Questions & Answers

Have a Question?

Ask a Question
  • My 15000 BTU Dometic leaked and stopped working. I have heard nothing but good from Coleman. Will it replace without going threw any hassle. I live in the lower desert and am full timing in a 2019 Montana. It is ducted. Thank you.

    Switching from a 15000 BTU Dometic to a Coleman air conditioner for your ducted system in a 2019 Montana RV might be a straightforward process. However, ensuring compatibility with your RV's ducting and installation requirements is essential to avoid any hassle. It's a good idea to call Coleman Mach at 574-247-9235 to get specific installation and compatibility details. Consulting with an RV specialist or the manufacturer can also provide additional guidance.

  • Will this unit work good on a 12 volts power sourse ???

    This is a 120v unit.

  • Will this fit the rear unit of a 2006 Fleetwood Excursion?

    Coleman Mach AC's fit a 14x14 opening and are interchangable with the interior ceiling unit.  So if you have one it can be replaced.

Jeff L. (Chicago, US)
Food Trailer Air Conditioner

The shipping from Online RV Supply was very fast. The unit is an exact replacement to the original unit. So, it was a matter removing the inside brackets, unplugging the unit and undo the 120 wiring. We had the unit replaced in less than an hour. The new Coleman Mach 15 cools as it should.
