What AC Repair Covers
Cooling‑season failures are usually refrigerant, a failed capacitor or contactor, a dirty condenser, or a clogged filter. We diagnose on the first visit and carry those parts on the truck.
A spring AC tune‑up is cheap insurance against the one Bay Area heat wave a year.

The most common causes are low refrigerant from a leak, a failed compressor, a dirty condenser coil, or a tripped breaker cutting power to the outdoor unit. It needs an in‑person diagnostic to identify which one applies.
The diagnostic visit is currently $70 (standard $120 — see Special Offers) and is waived on completed repair. A capacitor is a modest fix; a compressor replacement is not. We quote before starting.
Short‑cycling usually points to an oversized system, a refrigerant charge issue, a dirty coil, or a failing thermostat sensor. It's worth having checked — it accelerates wear on the compressor.
Once a year, ideally in spring before the first hot stretch. Our Maintenance Plan (starting from $199/year) bundles this with priority scheduling.
