Sunnyvale, CA

Air Conditioning in Sunnyvale: what's different

Air Conditioning work in Sunnyvale follows the local climate. Mixed climates get real summers and real winters, so the AC has a full season of work and then sits idle. Spring start-up problems such as weak capacitors, low charge and clogged drains are common.

A common Sunnyvale pattern: eichler radiant heat. In-slab radiant systems can leak and need specialized repair, and Eichlers have no attics for ducts, so ductless heat pumps are the usual way to add cooling. Another: aging ranch-home ducts. Original attic and crawl space ducts often leak and lack insulation, wasting heating and cooling.

The air conditioning services Sunnyvale homeowners ask for most are AC Replacement & Installation. Correctly sized new systems, SEER2 ratings and refrigerant changes.

The City of Sunnyvale Building Safety Division issues mechanical permits, and California requires C-20 licensed contractors and Title 24 compliance. Silicon Valley Clean Energy has offered electrification incentives.

How do I add AC to a Sunnyvale Eichler?+

How do I know if my AC needs repair or replacement?+

Age, refrigerant type and the failed part decide it. A newer system with a bad capacitor or fan motor is a repair. An older R-22 system with a failed compressor or leaking coil is usually a replacement.

Why is my AC running but not cooling?+

Common causes are a dirty filter or coil, low refrigerant from a leak, a failed outdoor fan or capacitor, or a frozen indoor coil. Turn the system off if you see ice and call for a diagnosis.
