A well-maintained air conditioner will run more efficiently, saving you money on utility bills.
Step 7: Restore power to the system. With the air conditioner unit cleaned and a new filter in place, the system is ready to be used again. Turn power back on at the electrical panel and enjoy the efficient operation of the tuned-up air conditioning system. Turn the switch back on at the panel.
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.
