Coleman Mach 15 Quiet Power Saver RV AC | 38209-0640 | 15K BTU

Upgrade your RV comfort with the Coleman Mach 15 Quiet Power Saver RV Air Conditioner (Part #38209-0640 / Legacy 38209-0660) in arctic white — 15,000 BTU cooling capacity with cutting-edge Power Saver EZ technology for low-amp compressor draw and quiet operation. R-32 refrigerant, 320 CFM airflow, fits any standard 14"×14" roof opening. Updated 2026 arctic white textured shroud design (direct replacement for legacy 38209-0660).

⭐ Mach 15 Power Saver EZ Technology — Standout Feature

Key differentiator vs the standard Mach 15: Power Saver EZ technology delivers meaningful energy efficiency:

• Low amp compressor draw — cost-effective operation
• 11.2A cooling load — significantly lower than standard 15K BTU units
• Meaningful for RVs on 30-amp service or generator power — leaves more amperage for other appliances
• Quiet operation — minimal noise disturbance without compromising performance

⭐ 2026 Production Change — Updated Shroud Design

Important production note: Coleman has implemented a running production change to the Mach 15 Power Saver rooftop AC line:

• New model: 38209-0640 — features the updated 2026 arctic white textured shroud design
• Legacy model: 38209-0660 — being phased out
• Direct replacement: The 38209-0640 is the direct successor to the 38209-0660

Customers ordering either SKU may receive the new 38209-0640 due to the production change. The compatibility, cooling capacity, fitment, functionality, and performance specifications remain equivalent — the primary change is the updated exterior shroud styling.

Also Replaces R-410A Predecessor

Cross-references all these part numbers as the same air conditioner model:

• 38209-0640 (current, updated 2026 shroud)
• 38209-0660 (legacy)
• 48209-0660 (R-410A predecessor)

⭐ 15,000 BTU Cooling — 320 CFM Airflow

• 15,000 BTU cooling capacity — high-output cooling for large RVs, motorhomes, and demanding heat conditions
• 320 CFM airflow — consistent, refreshing air movement throughout the RV
• Large evaporator and condenser coils with raised lance fins — effective heat dissipation, enhanced cooling performance
• Cool-only — no heat pump (for heat pump version, see standard Mach 15 38004-064/067)

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.

Need Heat Pump Instead?

This 38209-0640 is a cool-only Power Saver EZ variant. For heat pump-equipped Mach 15 options, see:

• Coleman Mach 15 Heat Pump (38004-067) — Black
• Coleman Mach 15 Heat Pump (38004-064) — Arctic White

The heat pump variants provide year-round comfort — cooling AND supplemental electric heating — but do not include the Power Saver EZ low-amp technology.

⭐ 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.

⭐ Pre-Installed Roof Compression Gasket

All new replacement RV air conditioner units come with a pre-installed roof compression gasket on the base of the unit. Provides a proper seal between the AC and the RV roof — ensures a secure and leak-resistant installation. No additional sealant or roof gasket required for the rooftop AC unit.

⚠️ Ceiling Assembly Required — Sold Separately

The 38209-0640 is the upper (rooftop) unit only. A complete installation requires a compatible ceiling assembly (ducted or non-ducted, sold separately) based on your configuration.
