About This Product

No Ductwork? No Problem. Ramsond Ductless (Duct-Free) Mini Split Air Conditioning Systems can be installed in virtually any location. Ductless Mini Split Air Conditioners are also referred to as Zone Systems. They cool/heat the zone or areas in which they are installed. When the zone is in use, the mini split system can be turned on. When the zone is not in use, you can simply turn it off. This zone capability allows for substantial energy savings. Ramsond Heat Pump systems not only provide cooling during the hot summer months, but also provide efficient heating for the winter. They are far more efficient and substantially more economical compared to conventional central air conditioning systems. Ductless Mini Split systems are comprised of two main components: 1) The outdoor unit (Condensing Unit), and 2) The indoor unit (Evaporator Unit). The installation is simple. The indoor unit hangs on a metal bracket (supplied) that attaches to the interior wall, much like a picture frame. A 3 in. hole is then drilled through the wall. The Line set and communication wires are passed through this hole and connect the indoor and outdoor unit together. The Main power is supplied to the outdoor unit. The indoor unit draws its power from the outdoor unit. The system is operated by a wireless remote control (supplied). Simply set the remote control to the desired temperature and the system maintains the desired temperature.

    Q:I'm thinking about converting a cargo trailer into a camper and using this unit. I don't want it on the tongue. I was thinking about installing the condenser on the interior. I'd build a cabinet closed and insulated from the inside of the trailer and put a large vent on the intake side, a partition over the unit, and on the back side have a roof vent similar to evap refrig vents. I'd have to run a drain line so that it pokes out the exterior. This way the condenser would be inside the shell but with exterior ventilation. These are far more efficient and quiet than RV roof AC units. However, I'd like room on the front of the trailer for a pair of propane tanks. Does this sound feasible or with large vent will there still not be enough ventilation?

        We have been using the mini split all year in an 320 sq.ft. upstairs room, and are extremely satisfied. We were able to close all the a/c vents from the home unit, and the room has never been colder. Unit is super quiet, which was a "must" on our list. I did the install myself, which was very easy, and hired an electrician to do the hard wiring to the breaker panel. I have already recommended to several friends that came by the house to check it out.

        great unit for the cost. easy to install and works great. I installed this 12,000 BTU unit on the wall aside of a window unit installed through the wall. It works so much better then the 12,000 BTU window unit did , even when the window unit was new. this unit moves the air through the room so much the the other unit did, more control options then the window unit. And so much quieter then the window units. I will be buying more of these units to replace all my window units in the company. Well worth the cost

        Great Performance; Ultra Quiet; Very Efficient
        I got one of these to heat and cool a covered patio to home office conversion. I am amazed at how whisper quiet this unit is. When I turn it on "turbo" I can still barely hear it. On normal modes, you just cannot hear it. This actually includes the outside unit too. I see the fan running and I know everything is working, but you cannot hear it unless you get up close and personal. This unit obviously handles my 240 sq ft (12x20) office with ease. I would definitely buy again.

          Waited two weeks for delivery. However upon installation, noticed missing a drain hose. Called home depot and was advised for another two to three weeks to deliver the missing drain hose.
