Coleman 38208-0640 Mach 3 Plus 13,500 BTU Quiet PowerSaver RV Rooftop Air Conditioner Arctic White

The Coleman Mach 3 Plus 38208-0640 is a 13,500 BTU rooftop air conditioner engineered for RV comfort, combining the efficiency of the Mach III PowerSaver EZ technology with the reduced operating noise of the Quiet Series. This unit is the updated successor to the legacy SKU 38208-0660, featuring a refreshed Arctic White textured shroud design while maintaining identical cooling capacity, fitment, and performance specifications.

Key Features:

• 13,500 BTU nominal cooling capacity for effective climate control
• Mach III PowerSaver EZ technology — low amp compressor draw reduces electrical load and helps prevent circuit breaker trips
• Quiet Series design — engineered for reduced operational noise without sacrificing performance
• Ducted or non-ducted compatible — fits both ducted and non-ducted ceiling assembly configurations
• Large evaporator and condenser coils with raised lance fins for enhanced heat dissipation
• All-copper tubing with gas-flux brazed joints for long-term durability
• 320 CFM airflow delivery
• Fits standard 14" x 14" roof openings
• Operates on 120V AC power
• Pre-installed roof compression gasket included — no additional sealant required
• Arctic White finish to complement most RV exteriors
• Optional heater assembly available separately (adds 5,600 BTU heat capability)

The 38208-0640 replaces legacy part number 38208-0660. All compatibility, fitment, and performance specifications remain equivalent between the two part numbers — only the exterior shroud styling has been updated. The included pre-installed compression gasket ensures a secure, leak-resistant roof seal right out of the box.
