Buying an RV is a big investment and will potentially remain with you for years, therefore, you must bedeck it with the best air conditioner so that complies with every sort of condition. We will discuss everything you must know regarding air conditioners for RV.
Considerations Before Buying Air Conditioner For RV (Buying Guide)
1. The size of the vehicle: Class A RVs are about 45 feet and require two units powerful enough to cool up the entire area while Class B RVs are the smallest and you can rely on a single AC for it. The size of the RV will also decide the power you need on your air conditioner. BTU which is short of British Thermal Unit is used to indicate the power of ACs and 1 Btu is equal to the amount of energy needed to raise the temperature of 1 pound of water by 1 degree; reverse it for ACs, it would be the energy needed to decrease the temperature.
2. Clearance height: This factor only comes in to play when buying rooftop air conditioners because they are installed over the roof and may cause problems when passing tunnels, or underpasses. It is best to go for low-profile and streamlined AC units.
3. Do you have drain spaces: Window and portable air conditioners would need separate outlets for their drainage and you must be knowledgeable as to which window is suitable for the installation of a window AC or as drain outlet.
Considerations For The Installation
1. Most of the time, there is a dedicated roof vent for the installation of a rooftop AC. In case there isn’t, you must consider the following locations:
For motorhomes, it should be installed within 2.7m of the driver’s cabin.
For travel trailers, the location should be near the door slightly forward of the vehicle’s centerline.
For a truck with a camper, it must be in the range of 1.2-1.5m from the backside of the camper to ensure maximum cooling.
2. Installing a window air conditioner may be the most time-consuming. Firstly, with the aid of a helper, position your unit in the window to keep it balanced and screw it with the flanges above and below. More than half of the unit should be outside. Secondly, secure the unit with any of the necessary fittings like the L-shaped clips and connect the bottom and top sash frames. Then, look for any gaps in the window and seal them with foam and after it, install the drain piping. Drill a hole to route the power cables and voila, you are done! Though, its not that simple and we recommend a professional for doing it.

Repair Is Important If You Want A Long Life For Your AC Unit
Every machine in the world is entitled to repair because running and environmental conditions affect their interior, for example, a car filter is meant to get caught up in dust after three weeks of use and an AC’s compressor is likely to get a gas refilling after 8 months. Repairing your RV’s air conditioner timely will elongate its life and only then, will you get full advantage of your investment.
Know the parts:
It is important to know what your air conditioner is made up of. Many people know what the outer buttons do and how to clean the filter but fewer are well-informed about the internal structure which includes the evaporator, compressor, and motor.
How to go about maintenance:
Cleaning of the filter is the most obvious maintenance procedure which can be performed. They are either present on the front side of the rooftop air conditioners or at the sides or backside of the window or portable AC. You can remove them easily and wash it with soap or detergent before drying it in indirect sunlight. Make sure that it is properly dried before inserting it back. A dirty filter restricts the flow of air through the system and causes overheating. It also puts pressure on the motor and causes it to work harder which leads to more power consumption.
For the more extensive cleaning, you need to sink inside the unit and for that, unscrewing of the shroud is required. Condenser coils and evaporator tend to be the favorite spots for the accumulation of dirt. They should be first cleaned by an air blower and then with a clean, dry cloth. Keeping these parts unattended for a longer span of time would largely reduce the cooling effect because after all. It’s the compressor that raises the pressure of the refrigerant to create that pressure difference which is required for the transfer of the refrigerant.
Troubleshooting: Common RV Air Conditioner’s Problems And Their Solutions
1. The air conditioner is not turning on: It can happen due to two minor issues. Firstly, the batteries in your remote may have depleted. Change them and get new ones. Secondly, there may be an issue with the power supply of the AC. Check whether the cable is damaged from some point or not properly plugged in.
2. Air conditioner giving a bad smell: It is frustrating to smell bad air when you turn on the AC but it could happen due to various reasons. The first one is the unclean filter, condenser or evaporator. The solution lies in keeping them clean because they wouldn’t only give bad smell if left dirty but will also nourish the growth of bacteria. The second reason could be water collected in the unit. It produces hydrogen sulfide which has that pungent rotten eggs smell. Check for this time and never have standing water because it can also give birth to mosquitoes.
3. AC giving hot air: There is a problem with the thermostat. Check for the temperature set on the remote as the first solution. You could have mistakenly set it to a high temperature or fan mode which means the compressor is simply shut off. A more technical technique, if the first one fails, is to disconnect the two wires leading to the thermostat and attach them together, bypassing the thermostat completely. If the unit switches on, it is surely a broken thermostat because the circuit is broken. Get an electrician to fix it up for you.
4. The unit is leaking: We are talking about leakage from the back or front side of the air conditioner and not the drain hose because the drain hose is meant to expel out water. In extreme temperatures, leakage is likely because of the condensation occurring underside the condenser as hot or humid weather puts extra pressure on the compressor to work. But if the dripping continues, here are some troubleshooting mechanisms.
Check for any blockage in the drainpipe because if there is, the water would collect in the evaporator unit and expel all the way out of the drain tray, through the sides of the air conditioner. There could also be an issue with the drain tray. If it is broken, not all of the water would find its way to the drain pipe and will spill out from the sides of the unit. Moreover, blocked air filters can also contribute to this leakage. If they are crammed with dirt, evaporator coils may freeze and extra water would spill from the sides of the drain tray.
5. Noisy AC: Rooftop and window air conditioners are more prone to this problem because they have a part of them outside the vehicle. Anything from dirt, mud or debris can get into the unit and account for rumbling or humming noise. If there is a rattling noise other than the normal one, the condenser should be inspected for any signs of foreign particles like tiny leaves and get rid of them. Blow air through an air blower if you can arrange for it.
If there is a whistling noise, it is mainly due to the leaking refrigerant. Upon finding out, ring a professional and take his help.
If the nature of the noise resembles a moaning, probably the motor has started to worn out. Look for a new motor; you can either purchase it online but one must be an expert to choose the correct model or go to the market and buy a replacement which is a much safer option.
Tips For Maintaining RV Air Conditioner
If you are not using your air conditioner, it is an intelligent practice to open the roof vent and let the moisture which may be settled within the unit to evaporate.
Don’t always operate your air conditioner on low temperatures because doing so will age up to the unit quickly. Rather, opt for a temperature of 24-26degree Celsius every now and then. The other thing you can do is to turn on the “fan” mode because this will adjust the temperature to the required temperature and then give off cool air.
The fan rotates the entire time an air conditioner is on to circulate the air hence it is prone to get worn out, therefore, you need to keep it well-oiled.
- Keep an eye on the time each time your AC takes to cool up the RV. If it continues to gradually take more time than previously, your compressor or evaporator is aging and needs cleaning or repairing. Do this at least twice a year to be well informed.
- What are some good RV AC brands?
Not all brands are trustworthy and therefore, we have only included recognizable and respected brands in our articles.
Airxcel: It was founded in 1991, and quickly became one of the leading manufacturers of climate control products including air conditioners, heaters, furnaces and ventilation systems.

What should be the power of the air conditioner for my RV?
It depends on the size of the RV you own. We would script down the rule of thumb however it is subjected to variations depending on the outdoor weather conditions, the manufacturing company of the AC and the amount of heat-emitting devices inside your RV like a refrigerator or vacuum cleaner. To cool small areas of 150-250 sq. feet, 8000 Btu are sufficient, to cool areas of 300-400 sq. feet, you would want ACs of 10000 Btu., for cooling larger areas till 700 sq. feet which is not usually the case with RVs, you would require 12000 Btu units and a larger one for more area.
- What is EER?
It is the ratio which is calculated by dividing the cooling output of an air conditioner (in Btu) by the energy consumption in watt-hours. Abbreviated for Energy Efficiency Ratio, it gives an idea about how efficient your HVAC system is. Simply, the higher the EER value, the more efficient your AC is. 11-12.5 ratings are regarded as good EER ratings. You should always look to but the air conditioner which has a high EER value because it carries significant advantages.
Higher efficiency contributes to low power consumption and ultimately to less electricity bill. Secondly, most of the high-EER systems are much durable, reliable and offer extended levels of cooling due to the incorporation of cutting0edge technologies. Lastly, they are constructed with environmental-friendly parts and thus do not emit harmful gases or compounds.
- How do we charge/refill RV AC?
Like domestic air conditioners, you need to recharge the unit with fresh refrigerant after a fixed time period because they will run out eventually. Follow an easy scheme of steps to insert the refrigerant accurately and safely.
Firstly, purchase the right refrigerant. The details of the accurate one are narrated on the manual or side of the air conditioner.
Secondly, turn off the power supply to the unit.
Thirdly, remove the screws that attach the shroud with the body in case of a rooftop AC, unscrew the backside of the unit in case of a window or portable ones and lift the lid. Be careful that nothing gets damaged. Utilize a screwdriver or a tester for this step.
Fourthly, locate the refrigerant gauge and unscrew the port. After this, add the recommended amount of refrigerant steadily. Check for the temperature difference between the air inside the RV and the unit. It should be greater than 20 degrees. Screw back everything and turn on the power to the unit to discover the change in the cooling effect. (Hoping for better results)
