It can be frustrating when you walk into your home on a hot day only to realize that warm air is coming from the vents. There could be several reasons why your AC blows warm air in your New Braunfels, TX home. Here are a few of the possible causes of an air conditioner that blows warm air.
1. Low Refrigerant Levels
Air conditioning units effectively turn hot air into cold air when the refrigerant levels are sufficient. When the refrigerant levels are low, the freon expansion isn’t sufficient, meaning the cooling coil doesn’t adequately cool. You might realize that the air becomes warmer the longer you run the air conditioner.
2. Outside Unit Loses Power
If the outdoor unit loses power and the indoor unit doesn’t, your AC will blow warm air. It could happen because of power resulting from a tripped circuit breaker. You’ll need professional assistance to check the fuse panel and circuit breaker and fix the issue.
3. Faulty Compressor
The air conditioning compressor plays a vital role in compressing the Freon for it to expand and cool down the cooling coils fully. When the compressor is faulty, it fails to compress the Freon fully; thus, the expansions are insufficient, failing to cool the cooling coils. An experienced AC repair technician can inspect the faulty compressor and fix or replace it.
4. Dirty Air Filters
Air filters trap contaminants and particles in the air, preventing them from circulating indoors. Dirty air filters restrict airflow and prevent cool air from circulating throughout your home, forcing the AC to overwork and causing other issues. It’s best to change your air filters every 60 days to prevent clogging that ultimately forces the AC to blow warm air.
