Coleman-Mach 08-0080 Mach 15 48204 Series Air Conditioner Upper Unit 48204C966-15,000, Arctic White

This is a nice unit. I read hundreds of reviews before making my choice to replace a Mach 3 13.5K- BTU unit on my camper, comparing technical specs and even performed servicing the Mach 3 before I decided to make the swap. I got to look under the cover for both and compare components. The inside components between the two units have nearly the exact same design layout, components, blower/fan, etc. but the Mach 15 is a little bit smaller package and a 2 piece shroud. I had trouble sliding the old Mach 13 shroud off for troubleshooting without dragging cover across evaporator fins but Mach 15 2 pc shroud is much easier. But it will flex a little so don't lift unit with it. The unit is easy to unload and lift to the roof, but the two piece shroud is not for lifting and sill crack if not careful. This went on a pop up camper, but If I had to hoist to a higher roof installation I would consider leave it in the box/pallet and unpackage it then. The pallet this unit cam on was only 15 lb wood and wrapped in cardboard but truck carrier delivered in perfect shape. It comes with the gasket installed and crush indicators so you cant screw it up. Follow the installation instructions in the book and save yourself hundreds from a dealer install. If you have the skills to assemble a grill you can swap units out. Follow the book. The inside unit is a perfect match for the 14x14 opening and easy to complete installation, I completed the job in under 2 hours. The duct installation trimming and taping took the longest just to make sure it was tight so no air leaks from unit. Remember the air comes straight down into the roof unit and makes a 90 degree turn to vents, so this vinyl duct will puff up like a balloon and any leaks will recirculate back into the inlet side. I'm not sure this unit is that much quieter than a Mach 13,5 BTU because its probably using the same blower with a more efficient compressor and evaporator but it does run smooth with no rattles and provide plenty of cold air. Is it worth the price difference of $100 for an upgrade? yes probably for us and should never need to worry about keeping cool even in middle of hot summer camping in Florida. If we get 6 years out of it, for $100/year its a reasonable tradeoff. Good luck with your choice. installation is easy. Nice unit.

Product was purchased for a NEW install in my old camper. Seller contacted to verify that "this is the upper unit only," and asked "do you need to purchase the lower control panel also?" I was aware that they were sold separately and had purchase both parts (but ended up from different vendors on Amazon). NOTE: ALL HARDWARE IS ONLY INCLUDED WITH THE SEPARATELY PURCHASED LOWER CONTROL PANEL. That means all Coleman screws, mounting frame etc are not supplied with this Upper Unit. This air conditioner included the install manual and the foam seal (attached to the unit). You do not need to purchase the Amazon suggested "foam seal" as it is included. The instructions to install the Lower Control Panel are included in the install manual for the Upper Unit. There are no instructions included with the Lower Control Panel package. Instructions to install this unit are also available online at manufacturer's website. Unit arrived on a 24' semi trailer with Tommy lift but the driver and I lifted the palletted package off the truck easily. The packaging and the product arrived in good shape with no cracks or dents. Installation went as expected into a 14" x 14" roof vent that existed on my camper. Due to my camper being a 15 yr old Ultra Lite, and in marginal condition, I added a steel U support beam in front and behind the mounting position to add support. My camper was prewired for 20amp service for an AC unit so connecting the wiring was not difficult. The unit fired up as expected and cooled adequately. READ THE INSTRUCTIONS. Dont use my review as a guide for install, my camper is... special.

Purchased a used RV and found that the AC would only drop the input air temperature by 4-5 degrees. Watched many videos and read a lot on how to troubleshoot. The filter was clean, evaporator and condensor were clean, control module electrical functions were good, the compressor and fan were running but the evaporator was barely cool to the touch and it just wasn't cooling like it should. My conclusion was that either it had slowly leaked out refrigerant or the compressor is going out. Since you can't easily/affordably replace the compressor or charge the refrigerant I decided to order a new unit. It arrived quicker than expected via freight delivery and was securely fastened to a pallet. The unit works great after installation and cools the input air down 15-20 degrees. Surprised at how easy it was to replace: 1. Remove 4 mounting bolts from inside RV 2. Dismount control module in air intake 3. Remove freeze sensor from evaporator (white wires from control module to piece stuck in fins on air intake side) 4. Disconnect the one square electrical connector that is part of the new unit 5. Reverse to install The hardest part is getting the new unit on top of the RV and the old one off. My son and I were able to muscle it up on top but at least one more person would have really helped. Be careful when moving the units around on top and not drag them on the liner. Unfortunately I cut my liner and had to order repair tape to fix it. When moving use two people if possible to lift it instead of 'scooting' it around. Overall a good experience and would definitely purchase from this seller again!

Just installed it. Looks good. Fans work, but it doesn't cool at all.

My friend helped me install this as it weighs 80+ pounds (keep the unit in the shipping boxes to safely haul it to the top of your rig without damaging it--rig or AC); there are plenty of videos on You Tube demonstrating how to do this effortlessly and safely. Aside from that, this installation was ridiculously easy. We merely pulled the old unit straight up and discarded. The new unit fit the existing hole perfectly (the old unit was a Mach 3 15K). The hard foam(?) seal pre-installed around the portion of the unit that sits over the Ceiling Assembly, made a watertight seal without any tape, caulk, etc. The process of screwing the Ceiling Assembly (sold separately) and outside unit together creates the seal. We just came out of several weeks of nearly continuous, driving rain from tropical systems off the coast, and not a drop of moisture came into the RV through the AC unit. Although I do a great deal of wiring in my profession (not a licensed electrician), the wiring for this unit was very simple: hot to hot, neutral to neutral and ground to ground. All other electrical connections were plug and play. I also purchased the optional heater (I reviewed that as well); installation involved a single plug and a single screw--again, simple. This unit is CIA-spy-drone quiet compared to the Mach 3 13.5 K unit on the rear of my rig. In fact, I thought the compressor was not kicking in until a nearly frost-bitten hand placed in front of the blower motor proved otherwise. I test-ran the unit on high for the rest of the day (90+ temperatures on the pad). Later that afternoon, my wife and I decided to see how the AC was performing. She would not even enter the rig it was so cold! The only downside is that this unit is several inches higher than the old unit--a worthy tradeoff in my humble opinion.

This unit did NOT come with control box so I had to transfer the old control unit to the new a/c.

The air-conditioning unit works fantastically, much better than the old R22 unit I had. Installation was very easy, and the unit has been wonderful during several hot weather cycles. Delta-T is always over 20 degrees! So much for the praise.... I was disappointed with the shipping container. The unit was shipped by truck from Tennessee to California, but barely survived the trip. The AC unit was bolted to a flimsy pallet, and during transit the bolts pulled through the soft wood of the pallet. Over the unit, were two plastic straps holding on some cardboard that was placed around the unit and the pallet. During transit, the straps loosened, the cardboard was torn, and the pallet was broken. Somehow, the AC unit itself survived without a scratch, but the packaging looked like it had been through a war. I kept everything from my old AC unit(same manufacturer), and I was glad I did. What is not clear in any of the documentation I could find is that the new AC unit does not come with the controlling circuit board. I recovered the controller board from my old 13.5K BTU unit, installed it on the bolts near the evaporator coil of the new AC unit, and the old controller seems to work fine with this new 15K BTU unit. The new AC unit did come with the roof gasket installed, so that was terrific. I also had to use all the mounting brackets, bolts, plenum baffles, and screws from the old original AC unit.

This was a do it yourself project. I was more than a little bit apprehensive about the ease of installation of this Coleman Mach 15 roof mount A/C unit. My skill level at this was "0". I am new to the Rv world so my experience with these products was very limited. There were no on line articles clearly outlining the replacement procedure. Much to my delight, the removal of the old unit was easy. My original unit was a ducted one so I had to remove the small black plenum in order to gain access to the wiring board. Here is where I got nervous. There were several wires going to a metal box and one going inside of the cooling coils. I found that the pair going to the coil was the thermostat sensor and removal was easy as simply pulling on the wires since they had been inserted flush with the fins. Installation of the thermostat sensor was done by pushing the metal sensor into the new unit at about the same location as it had rested in the old unit. Next was a group of wires plugged into the metal box containing this collection of various colors and sizes of wires. The group terminated into a nine pin plug. All pins were not used however, and unplugging was easy. The metal box had several wires attached to the face of it and a piece of jacketed house wire entering the box. I did not have to remove any of the wires from that box except for the 9 pin plug. The box was secured with two screws. After removing the two nuts, the metal junction box was allowed to simply hang down supported by the wires. The old unit was now ready to be removed. Four very long screws now held the old A/c I place. These were removed and the unit was removed from the 14 inch square hole. The new unit already had a roof gasket affixed to the bottom. Once in place and centered over the existing hole through the roof, I found two screws protruding into the new ac housing. These screws and the nuts that were removed from the electrical box were reused to refasten the old junction box. I inserted the old thermostat sensor into the new coil fins. Replaced the duct then the four very long screws securing the unit in place. The entire job took about a hour from start to finish. Very straightforward removal and installation.
