Why Won’t My AC Stay on in Harrisburg, NC?

When your AC in your Harrisburg, NC home repeatedly shuts off, you probably get frustrated because your comfort suffers greatly. To preserve system longevity and lower your energy costs, you must quickly figure out why your AC won’t stay on.

Thermostat Issues

Thermostat issues are a common cause of air conditioners not staying on. You must check that your settings are correct and that the device does not have a malfunction of some sort.

The location of your thermostat also matters. If you place it in an area that is warmer than most of your house, for instance, then it will give false readings. This can cause your AC to continue running because it won’t reach the target temperature and the rest of the house will feel much cooler.

Clogged Air Filter

Debris that is clogging a filter restricts the airflow and can cause the system to overheat. It will shut down as a safety measure to prevent total burnout. Change your filters monthly, especially if you have a large household with several people and pets.

Low Refrigerant

Refrigerant leaks, which lead to lower levels, will also cause the system to shut off. This is because the system has to work much harder to reach its target. Ice on the coils or hissing sounds are dead giveaways that you have a refrigerant leak.

Electrical Problems

Electrical problems can lead to premature shutdowns because these interrupt power to the AC. You may have a malfunctioning capacitor or faulty wiring, or your relay may have issues.

When to Call a Professional

There are some basic troubleshooting steps that you can take to remedy the problem. If you have not changed the filter in a while, do so straight away.

Also, make sure your thermostat is set to cool your home and is at your target temperature. If these troubleshooting steps do not work, you must call an HVAC maintenance professional straight away.

What Happens During a Service Call?

During your service call, the technician will thoroughly look over your system and test all its parts. Once they find what is wrong, they will tell you and go over your options for fixing it.

Do not think that this problem will disappear because you ignore it. The longer you wait to find out why your AC won’t stay on, the more you risk system damage. Call Dulin Mechanical Services, Inc. for HVAC repair and restore the cooling in your home.
