Dometic Air Conditioning

Dometic Air Conditioning: Built for Life Without Walls

When it comes to mobile climate control, few names carry more weight than Dometic. Across the RV, marine, and specialty vehicle markets, Dometic has earned a reputation as a benchmark brand for air conditioning systems that are engineered to perform in the harshest, most demanding real-world conditions. Whether you're crossing the desert in a Class A motorhome, anchored overnight on a powerboat, or sleeping in a travel trailer on a sweltering summer night, Dometic offers a purpose-built AC solution for the job.

A Product Line Built Around Every Application

Popular rooftop series include the Brisk II, Penguin II, and FreshJet — each designed for different priorities in performance, profile, and installation flexibility. Rooftop AC units are the most popular Dometic models for RVs and campers; positioned on the roof, they utilize external airflow for improved efficiency and are ideal for larger RVs or travel trailers.

• Brisk II: A rugged and reliable 15,000 BTU rooftop air conditioner designed for demanding applications. Built with stainless steel components and e-coated coils, it is engineered for long-lasting performance, even in harsh marine and outdoor environments where corrosion can be a concern. It supports both ducted and non-ducted installation configurations, allowing it to fit seamlessly into a variety of setups.
• Penguin II: The Penguin II features a high-performance motor and fan that helps reduce wind resistance — a valuable feature as wind drag on your RV while driving at high speeds can reduce gasoline and fuel efficiency. Available in cool-only and heat pump variants, with capacities ranging from 11,000 to 15,000 BTU.
• FreshJet Series: Fresh design, superior cooling performance, optimized airflow, and amazingly quiet operation are the outstanding features of Dometic's FreshJet generation of motorhome air conditioners. At just 64 pounds, the FreshJet 3 is 14 percent lighter than previous models, and its modern, streamlined design requires up to 28 percent less refrigerant. Dometic's custom blower system provides 15 percent more even airflow and a 13 percent higher cooling capacity than comparable ACs.
• Cool Cat: The Cool Cat blends cooling and heating in a compact, under-bench design ideally suited for small travel trailers, with a heat pump system that offers year-round climate control without rooftop installation.
• RTX Series (DC-Powered): The RTX models are engineered for trucking and off-grid lifestyles, running silently on 12V or 24V DC power with up to 12 hours of cooling, while a split inverter compressor ensures high efficiency and minimal battery draw.
• Marine Air / EnviroComfort: The Marine Air EnviroComfort AC with Reverse Cycle Heat upgrades onboard climate control with efficient year-round comfort, delivering powerful cooling and reverse-cycle heating through a compact system with digital control and flexible installation options.

What Sets Dometic Apart in AC Design

Dometic air conditioners feature low power consumption, quiet operation, and precise temperature control — ensuring a pleasant indoor climate wherever you roam. Noise reduction is a priority across the lineup: thanks to the integration of rubber bushings and EPP foam, units operate with minimal vibration and noise, providing a more comfortable environment without disruptive sounds. For marine applications, Dometic provides complete climate systems in a variety of capacities, all designed for fast and easy retrofitting, with optional air distribution kits for additional cabins.

Dometic air conditioners offer models running on AC (110V/115V/230V) as well as DC (12V/24V) units, meaning there is a configuration to match almost any electrical setup — from shore power to solar and battery systems. E-coated evaporative coil design provides upgraded coil coverage and corrosion resistance, a crucial advantage for both marine environments and humid climates. The FreshJet 3 can be installed in RVs with or without ducting and is backward compatible with various Dometic and non-Dometic brand controls and air returns, making it a versatile retrofit option even in older rigs.

From lightweight rooftop units to whisper-quiet under-bench systems and rugged off-grid DC coolers, Dometic's air conditioning catalog addresses the full spectrum of mobile cooling needs.
