Step-By-Step Guide to Servicing an Air Conditioning Unit
1. Turn Off the Power
Before starting, switch off the power to ensure safety while working on your AC unit.
2. Clean or Replace Air Filters
Remove and clean the filters if they’re reusable, or replace them if they’re disposable. Dirty filters reduce efficiency and airflow.
3. Inspect the Evaporator and Condenser Coils
Gently clean the coils with a soft brush or coil cleaner to remove dust and debris that can impede performance.
4. Check the Drain Line
Flush the drain line with water or use a vacuum to clear any blockages. This prevents leaks and water damage.
5. Test the Thermostat
Ensure the thermostat is functioning correctly by checking the temperature settings and responsiveness.
