When your AC is working well, it can feel like a blessing on a hot summer day. Your AC unit keeps your home cool through balancing airflow, temperature, and pressure. If one of these requirements is out of balance, it can result in less-efficient cooling and, in more dire situations, your AC freezing up. Consider the following tips for handling your AC unit freezing up in summer.

Open Air Vents

One of the more common reasons for your AC unit freezing up in summer is a lack of airflow. A lack of warm airflow causes the condensation to freeze. Once it starts freezing, it soon develops into a block of ice. To ensure good airflow, make sure that all of the air vents are open and unobstructed.

Unchanged Air Filters

A clogged air filter can restrict airflow to the point that it causes the AC unit to freeze up in summer. After you have checked all the air vents, check the air filter to see if it is dirty and needs to be changed. A clogged air filter will also make your AC work harder, which uses more energy. So, staying on top of filter changes can save you money too!

Low Refrigerant Level

When the refrigerant level is too low in your AC unit, it throws its refined control of airflow, temperature, and refrigerant pressure out of balance. This can be the cause of your AC unit freezing up in summer. Contact your HVAC technician to inspect your AC to see if a low refrigerant level is the problem. Low refrigerant is also an indicator that it may be time to replace your AC unit.

Blower Motor Problems

The blower motor spins the fan that pulls and pushes airflow through the air ducts and your home. If the blower motor is malfunctioning, it can be the source of the AC unit freezing up in summer. Your AC tech should take a look at the blower motor as well.
