I've been through 3 Dometic air conditioners in 5 years. My son's Coleman is freezing ice on the evaporator coil--sure sign of low Freon. It's 3 years old and the freeze sensor is in place. We both run our ACs all summer long set to a high temperature to control moisture and keep cans from exploding in the heat. I did have a Dometic that lasted from 2005 to 2013, also run in the summer. Is Coleman now getting crappy Chinese evaporators like Dometic? So, how long should an RV AC last?

My Dometic briskair is 16. I would say it's had average use, not like being in Las Vegas in July.

The Dometic in our 1999 Layton was still going strong when I sold it this summer. But, we only used it on occasion, no constantly. Does it get sufficient voltage/current to prevent damage? I don't have any experience with the Coleman products, but I think the unit on our new Outdoors RV is a Coleman, so will have to look.

I have two Dometic low profile a/c's on our '97 Dynasty that are 21 years old and still going strong. I did have to replace a fan motor on one of them about 10 years ago.

Probably depends on how much it gets used and whether it's maintained. In the NW the temps are such that I don't use the AC very often - my 92 works just fine.

Had one that was replaced after about a month, another is still going after 10 plus years.
