A working air conditioner will absorb heat from inside the house, transport it away, and vent it outdoors. If it cannot do that efficiently, the heat can build up until the AC unit overheats. This can lead to breakdowns that shorten the life of your HVAC system. To help you prevent overheating, Wilson Heating & Cooling, an experienced HVAC contractor in Lexington, SC, explains below how to maintain your AC unit and avoid the need for air conditioner repair.

How to Keep Your Air Conditioner from Overheating

1. Change Filters Regularly

Your air conditioner’s filter cleans the air of dust, pollen, and other contaminants, and over time it can become dirty enough that airflow is restricted. When this happens, the AC unit must work harder than usual to push air through the filter, risking overheating. To avoid this, replace the filter every 60 to 90 days—or more frequently if you are a smoker or have pets.

2. Check Refrigerant

If the refrigerant lines have leaked fluid, heat transfer is disrupted, putting the unit at risk of overheating and requiring expensive air conditioner repair. To prevent this from happening, have an HVAC contractor inspect your system annually for leaks.

3. Clear Debris From Outdoor Unit

Heat from indoors is transported via ducts to the outdoor condenser unit, where a fan blows the warm air outside through a vent. If the vent is clogged with debris or blocked by boxes, lawn furniture, or other objects, the hot air cannot escape, and the unit could overheat. Always keep the vent cleared of debris and keep foreign objects at least a few feet away from the condenser unit.

The steps outlined above should help you keep your AC from overheating.
