Question:

I have a 2008 Monaco Dynasty with three ducted AC units. I’m looking at possibly replacing a rear AC it has a Dometic MODEL 630516.331 PROD. NO. 991760410 SERIAL NO. 73901634. I use one micro air thermostat that controls all three. I’m looking for at least 15,000 BTU heat pump if it’s bigger that’s a plus that will work with my current system.

Thanks for stopping by Michael, happy to help!

Micro-Air states, "The EasyTouch RV Thermostat will work with all BTU ratings and all rooftop AC units made by Coleman and Dometic to start with. Most other brands will be added later." Based on that, I can't confirm that the GE AC and your existing Micro-Air thermostat will communicate. Our GE rep wasn't able to confirm compatibility either, so I'd recommend reaching out to Micro-Air directly to verify.

The GE Deluxe Plus system has its own wall mounted thermostat to control the AC. So, if you're okay with one of your AC units being controlled independently, I'd recommend the GE Deluxe Plus RV AC System with Heat Pump # GE75ZR to replace your Dometic Duo-Therm Penguin. It's a 15,000 BTU ducted system with a built in heat pump, making it a comparable replacement.

In which room is the AC you're planning to replace? How much do you use the AC in this area?
