Hello everyone! I’m new to the forum, and looking forward to sharing my experiences with the forum, as well as looking for some guidance! I have a question about servicing my basement air unit. Is there any way to clean the coils on the unit without removing it? Maybe cut a hole something make a service hatch?? Thanks in advance!

Make and model would help. Most are already incased and just cutting a hole will not let you do a good job cleaning. call a friend who use to own one and he said to you Good Luck. He stated his comes out the bottom of the RV. It was made by coleman who no longer makes them. It has two compressors. As stated its a case inside a case. here is a picture maybe of what you have. https://www.pplmotorhomes.com/parts/rv-appliances/air-conditioner/air-conditioners-coleman-dometic/coleman-mach-2-ton-plus-basement-ac-he-w-heat-pump_69859

The outside Condenser coils you can access from the outside with a Garden Hose. The INSIDE Evap coils are harder to get at. Remove the AC filter under the rear bed and see if you can access the Evap there. Are you asking because you have a cooling problem? Doug

To do the best job the unit should be removed and cleaned and serviced. There are some shops that can do that very well.See my PMJimR

Thanks for the replies, everyone. The unit is working fine, but I’ve had it for several years now, and would like to clean the evaporator coil, as I’m pretty sure it’s getting quite dirty by now. I have a 2005 40 fd model. The inlet is above and behind the bed, and I can’t see where I could get to it easily from there to clean it in place. Guess I’ll have to set aside a couple days to try pulling the unit. I’ve heard they are removed from below, but that would involve even removing the heater ductwork as it passes below the ac unit. I’ve always been told “if it ain’t broke, don’t fix it”, but I know dirty coils can lead to higher compressor pressures and shorter life. I’ll update if / when I get it done. Thanks!
