A malfunctioning AC unit can be quite an inconvenience during the hot season. If you notice that your AC unit isn't heating the house, make sure you consult an AC unit technician immediately. The following are some reasons your AC isn't heating your home.

Clogged Air Filter

One of the reasons your AC unit is blowing cool air is because of a dirty or clogged air filter. Make sure you visually inspect your air filter. If you notice some debris or dirt, change the filter. Changing the air filter more often produces cleaner air and ensures proper air flows through your AC unit.

Faulty Compressor

A compressor is an important component in your air conditioning unit responsible for cooling your room. If the air conditioner isn't producing cool air, the compressor may be faulty. The compressor compresses the refrigerant and circulates it through the AC's coils. If the compressor malfunctions, this cooling cycle will not start, and your AC unit won't cool your house. In some cases, the problem may be with either the evaporator or condenser coils. However, if replacing these coils doesn't resolve the issue, your technician may install a new compressor.

Wrong Thermostat Settings

When your thermostat has improper settings, you will not get any cool air. The thermostat controls your AC's functioning efficiency. Adjusting the right thermostat temperature can be a challenge sometimes. You may have to consult a technician to achieve a comfortable cooling temperature.

First, try lowering the thermostat temperature by a notch and see whether there is a difference. If you don't notice any change, try experimenting with the thermostat settings until you find an optimum temperature level. If the problem persists, call an AC system technician to repair the thermostat.

Low Refrigerant

The AC system's refrigerant absorbs heat from the air. If you have insufficient refrigerant, your AC unit will not be cool enough. One of the reasons your air conditioner will run out of refrigerant is a leakage.

If you notice hissing or bubbling noises, it means your air conditioner has a refrigerant leak. Although your AC unit will still operate when you have a refrigerant leak, the temperature will not be as comfortable. Make sure you contact a technician to fix the leak and restore the refrigerant levels.

In Closing

You should schedule air conditioner maintenance to prevent minor problems that may lead to expensive repairs. Besides the AC unit not heating your house, you may experience other problems like bad odor and annoying noises. You should also ask your technician to enlighten you on some signs that your AC unit is malfunctioning and tips for prolonging your AC system's lifetime.
