Coleman Mach 8 Plus RV AC | 37004-079 | 15K BTU | Heat Pump | Black

Upgrade your RV cooling with the Coleman Mach 8 Plus RV Air Conditioner with Heat Pump — Black (Part #37004-079). Industry's lowest 8" aerodynamic profile with revolutionary fiberglass basepan for superior strength and reduced weight. 15,000 BTU cooling, integrated heat pump, R-32 refrigerant, and 300 CFM airflow. Fits any 14" × 14" opening — versatile ducted OR non-ducted installation.

Want a Version with Built-In Condensate Pump?

Same platform is available with a built-in condensate pump for active moisture management: see the Coleman Mach 8 Plus with Condensate Pump (37024-079). Meaningful upgrade for buyers who want to eliminate water pooling on the AC housing or RV roof — this 37004-079 version does NOT include the condensate pump.

Don't Need Heat Pump?

For a cool-only Mach 8 Plus at a different price point, see the Coleman Mach 8 Plus Cool-Only (37204-079) — same 15K BTU output, same 8.3" ultra-low profile, same fiberglass basepan — cool-only without the heat pump.

⭐ 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 — better fuel economy 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 + Heat Pump

High-capacity year-round comfort from a single low-profile unit:

• 15,000 BTU cooling capacity
• Integrated heat pump — supplemental electric heating without propane usage
• 300 CFM airflow — consistent, refreshing air movement
• Dual-motor design — consistent cooling on both high AND low speeds

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.

⚠️ Ceiling Assembly Required — Sold Separately

The 37004-079 is the upper (rooftop) unit only. A complete installation requires a compatible ceiling assembly (ducted or non-ducted, sold separately) based on your configuration.
