Those three account for a large share of 'broken' ACs.
Signs you need this repair
- Blowing warm air while the unit is running
- Outdoor unit hums but the fan does not spin
- Ice on the copper refrigerant lines
- Short cycling — turning on and off every few minutes
- A sharp rise in your electric bill with no usage change
How to not get overcharged
Always ask whether the diagnostic fee is waived or applied to the repair if you proceed. Most companies will do this if asked but will not offer it. If you are quoted a compressor replacement on a system over 12 years old, get a second quote that prices full replacement — repairing an old compressor is often throwing money at a system that will fail again.

Red flags to watch for
- Recommending full system replacement on the first visit without a diagnostic report
- 'Your refrigerant is low' with no leak search — refrigerant is a closed loop, low means there is a leak
- Refusing to show you the failed part
- Vague 'tune-up' packages with no itemized scope
