Before temperatures begin to soar during the summer months, now is a good time to give your air conditioning condenser a quick cleaning to ensure that it’s working at peak efficiency. The condenser is the unit that sits outside of the house and is responsible for cooling the air that is blown through the house.
Begin by making sure that there is no tall grass or weeds growing around the condenser unit. Rake up any leaves or grass trimmings that have collected around the base of the unit.
Shut off the power to the condenser. There should be a box on the house by the unit that has either breaker-type switches or a fuse block that you pull out to shut off the power. If you are unsure, shut off the power to the unit at the main breaker panel.
Rinse the coils with water from a garden hose. Be careful not to blast it with high pressure water, as the metal fins are delicate and are easily bent. The goal is to rinse away dirt, pet hair, leaves, or any other debris that has accumulated.
Check your owner’s manual to see if you need to lubricate the fan motor. Some units have enclosed bearings and don’t require this step, but some have a small port to add oil. Only use the proper oil that is recommended and NEVER use WD-40.
Turn the power back on and verify that it is cooling by switching on the air conditioner inside the house. Make sure that your air filter is clean, and change it if needed.
This simple bit of home maintenance can save you money throughout the summer months.
