A well-maintained air conditioner will run more efficiently, saving you money on utility bills.
Step 2: Clean the area around the unit. Central air conditioning systems have units outside the house that work with components inside the house to cool the air. Start by cleaning away any leaves, dirt or debris surrounding the unit.
Use a rake to clean the area around the unit.
Make sure that electrical power is disconnected from the air conditioner unit before servicing. Window units should be unplugged; central air units should be turned off at the fuse box. For specifics about servicing your specific air conditioner, always refer to the service manual for instructions and safety warnings.
