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.

There are two likely scenarios when it comes to installation.

Scenario one

Let’s face it: Installation of an RV air conditioner isn’t going to be most people’s idea of a good time. Lugging a near-hundred-pound piece of machinery up to your RVs roof may be beyond capabilities of many RVers. Plus, the instructions feel like you would need a technical degree (along with maybe a stiff drink or two) to understand it.In this scenario, you would need some help. Fortunately, for a fee, you can find many retailers and RV repair shops willing to install your new unit for you. However, expect to pay a few hundred dollars for the service.

Scenario two

You eat and crush cans of spinach for fun. Therefore, hauling an RV air conditioning unit up to your RV roof isn’t an issue. Plus, you enjoy reading and critiquing appliance manuals for kicks. The phrase DIY (do it yourself) isn’t just tattooed on your body. It is a birthmark. In other words, you feel supremely confident that you can install your RV air conditioner without professional help.

What’s the moral of these two stories?

If you believe that you can install your new RV air conditioner on your own, then you are probably correct. However, as for how easy it will be, that’s something that may depend on your experience and physical capabilities. That said, there is certainly no shame in getting professional help if you are unsure. This may save you hundreds of dollars down the road should you make a mistake during installation.

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?

Is your air conditioner blowing weaker than usual or warm air? In some cases, this could mean you need to replace your capacitors. But in others, it means your air conditioner’s on its last legs.

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

In certain situations, this could mean that your motor fan needs replacement. However, once again, it could also mean that you are overdue for a new cold maker.

Question three: Has your RV air conditioner started leaking?

There’s nothing quite like stepping in a cold or warm puddle of water barefoot in the middle of the night (especially if you have pets). The explanation could be as simple as a leaky gasket that needs replacing. When this happens, the bolts attach to the AC unit may loosen and start to rust.Again, however, this could also point to a more significant issue where it may be more cost-efficient to replace your air conditioner.

Question four: Is your RV air conditioner too loud?

The source of this problem could be something caught up in the motor or some other fixable issue. That said, it could also mean that your air conditioner’s ready to go out with either a bang or whimper.
