Adco AC Cover

Worried about your brand new Dometic or Advent AC unit getting dirty or rained on while you're storing your RV in the off season? This cover will protect your RV's AC unit, so it won't fade in the sun or need a good cleaning after a series of storms. When you keep your AC unit covered, you'll extend its lifespan and prevent it from prematurely aging.


The heavy-duty, jersey-backed vinyl material helps insulate your AC units to reduce drafts on cooler days during storage. Reinforced with sealed seams, this cover is weatherproof and tear resistant, so it'll hold up against rain showers, sunny afternoons, and debris such as falling branches.


Securing the Cover onto Your AC Unit


Adco AC Cover Drawstring

You can easily and quickly slip this cover over and around your AC unit and use the parachute drawstring to tightly cinch the cover for a more secure, contoured fit. And the non-abrasive, soft felt interior won't scratch your AC unit if the cover slightly shifts around during windy conditions. Just be sure to remove the cover once you're ready to hit the road again.

    I have an option for you. But when I used the numbers you provided, I got 2 different results. One was the Dometic Brisk II and the second was the Dometic Penguin.

  • Recommended Dometic AC Cover that Measures 40" L x 29" W x 9-1/2" Tall
    I am sorry but we do not have an AC cover with those dimensions. The closest option we have is the Replacement RV Air Conditioner Cover for Penguin and Dometic Air Conditioners item # AT3308046006 which measures 40-1/2" long x 29" wide x 7" tall. If you could give me a part number off of your Dometic AC unit I can try to track down a replacement for it that way. Feel free to email me directly or add it in the comment box below. I hope to hear from you.

  • Air Conditioner Covers and Sewer Vent Cover To Keep Insects Out While In Storage
    Here is a list of the air conditioner storage covers we carry. I have included all the measurements so you can select the correct cover depending on the height of your units as well. 37" long x 26" wide x 13-1/2" tall # 290-3026 43-3/4" long x 29" wide x 14" tall # 290-3023 39" long x 25" wide x 11" tall # 290-3016 41-1/4" long x 22-1/4" wide x 13-1/4" tall # 290-3024 41" long x 25" wide x 9" tall # 290-3025 34" long x 29-1/2" wide x 14-3/4" tall # 290-3021 35" long x 27" wide x 13" tall...

  • Replacement Cover for Model 57915.303 Air Conditioner on 1990 Passport
    Based on my research, the 57915.303 model number you mentioned in your question refers to the Dometic Briskair air conditioner unit. If this is the case, then the Adco Air Conditioner Cover # 290-3021 should fit perfectly. This cover features overall dimensions of 29-1/2 inches wide, 14-3/4 inches tall, and 34 inches long. I have attached a short video demonstration on this cover that you can also take a look at.

  • Storage Cover Recommendation for Dometic 459516.701 AC Unit
    According to my research your Dometic 459516.701 AC unit is the Dometic Brisk Air II model 59516 which means the Adco RV Air Conditioner Cover # 290-3021 is what you're needing. This measures 34" long x 29-1/2" wide x 14-3/4" tall and is backed by a 3-year warranty. Attached is a review video for you to check out.

  • Determining The Correct RV AC Storage Cover For A 1999 Skyline Trailer
    The Camco Vinyl RV Air Conditioner Cover for DuoTherm Models # CAM45263 is 33-3/16" Long x 28" Wide x 15" Tall and is designed to fit Dometic Duo-Therm models 579, 590, and 595. Honestly, I recommend just physically measuring the shroud of your unit to ensure fitment. Each of these covers has a drawstring to tighten it around the unit so the cover being a bit larger wouldn't be an issue. I've listed a few other options we carry below in white and their sizes to help you find the correct...

  • Replacement Cover Recommendation for Duo Therm Air Conditioner
    I recommend going with an Adco cover. We push their covers for the whole RV and get good feedback so I recommend going with their brand. I wasn't able to find what exact Duo Therm you have using what you gave me but here are the covers we have along with the Duo Therm models they fit: Part # 290-3016 Duo Therm Penguin I and II Low Profile CA Series Part # 290-3021 Duo Therm model 57915 Part # 290-3003 Duo Therm: 54608, 54615, 55712, 55715, 55812, 55815, 57008, 57012, 57015, 58925, and...

  • Dimensions Of The Adco RV Air Conditioner Cover # 290-3021
    The Adco RV Air Conditioner Cover # 290-3021 is 34" long x 29-1/2" wide x 14-3/4" tall. The other options that we currently offer wouldn't be large enough so I recommend reaching out to Adco to get a custom-fit cover made for your air conditioner.

  • Can Adco Air Conditioner Cover be Used When Driving?
    The Adco Air Conditioner Cover # 290-3021 should only be used when you are not moving, so just for when you are parked. The cover, which fits Duo Therm 13.5 - 15 Btu, Briskair 13.5 - 15 Btu, Duo Therm 57915, Advent 135, and Advent 150 air conditioners is designed to protect your AC from dirt and the like from getting into your RV but wasn't designed to withstand the consistent wind forces it would encounter when travelling.

  • Cover for Air Conditioner on 2019 Starcraft Launch
    The 2018/2019 Starcraft Launch uses a few different air conditioner brands across the different models. Our air conditioner covers are brand and model specific so you will need to identify what is on your trailer to find the correct cover. For example, the # 290-3021 fits Dometic Duo Therm model 57915, Dometic Brisk Air II model 59516, Advent ACM 135, and ACM 150 AC units.
