RV Air Conditioner Tips and Simple Repairs

RV air conditioner repairs are necessary, especially when cooling is not practical.

The first and foremost thing you need to know is that the conditioning systems function on the same principle: extracting heat from the inside.

If you need tips on troubleshooting, this post will provide you with some valuable ones and “how to instructions” that will help you keep your RV cool and comfortable with the Air Conditioner.

How does an air conditioning system work?

The RV AC unit extracts heat from the interior and transforms it from liquid to vapor, thus cooling the air.

It uses a vent fan to blow it through an evaporator, transferring the heat into the cooling agent. The principle here is similar to how fridges function.

Once the AC unit takes the heat from the room, the cooling process starts.

RV air conditioners include a compressor and a cooling system. The latter is used to turn the liquid into a gas and relocate warmth. Inside the RV, a blower moves the air through a collection of tubes and fins called the evaporator.

Entering the evaporator, the liquid vaporizes, absorbing warmth from the motorhomes inside.

The compressor utilizes pressure to the gas as it  moves outside right into the condenser an extra collection of tubes and fins.

The blower relocates outside air via the fins, which launch heat, and the gas goes back to a fluid state.

Air conditioning systems are limited in RVs due to the intake system.

Instead of having the ability to generate cold air to your preference, they have to process the heat in the cabin to a lower level which means the fact that they will certainly depend upon the temperature level that is being dealt with will undoubtedly affect how cold the air is inside your cabin.

How to turn the RV air conditioner unit on?

Whether on the RV rooftop air conditioner or in the cellar area, AC units function on the same concept. Firstly, ensure you have sufficient power originating from a generator or are plugged into a 30 or 50 amp electrical outlet. To make the AC operate to cool air down inside your camper, it should have a consistent power resource.

There are two knobs you will miss on the surface of the interior RV AC unit to get it going. If your generator is up and running, the AC begins to start controlling the temperature in your RV.

Simple Maintenance Tips

1- Clean Your Filter

To ensure that the air conditioning capacity of your RV AC unit is efficient, regular maintenance needs to be done. Firstly you need to ensure that the AC’s filter is clean.

2- Remove the Filter:

Turn off the AC unit and remove its safety cover. To find ways to remove the air filter from your AC unit, refer to the Air Conditioner user manual.

Remember that you should not turn your conditioner on without the filter.

Unfiltered air will get into your RV, and particles will probably damage the unit.

3- Vacuum the Filter:

Utilize a vacuum at a medium or low mode to dispose of the dust and grime on the surface of the filter. Make sure not to press the filter too hard in case of breaking or denting it.

Some dust is always persistent.

You don’t have to get all the dust off, but try to clean it up.

4- Wash the Filter:

If vacuuming is not sufficient, then you may wash it.  Prepare a container with lukewarm water with mild detergent.

Mix the water with the detergent for better cleanup. 

If this is conducted in the RV shower, you may use the showerhead to spray and wash the filter.

5- Deal with Bacteria :

After the filter is cleaned, it is time for you to sterilize it and mix water with vinegar with the same amount.

Apply the solution in a spray bottle and spray both sides of the filter. 

Place the filter around 10 mins before washing it with running water.

When an RV air conditioner doesn’t keep the RV cool, here are some tips for Common Problems.

IT’S TOO WARM. While the AC system aims to cool the temperature inside your RV, if your RV is in a scorching environment, your air conditioner may not function well.

This frequently happens in more giant gears that may require an additional domestic air conditioning unit to cool down the whole Motorhome, like a mobile air conditioner device. 

AGE. We all get old, and so does your RV air conditioning unit, mainly after a long period of use.

DIRTY ELEMENTS. In one way or another, the majority of us take a trip down the unpaved road. Even if you do not, dirt, dust, and other contaminants accumulate on the AC unit’s elements.

Pay specific attention to the AC unit’s air fans, coils, and filters.

The contaminants can significantly reduce your AC’s efficiency.

PRO RECOMMENDATION. Suppose you’re maintaining your Air Conditioner system clean, yet it still does not get to all the places reasonably.

In that case, you would certainly utilize a simple 12V or battery-operated ventilator to distribute the air in your equipment best.

This can not solely boost your comfort; but might take a few of the effort off of your air conditioner, broadening its life.

RV Air Conditioner Repair

Frequently you’re most likely to do even more small troubleshooting and repair work than you assume! A few common issues of rooftop AC units are relatively easy to deal with.

For example, the problem might not be with the AC unit itself but instead with the thermostat in many cases.

The unit can be working entirely and ready to cool your camper; however, if the thermostat isn’t communicating with it properly, that will cause problems!

For that reason, check the thermostat the moment there’s a problem with your RV heating and cooling. If the thermostat is battery-operated, it might be time to change the battery; if it’s electrically wired, the problem may be local instead of within the roof air conditioner.

Another super-common issue? Forgetting to replace the AC filters. It may seem like a little point, but an old, clogged-up filter can keep your unit from cooling down the camper and adequately contaminating the air you’re breathing.

Installing and Replacing RV Air Conditioner System

** Make sure to look at your proprietor’s guidebook before making any modifications to your Recreational Vehicle for basic understanding and support. Contact a qualified RV air conditioner technician if you have any questions like mounting your RV Air Conditioner  **

Once you have a new air conditioner, you need to take steps to put it in place.

First, you need to remove the old air conditioner system.

Turn off the ac unit and shut down the power. Placing coverings around the roof may protect the roofing system.

Then cautiously go up to the Air Conditioner, and unscrew the screws on the cover. Use a blade to get rid of any wax.

Go back to the roof and eliminate the old system from the top.

Eliminate the screws and, afterward, take down the metallic protection flange.

After that, detach the wiring and loosen up the ducting from the AC system.

Go back to the roof and eliminate the old system from the roof.

Raise the old device cautiously out of the air duct opening and cleanly the location, using a putty blade if needed to eliminate any wax.

To install the new system, procedures may differ.

For standard setups, get rid of the cover and put the Air Conditioning device over the void air duct opening, with the gaskets associating the holes.

After that, wire up the AC device to the RV and the ducting inside the RV.

Locate the metallic flange on the system, guaranteeing it follows the appropriate technique before bolting it back on.

Place the ceiling, mount, and also change the cover.

Once again, this is standard installation guidance, as each system is somewhat different.

Don’t hesitate to contact a certified motorhome specialist if you are not clear about installing your system.
