What it is
Air conditioners sit on their own high-amp circuit, plus a fused disconnect box outside near the condenser. Either can cut power, and the symptom looks identical to a dead system.
What you would notice
- The outdoor unit is completely silent while the indoor fan still runs
- Nothing at all happens when you lower the thermostat
- It died during a storm or a power flicker
Can you do this yourself?
Partly yours
Flipping a breaker back on once is something any homeowner can do. A breaker that trips a second time is not a nuisance, it is a circuit telling you about a fault — a shorted compressor or a failing motor drawing too much current. Resetting it repeatedly is genuinely dangerous.
What to say when you call
Red flags
- Any technician who resets it and leaves without measuring current draw
- A recommendation to upsize the breaker — that is hiding the fault, not fixing it
The call-out alone runs $100–$250 before any work, plus $40–80/hr on top, evenings and weekends. A whole new system is $3,800–$7,500 — compare every quote to that.
Where these numbers come from
- Installed figure is the diagnostic/service-call range
