Choose a rooftop air conditioner for a motorhome or expedition vehicle

RECREATION & TRANSPORT

Choose a rooftop air conditioner for a motorhome or expedition vehicle

Select the rooftop unit around the living-space heat load, roof structure, available voltage and realistic usable battery energy. Nominal battery capacity alone does not establish runtime.

BEST STARTING POINT

A self-contained or packaged rooftop unit sized to the insulated living space, supported by a verified roof opening, structure and electrical system.

SYSTEM APPROACH

How this comes together

01

Size the cabin

Use internal volume, glazing, insulation, occupants and design ambient to establish the cooling duty.

02

Check the roof

Confirm opening size, structural support, overall height, airflow clearance and water management.

03

Plan runtime

Calculate usable battery energy, charging capacity and other loads at the expected operating current.

BEFORE BUYING

Information that confirms the selection

Provide what you know. Unknown items can be resolved during technical review.

  • Vehicle and living-space dimensions
  • Insulation, glazing and occupant count
  • Roof opening and allowable unit dimensions
  • 12 V or 24 V system
  • Battery chemistry and usable capacity
  • Alternator, solar and shore-charging capacity
