How to Install a Window Air Conditioner in a Pop Up Camper

No one wants to be camping in the summer heat. Luckily, if you have a pop-up camper, installing an air conditioner is easy! This blog post will walk you through all of the steps needed to install your window AC unit. First things first, make sure that there’s enough room for the AC unit before drilling any holes. After measuring and making sure there’s enough space for it, drill pilot holes into each corner (just like when assembling furniture).

Next, attach L-brackets to the corners with screws or nails so that they’re tight against the framing on either side of them. Finally, fasten two brackets at right angles to each other at both ends of where your AC will go by screwing them into the corners. This will make it easier to screw the AC itself into place. The first step in getting started with how to install a window air conditioner in a pop up camper.

Step by Step Guide on How to Install a Window Air Conditioner in a Pop Up Camper

Step One: Make Sure the Unit Fits in the Window

The first thing that needs to be checked is whether or not the air conditioner fits into the opening that has been cut for it in the side of your pop-up camper. If it’s too big, then many different things can be done to help resolve this issue.

The easiest solution would be to chisel off just enough of the roof to fit the air conditioner. Another option would be to purchase an air conditioner sleeve,  which is basically a large covering for your air conditioning unit.

Step Two: Mark the Opening on the Roof of Your Camper

After you have made sure that the air conditioning unit will fit through the hole in the side of your camper,  the best thing to do would be to mark a square around where you want the unit installed.

Now, some people find it easier first to cut the hole in the wall of their camper and then install the air conditioner once it is up there. If you feel like this would be less complicated for you to do, go ahead and try that instead.

Step Three: Cut Out Sections of Ceiling

Once you have marked where on the ceiling you need to cut, the next thing to do is get your jigsaw and start cutting along those guidelines.

It would be best if you continued making cuts until there were no pieces left that you could cut out without them falling into the camper itself below the ceiling panel. At this point, use a brush or vacuum cleaner to clean any debris that has fallen inside the camper.

Step Four: Install the Air Conditioner Bracket

Now, you are ready to install your air conditioning bracket. This is probably the easiest step in this entire process because all you have to do is screw it into place with some screws that match up with your pop-up camper ceiling paneling.

This will hold the air conditioner up in place and allow you to work on getting it connected to electricity and any mounting brackets that might be necessary for its stability.

Step Five: Mount the Air Conditioner to the Ceiling Panel

If your air conditioning unit came with mounting brackets that are attached via screws, then it will simply be a matter of connecting them directly into the ceiling panel itself.

Once these are securely in place, you can use some additional pieces of paneling to cover up where the screws are coming through or simply make sure that your mounting brackets are placed in an area where they won’t be seen.

Step Six: Get the Electrical Work Done

Having everything else ready to go is excellent, but if you don’t have electricity running into your camper once the air conditioner has been mounted to the ceiling, then you won’t be able to use it. So this is the time when you need to turn your attention toward getting electricity run into your camper for the window unit air conditioner.

This can be done by having an electrician come out and do all of the wirings in that area, or if you are comfortable with electrical work yourself, you may be able to get the job done yourself. Once this is complete, you can turn on your unit and begin enjoying it!

Step Seven: Seal the Cutouts

Even though you may have vacuumed up all of the dust and debris that fell during this installation process, there is still a chance for it to get into your camper. To prevent this from happening, just use some caulk or any kind of sealant around the area where you cut out sections of the ceiling, and you will be good to go.

Now you have successfully installed a window air conditioner in your pop-up camper! This will allow you to continue enjoying camping even on the hottest of days without worrying about what is happening inside of your camper.

Will a Portable Ac Work in a Camper?

The answer to this question is definitely yes. Portable air conditioners are designed to work in a wide array of spaces, from rooms to cars. In most cases, you will need to have the window unit installed into your home or vehicle by a licensed HVAC professional if you live in a strict housing association or dormitory.

In some cases, however, portable air conditioners can be installed in the right spaces by the user, or it can be done with help from someone who is familiar with air conditioners. The key to this installation, though, is finding the appropriate size unit for your camper and having someone who knows how to install an air conditioner properly do the job.

Frequently Asked Questions

Will a Portable Ac Work in a Camper?

If you are looking for a portable AC to cool your camper in the summer, we recommend using a window unit AC.

A window unit AC is small and lightweight but can provide plenty of cooling power for your camper or RV. It is perfect for those who want to sleep well at night without the noise of an engine-driven fan that could wake them up.

Can You Put a Window Unit in a Camper?

If you have a window unit that needs to be in a camper, the best option is to use an air conditioner.

A window unit is not ideal for this purpose because it doesn’t have enough power to cool the whole area and has nowhere near the cooling capacity of an AC.

What Size Breaker Do I Need for a Window Air Conditioner?

A few factors need to be considered when selecting the size of breaker required for your window air conditioner.

The first is how many amps your air conditioner will draw and how many watts it will consume. The next factor is what voltage you want your circuit to be at. Finally, you need to know the total amount of electrical equipment in your home that needs power from this circuit, so take into account any lighting or appliances that will also require power on this circuit.

If you have a window air conditioner and are unsure what size breaker you need, call an electrician who can help with this issue.

Can You Use an Extension Cord for a Window Air Conditioner?

No, it is not possible to use an extension cord for a window air conditioner. An extension cord can be used with a portable air conditioner but not a window air conditioner. A window air conditioner uses its power source, so you cannot plug an extension cord into the unit.

Does a Window Air Conditioner Need a Dedicated Circuit?

A window air conditioner does not need a dedicated circuit. Instead, they can be plugged into any electrical outlet and draw power from the same circuit as other appliances in your home.

There Are Some Precautions to Keep in Mind When Using an Air Conditioner:

  1. If you live in a small space, make sure you have at least three feet of free space on all sides of the unit to avoid overloading the circuit.
  2. Keep the windows closed while it is running so that the room doesn’t get too hot or cold.
