Why Do Air Conditioner Condensers Freeze?

Why Do Air Conditioner Condensers Freeze

We rely on our AC systems to help us control the climate in our homes. When there is a problem with your air conditioner you can be left exposed to uncomfortable high heats and humidity. Our HVAC professionals work with home and business owners to prevent and correct problems such as your AC freezing.

Top 5 Reasons Air Conditioners Freeze

Have you experienced an issue with your air conditioning unit freezing? Working with one of the experienced HVAC technicians at Autumn Air can help you to quickly diagnose and correct any problem you are having with your frozen AC unit. Listed below are some of the main reasons your AC may be freezing:

Low Refrigerant Levels

If your air conditioner is low on refrigerant, it can cause the evaporator coil to freeze up. When this happens your air conditioner’s condenser may freeze as well. This happens because low refrigerant levels can cause the pressure in the system to drop, which can lower the temperature of the evaporator coil. If you have noticed a change in your air conditioner’s performance, reach out to the team at Autumn Air in Spring, TX.

Dirty Air Filter

Dirty air filters will restrict the airflow passing through your HVAC system. This can cause the evaporator coil to become too cold and eventually freeze up. When this happens, the condenser can also freeze because it’s not receiving the warm air it needs to keep the refrigerant at the right temperature. Make sure you are changing your air filters once every 30-90 days, depending on the filter you have.

Blocked Airflow

If there is something blocking the airflow over the evaporator coil, such as furniture or other objects, it can cause the coil to freeze up, which can also lead to your air conditioner’s condenser to freeze. Reach out to our team to schedule a repair service for your air conditioner if you have continued issue with your HVAC system.

Malfunctioning Thermostat

If your thermostat is not functioning correctly, it can cause the air conditioner to run for longer than necessary, which can cause the evaporator coil to become too cold and freeze up. Additionally, your thermostat may have a sensor issue that makes it unable to determine the temperature in your space. This can lead to an AC overrunning or not turning on at all.

Fan problems

If there is a problem with the fan that moves air over the evaporator coil or the condenser coil, it can cause the coils to freeze up.

In general, any issue that causes the evaporator coil to become too cold can lead to a frozen condenser. It’s essential to address any freezing issues as soon as possible to prevent damage to your air conditioning system. Reach out to the HVAC team at Autumn Air to get the highest quality HVAC services for your home or business. We will work with you to get a fast diagnosis to the problem and then let you know what solutions are available.

How Often Should My AC Be Serviced?
