R134A automotive refrigerant is used in all Nomadic Cooling Air Conditioners. This makes it easy to repair, fill, or remove refrigerant anywhere in the world! Any traditional automotive air conditioner repair facility has the ability to fix, repair, and refill wherever you may be.

Sales tax is charged on every purchase. If you have a business or are tax-exempt for any other reason, don't hesitate to get in touch with Nomadic Cooling before purchasing or purchasing through our website. Once your documentation has been received at, you will quickly be refunded the corresponding amount.

As the outside air temperature increases, so do the demand for energy from the air conditioning unit. Nomadic Cooling tests our air conditioning units above 100F to determine maximum power consumption. 

Power consumption will be stated as follows: 12V @ 5/75 Amps

Example: This unit will consume up to 75 Amps when the outside temperature is over 100F. However, when the external temperature decreases, so will the demand for energy.

PLEASE REMEMBER: When designing your battery bank size energy consumption will fluctuate based on ambient temperature.

Our products are used in Jeep Wranglers, Land Cruisers, Range Rovers, Ford Transit, Dodge ProMaster, Chevrolet Express, Mercedes Sprinters vans, cut-away chassis, Class A RV, Class B RV, class C RVs, even boats! We also have an air conditioning unit for semi-trucks. If you can drive it, we can cool it👍

Yes, it is advised to run your system a minimum of twice monthly, even during the winter months!

If you already have a 14x14 rooftop opening, please install the air conditioner in the corresponding space. If you are adding a new unit, feel free to place it in the desired location. We recommend placement above the bed!

This is our favorite new device. We do not sell it, but we highly recommend it! Check it out and determine if it is suitable for your vehicle: Buck-Boost DC-DC Converter 25A / 50A / 100A

DC-DC Converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. The 50A Buck-Boost DC-DC Converter is a DC-DC converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. Since when the engine is running, these dynamos (powered by the onboard electronics of Euro 5 and 6 engines) do not always emit the correct charging current; a DC-DC converter is essential for charging the service battery properly.

Using the correct wire for your new air conditioner is essential! Use the chart (linked below) to determine the proper wire size for your application. 

Always use stranded insulated copper wire rather than solid strand wire for positive and negative connections.

*If installing in a traditional recreational vehicle, you cannot connect to existing household wires.

*When in doubt, use the next largest wire size. 

*Typically, 2AWG is standard or 2x 4AWG if space is limited.

The ability of an air conditioner to cool a vehicle or maintain a desired temperature depends on the vehicle's heat gain: Physical size of the vehicle window, area quality, amount of insulation exposure to sunlight, number of people inside the car, and outside temperature.

Generally, discharge air will be 15-20 degrees F or 8-12 degrees C more excellent than the air entering the unit.

For example, suppose the air entering the air conditioner is 80 degrees F or 27 degrees C (return air). In that case, the supply air (discharge air) into the vehicle will be 60-65 degrees F. or 15-19 degrees C. As long as this temperature difference is 15-20 degrees F, or 8-12 degrees C is being maintained, the unit is operating properly.

Again, give careful consideration to the vehicle heat gain variables. During extreme outdoor temperatures, the heat gain of the vehicle may be reduced by: parking the car in a shaded area, keeping windows and doors closed, using window shades (blinds and/or curtains), and avoiding the use of heat-producing appliances.

For a more permanent solution to high heat gain situations, additional vehicle insulation, window awnings, and/or window glass tinting should be considered.

A 14-1/4′′ x 14-1/4′′ (±1/2′′) square opening is required for installing this unit.

Roof construction with rafters/joists supports frames on a minimum of 16-inch centers. Minimum of 2 inches and a maximum of 5 1/2 inches distance between roof to the RV ceiling.

When determining your cooling requirements, the following should be considered: Size of RV, window area (increases heat gain), amount of insulation in walls & roof, the geographical location where the RV will be used, and personal comfort level required. The unit should be mounted slightly forward of center (front to back) for one unit installation and centered from side to side. For two-unit installations, install one unit 1/3 and one unit 2/3’s from the front of RV and centered from side to side.

Frost on a small portion of the cooling coil is not unusual. Under certain conditions, ice may form on the evaporator coil.

This is indicated by very cold output at very low airspeed, and the icing can be seen through the air inlet hole with the filter removed.

 If this should occur, make sure air vents are open and not obstructed. AC units tend to frost when the outside temperature is relatively low. This may be prevented by adjusting the thermostat to a warmer setting.

Should frosting continue, operate the unit on FAN ONLY setting until the cooling coil is free of frost; then resume regular operation.

You may decide to have a reputable builder/outfitter install your new Nomadic Cooling air conditioner. If you do, installation of the unit and the electronics that accompany the unit will cost around $1,000

*Cost guidelines only pertain to the ac unit, not the complete electrical system. 

If you are looking for a builder/outfitter in your area, please call us, and we can point you in the right direction!
