You need to split the condenser coils to clean them all thoroughly. It’s a labor-intensive process, and you need to make sure you can properly support the coils as you peel them away to keep them from sagging and becoming damaged. (Jeff uses cribbing for support.) As with all condenser cleanings, techs must take proper care not to bend or damage the fins as well.

It’s best to start off by blowing down the coil to get the largest soil off. Then, you can spray the coil from the inside out to give it a thorough cleaning and work from top to bottom.
