7 Reasons Why Your AC Pipes are Frozen – And How to Fix It

An air conditioning unit is important, especially in areas with warm weather. You will be using that a lot during the summer season. That is why you should keep a regular maintenance schedule for your AC units, such as cleaning and other necessary repairs. You might also have to hire a professional plumber for any AC concerns that you should be fixed ASAP. 

Unfortunately, your AC will need some repairing at some point. Airconditioning unit problems can be due to several reasons. One of the most common AC issues is a frozen AC line. Please make sure not to leave it ignored, or it could lead to the worst consequences and more expensive repairs. 

Common reasons why AC pipes are frozen 

Do you have a frozen AC pipeline? Don’t worry; it can be solved, and you can still save your AC for another day. First, you should turn off your air conditioning unit immediately and set it to Fan mode. Then check out this post to determine what causes a frozen AC pipe. 

One of the most common reasons your AC pipes are frozen is that the evaporator coils are too cold. The evaporator coil contains a refrigerant that makes the air cool when you turn on the AC. If it is working properly, it absorbs the heat from the air and makes the air cool. But if it has a problem, it could be because the evaporator coil absorbs less heat and cause the formation of ice on the coils. 

Tell-tale signs that your AC becomes frozen are: 

  • Low refrigerant levels 
  • Collapsed air ducts 
  • Malfunctioning blower fan 
  • Clogged air filters
  • Blocked AC vents
  • Dirty coils 
  • Refrigerant leaks coming from the evaporator coil 

How to fix frozen AC pipes

You can try fixing the pipes yourself or hire a professional handyman to help you repair your malfunctioning air conditioning unit. Some of these solutions can solve your AC problems temporarily. But for serious cases, it would be best to contact a professional maintenance specialist to fix your AC. Here are ways you can fix your air conditioner: 

Turn off your AC and switch to Fan mode. 

Doing this will give your AC time to cool off and keep warm air circulating through the AC system. Wait for about 3-4 hours before you restart your air conditioner. If it freezes when you restart it, turn off the AC and contact an aircon technician immediately. 

Check the air filter. 

Your dirty air filters may also cause a frozen AC system. A clogged air filter inhibits airflow that could affect the AC function. If it’s dirty, check your filter and clean it as needed. You can also check blocked or closed return/supply vents if you think that is causing the freezing AC pipes. 

Contact a professional. 

A frozen AC pipe could be more serious issues such as a refrigerant leak, malfunctioning blower motor, or a collapsed air duct. Fixing this means you should seek help from a professional plumber in Franklin, TN, and have it done once and for all.
