Proven Reliability in Real RV Conditions

RVs experience heat, vibration, constant movement, and varying power conditions — challenges most home AC systems never face.
Dometic and Coleman-Mach have spent decades engineering rooftop units that handle:

• Long-term vibration exposure

• Off-grid power fluctuations

• Extreme outdoor temperatures

• Road dust, humidity, and salt air

• Heavy use during long summer travel seasons

Simply put:
These are the units that last.
 

Strong Cooling Performance Across All RV Types

Whether you’re outfitting a compact camper or a 40-foot motorhome, both brands offer cooling capacities tailored to different rig sizes:

• 11,000 BTU for smaller trailers

• 13,500 BTU for mid-range RVs

• 15,000 BTU for large fifth wheels and Class A motorhomes

Their systems deliver strong airflow, fast cooldown times, and consistent performance even during 100°F+ heat waves.
 

Industry-Leading Support and Widely Available Parts

One of the biggest advantages of choosing Dometic or Coleman-Mach is parts availability. Need a capacitor, fan motor, blower wheel, control board, thermostat, or ceiling assembly?

You’ll find replacement parts for both brands readily available across the RV industry.

Why this matters:

• Repairs are easier

• Downtime is shorter

• Costs stay lower

• Compatibility is predictable

This is a huge reason why RV technicians overwhelmingly recommend these two brands.
 

Upgrade-Friendly Designs

Dometic and Coleman-Mach are committed to backward compatibility and modular designs. That means:

• Many new rooftop units fit the same openings as older ones

• Ceiling assemblies and control systems can be swapped or upgraded

• Both ducted and non-ducted configurations are supported

This makes upgrading or replacing an AC far less complicated — and often far more affordable.
 

Trusted by Manufacturers and Full-Time RVers

Walk through any major RV manufacturer’s lineup and you’ll see Dometic and Coleman-Mach units everywhere. They’ve earned that position by delivering systems that:

• Hold up to full-time travel

• Perform well in extreme climates

• Run efficiently on generator or shore power

• Are easy for service networks to support

These are the brands RVers rely on when cooling performance matters most.
