Why Does My AC Keep Running?
An air conditioner that runs constantly can wear out components and raise energy bills. In San Angelo heat, long run times are normal on the hottest days, but a system that never shuts off may have a problem.
Common Causes
- The thermostat is set very low or is faulty.
- The system is undersized for the home.
- Refrigerant is low.
- Duct leaks waste conditioned air.
- Poor insulation or air leaks in the home.
When to Be Concerned
If the home reaches the set point but the AC keeps running, the thermostat or a control board may be the issue. If the home never reaches the set point, the system may be undersized or low on refrigerant. See AC keeps running.
