Simple Installation

Because your RV is likely already prepped and pre-wired for an AC unit, installation is simple. Most AC units are designed to fit an opening that measures 14-1/4" x 14-1/4". Depending on your roof setup, you may need to do minimal alterations. If the opening is larger than 14-3/8" x 14-3/8", you will need to install spacers between the sides of the unit and the opening's edges. If the opening is smaller than 14-1/8" x 14-1/8", you will need to enlarge the hole to fit the unit snugly inside the opening.

On the bottom of the AC, there's a thick, collapsible gasket with 6 noise-reducing foam pads. This provides support between the RV roof and AC and seals the opening to prevent water and outside air from leaking in. Because of this, the use of fresh sealant isn't needed. Once installed, the hard plastic cover on the AC can easily be removed for maintenance and cleaning.

In order to fully complete installation, this AC needs to be paired with a 2025 or newer Advent Air air distribution box and thermostat.

Additional Accessories

Additional accessories can be purchased separately to improve the performance of your Advent Air AC unit. The start capacitor (ACMSCKIT) improves the performance of your AC by using stored energy to jumpstart it. And the electric heat strip (ADV34QR) removes the chill on cold or frosty mornings in your RV, ensuring you stay comfortable. Please note that the heat strip will only work on Advent Air AC units.

Advent Air Warranty Coverage

2-Year limited warranty covers defective units when installed correctly on approved applications. The warranty does not cover units installed incorrectly. To ensure air conditioner is installed correctly, please see the questionnaire pdf below. A filled-out questionnaire is required for warranty coverage.

If you are not comfortable using a voltmeter (or removing the charge from the start capacitor), you'll want to make a service appointment with your local RV dealer to verify the installation. Print the pdfs below (warranty- questionnaire, warranty dealer information) and take them along with the RV to your local dealer. ASA does compensate dealers for warranty work as outlined in the dealer information pdf. You may be charged by the dealer for time spent investigating the installation.
