A frozen air conditioner is more than just an inconvenience—it’s a sign that something isn’t working properly within your HVAC system. If left unresolved, it could lead to costly AC repairs or even require an AC replacement. Fortunately, some issues can be addressed with basic troubleshooting. Here’s how to tackle a frozen air conditioner and determine if you need professional assistance.
Step 1: Turn Off the AC and Allow It to Thaw
Before attempting any repairs, turn off your air conditioner and let it thaw completely. This might take several hours, depending on the extent of the ice buildup. Continuing to run a frozen AC can cause further damage to the unit.
Step 2: Check and Replace the Air Filter
One of the most common causes of a frozen air conditioner is a dirty or clogged air filter. When the air filter is blocked, it restricts airflow, causing the evaporator coil to freeze. After the unit has thawed, replace the air filter with a new one. If you’re unsure how to do this, or if the problem persists, consider scheduling an AC maintenance service in Westport, Dartmouth, Fall River, New Bedford, Fairhaven, or Marion.
Step 3: Inspect the Refrigerant Levels
Low refrigerant levels can also cause your air conditioner to freeze. This is often due to a refrigerant leak, which can be hazardous and requires a professional HVAC technician to repair. If you suspect a refrigerant issue, contact Family Heating and Cooling for an AC repair service.
Step 4: Check for Blocked or Closed Vents
Ensure that all the vents in your home are open and unobstructed. Blocked vents can restrict airflow, leading to uneven cooling and potential freezing of the air conditioner. If you notice any inconsistencies in airflow, it may be time to have your ductwork inspected and cleaned by a professional.
Step 5: Examine the Thermostat Settings
Sometimes, the problem might be as simple as incorrect thermostat settings. Make sure your thermostat is set to “Auto” rather than “On.” When set to “On,” the fan runs continuously, even when the air isn’t being cooled, which can lead to freezing.
