Can Advent Air Low Profile AC Unit Replace Roof Vent
Updated 12/01/2025 | Published 11/10/2025
Question:
Want to replace a roof vent in my trailer with the advent low profile ac unit. It has an actual 14x14 inch opening framed in with aluminum tubing. Will this fit if the opening is not 14.25 as described in listing. Thanks

Hey Allen, the Advent Air Low Profile AC unit part # ADV45SR that you referenced was designed to fit the roof vent opening you have now so it would work great for you. The 14 inch square opening you have is close enough to the 14.25 inch square opening that there would be no issues with it fitting and working great.

Hey Allen, how did the fit turn out with the Advent low profile AC unit in your trailer’s 14-inch opening? Knowing how it worked could help others with the same roof vent size.
