The outdoor unit was humming, but the fan on top was not turning, and the house had no cool air. That is how a homeowner in Van Buren described the problem when they booked a visit with us online in early September.
What Our Technician Found
A hum with no fan movement is a classic sign of a capacitor problem. The capacitor gives the compressor and the outdoor fan motor the boost they need to start and keep running. When it fails, the motors try to start but cannot, and you hear that hum.
Capacitors wear out over time, and heat is hard on them. A long Arkansas summer puts a lot of strain on this small part, which is why a failed capacitor is one of the more common reasons an air conditioner stops cooling.
Our technician traced the problem to the capacitor and replaced it. While checking the system over, he also found that both coils were overdue for a good cleaning.
What We Completed
- Replaced the failed capacitor with a new one matched to the equipment.
- Took the outdoor unit apart and deep cleaned the outdoor coil and cabinet.
- Deep cleaned the indoor evaporator coil.
Why Clean Coils Matter
Your air conditioner has two coils. The indoor coil pulls heat out of the air in your home, and the outdoor coil releases that heat outside. When dust and dirt build up on either one, heat cannot move the way it should. The system runs hotter, runs longer and works harder, and that extra strain is tough on parts like capacitors and motors.
The Result
With a new capacitor and two clean coils, the system has what it needs to run the way it should. You can see the difference in the before-and-after photos of the indoor coil. Learn more about our AC repair service.
What Homeowners Can Learn From This Job
- Listen to your outdoor unit. A hum with a fan that will not spin usually means it is time to call for service.
- Turn the system off. If you hear that hum, shutting the system off can protect the motors until help arrives.
- Dirty coils cost you. A clean system costs less to run and tends to break down less often.
