Emergency HVAC Repair in Palo Alto, CA

A true emergency is any complete loss of cooling or heating that makes your Palo Alto home unsafe or unlivable. Signs include no airflow at all, the system running but not changing the indoor temperature, or unusual burning smells from the unit.

We inspect the compressor, capacitor, contactor, refrigerant levels, blower motor, and thermostat to find the root cause. For Palo Alto homes with older ductwork, we also check for airflow restrictions that can cause the system to overheat and shut down.
