What Is A Frozen AC?

A frozen air conditioner is a frustrating phenomenon that can be as confusing as it is costly. Don’t wait to contact a professional team if you see ice on your AC unit. When it comes to avoiding a frozen AC, understanding how your cooling system works is the first step.

Central cooling systems work by circulating refrigerant through the indoor and outdoor units, utilizing blowers and pressure to force the coolant through different states. As the refrigerant travels to your evaporator coil, it expands and cools before moving into your home to condense and remove heat from your space. Read on to learn the three most common reasons for a frozen AC.

Why Your AC Unit Is Frozen

Most commonly, frozen ACs are caused by one of the following:

  • Poor airflow – Clogged or dirty air filters decrease airflow through the system, which can make your unit humid. Moisture can then settle and collect on your coils and freeze.
  • Mechanical problems – When blowers and fans aren’t functioning, air isn’t traveling across your coils and keeping humidity low.
  • Refrigerant leaks – Leaks are an obvious issue, as lowering the refrigerant pressure causes the coolant to expand too much and become too cold. Aside from leaks, refrigerant lines can also kink, which can increase the pressure as well and result in frozen coils.

Since your AC can freeze for so many different reasons, it’s best to reach out to professional technicians for help. Our team can conduct an efficient inspection to pinpoint the cause of your freeze fast. Then we’ll get right to work to bring your unit back into good working order!

What To Do When Your AC Freezes

It’s understandable to wonder can a frozen AC fix itself? After all, the unit is sitting outside under the hot summer sun. So is it possible for a frozen air conditioner to fix itself? The answer is yes and no – depending on why the unit froze in the first place.

If the ice formed because of low airflow, you can try turning off the AC and letting it thaw for a few hours, changing the air filter while it’s thawing and then turning on just the fan to dry the system out for an hour. Sometimes that’s all it takes to get a frozen AC working again.

In the case of damaged parts, worn-out elements or a kinked refrigerant line, you’ll need professional AC services. Our team is here for you, ready to help residents in and around New Orleans, Kenner and Madisonville.

Very professional!

The technician, Rene, was very thorough and informative. He called before he was arriving to let me know when he would be there. It was in the window of time Surgis gave me. I will definitely use them for regular maintenance and future HVAC needs. Very professional!
