Quick DIY Checks Before Calling
Check Your Thermostat
Ensure it's set to "cool" mode and the temperature is set lower than the current room temperature. Replace batteries if needed.
Inspect Air Filter
A dirty filter can cause your system to work harder and blow warm air. Replace it if it looks gray or clogged with debris.
Check Circuit Breakers
Look for tripped breakers in your electrical panel. Reset any that have switched off, which might restore power to your outdoor unit.
Clear Outdoor Unit
Remove any debris, leaves, or vegetation around your outdoor condenser unit to ensure proper airflow and heat dissipation.
