After which, you can haul it up to the roof. But other than that, the installation is super easy although there are no installation instructions provided.

Coleman produces one of the best RV air conditioners, specifically the Mach 15 model. At BTU 15,000, the cooling strength is just right. It is not too cold like 20,000 BTU and neither is it too weak like 10,000. 


This trailer AC unit delivers cool air at high volumes with good coverage of 320 CFM (cubic feet per minute). This RV air conditioner cools your RV unit in minutes. This is because it uses large evaporators and condenser coils which helps the cooler easily dissipate heat. This allows you to maximize the time you spend on the RV. 


This RV rooftop AC is generally very compatible with most RVs with ducted AC systems. It fits well in a 14X14 RV roof vent hold, which is commonly found in RVs.

The cool part of this roof air conditioner is it has dual functionality. You need to purchase the heater as an add-on. On cold days, you can turn on the heating function. But do not expect too much as it produces only 5600 BTUs. This means you can utilize this unit for most seasons in your travels.

If you do not want to deal with the installation of a rooftop AC, we have added a portable air conditioner as an option for an RV air conditioner.


It is super easy to use, just plug and play. If you have a pop-up camper where heavy rooftop AC is not suitable, then you can consider this option as well.


The price is a steal for 3 functions which you can use separately. It has the cooling mode, the dehumidifying mode, and the fan mode. The dehumidifier works great to pull the moisture from the air. 


This makes your RV more comfortable to sleep at night. The portable outdoor air conditioner cools very quickly with its 8000 BTU cooling power and it works beautifully in spaces up to 215+ sq. ft. There is an exhaust hose installation that comes together with the unit. This helps pull out the heat from the RV.  


Its design would require you to run inside the RV. There are wheels and finger grips so you can roll it or pick it up to move it. This makes it portable to move the unit within the RV easily and store it into the compartment when not needed. 


It comes with a remote control which is a great addition. It allows easy temperature adjustments. There is no need to get up to turn it on or off. The window vent kit is sturdy. The vent swings up and down to provide great airflow through your RV. 



Although it has an operating noise level of only 55 57 dB, some users have feedback that it is a little loud. But this is the same as most portable air conditioners. 



  • 3-in-1 functionality: cool, dry, and fan
  • shows the current room temperature just plugged in and not on
  • Noisy
  • Window exhaust installation kit could be improved

Portable RV air conditioners are smaller and may contain many more features compared to rooftop models. Add-on features can come in the form of a dehumidifier, HEPA filter, or even as a heater for cold days. The drawback is that it may take storage space in your RV.


Rooftop RV air conditioners can circulate the air throughout your RV more efficiently. It requires you to have a roof vent else you will need to cut through the roof to install the unit. 

At the same time, a unit with a low profile and an aerodynamic design will help reduce drag and increase the performance of your RV. It is also easier to park in places with low roofs.

If your motorhome is under 32 feet, 1 unit of AC is sufficient. Otherwise, you may need extra AC units.

Ducted Versus Non-ducted


If you have multiple rooms within your RV, a ducted unit is a solution. It helps distributes cold air evenly throughout your motorhome. On the other hand, ductless air conditioners just blow cold air into a single space. 


If you are able to sleep with white noise in the background, then this should not be a concern for you. Most air conditioners are between 40 – 60-decibel range, equal to a household refrigerator. You may want to avoid those that exceed this range. 

Cooling capacity

To keep your air-conditioned tent cool, your air conditioner needs to run on a generator, a campsite with grid power, or battery power. Generally, battery-operated air conditioners do not work efficiently especially for long durations. 


The average AC unit has is 13500 BTU power. To cool a large RV, it requires to have at least 15000 BTU (British Thermal Unit). BTU is the standard unit of measure to measure the cooling power. Any less BTU capacity will not provide you relief through the day or night. 



Just to give an estimate of how much wattage you need, a 13500 BTU requires roughly 2750 starting watts and 1250 running watts. On the other hand, a 15000 BTU, needs about 3500 starting watts and 1500 running watts.
