Whether you schedule regular air conditioner maintenance or prefer to clean it yourself, it’s important to maintain your system to prevent costly repairs. That’s why we’ve put together a step-by-step guide on how to clean your air conditioner, starting with the condenser.

Cleaning the Outdoor Condensing Unit

How to Clean a Central Air Conditioner Without a ProfessionalUse the Breaker Box to Deactivate the Air Conditioner

Prior to cleaning your AC unit, it’s important to deactivate the power. To turn the air conditioner off, locate the breaker box connected to the system. This is a square box that is connected to the wall on the exterior of your house. Open the circuit breaker box and flip the button to the off position. Turning off the air conditioner is extremely important and allows you to properly disassemble and clean without harming the unit or yourself.

Use a Wet or Dry Vacuum to Remove Dirt From the Condenser Fins

The condenser fins are situated on the exterior of the outdoor condensing unit of the central air conditioning system. Condenser fins are engineered to push excess heat away from the air conditioner. To clean the condenser fins, carefully move the nozzle of a wet or dry vacuum over them. Wet or dry vacuums can typically be found at the hardware store and online. This clears any dirt and debris on the fins that may hinder the condenser to draw in air effectively.

How to Clean a Central Air Conditioner Without a ProfessionalStraighten the Condenser Fins

Once you have cleaned the condenser fins on your air conditioner, we recommend straightening any noticeable bent or twisted fins. You can do this by using a kitchen utensil such as a knife to gently bend the fins back into position. Try to be steady and gentle when straightening the fins to avoid breaking or damaging them.

Cleaning the Fan in the Compressor

Once you are finished cleaning the condenser of the central air conditioner unit, you will be required to remove dirt and debris from the fan. You will need to first remove the fan from the air conditioner compressor. First, use a screwdriver to remove the wiring from the front of the fan. Next, identify the fan near the top of the compressor and remove it.

Use a screwdriver to remove the grate panel. Next, unscrew and remove the fan. Please note that the fan motor does have fragile wires that are connected to the compressor. This means you may not be able to completely remove the fan from the central air conditioning system. However, you should be able to lift the fan from the compressor to remove dirt, debris, and other objects.

Use a Water Hose to Sanitize the Fan Blades

Use an outdoor hose to wash away dirt, rubble, twigs, leaves, and other contaminants from the fan blades. If your garden hose is unable to remove dirt and debris from the blades, use a paper towel and sanitation spray to sanitize the fan. Once you’ve wiped the blades, spray water through the compressor’s fins from inside of the unit to ensure you impede any blockage that may occur from debris.

Put Compressor Back Together

Once you’ve vacuumed the condenser fins and sanitized the fan glades, you may put the compressor together. Do this by placing the fan back on top of the compressor, and re-screwing it to the metal frame. Next, insert the screws for the grate panel that goes on top of the fan. Once the compressor is assembled, you may activate the power to your central air conditioning system.
