Is it a $30 part or a $3,000 job?

The most common air-conditioning failure in America is a part that costs less than lunch. Here is what every repair costs — the component and the bill, side by side.

A run capacitor costs $8–45. The bill is $80–400. That gap is not a scandal — a contractor's time, van, licence and warranty are all real. But you should know which side of it you are on before the conversation starts, and that is the only thing this page exists to tell you.

Every repair, with both numbers

The call-out alone is $100–$250 before anyone touches anything, plus $40–80/hr on top, evenings and weekends. Worth remembering when the fix turns out to be a filter.

Two things worth more than any repair instructions

A refrigerant recharge without a leak search is a subscription, not a repair. Refrigerant is not consumed. A system that is low has a leak, and topping it up without finding that leak guarantees you will be paying again next summer. This is the most common way homeowners quietly overpay in this trade.

Compare every repair quote to $3,800–$7,500 — the cost of a whole new system. It makes a $400 capacitor quote obviously absurd, and it makes a $2,800 compressor quote on a twelve-year-old unit a genuine argument rather than a foregone conclusion.

Where these numbers come from

Every figure here is curated and sourced by hand, and each repair page lists what it came from. Nothing on this page is generated by a language model — a made-up price would destroy the only thing this page is for. Prices are ranges because real prices vary by region, by season, and by how urgent you sound on the phone.

If a number looks wrong for your area, it may well be. Tell us and we will check it.
