Step-by-Step Installation Guide

Step 1: Prepare your RV Roof


Before you start removing the old air conditioner, you need to first prepare your RV roof to prevent it from getting scratches as you work on it. To protect your RV roof, you can use old blankets or towels. Just use them to cover the area around your air conditioner unit.

If they won’t stay put, you can use masking tape to hold the blankets or towels in place. Make sure that they are secure in place because one small wrong move can scratch the paint of your RV roof.

Step 2: Remove the Air Conditioner’s Shroud


The next step in the process after making sure that your RV roof is well protected is removing the air conditioner’s shroud. This part is what acts as a shield and covers the air conditioner’s interior parts. Be careful in removing this part as you will need it again for sure.

While it may depend on your air conditioner’s model, most shrouds can be removed with the use of a screwdriver. All you need to do is to locate the bolts or screws and undo them one by one.

Make sure to put the bolts & screws in a place where they won’t get lost since you will be using them later on. Carefully remove the shroud and set it aside.

Step 3: Remove the Air Conditioner from the RV’s Roof


Once you’ve removed the shroud that covers the AC’s interior, you should now be able to see the fasteners that are holding the air conditioner to your RV’s roof.

Most RV air conditioners have a metal bracket below the unit on the RV roof’s underside and a gasket at the top of the RV roof and just beneath the AC itself. They are held together by bolts and screws that compress the AC unit to the gasket.

To remove the air conditioner from your RV roof, just remove the fasteners or the screws and bolts that hold the AC to the gasket. After that, check all the electrical connections of your AC unit. If it uses a harness-style connector, simply unsnap it. Otherwise, you need to use a pair of cutters to cut out three wires.

Before removing your air conditioner, make sure that the power is disconnected. Then, carefully slide out the air conditioner.

Step 4: Get rid of the Old Air Conditioner Gasket


Now that the air conditioner is removed, you need to carefully pull out the AC’s gasket from your RV roof or cut it out with the use of the utility knife. Check the area for any residue that’s left. If there is any, you can remove it with the use of a heat gun and a putty knife.

Once you are sure that there isn’t any residue left, clean the area to prepare for installing the new gasket. You can use rubbing alcohol and a soft cloth to wipe the area.

Step 5: Install the New Gasket and Put Back the Air Conditioner


Next, install the new gasket by placing it over the RV roof’s opening. Make sure that it is placed securely before taking your AC unit and placing it on top of the new gasket. Align everything properly before you reattach the air conditioner.

After installing the AC unit, reconnect all of the electrical wiring that you removed earlier. Once you are done, you can reattach the shroud back by screwing it in its place.

Step 6: Test your Unit and Clean Up


The final step in this process is to test if your air conditioner is working well. You may experience some problems with your electrical wiring, so make sure that all is well. Once you’ve done all the final checks, clean up the towels and blankets you used to cover your RV roof and return all the tools to their proper place.


For rig owners, knowing how to install RV air conditioner gasket is helpful knowledge that can help them save money and prevent further problems with their AC.
