Wondering why AC freezes up constantly, on a regular basis, or it has never frozen and it has now it decided to “surprise” you, you should not worry. Specialists agree that there are some common causes that trigger these freeze patterns, so experiencing AC freezing is quite common.
Obviously, if your AC is frozen, it is imperative to contact a technician for a consultation.
1. Blocked or Restricted Airflow
One of the biggest problems of modern air conditioners relates to the airflow in your home. The culprit in this case is dirty air filters that prevent the air from moving around. As a result, the cool air stays around the evaporated coil, forming ice and gradually freezing up your system. The best thing you can do to prevent this issue in the first place is to regularly change the air filters.
Once the airflow is restricted, you should stop the AC immediately and wait a few hours until warm air gets inside the device. Use a spray type coil cleaner to melt the ice around the evaporated coils. Change the filters right away and also ensure there are no objects trapped around the evaporator. Of course, you are better off if you call a AC system repair professional.
2. Refrigerant Leaks
The second cause of why AC freezes up is the issue of refrigerant leaks. Whether it’s Freon or any other refrigerant, the operating temperature of the evaporator coils has dropped significantly. This lower temperature leads to increased condensation inside the device and to the forming of ice blockages.
The moment you see that ice is being formed around the evaporator coils, turn off the unit and wait for the ice to melt. Note that this might take up to one week. Instead of waiting so much, it is wiser to call for a trustworthy technician to solve your problem ASAP.
The best solution for a refrigerant leak problem is to call for the HVAC technician, as sealing the leak requires advanced knowledge and professional tools that you probably don’t have.
3. Low Outdoor Temperature
Lastly, the reason why AC freezes up is due to the very low outdoor temperature. If there is less than 0 degrees Fahrenheit outside and you desperately need some extra heat, make sure that your AC is on fan mode. This will ensure that cold air from outside will not come in direct contact with the evaporator coils.
