A humming outdoor unit with a fan that will not turn is the call we get most in July in Loveland, CO, 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.

Signs You Need AC Repair in Loveland
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Cooling bills climbing while the house stays sticky and warm
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Rapid on-off cycling that never brings the temperature down
- 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
- A condenser fan that sits still while the outdoor unit hums
- Room-temperature air from the registers even though the AC is running
- Water leaking around the indoor unit or from the ceiling below it
