How to Install an RV Air Conditioner
Of course, purchasing an A/C for your camper and stocking up on accessories is only half the battle. The next step is the RV air conditioner installation. Luckily, it's pretty simple to install RV air conditioner units and can be done with basic hand tools.
Removing the Old Air Conditioner
(1) Begin by turning off the air conditioner and unplugging your RV from all power sources.
(2) Put down blankets to protect the roof surrounding the A/C.
(3) Carefully climb onto the roof, remove the screws around the shroud of your old unit, and pull the shroud away.
(4) Using a putty knife, carefully scrape away any old adhesive.
(5) Head back inside and remove the ceiling assembly from the ceiling.
(6) Remove the four long bolts that hold the A/C in place, and the metal retaining flange should drop down.
(7) At this point, you should be able to disconnect the A/C wiring and unscrew or loosen the ducting from the unit.
(8) Go back onto the roof and separate the old unit from the roof using the putty knife if necessary.
(9) Carefully lift the old unit out of the duct hole and clean the area well, making sure no adhesive or putty is left behind.
RV Air Conditioner Installation
(1) To install the new unit, remove the shroud and place the unit over the duct hole, making sure the rubber gasket lines up with the hole perfectly.
(2) Head back inside and connect the wiring and ducting.
(3) Install the metal flange, ensuring it is turned the correct way before placing and tightening the four long bolts that hold the unit in place.
(4) Finish by installing the ceiling assembly and replacing the shroud.
Be sure to check the manufacturer's instructions before installing your new unit, because each unit is slightly different.
