Do you have a single line of ducts running down the middle of your RV?

Single Line Center Ducts

Finally there is a solution! The new SCLD A/C Connect by KoolRV connects your AC to your ducts, creating a dramatically improved cooling efficiency. Our test model for this system was a 2019 Fleetwood Flair 30P. We conducted a 20 minute cooling test before and after installation. Without our system the RV cooled just 3 degrees in 20 minutes. With our system the RV cooled 14 degrees in 20 minutes, an improvement of 467%!!!

This system is currently designed for the Coleman Mach 1, 3, 10, 15 and Q. If you have a different make or model AC please email with your AC information. We develop our products based on customer demand. If you ask for it, we’ll build it!


Did you know that your RV air conditioner isn’t directly connected to your ventilation system? The A/C Connect system for Coleman Mach Series air conditioners is designed to directly connect the cold air from your air conditioner to your RV ventilation ducts. The result is a dramatically cooler RV on those hot summer days! Stay comfortable, save energy (and money) and be the envy of everyone in your campground!

Our systems are made of two main components, the AC adapter and the vent adapter. The AC adapter is precision built for each of the major AC manufacturer’s models. Our vent adapters are a fairly standard 7 inch wide by 1.5 inch tall size. What if your RV has a non standard size vent opening? Easy! Click here for instructions on how to adapt our system quickly and easily to your rig. 


#1 - If your Coleman Mach AC resembles either of the ACs in our pictures, you are on the right page!

#2 - If you have a single line of vents running down the center of your rig please check your duct openings to make sure they are on the front and back of your plenum NOT on the sides. This model is ONLY for ducts with front and back vent locations. Please click on our “Store” menu above to select our other systems if your ducts are on the left and right sides.

#3 - Our vent adapters are made for the “standard” RV duct setup of 1.5” high by 7” wide. Some manufacturers have vents substantially taller, wider, narrower, shorter (you get the picture). If this is you, click here for instructions on how to adapt our system to your RV.

#4 - To maximize your benefit you will want one AC Connect for each AC in your rig. It is not required, but recommended.  

Our patent pending design is compatible with both standard and shallow plenums.

If you are unsure of your Coleman Mach model you can also measure the cold air exhaust opening in the bottom of your air conditioner. (Reference our picture of the bottom of your A/C) If the opening is 5 1/2 inches wide by 4 3/4 inches across your Coleman Mach A/C is compatible!
