Your AC blowing hot air can be caused by several common issues:
- The thermostat might be accidentally set to "heat" mode instead of "cool."
- Dirty air filters or evaporator coils can restrict airflow and prevent proper cooling.
- The outside AC unit's condenser coils may be dirty or blocked, reducing heat release.
- The system could be low on refrigerant (Freon) due to leaks, which is essential for cooling.
- Electrical problems like a faulty capacitor or tripped breaker may prevent the compressor from running properly.
- Other issues include clogged drain lines, frozen evaporator coils, damaged compressors, or disconnected ducts.
Checking these factors and maintaining the unit regularly can often solve the problem, but refrigerant leaks and mechanical issues usually require professional repair. Start by verifying thermostat settings, cleaning or replacing air filters, and ensuring the outdoor unit is free of debris. If the problem persists, consider calling a technician for a thorough diagnosis and repair.
