Question:

Hey Bob.

Great question I completely understand wanting to keep everything running from one wall control without creating extra wiring headaches and extra parts.

At this time, there isn’t a control board available that will allow a single-zone Dometic 5-button thermostat to operate both a new AC and your Aqua Hot from the same control. The Aqua Hot would still need to be operated through its existing control system.

Hey Melanie. The reason you can't find a replacement for your GE ARC15AACBL2 15,000 btu air conditioner is because they phased them out. In 2025 all RV AC systems had to change over to a new coolant called R32. This was a EPA mandated decision.…

Hey Mike! The Advent Air RV Air Conditioner #ADV74QR is only designed to work with an R32 setup. Your old unit is going to be R410A, so the old components won't be compatible. Since everything moved to R32 last year due to EPA regulations a…

Hi Collin, welcome back! The most economical replacement is going to be from Advent Air. You will need a complete system since everything moved to R32 refrigerant. If your upgraded thermostat is R32 compatible, or a smart thermostat that got a…
