Basic Clean for Outside Unit

1. Disconnect the unit from all power sources

Find the system "Isolation Switch", ususally located near the oudside unit and switch to the OFF position. If "Isolation Switch" cannot be located, head to the "Circuit Board/Meter Box" and find the "Switch/Circuit Breaker" labeled Air Conditioning or A/C and switch to the OFF position. 

2. Clean off loose debris

Use the hose spray to clean off loose debris (grass, leaves, etc) on the outside unit.

Spray the outside unit with the coil cleaner.

Wait 10-15 minutes as the cleaner foams and bonds with the dirt on the coils.

Rinse the coil cleaner off with the hose.

Do this at least once a year, preferably during spring.
