When the air conditioning quits in Rancho Cucamonga, 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 ice over solid whenever airflow collapses behind a clogged filter.
When the heat goes out, see Furnace Repair.

Spotting the early warning signs lets you act before the problem gets expensive. These are the signals our technicians see most often:
- Cooling bills climbing while the house stays sticky and warm
- Vents blowing air that is barely cooler than the room
- The outdoor unit humming or clicking but the fan not spinning
- Frost or ice forming on the copper lines or the indoor coil
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Bubbling or hissing noises that point to a possible refrigerant leak
- Puddles near the air handler or water stains on the ceiling beneath it
- The system short-cycling every few minutes without cooling the house
