Air Conditioning Service: Frozen AC Unit

October 1, 2013 | Blog

Mission Air Conditioning was called out to perform AC service at a home just outside of Houston’s Heights in Oak Forest. The HVAC System was a two-year-old Goodman needing repair. It turns out that the unit was frozen, causing it to break down. Let’s take a look at the diagnosis and repair process for a frozen unit.

Diagnosing the Issue

When a technician comes to your home for AC repair, they’ll ask you what you’ve found wrong with the unit. These symptoms can help them narrow down the possible problems before even looking at your system. For this visit, the frozen AC displayed the following symptoms:

  • Home not cooling adequately
  • Low airflow
  • Ice on the suction line in the outdoor unit
  • Low Refrigerant


Frozen Suction Line

Repairing the Problem

Typically, a situation like this will result in either a minor repair to patch the refrigerant leak and correct the charge or replacing the coil under manufacturer warranty due to the age of the unit. Most of the time, the manufacturer will cover the cost of the part but not the cost of labor. While the repair won’t be free, customers in this situation receive a free item from the manufacturer to help with the cost.

A Temporary Fix

If your AC goes out, do a quick check for ice, which will look a bit like snow, on the outdoor unit. If you find ice, turn the system off to thaw out. This should take about two hours. Once the system is thawed and dry, turn it back on for some temporary cooling. While this will hold you over until a technician can take a closer look, it’s not a permanent fix, especially if you have low refrigerant levels.

If your AC freezes, the experts at Mission AC are here to help. Contact us today and start a service request, and we’ll come to your home and repair the problem as fast as possible.
