Frozen AC Lines

Frozen AC Lines

by Privette Pure Comfort, Wednesday, July 5, 2017 12:57 PM

It’s a hot 90 degrees out, but your air conditioning unit’s refrigerant line is frozen solid. This may seem crazy but it happens.

Here's what you should do as soon as you notice the problem:

Turn off your AC unit and turn the fan setting to “On.” This will help unfreeze the evaporator coil and save your compressor from over working. Now, lets take a look at what causes this to happen in the first place.

What causes the evaporator coil (and refrigerant lines) to freeze up

  • Low airflow

  • Low amounts of refrigerant

Note that low air flow might be something that you can fix without calling a technician to help.

Be sure to check for:

  • Clogged/ Dirty Air Filters

  • Closed supply air vents

  • Blocked return vents

As for the other cause of frozen lines, you will need to call a service technician for assistance.

A technician will check your system for:

  • Refrigerant leaks

  • Malfunctioning indoor blowers

  • Dirty evaporator coils

In summary

Before you call a technician for help, make sure that all of the supply vents are open in your home and check that you are using a clean filter. If the problem persists, call Privette Heating and Air and we will take care of it!
