AC System Freezes in Shawnee, KS

Your air conditioner is responsible for cooling your whole house and keeping it comfortable throughout the summer. But when your AC unit freezes up, it won’t be able to keep your house comfortable because it is not efficient as it should be. Here’s what to do when this happens.

1. Turn off the Air Conditioner

Turn off your air conditioner but leave the blower when it freezes up. This will prevent the system from continuing to freeze. Don’t switch it on again until the internal unit is thawed and the problem has been addressed. If you turn it on again, your AC unit will freeze again, and the problem will not go away. This may also cause your AC unit to malfunction.

You should also check the blower’s efficiency and motor. If there is a problem with the blower, you need to change the blower’s parts or get the AC unit repaired. A damaged blower might also be the reason your AC freezes.

2. Thaw It

The blower fan will help defrost since it will pull warm air through the coils. It should be let melt by itself.

3. Dry the Coils

Drying the coils is also crucial because they are left wet after thawing. The warm air coming through the coils will make it easy for you to dry out the coils. You should also do this if your AC unit freezes up frequently.

While at this, you should also clean the evaporator coils. This is because their work is to absorb heat from the air, and when there is dirt, it won’t be able to perform. It will cause the refrigerant to cool too much, causing it to freeze.

4. Clean or Replace the Air Filters

The air filters will remove dirt and debris from the air, allergens, and other particles. When the air filters are clogged or blocked, it will be difficult for the AC unit to cool your home correctly because there is no sufficient airflow. When cleaning the air filters, you should check if they are damaged.

If they are not, you can clean them and put them back in. But if they are damaged, then it’s time you should change them. But don’t forget to use the correct size filters.

5.Open all Dampers

Air conditioners use dampers to regulate airflow. And they are used to minimize noise and maintain safe airflow. When they are clogged, keeping your home comfortable will also be difficult because there is not enough airflow.

6. Clean the Ducts and Remove Obstructions From the Vents

You will need to remove the obstructions when there is a clog in the airflow. The most common obstruction is debris that can cause a clog. Other things can cause it, like mold and pests. If you observe these problems, then it’s best to remove them immediately to minimize your problems.

You should also clean the ducts regularly to remove all particles that may block the vents or ducts. This will ensure your system can perform efficiently and keep your home comfortable.

7. Check and Unclog the Condensate Drain Line

Your AC unit will create condensation, which will be drained from the unit to a condensate line. The condensate line is connected to a drain. This line must be unclogged as it may cause the AC unit to freeze.

You must check for any clogs in the line and drain it thoroughly. If you don’t do this, it might cause your coils to freeze from moisture buildup.

8. Call a Certified HVAC Technician to Fix Refrigerant Leak

A low refrigerant level can also cause your AC unit to freeze. You should check the refrigerant level; if it’s low, you need to add more refrigerant. Leaks are responsible for low refrigerant levels.

Your AC unit will not be able to cool even after doing all these things if there is a refrigerant leak. An HVAC technician can be hired to fix the leak. But it is not recommended to do this if you don’t know about HVAC systems.

Regular maintenance of your system will help you avoid problems like this. Also, you should always keep your AC unit in good condition. And it is recommended that you have the system thoroughly checked at least once a year. Air Care Heating & Cooling in Shawnee, KS, will help maintain your system.
