What to Look For

Some of these come on suddenly. Others build slowly until something stops working entirely:

The system runs but the air coming from the vents isn’t actually cold
Airflow from registers is weak even with the blower running
Ice on the indoor air handler or on the refrigerant lines outside
Short cycling: the system turns on, runs briefly, shuts off, and repeats
Grinding, rattling, banging, or squealing sounds during operation
Water near the indoor unit or moisture stains on nearby walls or ceilings
Burning smell or the circuit breaker trips when the AC starts
Utility bills that have spiked without any real change in usage

Walnut Creek’s housing mix creates a range of repair situations. Downtown condos with package units on rooftops or wall-mount systems have different failure modes than central systems in the larger hillside homes. We work in both regularly. If you’re in a building where the equipment is shared or access requires coordination with property management, let us know when you call and we’ll plan around it.
