Common causes include a dirty filter, iced outdoor coil, low refrigerant, wrong thermostat mode, blocked vents, or a bad reversing valve or capacitor. We diagnose issues on site in Denver, Aurora, and nearby.
- Set thermostat to Cool and Auto.
- Replace or clean the filter.
- If the outdoor unit is iced, turn system off and fan on.
- Clear 2 ft around the outdoor unit.
- Check breakers and open all vents.
If cooling still lags, ask about our $69 Repair Assessment or $259 Tune-Up.
