The compressor is the heart of the unit and the compressor is responsible for circulating the refrigerant throughout the entire system. When this breaks down, the vents will only blow warm. Although age is the most obvious culprit for compressor failures, the most important component can also fail because of faulty parts and contamination.

Clogged Air Filters
