I have a 4 Zone Mini Split System. It's 4 years old and works great. Each indoor unit is 9000 BTUs. The whole system is 36000 BTUs. It is a 3 Ton system, 24 SEER. I have the outdoor unit, 4 indoor units, 2 remotes, owner's manuals and the covers for the linesets outside. I do not have any linesets or drain hose. I purchased this system from Alpine Heating and Cooling. You can get any parts you need from them or from anywhere you choose. I can only find 2 remotes at this time. I will look for the other 2. Any remote will work any and all of the indoor units. The outdoor unit is Blueridge BM36M23C and the indoor units are Blueridge BM09M22WM. We used this system for 2 years until we were done remodeling. Then we ripped out the old furnace and got an air handler for inside. $700 or best offer.

The first link shows the indoor units. The second link is the spec sheet for the outdoor unit. And the third link shows what the system looks like. Alpine has changed the model number, but it is the same system. If you have any questions, please ask.
