Big Cooling Capacity for Larger Rigs

The Blizzard NXT delivers a powerful 15,000 BTU of cooling — enough to keep larger RVs, fifth wheels, and motorhomes comfortable even on the hottest travel days.

Heat Pump for Year-Round Comfort

The integrated heat pump takes the chill off cool mornings and brisk evenings, giving you supplemental heat without firing up the propane furnace. It's a smart, energy-efficient way to extend your comfortable camping season into the shoulder months.

Quiet, Efficient, Easy to Install

Engineered for quiet operation and energy-efficient performance, the Blizzard NXT keeps the soundtrack of your campsite peaceful while keeping running costs in check. It fits a standard 14" x 14" vent opening, and every new unit arrives with a pre-installed roof compression gasket on the base, creating a proper seal between the AC and your RV roof — so no additional sealant or roof gasket is needed for a secure, leak-resistant install.
