AC Unit RunningWhat Do I Do if My AC Unit Keeps Running & Won’t Shut Off?

A constantly-running air conditioning unit isn’t good. It’s usually a sign of something more serious going on with your system. Besides increasing your electric bill, it can do severe damage to the entire system if left untreated. The best thing to do is cut power to the unit at the main breaker. After that, immediately make a service call to Charlie’s Tropic Heating and Air Conditioning. An experienced professional will be able to evaluate the situation and determine the root of the problem. Furthermore, we’ve listed below some reasons an AC unit may keep running.

Dirty Evaporator Coil

Your unit’s evaporator coil could be covered with dirt and debris. This hinders its ability to cool down your space properly. Simply clean it off and see if it’s working properly again.

Clogged Air Filter

When an air filter clogs, it restricts air flow. This means less air will flow over your unit’s coils and extract humidity from the air. As a result, the unit runs constantly trying to cool the space. Regularly replacing your air filter can help eliminate this from occurring.

Low Refrigerant

Low refrigerant can cause the unit to keep running. Refrigerant helps cool the air. Without it, the AC unit can’t keep the space cool enough. A professional can check your refrigerant levels and look for any leaks in the system.

Faulty Thermostat

The reason your AC unit is constantly running might not even be due to the unit itself. A faulty thermostat can cause it to keep running even when the desired temperature is met. If so, just install a new thermostat.

The Unit is too Big or too Small

The size of your home determines how big your HVAC unit needs to be. If it’s too small, it will constantly run to try to cool the space. In contrast, if it’s too large, it won’t run long enough to pull enough moisture from the air. Therefore, consulting with a professional to determine the right size unit to use for your square footage is recommended.

Poor Insulation or Air Leaks

Poorly insulated structures can cause the cold air to escape and warm air to enter. Also, if air is leaking from the ducts before it reaches the vents, your unit will have to work more to compensate. In the end, the best way to know if you’re experiencing any of these issues is through a professional evaluation.

Your Unit is Old & Needs to be Replaced

If your HVAC unit is older and it’s constantly running, it’s probably time to replace it. The team at Charlie’s Tropic can help! Our professionals can recommend a new unit that’s right for your specific structure.

It’s Extremely Hot Outside

Finally, there might not be anything wrong with your unit at all. When it’s hot outside for an extended period, it is going to be harder to keep your indoor temperatures down. Monitor your unit, and if it only runs constantly while it’s hot outside, this is likely the issue.

An HVAC unit running nonstop is never ideal. Consequently, it can cause irreversible damage to your unit that can be costly down the road. If you notice that your air conditioning is continuing to run, an experienced professional at Charlie’s Tropic can identify the issue and find a solution to stop it.
