Upgrade your RV's comfort and climate control with the Dometic FreshJet 5 15,000 BTU Low-Profile Air Conditioner with Heat Pump. Designed as a direct replacement for Dometic Penguin II rooftop air conditioners, the FreshJet 5 combines powerful cooling performance, energy-efficient heating, quieter operation, and a modern low-profile design in a compact rooftop package.
Featuring a sleek black aerodynamic shroud and an ultra-low installed height of just 10.5 inches, the FreshJet 5 delivers exceptional cooling performance while improving roof clearance and reducing wind resistance. Whether you're replacing an aging rooftop air conditioner, upgrading your RV's climate system, or outfitting a new RV build, the FreshJet 5 provides modern performance without requiring modifications to your existing roof opening.
With a powerful 15,000 BTU cooling capacity and integrated heat pump technology, this rooftop unit provides year-round comfort by delivering dependable cooling during hot summer months and energy-efficient electric heating during cooler weather when shore power is available.
Same Fit. Upgraded Performance.
The FreshJet 5 was engineered to maintain the same mounting footprint as the popular Penguin II while incorporating significant advancements in comfort, efficiency, and reliability.
An upgraded high-performance motor and optimized blower assembly reduce interior sound levels by up to 9 dB in non-ducted applications, creating a quieter and more enjoyable RV environment. A redesigned aerodynamic shroud and enhanced airflow management improve overall cooling efficiency, while the integrated hard start system assists compressor startup and reduces electrical strain during operation.
The FreshJet 5 also utilizes environmentally friendly R-32 refrigerant, which provides improved heat transfer characteristics and increased operating efficiency while reducing environmental impact compared to older refrigerants.
