Cleaning your outdoor air conditioner unit will not take more than an hour, even if you work slow. Of course, you may sweat a lot when cleaning. But every drop of sweat counts as you will save lots of money in operating your air conditioner in the days to come.

Start Your Work From Outside

Turn of Electrical Supply: Before you approach the air conditioning unit, you should turn off the power supply to avoid the possible mishap. Just turning off the thermostat alone is not sufficient, as someone would accidentally turn it on while you are working with the condenser.

Remove branches, nests, leaves and other debris that are surrounding your condenser unit. Create a clearance zone of 2-foot from the condenser unit, and 4-foot of clearance zone above the unit by cutting the tree branches, hanging leaves or any other plantings.

Use high-powered vacuum cleaners to remove the dust and debris settled in the exterior fins.

To have complete access to the fins, you need to unscrew and remove the metal box. You can refer the owner manual to see how to remove the box safely.

You don’t need to get panicked if you find the fins are bent lightly. This is a normal thing, and you can bring them back to the normal shape by using the fin comb tool, which is available in most home improvement shop.
