Question:
Is there a version like this that also has a heat pump? I am replacing the Dometic form my 1999 Newmar Mountain Aire. It is a ducted system. The RV does have a furnace, but I was hoping I could find an AC with heatpump to use less propane. Thanks for the help.

Hey Christopher! A heat pump isn't available for the old Furrion you were referencing. Also, everything has moved from the old R410A refrigerant to R32 following the 2025 EPA regulations. Since parts aren't backwards compatible you will need a complete system replacement for your old Dometic setup. For an AC that comes with a heat pump I recommend one of the new GE Appliances AC systems. You can choose from the following:
-GE Appliances Deluxe Plus RV AC System w/ Heat Pump - Ducted - 15,000 Btu - White # GE85ZR
-GE Appliances Deluxe Plus RV AC System w/ Heat Pump - Ducted - 15,000 Btu - Black # GE75ZR
-GE Appliances Low-Profile RV AC w/ Heat Pump - Ducted - 15,000 Btu - White # GE38RR
-GE Appliances Low-Profile RV AC w/ Heat Pump - Ducted - 15,000 Btu - Black # GE26RR
Another option would be an AC system with a heat strip instead of a heat pump. All of the Advent Air systems have the option to add the Electric Heat Strip # ADV34QR. These are also a little more reasonably priced. If that sounds good you can choose from the following:
-Advent Air RV AC System - 15,500 Btu - Single Zone - Ducted - White - R32 # ADV99QR
-Advent Air RV AC System - 15,500 Btu - Single Zone - Ducted - Black - R32 # ADV69QR
Any big trips coming up with your motorhome?

Would the Coleman Mach 8 Plus 15k BTU AC/HP work for my rig? I am replacing the roof so possible to change thermostats, etc. What is not clear also is the there seem to be other parts I must purchase but not clear what they are?

Hey Christopher, how did things go with the GE AC system with the heat pump for your Mountain Aire? Did it give you the propane savings you were hoping for? Your update could make it easier for others upgrading older ducted setups.
