15,000 BTU Coleman RV Air Conditioners

Which Coleman Mach models are 15,000 BTU units?

The 15,000 BTU class in the Mach Series includes the Mach 15 (38204 series), Mach 3 Plus, Mach 10, Power Saver, and Mach 8 low-profile units. Common part numbers in this collection include 38204-066, 48204-066, 48004-966, and 47204-076. Always confirm your existing ceiling assembly is rated for 15,000 BTU before ordering, and verify whether your installation is ducted or non-ducted. For ducted setups, see the matching Coleman ceiling assembly for ducted installations.

Do I need a ducted or non-ducted ceiling assembly with my 15,000 BTU Coleman?

It depends on your RV's existing ductwork. Ducted coaches distribute air through ceiling vents tied into the roof, while non-ducted setups blow directly from the unit through a ceiling grille. The rooftop unit is often the same; the ceiling assembly is what changes. Match yours to the Coleman ducted ceiling assembly or the Coleman Power Saver HP ducted assembly if you have the heat-pump variant.

What is the difference between part numbers like 38204-066 and 48204-069?

The leading digits indicate the model generation and refrigerant type. Older Coleman 15K units used R-410A (38xxx series), while newer 48xxx units run on R-32 refrigerant to meet current EPA standards. The trailing digits (066, 069, 076) identify cooling-only versus heat-pump versus heat-strip configurations. Cross-reference your existing tag before ordering, and call 817-984-1852 if you need help decoding a legacy part number.

Does this collection include black low-profile Coleman ACs?

Yes. The Mach 8 Plus low-profile 15,000 BTU unit is available in black (48004-9669) and white, with a roof height under 10 inches for better aerodynamics and clearance under low garages and tree branches. If you also need related rooftop accessories, browse RV electronics for thermostats and soft-start kits that pair with the Mach Series.

How is a 15,000 BTU RV air conditioner shipped?

Rooftop AC units in this collection ship via truck freight due to weight and size, typically $99 flat. Inspect the carton for damage at delivery and note any issues on the freight bill before signing. Smaller parts and ceiling assemblies usually ship standard ground.
