AC repair in San Mateo County
AC blowing warm? Let's find out why.
A repair visit runs from diagnosis to fix: we test the system, find the part that failed and repair it. On the Peninsula that is most often a refrigerant leak, a dirty or iced coil, a blocked condensate drain or a failed capacitor.
What a repair visit covers
An AC that runs but doesn't cool, short-cycles, ices over or leaks water is telling you something specific. The visit is about finding that one thing, not swapping parts until it works.
-
You tell us what it's doing
Warm air, a new noise, ice on the copper line, water by the indoor unit, a breaker that keeps tripping. The more you can describe, the faster the diagnosis.
-
We test the whole system
Electrical parts first, then refrigerant pressures and temperatures, the coils, the condensate drain and the airflow through the filter and ducts.
-
We repair the part that failed
A capacitor, a contactor, a cleared drain, a cleaned coil, a found and fixed leak: the repair goes at the cause, not the symptom.
-
We run it and check it cools
The system runs through a full cycle before we leave, with the readings checked again.
The faults we see most on the Peninsula
- Refrigerant leaks. Low refrigerant isn't used up, it escapes. Topping it up without finding the leak only buys time.
- Dirty or iced coils. A clogged evaporator coil can freeze solid; a dirty outdoor coil can't shed heat. Either way the house stays warm.
- Blocked condensate drains. Water backs up into the indoor unit or the ceiling, and many systems shut themselves off when the drain pan fills.
- Failed capacitors. The outdoor fan or compressor hums but won't start. It's a common fault and usually a quick repair.
Is it worth repairing an older AC, or should I replace it?
If the fault is a part like a capacitor, a contactor or a blocked drain, repair almost always makes sense, whatever the age of the system.
It's worth pricing a replacement when the compressor has failed, when the system needs refrigerant again and again, or when one repair follows another. A new outdoor unit brings its own rules, and in some Peninsula cities that means a heat pump instead of a new AC.
Either way, we'll tell you what failed and what the choice is, so you can decide.

How do I stop it happening again?
Most of the faults above build up slowly: a coil that clogs over a season, a drain that slimes over, a capacitor that weakens. A tune-up before summer catches them while they are still cheap.
