  • Built for R32 Coleman-Mach Systems: Designed for compatible Coleman-Mach RV AC systems that use R32 refrigerant.
  • Durable, Lightweight Construction: Fiberglass basepan provides strength while helping reduce the AC unit's overall weight.

Features to know about

Replaces a Worn-Out Coleman-Mach Rooftop AC

When your old rooftop AC still fits the opening but does not keep the RV comfortable like it used to, replacing the outside unit may be the cleaner path forward. This Coleman-Mach Mach 8 Plus replaces the rooftop air conditioner and works with compatible Coleman-Mach R32 ducted or non-ducted interior components. The ceiling assembly and control components are sold separately, so you can match the new rooftop unit to the correct setup for your RV.

Low-Profile Cooling for Your RV

Rooftop equipment can add noticeable height to your RV, especially when you are watching clearance around garages, trees, or other overhead obstacles. The Mach 8 Plus measures just 8.3" tall, giving you 13,500 Btu of cooling power in an ultra-low-profile design. Its dual-motor system provides strong airflow on high speed when you need to cool down the cabin and quieter low-speed operation when you are maintaining a comfortable temperature at night.

Designed for Compatible R32 Systems

This rooftop AC is built for compatible Coleman-Mach systems that use R32 refrigerant. Before installing, confirm that your ceiling assembly, thermostat, and controls are compatible with this R32 rooftop unit. It works with compatible ducted or non-ducted Coleman-Mach setups, giving you options whether your system sends cooled air through ceiling ductwork or directly into the cabin.

Installation Help When You Need It

Swapping a rooftop AC means lifting the unit onto the RV, sealing the roof opening, and connecting it to the correct interior components. The fiberglass basepan provides a strong foundation while helping keep the unit's weight down, but at 90 lbs, having a second set of hands can still help when getting it onto the roof.

  • Looking for Coleman Mach 8 RV AC Unit
    Hey Bart, yes we do have just the upper unit of a Coleman Mach 8 RV AC unit with the part # CM78GR. Sounds like you already have the correct replacement lower air box but if you needed that as well the part # CM46RR is for if you have a non-ducted application or part # CM36RR for ducted. Did yours break?
