When shopping for the best RV air conditioner, you will find that two brands sit atop the RV air conditioning market. Dometic and Coleman-Mach are the two top brands that offer the best RV air conditioner models money can buy. Here are a few considerations you will need to take into account before making a final decision.

Shape matters

The best RV air conditioner units will offer a sleek, aerodynamic design. This detail is vital as your unit will need to resist wind drag that can slow your vehicle down. This problem becomes more pronounced in severe weather, and it can also harm fuel efficiency.

Watch Those BTUs

British Thermal Units (BTUs) may very well be the central factor you need to think about when deciding on the best RV air conditioner. BTU represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. One BTU equates to about 1055 joules (derived unit of energy).

Here's a chart explaining the recommended BTU output for different RV sizes.

Determining how many BTUs your unit will output can help you figure out how well your new RV air conditioner will cool your space. For example, If you are frequently traveling in hot and humid locales, then you will want a unit with no less than 13,500 BTUs.

Some RVs only have one central air conditioning unit inside them. But, while this setup may work most of the time, it can be a real pain to cool the entire RV. This holds especially true if your RV is set up on asphalt or has metal panels. Keep in mind; a larger RV may require an air conditioning unit with at least 18,000 BTUs or more to cool your rig. In some cases, two units may be necessary.

Installation

What's the moral of these two stories?

Do you need really need a new RV air conditioner?

This question is, of course, only one you can accurately answer. In some cases, your current unit may already be the best RV air conditioner for your needs. It may just need a little maintenance to return to its full glory. However, in other situations, it may be time to consider buying a new RV air conditioner.

Here are a few questions to help you determine if a new RV air conditioner is needed. If the answer to any of these questions is yes, then it may be time for an upgrade.

Question one: Does it take your RV air conditioner a while to start?

Question two: Does your RV air conditioner only operate when set to specific speeds?

Question three: Has your RV air conditioner started leaking?

Question four: Is your RV air conditioner too loud?
