Your cart is empty.Independent lab testing confirmed that Advent consistently averages 10% greater cooling capacity than the current 15K ratings when tested to the Air-Conditioning and Refrigeration Institute (ARI) standards. Users will gain more BTU output per unit with the 15K averaging 16.5K BTU resulting in the ability to cool a larger area in a shorter amount of time. The Advent 13 500 BTU roof-top high-efficiency air conditioner was designed specifically for the rigors of the RV lifestyle. Backed up with a No-Hassle 2-year Warranty the system is easy to install and operate fitting into a standard 14 1/4" x 14 1/4" vent opening for easy replacement of your existing unit. Premium features include additional evaporator cooling fins offering higher cooling efficiencies; An extremely rigid frame consisting of a composite of foam and metal parts allowing for quieter operation; Premium extra-thick water seal gasket keeping moisture from leaking into the RV; Removable and washable filters that keep the interior clean and free of debris; Motor overload protection for longer life; Non-ozone depleting environmentally-friendly refrigerant. Ducted or non-ducted ceiling packages and Heating Element options are available. With purchase of separate adapter kit the Advent can replace select Coleman and Carrier roof top units. Roof unit dimensions are 35.1" L x 29.9" W x 13.2" H.

I replaced the OEM with the same style Dometic AC... BUT this unit blows that one out of the water, it's quieter, colder and easy/simple to install. i ordered a 2nd one to install. Very Very impressed with this AC!

We were worried buying this brand, it is new to us, but customer service was great making sure we knew exactly what we were buying. The packaging was not great tho, it got bashed on the truck I guess, the vent side was crunched. There was no protective cardboard or paper , nothing on the top either which I thought was shocking bc it could have easily been cracked. We replaced our 34 yo Coleman on our 5th wheel and the weight difference was amazing due to hopefully a more efficient unit. The fan wouldn't come on at first so it had to be gone through to see if it had a problem more than us but the second try it ran good. We also bought the inside piece from the same brand, fit good, works good, we are happy with our purchase and can recommend it to others looking to upgrade. Ours is cool only, not heat. We also are replacing the wall thermostat with the 120v newer model for RVs. We did buy the extra warranty protection bc while these are great for the price but they are still pricey. Easy install and a bit quieter of course than the old one. It was a good buy for us.

I replaced one Dometic and one carrier unit with two Advent 15K RV roof air conditioners. They are attached to a ducted system in my 37 foot RV and they work great. The three speed fans provide very good cooling on high and pretty quiet on low speed. I am very satisfied with them and they have a full two year factory warranty. I replaced the ceiling control panel also and they came with new thermostats. They were very easy to install once I got the old ones off the roof and the new ones up there.

Replaced a damaged front a/c unit in my fifth wheel. It works well, and I would have given in 5 stars if there was even a little bit of installation guidance. Luckily it worked out ok, but it did take a couple of days to get it working because of the lack of info.

This unit is quieter than the Dometic it replaced, and bolted up with the existing inner unit. I was a little taken back when the unit arrived with no instructions, but, it seemed simple enough. Good news, the hardest part of the install was lifting the new unit onto the RV. (I leaned the longest ladder I had against the RV and pushed it up myself all in all pretty easy) Quick tip, make sure the mounting bolts don't rub on anything, that is what caused the old unit to fail after only 18 months.

Works great, but it is a little too loud. It cools good, so I can put up with the noise. It does have a lot of condensation that drips out of the ceiling assembly
