It depends how old it is most can be regased but about 15 or so years ago they changed refrigerant gases because the old one was killing the ozone if not that old you should have no problems with regasing it just make sure they check for gas leaks first which is a small amount of dye put in the gas so you can see the leak. Hope this helps

Give model & make, and approximately how old. Has anyone checked unit for any possible electrical problem that may be causing this? Is there something obvious that made you feel cooling unit needs recharge? I've seen these run for 10-15 years, so I'm finding it hard to believe that it needs re-charge.

Is it common for a rv rooftop air conditioner to leak water on to the roof? I have a Dometic Duo-Therm unit 579,590,595 series.


All AC units create condensation from the cooling of air (cold/cool air hold less water than warm air), it is worse in areas of humid air like the Midwest for example.

The upper unit doesn't matter ( the actual ac unit on roof ) it's the lower control unit (inside at ceiling) that you need to change to use either ducted or non-ducted system. Any RV dealer can supply that, probably have it on the shelf. Just make sure you write down the model number and serial number, off the bottom of the upper unit, so they can match lower unit to it, for ducted system.

You need to find where the drain is. The water should flow to a drain and not into the unit. Once you get the condensation draining properly you can use a good quality silicone to seat around the unit. You might check at a RV parts place and find a product they recommend for RV roofs. Hope this helps.

its good to put them in, as it will keep dust from building up on the coils, thus reducing cooling.just buy some filter material at any hardware store, coarse, like a sponge, not fine paper stuff.

Coleman tsr rv air conditioner leaks into rv when running


It probably has a clogged condensate drain. Take off the cover on top the RV and check hoses or tubes leaving unit for debris or lint. Often this water is used to help cool the condenser so look for leaves pine needles etc in the pan. There may be a cover you can remove on the evaporator section that will allow you to clean the collection pan and hose or trough. Is it possible the RV is far enough out of level that the condensate can't "run uphill"? Always power off while working on this unit unless you are electric savvy. Good luck!
