Air Conditioning Service in Mansfield, TX – Evaporator Coil Freezing Over

One of the most common issues that can happen with an air conditioner during the summer is a frozen evaporator coil. There are many problems that can happen that will increase the likelihood of an evaporator coil freezing over. The following list goes into detail with what you should inspect with your air conditioning unit before you contact a professional air conditioning service company for assistance.

If your evaporator coil has frozen over you should immediately turn off the air conditioning unit. If you continue to operate the system it is possible that the compressor may become damaged. If you need assistance then give Minuteman Heating and Air a call and schedule an appointment for service.


Reasons Why an Evaporator Coil May Freeze


  • If the air flow is restricted around the evaporator coil then the temperature of the coil will eventually drop below freezing point. Whenever this happens the surrounding humidity and condensation with begin to freeze over.


  • Frequently change the air filter in the air conditioning system to ensure it stays clean. If this is not done frequently then the air filter could be the very reason why the coils are freezing up. Replacing the air filter will typically resolve this.


  • If possible, inspect the evaporator coils from the side of the intake to see if they are clean. If they appear to be corroded then they will need to be professionally cleaned. This is best left with a professional service company, such as, Minuteman Heating and Air.


If you decide to attempt to clean the coils yourself then you will need the proper cleaning materials and tools at hand. It is not recommended that you do this yourself but you can find many how to guides on the web explaining how to do so.


  • Have a look at the intake grilles to make sure there is no blockage there. If the intake grilles are blocked then remove the object that is blocking the grille. Once removed, allow the evaporator coils to thaw completely out before you turn the system back on to see if this resolves the problem.


  • Oftentimes, there might be to many registers that have been closed or blocked by furniture. Whenever this is the case it causes the air to be circulated into only one part of the home which can possibly cause the coils to freeze up. Generally, you do not want to have more than 10 or 20% of the registers closed off in your home. More than this and you risk the coils freezing up.


  • Inspect the blower motor for the AC unit. If you happen to find it is not operating as intended or not running at all then this is most definitely the cause behind the coils freezing up and it will need to be replaced.


  • If the temperature in the home has reached the setting at the thermostat then the outdoor unit should shut off as intended. However, if it has not shut off and is continually running then there is most likely a problem with a contactor. Contact a professional AC service company, such as, Minuteman Heating and Air to service the outdoor unit and rectify the problem.


  • Finally, there might be a problem with the refrigerant in the system, it is possible there is a leak and the system will need to be re-charged. However, if there is a leak, then the leak will need to be found and fixed and / or replaced.Otherwise, the leak will continue discharging the refrigerant over time and it will need to be tapped off frequently.
