There’s Ice Forming on My Air Conditioning Unit — What’s Wrong?

Your air conditioner is responsible for cooling things down, but you can get too much of a good thing. If you see ice forming on your air conditioning unit, that's not normal. Low refrigerant levels and poor airflow can bring an early winter to your system. An icy air conditioner may look like an easy fix, but simply scraping off the ice can damage your unit and won't fix the larger issue at hand. Fortunately, all’s not lost: The first step is turning off your air conditioner to allow it to defrost.

Why Your AC Is Frozen

Check the condition of your air filter first and replace it if needed. From there, your technician can help you investigate your slippery problem.

Potential Issues

  • ice is forming on the air conditioning unit
  • not reaching temperature set on thermostat

A heat pump works year round to keep a steady temperature in your home. Sometimes they fail due to faulty controls, poor communication between the control board and the system, or an issue with wiring. Like any other part of your system, it can also wear with age. If your heat pump isn’t working properly during the wintertime, especially if it’s not defrosting, this is likely due to a worn, damaged, failed defrost termination switch or defrost control board. It’s time for a replacement.

  • high electricity bills
  • ice is forming on the air conditioning unit
  • not reaching temperature set on thermostat

TXV is short for thermostatic expansion valve. It is the part in your air conditioning system that is responsible for maintaining a steady flow of refrigerant to the evaporator using a sensing bulb — critical to keep you cool. In most cases, the TXV fails because the sensing bulb has lost its charge.
