Features to know about

A Matched Kit That Simplifies the Install

One of the biggest headaches in RV repairs is figuring out which parts are compatible. This kit takes that off your plate. The rooftop unit, air distribution box, and thermostat are made to work together, so installation is smoother and the setup more reliable. Whether you're doing the install yourself or paying someone else to do it, having everything in one kit makes the process faster and less stressful.

Cooling Power for Bigger Spaces

With 15,000 Btu of cooling power, this system moves air through your ceiling ducts to cool larger RVs or drop the temperature fast in smaller ones. You'll feel the temperature shift within minutes, not hours, so your RV stays comfortable even in the middle of summer.

Easy, Accessible Control at the Ceiling

The air distribution box gives you control right at ceiling level. Open the louvers for direct cooling into the cabin or close them to push air through your ducts. The slim, low-profile design leaves you with more overhead clearance inside, and the swing-open grille makes it easy to reach and wash the filter. No tools needed. Just pull, rinse, and snap it back into place.

Add Heat for Chilly Mornings

Sometimes it's not cold enough to run the furnace, but it's too chilly to be comfortable. This system is prepped for a 5,600 Btu heat strip (sold separately), which is a simple way to take the edge off on those in-between mornings. It's easy to install and helps your space warm up without the noise or power draw of a full furnace cycle.

Your old AC couldn't keep up. This ducted kit delivers powerful cooling through every vent, with matched components for a smooth install and the reliability to keep your RV comfortable season after season.

by:

The units were in great shape as they were delivered. when I was putting in my order the screen said Sunday delivery, when I submitted the order it changed to Monday, when I tracked the order it said Tuesday. It was Tuesday that it was delivered. that is the only negative thing about my order. everything else is as ordered. I did not realize I ordered the units with the control knobs but that was my mistake. I really needed the ones with the thermostat controls. If there is a kit to switch it from the knobs to the thermostat I would love to know what it is.

  • Replacement for Coleman-Mach AC on Travel Trailer
    Hey Kyle! You can replace your old Coleman-Mach AC with one of the new ones. However, you will need to replace the thermostat and air distribution box as well. All of the new AC units use R32 refrigerant following the 2025 EPA guidelines so any old R410A components aren't compatible. We have 13,500 Btu or we have the 15k units if you want to upgrade. You can choose from the following based on color and ducted/ductless: -Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu...

  • Difference Between Coleman-Mach Roughneck Mach 15 and Signature Mach 15
    Hey Bill, great question! The Signature Mach 15 is your standard AC unit which is probably what you want. The Roughneck has a fortified interior making it ideal for off-road and heavy industrial vehicle applications. Basically it is made to take more of a beating. If you had an old carrier and it is wearing out from use over time (I'm guessing that is the case here) the Signature is what you want. If you have been off-roading with your trailer lately and it killed off the Carrier then...

  • Can Furrion Chill HE Replacement AC Replace Coleman Mach 8 in 2020 Vanleigh Beacon
    Hi Jake; the Furrion Chill HE Replacement RV Air Conditioner for Coleman Setup # FR32PV is an old kit that is on its way out. We no longer recommend replacing just the AC unit, and can't guarantee this will work as a plug and play replacement. We have had customers in the past successfully swap them out, others have found the connector doesn't work, sometimes the systems don't work together, and occasionally mixing up the AC with other components burns out the air distribution box (ADB)....

  • Does The Coleman-Mach Signature System Run Quiet?
    Hey Gloria, This Coleman-Mach Signature Ac Unit # CM52RR is the same as most standard RV ac units when it comes to noise. A typical ac unit on an RV runs around 55-70 decibels which is comparable to background noise in a busy restaurant. It is hard to really put a number to the sound since everyone hears differently. I would say this unit does not run quiet, but it is also not loud. What ac system do you currently have?

  • Of Plug-In Replacement For Coleman Mach 15 AC Unit On 2016 Keystone Impact TT Toy Hauler
    Hello Shayne, thanks for reaching out. We do have an option for replacing your Coleman Mach 15 AC, but I am sorry to say there are no plug-and-play replacements for this. Reason being is all new RV AC units changed over to a new R32 refrigerant starting in 2025. These new units are not backwards compatible with old pre 2025 AC systems. So you will need to replace your rooftop unit, controller, distribution box and thermostat. For that, I recommend the following: - Coleman-Mach Signature...

  • Can Coleman-Mach AC Replace Dometic Duo-Therm on 2014 Forest River Travel Trailer
    Hey Earl! Yes, the Coleman-Mach Signature Mach 15 AC system can replace your old Dometic Duo-Therm. These are new R32 refrigerant units (everything is as of 2025) so a complete replacement will be necessary. You can choose from the following based on ducted/ductless and the color: -Coleman-Mach Signature Mach 15 Air Conditioner System - Ductless - 15,000 Btu - Textured White # CM43RR -Coleman-Mach Signature Mach 15 Air Conditioner System - Ductless - 15,000 Btu - Polished White # CM93RR -Coleman-Mach...
