Furrion Chill 14.5k BTU AC Installation - Replacing Old Coleman Mach 3
Furrion Chill Air Conditioner Installation Video
The other day I removed our 12-year-old OEM Coleman Mach 3 air conditioner and installed a new Furrion Chill 14.5K BTU unit from Lippert. The Furrion replacement model comes in black or white. 14.5K or 15.5K BTU and includes a conversion kit. The conversion kit contains metal spacers, bolts, and an electrical harness.
With the conversion kit, I can reuse my existing Coleman Mach 3 controller board, air box, OEM ceiling ducting, and thermostat. This makes the replacement process fast and super easy to do. I just needed to remove the old unit by taking out four screws and four long bolts and unplugging the control board box.
The hardest part of the job is getting the old AC down and the new AC onto the roof. They weigh in the neighborhood of 85 lbs, so helpers are strongly recommended.
After removal, I thoroughly cleaned the RV rubber roof under the old AC and resealed the output ducting with new metal duct tape. Then I positioned the new Furrion Chill AC over the existing roof hole.
I reattached the interior metal frame using the supplied conversion kit and tightened the bolts to clamp the AC down. Then I installed the controller box, plugged it in, and screwed the air box cover back on.
So far, the new Furrion AC is performing well. Improved cooling performance with noticeably quieter operation than the old Coleman. I'll use it for a few hot weeks in August, then come back with a full review video. Stay tuned.

Nice video! It will be good to see your review later to see if this will be a great replacement option for us down the road.
That is for detail photos up inside. When you resealed with aluminum tape did you need to use a cleaner to remove old tape/adhesive?
The old tape came off easily. I just wiped off any surface dirt and retaped.
Furrion Chill Air Conditioner Review
In this video, I return after nearly a month of real-world usage of the new Furrion Chill AC unit I installed last month. We had a decent stretch of hot weather in August with highs up around 85 - 90F. The AC was put through its paces, cooling our rig, and did a great job.
Overall I'm pleased with the operation and performance of the new Furrion AC. It was about 20% quieter than the old Coleman Mach, with improved cooling performance. The Furrion is easier to take apart for cleaning, maintenance, and any repairs that may be required.
The only negative I can see is how much plastic is in the design. Because of this, I have concerns about the long-term durability versus the old Coleman's mostly metal construction. Time will tell, I guess.
