Why Is My Air Conditioner Freezing Up?

Published: August 1, 2021

There is nothing more frustrating than your AC not cooling your house. After all, that’s its entire purpose! There are many causes that can make your air conditioner freeze up. Here are the main reasons you are experiencing difficulty with your air conditioner and the quick solutions, if available, to fix them.

Blocked Air Flow

Air conditioners always need a constant flow of air to function properly. This flow is blocked mainly due to dirty filters. It can seem like a tedious process to buy the filter and install it, but it’s actually quite easy and incredibly necessary in order for your air conditioner to function. For a tutorial on how to change out your air filter, click here.  If you have any questions or difficulty replacing your air filter, contact Service Tech for assistance.

Refrigerant Leak

Air conditioners have many parts, one of those being refrigerant lines. If your refrigerant lines even have a kink in them, that’s enough to cause a multitude of issues, including leaking. If leaking occurs, it can cause your refrigerant to become too cold. Unfortunately, the fix isn’t as easy as replacing an air filter. Any solution you come up with is likely just delaying the inevitable: It may be time to get a new air conditioner. It is extremely important to have a professional come take a look at your air conditioner if you suspect a leak or damage to any of the parts within your air conditioner.

Cooler Than Usual Temperatures

As mentioned before, air conditioners are pretty sensitive, so anything out of the ordinary can affect their functionality. If you’re experiencing a cooler than usual temperature, especially in the summer when it’s supposed to be hot, your air conditioner can get confused because they are designed to operate within a specific temperature threshold. The easiest way to fix this is by installing a programmable thermostat that will turn off the AC if the temperature goes below the threshold. If you’re unable to get a programmable thermostat, you can always consistently monitor the temperature and manually turn off the air conditioner if necessary. 

Air Conditioner Control

When it comes to your air conditioner functioning properly, the most important thing to remember is that regular maintenance is essential. If you are regularly replacing your air filters when they get dirty, it will go a long way. If you are unable to figure out the issue on your own, be sure to reach out to the professionals at Service Tech. We would be happy to repair your unit and give guidance on taking care of your air conditioner.
