Replacement AC That Will Run An Atwood Heater  

Updated 08/12/2026 | Published 08/08/2026

Question:

I have a Mach 15 on a 2014 fusion impact. I need to replace it but i understand some units have issues working with the Atwood’s heater. Can you suggest a replacement unit? I like the advent with the built in thermostat for a ducted unit.

Hi Rick!

Though we do have options for you, the Advent Air Air Distribution Box with Built-In Thermostat # ADV57QR will only work with non-ducted units, unfortunately. They do not currently make an option with the built in controls for ducted units. With that said, check out the following two units:

Advent Air RV AC System w/ Wall Thermostat - 15,000 Btu - Ducted/Non-Ducted - Black - R32 # ADV62SR
Advent Air Low Profile RV AC System w/ Thermostat - 15,000 Btu - Ducted/Non-Ducted - White - R32 # ADV82SR

These are full replacements (AC unit, air distribution box, wall mounted thermostat, and a start capacitor) and can absolutely run an Atwood heater. I will admit to being preferrable to the white unit (even though it's a bit more expensive). White reflects heat better than black and I think that makes the AC work a little better. That's just my opinion though.

Where do you typically take your 2014 Fusion Impact?
