The indoor unit is installed on the interior of an exterior facing wall. The installation is extremely simple. The indoor unit is equipped with a mounting bracket (included). This mounting bracket is secured to the wall. A three inch hole is then drilled through wall and the connecting pipes and sires are passed through this hole. The indoor unit is then connected.The indoor unit then simply hangs on the bracket much like hanging a picture frame. The outdoor unit is typically placed on a flat surface outside. The indoor and the outdoor units are connected by a set of wires for power and communication. The indoor unit draws its power from the outdoor unit. You will need to supply the power to the outdoor unit. You will need a 20 Amp breaker. Once the indoor and outdoor units are connected, then the connecting pipes (Line Set) are attached. pre-flanged and pre-flared. The final step is to open the valves on the outdoor unit opened to release the refrigerant into the line sets.

Ductless mini split air-conditioners are relatively new to North America. However, they are the most commonly used system of air conditioning throughout the rest of the world. Ductless systems are also referred to as 'zone systems.' Understandably, ductless split air conditioning systems are becoming more popular in homes and offices, even when they are equipped with advanced central air conditioning system. By providing zone cooling, Amvent ductless split system air conditioners save energy, since only the rooms that are occupied and used need to be cooled. Simply stated, they cool the 'zone' or the area in which they are installed. They require no expensive ductwork installation. This is the reason that they are far more efficient than conventional air conditioners. You can turn on the system when you want to use the area/zone and when not in use, the system can be simply turned off, saving electricity and money. Operating costs are much lower than those of central systems that cool every room, whether or not the room is in use. So, with a ductless system you can control the temperature of a zone where it is located. Therefore, you have the benefit of cooling only the room that you want, while leaving the central AC system off.

Ductless mini split system air conditioners combine the zoning flexibility of a conventional room unit (a single air-conditioner installed through a wall or a window frame) with the whole-house cooling potential of central systems. Like central systems, they have two main components: a compressor/condenser (outdoor unit), as well as an air handling unit (indoor unit/evaporator), which contains an evaporator and a fan.
