An air conditioner that runs constantly without lowering your indoor temperature is typically caused by a clogged air filter, dirty condenser coils, a refrigerant leak, or a failing compressor. In the humid Greenville, SC climate, these common issues force your system to work double-time without producing cool air.
4 Common Reasons Your AC Isn’t Cooling:
– Clogged Air Filter: A dusty filter blocks airflow completely. This suffocates your system and can cause the indoor evaporator coils to freeze over into a block of ice.
– Dirty Outdoor Condenser Unit: Your outdoor unit releases heat collected from inside. If it is covered in dirt, grass clippings, or leaves, it cannot release heat, leaving your house warm.
– Low Refrigerant Levels: Refrigerant is the chemical fluid that cools your air. If there is a leak in your copper lines, the system will blow warm or lukewarm air continuously.
– Failing Compressor: The compressor is the heart of your air conditioner. If it wears out or loses power, your system will blow air through the vents, but it will never get cold.
When to Call a Local Pro in Greenville, SC
If changing your air filter and cleaning your outdoor unit doesn’t fix the problem, you likely have a refrigerant leak or mechanical failure. Running a malfunctioning AC continuously can burn out your motor and lead to expensive repairs.
