Why Does My AC System Make My House Hotter in Caroline, VA?

When you turn on the air conditioner, you expect relief from the heat outside your Caroline, VA, home. When your home gets hotter, your AC system isn’t doing what it should. Learn more about why your AC system may blow hot air and make your house hotter.

Low Refrigerant

If there isn’t enough refrigerant in the air conditioner, the system cannot remove heat from your home and create cold air. The cooling system may still operate and blow air through the vents, but the air will be warm or even hot.

Dirty Air Filter

Dirty and clogged air filters can stifle airflow and cause cold air to turn warm before it reaches the vents. Change your air filters every three months to keep them from stopping cold air blowing into your living spaces.

Frozen Coils

Your AC system has coils that help with cold air production and heat exchange. If these coils freeze, you may get hot instead of cold air. Frozen coils may result from excessive dirt accumulation or refrigerant leaks and require professional attention.

Faulty Components

If any components inside your cooling system fail, they could restrict cold air creation or cause warm air to blow through the vents. If the fan goes out, air may only trickle out of the vents and may be warm by the time it reaches them. Likewise, a faulty compressor or heat exchange component can cause warm air to travel through your ducts.

Thermostat Settings

While it may seem obvious, always check your thermostat settings if you aren’t feeling cold air from the vents. Make sure you have the device set to cooling mode.

Some instances of incorrect air temperature result from minor problems you can solve yourself, such as incorrect settings and a dirty air filter.
