As the term suggests, a frozen air conditioner refers to a cooling system so lacking in proper airflow that ice has collected on the machinery. If poor airflow prevents air from entering the unit, you may notice ice forming inside your system. As shocking as it seems, summertime is the time of year that many homeowners discover their AC has frozen.

Frozen air conditioners are a common repair request, and we want to help you achieve the airflow you need inside your home. We’ve compiled a guide to help you understand why your unit is frozen and how you can combat the problem.
Causes Of A Frozen Air Conditioner
Your cooling system doesn’t form ice randomly. Different factors can affect the unit’s airflow, causing the coils to freeze. Knowing what causes a frozen AC will help you detect the warning signs, preventing this issue in the future.
Dirty Air Filters
Your air filter is responsible for catching airborne particles that can compromise your system. However, if the device isn’t replaced every two to three months, debris will build up along your filter. Not only can heavy buildup negatively impact your indoor air quality, but it will also prevent air from adequately circulating throughout your AC.
Refrigerant is a substance used to cool air before it reaches your home. Your air conditioner needs this liquid to effectively operate. However, if the refrigerant is leaking, it can cause pressure to drop inside your unit. Low pressure will cause the temperature to fall in the evaporator coil, leading to freezing temperatures and ice formation.
Blocked Condensate Line
Indianapolis is no stranger to humidity. Thanks to your air conditioner, the inside of your home will never feel as muggy as it does outside! The moisture in your indoor air is transferred to your AC unit’s condensate drip tray. If the condensate line forms a clog, it can cause water to become trapped in your system. The low temperatures can cause this water to freeze, taking a toll on your unit.
How To Thaw Your Air Conditioner
A frozen air conditioner is a cruel form of irony. There are a few steps you can take to unfreeze the machinery. Defrosting the unit can take up to a day to complete, but the following steps explain how you can accomplish this task:
- Turn the thermostat off.
- Change the fan setting from “auto” to “on.”
- Allow the fan to thaw the system.
- Start the unit after the ice has melted.
It’s best to contact a professional if the problem persists after thawing your unit. If your cooling system freezes, our technicians can solve the problem with a simple repair service.
