How old is this unit? In the Duo-Therm Brisk Air Models, they were notorious for a small leak in the capillary tube that runs into the evaporator part of the AC. There are two small tubes that are run together, take the top off of the evaporator coil and pull the lines apart gently. Look for noticeable signs of leaking in the area. If the lines have been looking or look like they have rubbed together for an extended period of time, you need to have someone replace the lines or buy a new air conditioner. I would price both before committing to either one. Hope this helps.

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.
