Why Is Your A/C Freezing Up in the Summer?

Why Is Your A/C Freezing Up in the Summer? Ice build-up in your air conditioning unit in the middle of the heat wave is not a good sign. Let us tell you what causes this scenario and what you can do about it.

#1 Low Refrigerant Level

Refrigerant insufficiency causes ice formation in your A/C unit. When refrigerant leaks out, heat transfer fails and temperature drops. Then, your unit will start to freeze up and damage the other parts of your systems. For this case, the best thing you need to do is call a local HVAC expert in St. Louis, MO, for a dependable solution.

#2 Clogged Coils and Fins

Another cause of ice buildup in your system is clogged coils and fins. They are highly susceptible to dirt, dust, and other debris, which makes it harder for heat to transfer into the coils. Since they are the least noticeable components, they are always deprived of regular maintenance check. You can either clean them by using a spray type coil cleaner or call a licensed technician to get it done professionally.

#3 Malfunctioned Blower Motor

The blower motor is responsible for getting the warm air from your house and then releasing it through the air conditioner. When it starts to malfunction, the air will not flow properly, which can cause the condensation on the coils to get stuck. Consequently, it will be left to freeze, and no air will come out of the vents.

What Should You Do?

As soon as you notice your air conditioning unit freezing up, here’s what you need to do:
  1. Turn your unit off completely. Wait for the ice to melt, or you can use a blow dryer to speed up the process.
  2. Check the condensate drain if it is not blocked and open all registers. Make sure nothing restricts the airflow such as drapes and furniture.
  3. Inspect your air ducts for any bends and disconnections. In case that your ductwork is dirty, you can use a shop vacuum for cleaning.
  4. Replace air filters every three months.
  5. Clean the coils and fins regularly.
  6. Schedule preventative maintenance service.
