How We Decided

RV air conditioners have a specific cooling capacity that indicates the speed the conditioner cools the air. Each RV air conditioner is measured in British Thermal Units per hour (BTU/H). The higher the figure, the quicker the temperature drop, so you feel cooler in less time. Therefore, we opted for units measuring an average of 13,000 BTU/H – except for two portable designs – as this measurement will quickly cool down your RV. Anything above 13,000 BTU/H is ideal for traveling in warm climates and larger RVs (recreational vehicles).

When purchasing an air conditioner for your RV, you want it to take up minimal space. Therefore, apart from two portable units, we only focused on rooftop units (with 1 exception), so you don’t have to place your air conditioner on the floor. This design also helps to evenly distribute the airflow in your RV, compared to a unit pointing at a piece of furniture. Rooftop units also use brisk air from outside to cool the unit, thus saving energy in the long run.

Finally, we also researched air conditioners with various blower speeds, so you can adjust the unit for more or less power consumption. We found it important that the air conditioners have a minimum of two speeds for variety when you need more cool air.

Other models that just missed our list include the AIRXCEL Mach 15 AC, the Dometic Brisk II Rooftop Air Conditioner, and the DOMETIC PENGUIN II. 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 325 CFM. The Dometic Brisk II AC Unit comes in two different colors: Polar White (B59516.XX1C0) and Black (B59516.XX1J0). Both Brisk II models feature large air vents that promote superior airflow and cooling capacity. Finally, the Dometic Penguin II is a low-profile, stylish model that boasts 13,000 BTU. The Penguin II features a high-performance motor and fan that deliver superb cool performance. But, compare Dometic IBIS 4 vs Harrier to see which A/C reigns superior.

Buyer’s Guide to RV Air Conditioners

Important Factors to Consider Throughout Your Search

  1. Cubic Feet Per Minute (CFM)
    You should purchase an air conditioner based on the size of your RV. An average RV air conditioner will cool 300 cubic feet per minute, so you should consider the area of your vehicle in comparison to the unit. Your RV’s size will also determine the best BTU/H. Generally speaking, a size of around 200-300 feet will require 5,500-7,000 BTU/H. For 350-500 feet, look for a unit measuring 8,000-12,000 BTU/H to keep your RV cool quickly.
  2. Heating Capacity
    If you tend to travel in both cold and warm climates, opt for a unit that also comes with a heat pump to keep you warm when temperatures drop. This saves room by not having to purchase an air conditioner and heater. Research the BTU/H of the heating facility. Some units have as much power with heat as they do with cool air.
  3. Wattage
    Finally, research the air conditioner’s wattage, as this determines the energy the unit uses in operation. The higher the BTU/H, the bigger the wattage you’ll need. For example, a 7,000 BTU/H requires 1,700 watts to start up, and around 600 watts during use. Most people want the most powerful air conditioner to get cooler quickly, but if your RV’s battery isn’t big or powerful enough to operate the machine, the air conditioner won’t reach its maximum potential.
  4. Installation
    Consider your knowledge of installing air conditioners. Ideally, the unit will be quick and easy to set up by connecting to your RV’s roof. The air conditioner’s weight and size will also play a role in installation since a heavier unit will require more manpower and tools to attach to your RV.

RV Air Conditioner FAQs

How often should you clean your filters?

All RV air conditioners are fitted with air filters, which we suggest need cleaning every two weeks. For most people, this is after each trip in the RV. Consider cleaning your air conditioner’s filter more often if you own pets, where the pet hair can cause airflow blockages. The cleaner the filter, the cleaner the air, so don’t forget to replace them if they become worn, too.

Which is best for air flow, non-ducted or duct?

During your search, you’ll come across non-ducted and duct air conditioner units. Non-ducted units blow out air from the bottom of the unit via one panel. This is perfect for cooling one area of the RV. However, if you’re looking to evenly distribute air flow on a larger surface area, opt for a duct air conditioner, which is designed with multiple panels.
