How To Clean Camper Ac Coils

Never cleaned mine yet, need to do before long.

Let set a few minutes and then rinse off with a spray nozzle on the hose. Rinse the roof area off till the water is clear. You don't need to use any stronger chemicals strong then those.

And this must be done from on the roof after removing the A/C cover and then the evaporator cover. Should be done annually if used in humid environments.

Yes IMO that is the best way ... 1. This is the cover over the Evap coil that has to be removed once the shroud is off. 2. Is a pic of the Evap coil once the cover was off. You can see the link/dirt on the top inch or two of the coil and the white dots are styrofoam probably when I installed some extra vents. This is after 3 years of use and probably right around 150days use. Even when we don't need the A/C in the winter we often keep the A/C fan on low to redistribute the air thru the trailer a little better. The white thing at the bottom is the Evap drain tray that collects any condensate and allows it to drain out into the lower A/C shroud. 3. This is a pic of the coil after I cleaned it and I used an old paint brush and tooth brush to clean it. 4. This is pic of one of the condestate drains and it's a fairly high U-channel that runs directly into the drain pan. It simply drains out in that opening in the lower A/C shroud and the onto the roof. This one was on the passenger side of the A/C and under an electrical box. 5. These next two are pics of the drain on the other side of the A/C and the opening it drains into. In the second picture you can see better how this drain connects to the A/C Evap drain pan. Debris can get wedged in between the roof and opening that the drain is over, but that is easily cleaned with a flat ruler run under the A/C shroud and there are also several other openings where the condensate could drain out, but the one in these pics are the main one. Hope this helps someone at least with a Durotherm BriskAir A/C. Larry 2001 standard box 7.3L E-350 PSD Van with 4.10 rear and 2007 Holiday Rambler Aluma-Lite 8306S Been RV'ing since 1974.

"A tip though- be very careful in choosing a product to use- a lot of commercial coil cleaners such as would be found in home center type stores can be pretty strong- not something I would like to run over the outside of my RV, so I only use Enviro-Chem coil cleaner, specifically made for RV use." I have a bottle of condenser cleaner. Neat thing about it is that it foams and the expansion forces the dirt/dust loose. But based on Chris' note, I sprayed ours with Awesome (could have been 409, SprayNine, etc.) and hosed it after that. He cautions us to be careful not to get rinse water down inside the coach, so only flow water over the coils and let the drains get rid of it. Me... ToolTime, MorePower Me... I found at least on our Coleman Mach, I could deflect water with a high tech tool (expired FL license tag) and was able to hose the coil pretty hard without water falling into the coach. With the Mach we had, open, I could see down into the coach with the metal evap cover removed. If God's Your Co-Pilot Move Over, jd 2003 Jayco Escapade 31A on 2002 Ford E450 V10 4R100 218" WB

The only issue I have with that link to Chris's method is that for most A/Cs, just a soft bristle brush like the paint brush I used is all that is needed. If you were to get all that lint in my pics wet it would be a bear to remove and with my paint brush it just flaked off. Now if you are cleaning a 20 or more old AC then an actual cleaner might help.
