This installation is a master bedroom with a large closet and bathroom. The bedroom and closet have at least one wall that is an exterior wall. One 12,000 BTU Mini-Split unit was installed in the bedroom above a window such that the heated/cooled air flows toward the closet. Since the bathroom is an interior room, it does not need much heating/cooling to stay comfortable. The owner turns on the Mini-Split a few minutes before going to bed and the room is comfortable all night.

This one is a three room configuration: a kitchen and family room separated by a breakfast bar, and an office that had a five foot entryway. The family room has one exterior wall with three large windows and a short exterior wall with a glass door. The kitchen has two exterior walls and two large windows. Both of these rooms have ten-foot ceilings. The office is an interior room. NRG SVRS installed one 18,000 BTU Mini-Split unit to condition the air primarily in the kitchen and family room. A double French door was installed in the office door opening to isolate it from the family room, but it can be opened to condition the office.

This is another bedroom installation of a large bedroom on the sunny side of the house.  The Mini-Split unit is situated so that air flows across an exterior door and toward the bathroom.

This was a more complex installation. The living room is linked through a small hallway and entry area with an external door to a dining area. The homeowner originally wanted to heat/cool just the living room, isolating it from the entry area with a French door. We suggested adding one more door to close off a back hallway/staircase. This allows the Mini-Split to condition the living room (with the French door closed) or the entire living/dining room area with the French door open and the hallway door closed.

In this installation, the kitchen was already conditioned, but it was made more energy-efficient by the simple addition of a door between the kitchen and an unheated hallway. The bi-fold door was an ideal solution because the space on either side of the doorway was restricted enough so that a standard passage door would not fit.

This office area wis built over a concrete slab with three exterior walls. One interior wall is brick. So, there are plenty of opportunities to soak up the heat from the interior air in the winter. Two 12,000 BTU Mini-Split units were installed on opposite corners of the room for maximum heating/cooling, and a bi-fold door isolated the office from a break room.

This office was fitted with a Mini-Split and doors during construction. The salient feature is the wide eight-foot opening between the offices. A bi-fold door was used to isolate the lesser-used office from the main room. The 24,000 BTU Mini-Split was adequate to heat/cool both spaces.

This large bedroom had two exterior walls - one has lots of glass - with cathedral ceilings. It also has a large bathroom to heat. We installed a bi-fold door to isolate the bathroom from the bedroom, and installed a 12,000 BTU Mini-Split over the windows. One of the photos below shows the dressing of the pipes that run between the interior and exterior units of the Mini-Split.

This one is a very large open-plan space on two levels with a cathedral ceiling. There are three exterior walls, with one of them facing south. The Living Room was used less than the Dining Room, which was itself less used than the Kitchen. So, the 24,000 BTU Mini-Split was positioned to blow air preferentially toward the Kitchen, though circulation is such that all rooms are conditioned nearly uniformly. The two photos depict both the interior and exterior units of the Mini-Split.
