Upgrade your RV cooling with the Coleman Mach 8 Plus RV Air Conditioner — Black (Part #37204-079). Industry's lowest 8" aerodynamic profile with revolutionary fiberglass basepan for superior strength and reduced weight. 15,000 BTU cooling capacity, R-32 refrigerant, and 300 CFM airflow. Fits any 14" × 14" opening — versatile ducted OR non-ducted installation.

Need Heat Pump or Condensate Pump Too?

This 37204-079 is the cool-only Mach 8 Plus — no heat pump, no condensate pump. The Mach 8 Plus platform is also available with additional features:

Same ultra-low profile and fiberglass basepan across all three — choose based on your heat pump and condensate pump requirements.

⭐ Industry's Lowest 8" Aerodynamic Profile

Standout feature vs standard rooftop ACs: at just 8.3" tall, the Mach 8 Plus has the industry's lowest aerodynamic profile. Meaningful benefits:

  • Reduced wind resistance — enhances fuel efficiency by reducing drag while towing/driving
  • Improved roof clearance — meaningful for low-clearance parking, garage storage, driveway constraints
  • Cleaner aesthetic profile vs standard-height AC shrouds

⭐ Revolutionary Fiberglass Basepan

Coleman Mach 8 Plus introduces a fiberglass basepan — a meaningful engineering upgrade over standard construction:

  • Superior strength
  • Reduced weight
  • Corrosion resistance — meaningfully better than steel over time

⭐ 15,000 BTU Cooling with Dual-Motor Quiet Operation

Powerful cooling in a compact package:

  • 15,000 BTU cooling capacity
  • 300 CFM airflow — consistent, refreshing air movement
  • Dual-motor design — consistent cooling on both high AND low speeds, even during the quietest of nights

R-32 Next-Generation Refrigerant

Uses R-32 refrigerant — the next-generation low-GWP refrigerant that replaces R-410A in current Coleman Mach production:

  • Approximately 70% lower global warming potential than R-410A
  • Zero ozone depletion potential
  • Improved energy efficiency in many operating conditions vs R-410A
  • Meets 2025 EPA AIM Act refrigerant requirements

Note: R-32 is classified as A2L (mildly flammable) — service must be performed by a qualified technician using appropriate equipment.

⭐ Universal 14" × 14" Roof Opening Fitment

Fits any 14" × 14" RV roof opening — the industry-standard AC roof opening size. Easy replacement for most existing rooftop AC installations without cutting sheet metal.

Ducted OR Non-Ducted Installation

Versatile installation flexibility — works with both ducted AND non-ducted systems. Suits varied RV configurations and preferences.

Multiple Part Number Match — Same Unit

Both of the following part numbers correspond to this same air conditioner model:

  • 37204-079
  • 47204-079

⚠️ Ceiling Assembly Required — Sold Separately

The 37204-079 is the upper (rooftop) unit only. A complete installation requires a compatible ceiling assembly (ducted or non-ducted, sold separately) based on your configuration.
