AC unit freezing up in Oregon City, OR

If you have an AC unit in your home, then you know that it can be a life-saver during the summer months. But what do you do when it freezes up? We will discuss some of the most common causes of AC unit freezing and provide tips on fixing the issue.

1. Check the Air Filter

A dirty air filter is one of the most common causes of an AC unit freezing up. When the air filter is clogged, it restricts airflow and causes the evaporator coils to freeze. If you suspect your AC unit’s freezing problem is due to a dirty air filter, replace it with a new one.

2. Inspect the Evaporator Coils

Another common cause of AC unit freezing is dirty or damaged evaporator coils. If the coils are covered in dust or dirt, they will not be able to absorb heat properly, which can cause them to freeze over. Inspect the coils and clean them off if necessary. You may also need to replace the coils if they are damaged.

3. Check the Refrigerant Level

Low refrigerant levels can also cause the AC unit to freeze up. When the refrigerant level is low, it can cause the evaporator coils to become too cold, which can lead to freezing. You will require a professional to check the refrigerant level and add more if necessary. At Anderson Heating & Cooling, we offer exceptional heating and cooling services for people throughout Oregon City.

4. Adjust the Thermostat

Ensure that your AC unit’s thermostat is set to “Cool” mode and that the fan is set to “Auto.” Incorrect settings can cause the unit to work harder than necessary and may lead to freezing.

5. Turn Off the Unit

If your AC unit keeps freezing up, you may need to turn it off for a while and allow it to thaw out. Once it has thawed, you can turn it back on and see if the problem has been fixed.
