Coleman Air Conditioning
Coleman 47103A4051 Soft Start Capacitor Kit for Mach 8 & Mach 9 Air Conditioners
Coleman Air Conditioning: The RV Industry Standard Since 1967
When it comes to climate control on the road or water, few names carry the weight of Coleman. Since the very first RV air conditioner came on the market in 1967, the name Coleman has been synonymous with staying cool and comfortable on the road. Decades later, that legacy shows no signs of slowing down — Coleman air conditioners come OEM on many campers and RVs because camper manufacturers know that they are a great unit.
A Lineup Built for Every Rig
Browse the full range of Coleman air conditioning products and you'll quickly see how thoughtfully the Mach series is structured to serve every type of RV owner. Coleman-Mach air conditioners can be installed on all kinds of recreational vehicles including Class A, B, and C motorhomes, 5th wheels, towable trailers, pop-ups, and truck campers, as well as specialty vehicle and marine applications.
- Mach 3 Plus: The Coleman-Mach 3 Plus features large evaporator and condenser coils with raised lance fins to help dissipate heat, delivering 320 CFM airflow. It's one of the most popular and versatile units in the lineup, well-suited for a wide range of RV sizes.
- Mach 8: The smallest of the bunch measures only eight inches tall but features two motors with two speeds — a larger motor operating at 300 CFM for hotter temperatures and a smaller motor ideal for quiet nighttime use. Its lower-profile shroud means less aerodynamic drag and better fuel efficiency.
- Mach 15: The Mach 15 is equipped with a 1/3 HP fan motor — the largest used in an RV air conditioner — delivering cool air at an incredible 320 CFM. It's the go-to choice for larger rigs and extreme heat conditions.
- Everest VS-18: The Coleman-Mach Everest VS-18 delivers high-powered adaptive cooling for travel trailers, fifth wheels, and motorhomes. Soft-start technology reduces noise and electrical strain, while intelligent power scaling supports efficient performance in hot climates and off-grid camping.
Technology That Sets Coleman Apart
Coleman-Mach units are engineered with features that go beyond basic cooling. Coleman-Mach air conditioners have been upgraded to use R32 refrigerant due to its lower environmental impact and improved energy efficiency. R32 has a lower global warming potential, meaning it contributes less to climate change if released into the atmosphere, and it allows for more efficient heat transfer, potentially leading to lower energy bills.
Integrated soft-start technology, found across newer models, reduces compressor startup surge — helping lower startup noise and reducing electrical strain on generators, campground hookups, and RV power systems. For marine environments, Coleman units are built with protection against the added vibration and saltwater corrosion experienced on water, making them a reliable investment season after season.
Made in America, Trusted Everywhere
Coleman-Mach is the only RV air conditioner assembled in America, with centrally located manufacturing in Wichita, Kansas — a point of pride that speaks to the brand's commitment to quality control and domestic craftsmanship. The full product portfolio includes not just air conditioners, but also heat pumps, ceiling assemblies, thermostats, conversion kits, and AC accessories — making Coleman a one-stop shop for complete RV climate control.
