If your air conditioner ventilates hot air, it will be difficult to stay comfortable in your Lexington, KY, home or office this summer. From worn compressors to refrigerant leaks, the AC repair specialists at Stewart Air Conditioning & Heating know there are several contributing factors to this common malfunction.

AC Repair Professionals Explain Why Hot Air Blows From Cooling Equipment

Damaged Compressor 

Air conditioners need refrigerant to produce cold air. To cycle through the system, the gas is converted to liquid. The unit’s compressor helps complete the process. When it’s broken, warm air is created instead. 

Cracks in the Ductwork

An intricate network of ducts channel cold air from the AC unit location to the rest of the property. If the ducts are cracked, warm air will seep in. Cold air will be a few degrees higher than where the system is set.

Outdoor Obstructions

If an air conditioner is installed outdoors, the area should be clear of shrubs and tree branches. Overgrown vegetation and falling leaves and twigs can clog air vents, causing the system to overheat. When this happens, cooling equipment produces warm air and drains energy to perform basic functions.  

Leaking Refrigerant 

To produce air, an air conditioner just needs to be turned on. Refrigerant is needed for the air to be cold. When too much escapes from damaged equipment, the air won’t get as cold as it could. Frosted evaporator coils are a telltale sign of refrigerant leaks. AC repair technicians also have specialized equipment to test for damage.
