Air conditioning is a real benefit when it comes to surviving our hot and humid summers. But if you’re wondering “why is my AC fan constantly running?” you need to call in a professional right away, as this can drive up your utility bills. Plus, one broken part can quickly start to wear on another.
If it’s particularly hot out or you have your thermostat set to a low setting, there is a chance that your AC might not turn off as frequently as you’re used to. But, if it never stops and your house isn’t cooling down or the thermostat temperature is never met, you have an issue.
While it is best to get professional advice, we’ll walk you through some reasons your inside or outside AC unit runs constantly.
My Air Conditioner Keeps Running
If your AC is running constantly without stopping, it may have any number of issues, including:
- Dirty or frozen evaporator coil
- Clogged or dirty air filter
- Wrong size or type of air filter
- Thermostat not working properly
- Ductwork has leaks or holes in it
- Condenser is dirty or covered with debris
- Issue with the blower motor or fan.
Outside AC Unit Runs Constantly
If you have an outdoor unit it may have a different set of problems. Most commonly, the problem is that the condenser is damaged or frozen or there is debris covering the unit so it can’t take in air. Also, you could have a compressor issue.
Why Does My Air Conditioner Compressor Keep Running?
Is it your air conditioner compressor that is specifically running? The compressor is one of the key parts of the air conditioner, and the most expensive. Therefore, this issue should only be repaired by a trained technician.
However, it may be useful to know that these issues can include:
- Dirty coils
- Blocked suction lines
- Low refrigerant charge
- Incorrect suction line size
- Electrical issues
- Contaminants in the system
- Inadequate oil lubricant.
