Most AC breakdowns in Tigard start with a small part: the run capacitor. It helps start the compressor and condenser fan, loses strength slowly over the years, and tends to give out on the hottest afternoon, which is why so many service calls begin with an outdoor unit that hums while the fan sits motionless. Other frequent culprits include contactors with pitted, burned points, fan motors whose bearings have run dry, slow refrigerant leaks that steadily rob capacity, and evaporator coils that turn into blocks of ice once a dirty filter chokes the airflow.

Warning Signs for AC Repair
Recognizing the warning signs early can save you time and money. These are the signals our technicians see most often:
- An AC that turns on and off every few minutes but never cools down the house
- Higher summer bills even though the house still feels warm and humid
- Water dripping from the indoor unit or showing up on the ceiling below
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Clicking or humming outside with no fan movement
- Breaker trips or a burning odor at startup
- Bubbling or hissing noises that point to a possible refrigerant leak
- An iced-over evaporator coil or frozen refrigerant lines
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. At the first hint of a problem, call (971) 535-9452 for a fast inspection.
