Keep your rooftop AC unit clean, dry, and protected all off-season long. The ADCO 3003 cover is purpose-built for Briskair and Duo-Therm units, blocking UV rays, wind-driven debris, leaves, and drafts before they can degrade your shroud or clog your coils.
ADCO has been manufacturing protective RV covers for decades, and their AC cover lineup is engineered to the exact footprints of the most common rooftop units on the market. The 3003 is sized specifically for Briskair and Duo-Therm shroud profiles at 35 inches long by 27 inches wide by 13 inches deep -- no guessing, no trimming, no ill-fitting generic cover sliding around on your roof.
At just 1.5 lbs., this cover goes on and comes off without a production. The parachute-style drawcord cinches underneath the AC shroud lip for a secure, rattle-free fit even in highway driving conditions or high-wind campsites.
The outer shell is tough vinyl bonded to a jersey backing -- resists tearing and abrasion while the backing prevents moisture from wicking through to the shroud surface.
Prolonged sun exposure cracks and yellows AC shrouds. The polar white vinyl reflects solar heat and shields the plastic from UV degradation during storage and transit.
Seams are reinforced and non-tearable, keeping the cover intact through seasons of installation and removal without splitting at stress points.
The drawcord runs the full perimeter of the lower edge and locks with a barrel-style toggle, keeping the cover snug without bunching or requiring tools.
Leaving a rooftop AC unit uncovered during storage invites a surprising list of problems: wind-driven leaves and debris pack into the coil fins and restrict airflow; UV rays chalk and crack the plastic shroud; birds and insects nest in the interior cavity; and cold drafts pass through the unit into the coach, raising interior humidity and heating costs.
Installation takes under two minutes on most rigs. With the AC unit off and cool, center the cover over the shroud, work the drawcord evenly around the perimeter, and cinch the toggle. Remove the cover before operating the AC -- running the unit with the cover in place will restrict airflow and can overheat the compressor.
This cover is backed by ADCO's limited 3-year manufacturer warranty against defects in materials and workmanship. ADCO is a well-established name in the RV cover category with broad dealer and replacement-part support.
