It’s probably weird to see a frozen A/C coil when it is 95 degrees outside. Sadly, when your A/C coil freezes it’s a huge sign that something isn’t right with your A/C and ignoring the issue can make your compressor burn out.

Signs That You Have a Frozen AC Coil

If you believe there are issues with your A/C, you might want to see if your A/C coils are freezing up. You can also:

  • Check around your air handler for moisture
  • Look for ice around the outdoor refrigerant line
  • A full or overflowing condensate drain pan
  • Clogged drainpipe

Open up your air handler and inspect A/C coil for condensation or frost. If your HVAC unit shows any of the above symptoms, it is imperative that you address the problem ASAP. A frozen A/C is never a good sign.

If you see that you have frozen A/C coils, the first thing you should do is turn off your unit by the breaker box. To realize your situation, let’s look at a couple of causes and the solutions.

Dirty A/C Coils

If dirt and dust collect around the AC coils, which pass on refrigerant to the heat pump, it will put more strain on your system to condition the air, putting your AC coil at the risk of freezing. The coils need to be cleaned regularly for proper heat absorption to occur; otherwise, the coils might freeze over.

This is another reason why it is critical to schedule yearly professional maintenance with a Rochester heating and cooling company. Your unit will be cleaned and examined to avert possible issues like this one.

Refrigerant Problems

Since refrigerant runs in a closed system, you probably don’t have to replace your refrigerant unless there is a leak someplace in the unit. Although leaks due to regular wear and tear are common, they sometimes go undetected for extended lengths of time. Running your HVAC unit with low refrigerant levels puts a needless strain on your unit and can make ice form on your AC coils.

Your best bet is to call in a professional that specializes in air conditioning in Rochester to assess your unit for leaks as well as restore your refrigerant levels. If you don’t take care of the underlying leak, you will have the same issue again pretty soon.​
