When your HVAC system blows warm air instead of cold, it can be frustrating. Here are some common causes and solutions:
Check Thermostat Settings: Ensure the thermostat is set to “cool” and not accidentally switched to “heat.” Also, verify that the fan setting is on “auto” rather than “on” to prevent continuous warm air circulation.
Inspect Air Filters: Dirty or clogged air filters can reduce cooling efficiency, causing warm air. Regularly replace or clean the filters to maintain optimal performance.
Refrigerant Levels: Low refrigerant levels can lead to warm air. If you suspect this issue, consult a professional to diagnose and address any leaks.
