A humming outdoor unit with a fan that will not turn is the classic summer service call in Pearland, TX, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.
When the heat goes out, see Furnace Repair.
Signs You Need AC Repair in Pearland
Recognizing the warning signs early can save you time and money. Here are the most common indicators that it's time to call a professional:
- Water leaking around the indoor unit or from the ceiling below it
- Cooling bills climbing while the house stays sticky and warm
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- An AC that turns on and off every few minutes but never cools down the house
- Clicking or humming outside with no fan movement
- Room-temperature air from the registers even though the AC is running
- Breaker trips or a burning odor at startup
- Ice on the refrigerant lines or a frozen indoor coil
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, call (281) 270-0195 for a prompt inspection.
