Re: Penguin Coil Cleaning

T-Man,
I successfully cleaned the coils in both of our units without too much trouble. I purchased a can of foaming coil cleaner from Home Depot and a plastic nozel for flushing/cleaning RV water heater tanks. Nozel is about 12 inches long and 1/4 dia or smaller. I fixed an inline hose valve to it to control the spray/water volume. I removed the inside and outside covers to expose the coils. I stuffed an old towel in from below to catch any overspray into the coach. Good idea to place another towel or mat under the ac being worked on just in case. Then to the roof with foam cleaner and water hose with nozel attached. I sprayed the foam on exposed coil surfaces and let it set for a few minutes. While waiting I located the drain holes in each end of the drain pan under the coil and flushed the pan and drain holes. It takes only a little spray to rinse the foam away and you must be careful not to overflow the drain pan, so slow going is a must. I used a toothbrush on a few areas then repeated the foam and rinse. The coil and pan were bright and clean so reassembled, sealing (caulk) the metal coil cover. No more "wet dog" odor...just clean fresh air from our units. If your careful and don't overflow the drain pan there is little mess. And during the peak of summer, I remove the interior cover and simply spray the exposed side (dirty side) of the coil to keep it clean, does not require rinsing. That's how I did it...hope it will help you in getting yours clean.
