Why does this happen, and more importantly, is it telling you to give AC repair Blue Spring, MS a call? 

Let’s take a look at some of the most common reasons why your air cooling system might be freezing, along with basic tips on how you can troubleshoot it.

  • Blocked Air Flow

One common reason for an AC to freeze is due to blocked airflow. This can happen if the air filter is dirty or something is blocking the vents, such as furniture or curtains. You can start by checking the air filter and replacing it if it is dirty. Proceed to the vents to make sure they are clear. If you still can’t get enough airflow, you may need to call a professional AC repair Blue Springs, MS.

  • Dirty Evaporator Coils

Your evaporator coil serves as your air conditioner's “cold” side. It is filled with a coolant that helps remove heat and humidity from the air as it passes over the coils. But over time, these coils can get dirty, reducing their ability to remove heat and eventually causing your unit to freeze up.

You can clean the coils yourself by turning off the power to the unit and removing the coil cover. Use a soft brush to remove dirt or debris, then rinse the coils with water. If you can’t reach all the coils, you may need to hire a professional to do a deep cleaning.

  • Low Refrigerant Levels

If your evaporator coils are clean, but your unit is still freezing up, it could be because the refrigerant levels are low. When there isn’t enough refrigerant circulating through the system, it can cause the coils to freeze.

All you have to do is add more refrigerants to the air conditioning unit. This is an AC repair Blue Springs, MS job best left to a professional, as too much or too little refrigerant can cause further damage to your unit.

  • Thermostat Issues

Some of the newer air cooling systems have thermostats controlled by sensors. If the sensor is not in the correct position, it can cause your unit to freeze up.

To fix this problem, you will have to adjust the position of the sensor. Consult your AC unit's manual or let the technician do the AC repair Blue Springs, MS on your behalf.

  • Damaged Components

Air conditioners are made up of many different components, and if one of these components is damaged, it can freeze up the entire unit. The most common culprits are a damaged compressor or fan.

Compressors and fans can be expensive to replace, so it’s best to call a professional AC repair near Blue Springs, MS if you think either of these components is damaged.

The next time your AC unit freezes up, don’t panic! Most of the time, it is a relatively easy and inexpensive problem to fix. But if you are not comfortable doing the troubleshooting tips on your own or if the problem persists, contact a qualified HVAC technician.
