Some Additional Information About RV AC Units

Other than the above-mentioned points, you must know these things for making an ideal purchase-

  • BTU (British Thermal Unit)

Depending on the type of vehicle, you have to consider the BTU of RV air conditioner. Higher the value of BTU and it provides a greater cooling effect on demand.

If you prefer visiting warmer areas, then it is a much important factor. For an effective cooling environment, you must-have the higher value of the BTU.

  • Aerodynamics

Large air conditioners may produce some drag to the RV while installing. And, there is a high chance that this drag will increase over time.

If the AC unit has less aerodynamic capacity in its design, it also needs more power to operate. And, this reduces the efficiency of the AC system.

You should buy one with good aerodynamic properties for effective cooling.

  • Height Clearance

Another important factor to consider is height clearance after installation.

The idea of providing less clearance may lead to damage to the structural objects. How? This especially happens when you store the RV in your garage. And, the upper part may strike to the lintel or shutter.

You should provide appropriate clearance such that your RV can move freely.

Let’s start with the maintenance procedure of your existing trailer air conditioner-

Troubleshooting RV Air Conditioner Units

Several DIY (Do-It-Yourself) methods are possible for troubleshooting and maintaining your rooftop AC unit. If you love to stay outdoors (especially camping), you have to know the majority of the things.

During the hottest time of the year, it is imperative to keep the units in good condition for attaining the maximum efficiency. In this context, lubricating the motor can enhance its performance and may also extend its life.

Many brands of AC units are present in the market. Thankfully, they all work with similar principle and have almost the same design.

Before maintaining or repairing the roof mounted air conditioning units, you must have to familiar with its different components-

  • Compressor

It circulates the gas through the condenser. And then, it passes the same through the evaporator coils to repeat the cycle.

  • Condenser

It is used to cool down the incoming refrigerant vapor and converts it into liquid.

  • Evaporator

The evaporator coil absorbs the heat from the refrigerant and allows it to repeat the cycle in its usual state.

  • Fan Motor

An AC fan motor combines with condensing coil for distributing air throughout the enclosed space. It includes blower fan for doing the same.

How To Maintain Carrier RV Air Conditioning System?

Some of the common problems faced by the users include-

  • Capacitor

In most of the cases, you have to troubleshoot the compressor and fan motor. And, both these units have a common capacitor.

If it doesn’t work, neither the fan motor nor AC compressor will start. You can buy a new one and replace it by paying a little amount of money.

  • AC Shroud/Covering

Over time, you can notice cracks and bad spots on the top of the Shroud. If you maintain it, there will be no troubles of replacing the same.

For cleaning it, you have to remove Shroud using a screwdriver. Open the screws or nuts carefully and wipe the unit with a cloth. Now, place it and tight the same using screws.

If you find the Shroud has cracked, you can use glue on its plastic material for repairing.

In case, glue doesn’t work. You have to purchase a new one from the market.

  • Fan Motor

Once you open the AC covering, you are accessible to fan motor. You can inspect it for repairing or maintenance requirements.

If you find your motor seems to start slowly, you have to do the following process.

At first, turn off your device and unplug it from the power source. Clean the debris and provide some machine oil to the bearings. Rotate the fan using hand and it should spin easily.

Now, plug in the unit and turn it on. If everything is fine with the fan, it’ll run at its ideal speed.

Or else, you have to replace it with a new one.

  • Condenser Fins And Evaporator Coils

For maintaining the efficiency of the roof mounted air conditioners, you have to clean these AC parts.

In most of the cases, dirt and debris clog the fins and coils. You have to use good spray or foaming cleaner to remove them.

No doubt, this will clear out the debris. But you have to be careful so that fins won’t bend.

  • Compressor

The labor involved in AC compressor maintenance and repairing is higher than any other parts.

And, it is also considered as the most difficult part for the novice users. It is advised to simply replace the compressor instead of its repairing.

This is because the price of a compressor is almost equal to the entire housing. In other words, spending dollars for new compressor plus extra amount will provide you with a new AC.

If you are looking for an alternative solution, then you have to find a used compressor. This will cost less and the most effective option.

(Be sure you have read the user manuals before operating a new or replaced AC for camper!)


For protecting your roof mounted ac units from wind, rain and other flying debris, you should provide plastic cover. Or else, it may get damaged due to chemical interactions over time.

Some of the damaging objects include stuck by low hanging tree-branches, physical trauma, UV radiation and more.

In case, you need to purchase replacement parts or the whole unit. Consider the above-mentioned points for making an ideal choice.
