When the air conditioning quits in Mountain View, CA, the house tells you fast, and so does everyone in it. The most common failure we see is the humble run capacitor: a few dollars of electronics that starts the compressor and fan, weakens quietly for years, and finally lets go on a brutal afternoon, leaving the outdoor unit humming but the fan still. Right behind it come pitted contactors that no longer pass power cleanly, condenser fan motors with dry bearings, refrigerant leaks that slowly bleed the system's capacity away, and evaporator coils that freeze into a block of ice whenever airflow collapses behind a clogged filter.

When to Call for AC Repair in Mountain View
Recognizing the warning signs early can save you time and money. These are the signals our technicians see most often:
- An iced-over evaporator coil or frozen refrigerant lines
- Cooling bills climbing while the house stays sticky and warm
- Room-temperature air from the registers even though the AC is running
- Breaker trips or a burning odor at startup
- Bubbling or hissing noises that point to a possible refrigerant leak
- Rapid on-off cycling that never brings the temperature down
- Clicking or humming outside with no fan movement
- Puddles near the air handler or water stains on the ceiling beneath it
