Your central AC system uses many parts and components that need to be cleaned and serviced each spring by an HVAC technician to make sure it operates at peak efficiency. Though, there are some cleaning tasks you can do yourself to save money. Use this guide for how to clean AC condenser coils to get started.
Condenser Coil Basics
The condenser coil is located in the outdoor unit of your HVAC system. It's job is to release heat energy that was collected by its indoor counterpart: the evaporator coil. This is accomplished by a large fan pulling air across the condenser coil, which instigates heat transfer. The dirtier the condenser coil is, the less efficient heat transfer becomes. This results in higher energy usage.
Step 1: How to Clean AC Condenser Coils
The first step of how to clean AC condenser coils is to shut off the power to the central air system at the thermostat and at the disconnect box located on your home's wall near the outdoor unit.
Step 2: How to Clean AC Condenser Coils
Use a shop vacuum with the brush attachment to remove debris from the fins located on the sides of the outdoor unit. Clear away any weeds and obstructions within two feet of the outdoor unit.
Step 3: How to Clean AC Condenser Coils
Use a fin comb, which you can pick up at a home store or online, to straighten bent fins.
Step 4: How to Clean AC Condenser Coils
Unscrew the screws holding the blower assembly (i.e., the cage guard, fan, and motor) in place, which is located on top of the outdoor unit. Carefully set the blower assembly aside, being mindful of wiring.
Step 5: How to Clean AC Condenser Coils
Spray the condenser coils with a can of coil cleaner. After the coil cleaner has done its job, spray the coil and fins from the inside of the outdoor unit with a garden hose. Reattach the blower assembly and turn power back on.
