Product Overview

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.

What is the steer for this product

Asked by: Jon
Just so other patrons who may look at this site information,the question was asked,what is the Seer, which stands for "Seasonal Energy Efficiency Rating". The higher the rating,the more economically the unit will be to operate.

Could u put compressor in garage? Would there be enough airflow? Would it be a fire hazard

Asked by: ScottH
Yes, as long as the actual compressor unit is outside in the lines run into the Attic with the floor component and remote control are the only ones inside the Attic. I know this because we use them on specific designs in extreme heat make shift buildings in Afghanistan

12,000 BTU 1+ Ton Ductless Mini Split Air Conditioner and Heat Pump - 110V/60Hz is rated 4.2 out of 5 by 45.
Rated 4 out of 5 by from Nice kit, works as advertised, only reason for giving 4... Nice kit, works as advertised, only reason for giving 4 stars is the installation manual is not as user friendly as it could be and it leaves some critical details out, like where electrical connectors are within the unit and more thorough vacuum and servicing instructions.

Rated 5 out of 5 by from great unit for the cost. easy to install and works great. I installed this 12,000 BTU unit on the... 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

Rated 4 out of 5 by from Excellent product and easy to install This freezes me out of my home. It's pretty quiet, on the low fan setting you can barely hear it. 2 problems that make it only 4 stars. 1. The instructions are terrible. I seems they were written for an older model. This model is easy to set up, but the instructions make it seem a lot harder. Also, the purging instructions are on the website, not the manual. (Make sure you open the valves ALL the way open.) 2. The unit came with a lot of extra piping but no tools or instructions on how to cut it down. Now I have 10 feet of extra pipe coiled up behind the compressor. But it works fine

Rated 4 out of 5 by from We are happy so far with this products performance The only problem with this product is the installation directions. The users manual is not model specific. It is a general split system manual for most models. Did not explain the Pre Charged feature that my model came with. It did not describe the wiring connections effectively. I am a professional contractor and I had to use every bit of my ingenuity to figure out how to install it. I am left with a low voltage wire with plug in connections that is not described in the directions. I have no idea what its for. But the system is working well in my 20'x 20' family room.

Rated 5 out of 5 by from Instructions STINK: But product works... Bought this for an outside office (Insulated Tuff Shed). I poured a slab waited a day and on Saturday at 10AM started the install. It was completely installed by 3PM and worked the first time I turned it on. The biggest issue was the instructions were not clear about opening the low/hi pressure ports to let the Freon flow. I read and viewed multiple sets of instructions for similar units and figured out what to do prior to turning it on. I also purchased a flare tool and cut the piping to length. The piping is the thinnest copper tubing I've ever worked with. Very quiet unit and it sure does keep the office cool. I hope the heat works as well. if I had to depend on Ramsond's manual it would not be working.
