Low Profile AC Unit For Class C Motorhome - Complete RV Air Conditioning System With Thermostat

Published 05/07/2026

Question:

I’m looking for a low-profile black AC for my Class C and don’t want anything too bulky on the roof. Is the Advent Air 13,500 Btu unit just the rooftop piece?

Hey Kenji! Yes, the Advent Air # ADV76SR is the rooftop AC unit only, so you’ll need the interior components to complete the system. For this unit, pair it with the Advent Air air distribution box with wall-mounted thermostat # ADV98SR, which works for ducted or ductless setups.

The big reason to choose # ADV76SR is the low-profile design. It measures 10-1/8 inches tall and gives you 13,500 Btu of cooling, so it’s a good option when roof height matters. What AC setup is on your Class C right now, Kenji?
