It runs on standard 115 volt power, works ducted or non-ducted, and drops into a standard 14.25 inch roof vent opening. Just remember the ceiling assembly and thermostat are ordered separately.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman RVP Mach-C 18 is a high-output rooftop air conditioner built for RVers who want to actually beat the heat, not just take the edge off it. At 18,000 BTU, this is one of the bigger units in the rooftop class, and that extra capacity is what you want when you're parked in full sun in July or running a longer coach where a smaller 13,500 BTU unit just can't keep up.\u003c\/p\u003e\n\u003cp\u003eIt runs on standard 115 volt AC power, so it works off shore power at the campground or off your onboard generator. The white low-profile housing measures 32.5 inches long by 25.1 inches wide and stands 12.6 inches tall on the roof, and the whole unit weighs 68 pounds. That footprint drops right into the standard 14.25 inch by 14.25 inch roof vent opening that most RVs already have, so on a lot of coaches this is a straight swap for an older or dead unit without cutting new holes.\u003c\/p\u003e\n\u003cp\u003eHere's the one thing to get straight before you order. This is the rooftop unit only. The ceiling assembly and the thermostat are separate parts, and you'll need both to finish the install. The ceiling assembly is the interior piece that handles air distribution and holds the return-air filter, and the thermostat is what tells the unit when to cycle. We call that out up front because it's the most common reason an install stalls. Order all three pieces together and you won't be sitting there with a compressor on the roof and no way to turn it on.\u003c\/p\u003e\n\u003cp\u003eThe Mach-C 18 is set up for ducted or non-ducted operation, which is a bigger deal than it sounds. On a non-ducted install, the air comes straight down through the ceiling assembly into one open living space. That's simple and it moves a lot of air fast, which is great for a single-room trailer or a smaller coach. On a ducted install, the cold air feeds into your RV's existing overhead duct runs and gets pushed to registers throughout the rig. If you've got a longer motorhome or a bunkhouse floorplan where you need cooling in the back bedroom too, ducted is the way to go. Same unit either way. You just choose the configuration that matches your coach when you set up the ceiling assembly.\u003c\/p\u003e\n\u003cp\u003eInstallation is a real job but it's within reach for a handy owner. The unit sets over the 14.25 inch opening on a gasket, and the ceiling assembly clamps up from inside to sandwich the roof between them. Two things matter a lot here. Get the gasket compression even so you don't get leaks, and don't overtighten and crush the foam. We tell people to snug the mounting bolts down in a cross pattern and check that the gasket is squishing evenly all the way around. Take your time on the seal and you won't be chasing a roof leak next spring.\u003c\/p\u003e\n\u003cp\u003eOne more practical note on power. An 18,000 BTU compressor pulls a healthy startup surge when it kicks on. If you're running off a smaller generator or you're sharing a 30 amp pedestal with a bunch of other loads, that inrush can be enough to trip a breaker or make the lights dip. It'll still run fine on a properly sized 115 volt circuit, but if you're near the edge of your power budget, a soft-start module is a worthwhile add. It smooths out that initial draw so the unit comes on gently.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Owners of mid-size to large RVs, fifth wheels, and travel trailers who want serious cooling capacity and don't mind that it's a two-or-three-part order. It's white, so it blends in with the typical RV roof and ceiling. It's not a portable or window unit, and it's not a plug-and-play appliance. It's a proper rooftop system that becomes part of the rig. Get the ceiling assembly and thermostat on the same order, take your time on the seal, and the Mach-C 18 will keep the whole coach comfortable for years.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e18,000 BTU cooling capacity, enough to cool a mid-size to large RV or fifth wheel even in full summer sun\u003c\/li\u003e\n  \u003cli\u003e115 volt AC power, runs off standard campground shore power or an onboard generator\u003c\/li\u003e\n  \u003cli\u003eDucted or non-ducted operation, feed one open living space or push air through the rig's overhead duct runs\u003c\/li\u003e\n  \u003cli\u003eFits the standard 14.25 inch by 14.25 inch roof vent opening, a direct-fit swap on most coaches\u003c\/li\u003e\n  \u003cli\u003eLow-profile white housing, 32.5 in L x 25.1 in W x 12.6 in H, blends into a typical RV roofline\u003c\/li\u003e\n  \u003cli\u003e68 pound unit sits over the opening on a gasket and clamps to the ceiling assembly from inside\u003c\/li\u003e\n  \u003cli\u003eRooftop compressor design keeps the hardware and most of the noise up top, out of your living space\u003c\/li\u003e\n  \u003cli\u003eWhite finish matches standard RV vents and interior ceiling assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized COLEMAN RVP reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes this air conditioner come with the ceiling assembly and thermostat?\u003c\/summary\u003e\n    \u003cp\u003eNo. The Mach-C 18 is the rooftop unit only.
