Dometic Low Profile RV Air Conditioners

What makes a Dometic low profile RV air conditioner different from a standard rooftop unit?

A Dometic low profile RV air conditioner uses a shorter shroud than a standard rooftop unit, so it adds less height to your roofline. That matters when your RV is close to a clearance limit for a storage building, carport, drive-thru, or low bridge. It also leaves more space for solar panels and antennas. Cooling output stays in the same range as standard-height units, so you give up height, not BTU. Before ordering, measure the clearance you currently have and compare it to the height listed on each product page in this collection.

Will a Dometic low profile air conditioner fit my existing roof opening and ceiling assembly?

Dometic low profile rooftop units in this collection mount over the standard 14"x14" RV roof opening used by most rooftop air conditioners. The ceiling assembly has to match your RV's air distribution. A ducted unit sends air through channels in the ceiling. A non-ducted unit blows air straight down through a ceiling grille. Check which setup your RV has before ordering, because the ceiling assembly is usually sold separately. You can find compatible ceiling assemblies, thermostats, and gaskets in our RV air conditioner parts and accessories collection.

Should I choose a 13,500 BTU or 15,000 BTU low profile unit, and do I need a heat pump?

A 13,500 BTU unit covers most single-AC travel trailers and smaller motorhomes. A 15,000 BTU unit is the better match for longer coaches, RVs with large windows, or regular use in hot climates. On 30-amp service, a 15,000 BTU unit leaves less headroom for other loads, so check your power budget before ordering. A heat pump model also heats the cabin with the same rooftop unit, and it works best when outside temperatures stay above roughly 40°F. Below that, you will still rely on your furnace. To compare these Dometic options with other brands and profiles, see our full RV air conditioners selection or our Coleman RV air conditioners.

What is included with a Dometic low profile RV air conditioner, and how does it ship?

Most Dometic low profile listings include the rooftop unit only. The ceiling assembly, the thermostat, and in some cases the mounting gasket are sold separately. Each product page states what is included, so read that note before checking out. Rooftop air conditioners ship by freight because of their size and weight. Freight details are listed on each product page so you know the cost before you order. If you are replacing an older Dometic or Duo-Therm unit and are not sure which model or ceiling assembly matches your RV, text or call 817-984-1852 with the model number from your current unit's data plate.
