• Will Coleman Mach 3 AC Rooftop Unit Work On Small Camper Build Instead Of Full Complete AC System?
  Hey Amelie! You can still use the Coleman-Mach AC system # CM97RR for a ductless install, but you’ll need to add the correct air distribution box since the rooftop unit does not include the inside ceiling assembly. For a ductless setup, pair # CM97RR with the Coleman-Mach Deluxe Air Distribution Box # CM46RR. That gives you the rooftop 13,500 Btu unit plus the ceiling assembly needed for direct airflow into the camper. If you want light electric heat later, the Coleman-Mach heater kit...

• Replacement Options For Older Coleman Mach 13,500 BTU AC Unit On Older Keystone RV
  Hey Boone! If the 13.5K Coleman-Mach kept up before, I’d stay in that same size range with the Coleman-Mach Signature Mach 3 # CM97RR. It’s a 13,500 Btu rooftop unit, so you’re not oversizing the replacement just because the old one failed. Just keep in mind # CM97RR is the rooftop AC only. If your current system is older and does not specifically show R32 compatibility, plan on replacing the inside parts too since they aren't backwards compatible: # CM46RR for ductless or # CM36RR for...

• Replacement Coleman-Mach Rooftop AC Unit In Camper 13,500 BTU
  Good afternoon Nia, the Coleman-Mach Signature Mach 3 # CM97RR is a good 13,500 Btu rooftop AC option, but it is the rooftop unit only. Since this is one of the newer R32 refrigerant units, you would only be able to replace just the rooftop AC by itself if your current Coleman-Mach setup already uses compatible modern R32 components. If your existing AC system is more than a couple years old, you'll need to replace the matching interior components too so everything works together correctly....

• Replacement Coleman Mach AC Unit 13,500 BTU For Midsized Camper
  Hey Rafael! I'd go with the Coleman-Mach Signature Mach 3 # CM97RR if you want the 13,500 Btu rooftop unit. Just keep in mind it’s the rooftop AC only, so you’ll need the correct air distribution box to complete the setup unless you already happen to have the modern R32 refrigerant. The new units aren't backwards compatible so you'd need to replace the other components if you have the older R410 refrigerant which got changed over a couple years ago. For a ductless camper, use the Coleman-Mach...

• Is There A Replacement Coleman Mach AC Unit For My Camper?
  Hey Dev! The Coleman-Mach # CM97RR is a good 13,500 Btu replacement option, but it’s the rooftop unit only. If your current Coleman setup is not a newer R32 system, you’ll need updated compatible interior parts too - the newer R32 rooftop units are not meant to bolt onto older ceiling assemblies and controls. For a ductless setup, use the Coleman-Mach Deluxe Air Distribution Box # CM46RR in addition to the AC unit mentioned above. For a ducted setup with ceiling vents, use the Coleman-Mach...

• How Do I Know Which Rooftop AC Unit I Need For Old Coleman Setup On RV?
  Hey Kiana! The easiest place to start is the data tag on your current rooftop unit. If your existing Coleman-Mach system does not specifically show R32 compatibility or if it's from before 2024, it's probably the older style and I'd replace the matching interior parts along with the rooftop unit. There should also be part numbers on the ac unit or ceiling unit to cross reference. The Coleman-Mach Signature Mach 3 # CM97RR is the 13,500 Btu rooftop unit only for the new R32 refrigerant...

• Can I Add Second AC Unit To Bedroom Of RV For When Off-Grid And Don't Need To Cool The Whole RV?
  Good morning Yasmin, yes a 13,500 Btu unit can make a lot of sense for a bedroom second AC, especially if that room is smaller and you do not need the same capacity as the main living area. I’d look at the Coleman-Mach Signature Mach 3 # CM97RR. If the bedroom is ductless, pair it with # CM46RR. If it ties into ceiling ducts, use # CM36RR. I’m assuming it’s non-ducted and doesn’t have ceiling vents in that prepped AC spot. If it’s not prepped at all and you’re cutting a new hole in the...

• Should I Replace Just The Coleman AC Unit Or Replace The Whole System In My Camper?
  Hey Andre! If your current Coleman-Mach system is already a modern R32 setup, then the Coleman-Mach Signature Mach 3 # CM97RR would work as a rooftop-unit-only replacement. An easy way to check is to look at the data tag on your current rooftop unit or the paperwork for your ceiling assembly - if it doesn’t specifically show R32 compatibility, I’d assume it’s the older style. New units are not backward compatible since the R32 refrigerant change. Assuming you need a whole new system, for...

• Replacement Ducted AC Unit Setup For 2020 Forest River Salem With Ceiling AC Ducts
  Hey Amara! The Coleman-Mach # CM97RR is the rooftop AC unit only, so you’ll still need the correct interior components to finish the system. Since your Salem has ceiling ducts, you’d pair it with the Coleman-Mach ChillGrill Air Distribution Box # CM36RR. That setup gives you a 13,500 Btu cool-only Coleman-Mach system for a ducted RV. The rooftop unit fits a standard 14-1/4 inch x 14-1/4 inch opening and has a listed cooling draw of 12.8 amps, which makes it one of the easier ones here...

• Recommended Modern AC System For Older Noisy Air Conditioner In Camper With 30A Hookup
  Good morning Etta, yes the Coleman-Mach Signature Mach 3 # CM97RR is a good option if you want to stay with a 13,500 Btu unit instead of stepping up to a 15K. It has a listed cooling draw of 12.8 amps, so it’s a practical choice for a 30 amp camper when you’re still trying to manage other RV loads. Just keep in mind # CM97RR is the rooftop unit only. If your current setup is older and not already R32 compatible, you’ll need the matching interior parts too: # CM46RR for ductless or # CM36RR...
