DAE have a moment where you realized you'd been cleaning condenser coils wrong the whole time?
I was at a customer's house in Mesa and she pointed out I was spraying water straight into the coils instead of pulling the brush down with the fins. Been doing it sideways for 4 yrs. Any of you got a method that actually gets the gunk out without bending fins?
Keep the water pressure low and spray at an angle from the top down, not straight in. Let the brush do the work after the rinse, just pull it with the fins, not against them. Also those coil cleaners in a can actually help break the crud up first so you're not scrubbing dried gunk.
