3 Common Causes of an AC Freeze Up

AC freeze ups are a common problem, especially during the hot summer months when your unit has to work extra hard to keep your home cool. Figuring out what is causing the freeze up can be quite frustrating sometimes. Today's blog from your favorite Lake of the Ozarks HVAC company discusses some common causes of an AC freeze up.

1. Poor Airflow. 


The most common reason air conditioners freeze up is due to a lack of airflow. The way your AC works is that it pulls in the indoor air and blows it over the evaporator coil. This allows the refrigerant to absorb the heat, therefore cooling the air before it's pushed back out. If anything stops, blocks or restricts that air from flowing over the coil, it gets too cold, causing any condensation or moisture to turn to ice. Airflow issues are often a result of a dirty air filter. During the summer months, it's important that you change your air filter once a month. If you replace your air filter and the problem isn't resolved, you'll want to call a professional for air conditioning repair at the Lake of the Ozarks.

2. Low Refrigerant. 


Another common cause of an AC freeze up is low refrigerant. When your AC unit is low on refrigerant, the system pressure drops and the temperature along with it. The evaporator coil then gets too cold and freezes up. If your unit is experiencing low levels of refrigerant, you most likely have a leak somewhere. This is when you'll want to call in the professionals at Royal Heating and Air. We will find the leak and get you an estimate on the repairs.

3. Dirty Coils.


Your air filter isn't the only part of  your unit that can become dirty. Dirty coils are also a common cause of AC freeze ups. In addition to cooling the air, the evaporator coils also dehumidify it, pulling water out of it. Typically, that water will condense on the coils and then drip off into the pan below. However, if the coils are covered in a layer of dirt, it can prevent the water from absorbing fast enough and then it can freeze. Bi-annual HVAC checkups from your local provider can keep your coils clean and prevent this issue from occurring.
