Written by Comfort Solutions HVAC on . Posted in .

Have you found that your AC lines have frost or ice around them in the middle of summer? This is worrisome as your unit will not cool the way it should. It may even stop working completely. However, the problem is not uncommon and can affect any window unit or central air conditioner. Correctly identifying the main reason for the malfunction will help fix it once and for all. 

Common Reasons For Frozen AC Lines 

Almost every day, we have customers calling about cooling units with freezing lines. Here are some typical causes:

  • Low amounts of refrigerant
  • Leaking refrigerant 
  • Dirty filters
  • Clogged ducts
  • Blocked or closed vent covers
  • Closed dampers
  • Dirty evaporator coils
  • Malfunctioning or damaged indoor blower fan

What to do when your AC is freezing up

Turn off the unit immediately. Keeping it on is likely to worsen the problem and damage your expensive cooling unit in the process. There are numerous DIY solutions you will find on the Internet, however, it is not advisable to tamper with your complex air conditioner. Without proper training and the right tools, you could injure yourself and wreck your AC.
