Frequently Asked Questions
Why is my AC running but not cooling the house?
The most common causes are a dirty filter, low refrigerant from a leak, a failing capacitor, or a frozen evaporator coil. Turn the system off to prevent compressor damage and call us — we diagnose most San Jose AC problems the same day.
What SEER2 rating do I need in California?
California requires a minimum of 14.3 SEER2 for new central air conditioners in our climate zone. We usually recommend 15.2–17+ SEER2 for San Jose homes — the energy savings over a 15-year lifespan typically outweigh the upfront difference.
How often should my air conditioner be serviced?
Once a year, ideally in spring before the cooling season. A professional tune-up restores lost efficiency, catches failing parts early, and keeps most manufacturer warranties valid.
