Expert AC Repair

A broken air conditioner during a Bay Area heatwave is miserable. San Bruno HVAC Service delivers fast, same-day AC repair so you're never stuck in the heat.

Common Causes of AC Failure

Low Refrigerant: Leaks in the copper lines cause the system to blow warm air and can freeze the coils.
Electrical Malfunctions: Faulty capacitors, blown fuses, or bad contactors stop the compressor from running.
Dirty Air Filters: A severely clogged filter suffocates the system, causing it to overheat and shut down.
Frozen Coils: Usually the result of poor airflow or low freon, leading to complete cooling failure.
Thermostat Issues: The thermostat fails to communicate properly with the main control board.

FAQs About AC Repair

Common questions from San Bruno homeowners.

This is one of the most common AC problems and is usually caused by a refrigerant leak, a severely clogged air filter, or a dirty outdoor condenser coil preventing heat transfer.

The cost depends on the location of the leak and how much R-410A refrigerant needs to be recharged. We use electronic leak detectors to find the exact pinhole and provide a flat-rate quote before repairing the copper line.

This is called short cycling. It can be caused by an oversized AC unit, a malfunctioning thermostat, or low refrigerant pressure triggering the low-pressure safety switch to shut the system down.

Generally, if an AC unit is over 12-15 years old and the repair costs more than 30% of a replacement system, it is more financially sound to upgrade to a modern, energy-efficient model. We offer honest assessments to help you decide.

San Bruno HVAC Service is top-rated by local homeowners for our transparent pricing, fast dispatch times, and highly trained technicians who can fix all major air conditioning brands.
