How to Choose the Best Mini Split for RV

When hunting for a mini split, most RV owners opt for the smallest units on the shelf. A 9,000 BTU mini split can cool up to 500 square-feet space, which is more than enough for an RV.

Still, the size of your RV and the capacity aren’t the only factors to consider. To pick the system that will best suit your RV, keep these additional factors in mind. 

1. Placement – Wall-mounted vs. Ceiling cassettes

Mini splits have many installation and placement options, and each has its applications and advantages. Many RV owners prefer wall-mounted units because they come in the widest variety of sizes and configurations. Besides,  wall mounts are also relatively easy to install.

A wall-mounted mini split will require you to drill a 3” hole through the side of your RV. This hole connects the refrigerant lines and connecting wire to the outdoor unit. 

You know you’ve properly installed a wall-mounted indoor unit when it levels against a straight surface. If the sides of your RV have custom high windows or are blocked by shelving or other obstacles, you might want to consider a ceiling mount. 

Ceiling cassettes, as the name implies, are typically installed on the roof of an RV.  The ideal position is behind the decorative grill that lies flush with the surface. They offer a sleek, unobtrusive and clutter-free look. Apart from that,  their position can be crucial in confined RV spaces. 

However, a ceiling cassette will require you to cut a sizable square on the roof of your RV. Only consider this alternative if aesthetics are important enough that you can brave through the installation process. 

2. Operating options: Heating vs. Cooling

Does your RV require just cooling, or do you reckon you will need heating as well? If your area does not get too cold, or you already have a portable heater, you can save some bucks by using a  basic cooling-only mini split. 

Conversely, if you prefer all-climate air conditioning, a unit with both heating and cooling capabilities, otherwise known as a heat pump, is ideal.

3. Energy efficiency

RV mini splits are generally light on the energy budget because of their modest size. However, efficiency varies from one unit to the next. The system that will go easiest on your vehicle’s battery is one with the highest SEER (Seasonal Energy Efficiency Ratio) and EER (Energy Efficiency Ratio) ratings.

SEER measures an air conditioner’s efficiency over a seasonal period, while EER gives efficiency corresponding to a specific operating condition

SEER is the best indicator of a mini split's efficiency

The value of a higher energy rating cannot be understated. Upgrading from a 9 to a 13 SEER unit can reduce total power consumption by as much as 30 percent. Systems that come with an Energy Star rating have a SEER of 25 and above.

4. Installation

Most mini splits are generally not tasking to install. Just make sure to read and follow the installation manual, step by step.  You will only need to have basic tools such as stud finder, wrenches and levels. If you ever get stuck or have any complications, consult an HVAC pro.

  •  DIY features

A decent DIY mini split will have several features for easy and fast installation. Such features include;

  1. Pre-flared and pre-vacuumed copper tubing
  2. A base mount pad for the outdoor compressor
  3. Wall brackets for the indoor unit

The more comprehensive the installation kit, the more expensive the unit will be to buy.

  • Voltage

It is crucial that the voltage rating of your mini split matches that of your RV. Incorrect matching can lead to poor operation, or worse, a fire. RV-friendly mini splits typically run on a 110-120-volt plug. Before buying a unit, make sure that your RV will have enough voltage to support it. 

5. Extra features

If the choices remaining on your list tick all the important boxes, you can break the deadlock by comparing the extra features. Some of these nice-to-have additions include;

  • Smart connectivity 
  • Louver position memory
  • Customizable operating modes
  • Sleep mode
