Summer might not seem like a time to worry about having a frozen HVAC system, but despite the heat, it’s possible for this to happen, which puts your Indianapolis home at risk of being without air conditioning. Find out more about how to prevent an HVAC freezing up in summer.

Change the Air Filters

HVAC systems can freeze up due to poor airflow. Having a dirty air filter in your HVAC system can interfere with the airflow, which can cause the evaporator coil to become frozen. You should check your air filter to see if it’s dirty, especially if you haven’t changed it in a long time. Put in a new air filter to ensure proper airflow and remember to replace it every few months. Keep in mind that you might have to change it more if you have pets, since dander and hair can clog air filters up quickly.

Check for Clogs in the Condensate Drain Line

Blockages in your HVAC system’s condensate drain line can put the evaporator coil at risk of freezing. Moisture or condensation from the air should be going to the drip tray and leaving through a drainage system. A clogged condensate drain line will need to be repaired to prevent your HVAC freezing up in summer. You can either unclog it with a wet/dry shop vacuum or have an HVAC technician fix it for you.

Schedule an Inspection for Refrigerant Leaks

HVAC technicians can inspect your HVAC system and let you know if there is a refrigerant leak. If a leak is occurring, your HVAC system ends up with low refrigerant levels. This can cause a pressure drop that can result in frozen evaporator coils and your HVAC freezing up in summer. If you have a refrigerant leak, HVAC technicians can repair it, which helps prevent you from having an HVAC freezing up in summer.
