Energy efficiency & comfort control
Ductless mini split air conditioners and heat pumps have become one of the fastest growing segments in the HVAC industry in the US. Already the dominant system throughout the world, ductless split manufacturers like Mitsubishi, Gree, Fujitsu, Panasonic, and LG are bringing more and more ductless models to the US market.
Our single-room ductless splits comprises an outdoor condenser, which cycles and cools the refrigerant, and a single indoor air handler. A line set kit connects the two pieces - ours includes the liquid line, the suction line, and the electrical line.
The refrigerant flows from the condenser to the indoor air handler through the line sets. We prefer the JMF brand, as they include the electrical line already in the kit. These line sets are semi-flexible and made from copper. When the refrigerant reaches the indoor air handler, that unit uses it to cool the air and push the cold air into the room.
In the winter, this process is reversed with a heat pump, and the system cycles the air in the opposite direction to provide energy efficient warm air.

Advantages of Ductless Mini Splits
Overwhelmingly, the main reason to consider a ductless split is the energy efficiency and savings you'll see from your energy company. The average central air system has a 13-14 SEER (seasonal energy efficiency rating). We have ductless systems with SEER up to 30.5, and technology just keeps getting better.
So what does that mean to you and your energy bill? It means with the most-efficient systems, your *annual* cooling cost could be under $100. No kidding!
For the average American who has an average cost per KwH and cools their home an average number of days per year, the annual cooling cost on the Gree Terra 9,000 BTU model is about $88. Of course exact costs vary by region, your local utility company's prices, and how cold you like your home...but this gives a rough idea of just how cheap it can be.
Did you know that up to 30% of energy is lost while the cooled/heated air passes through central AC ductwork? It's even worse if that ductwork runs through an attic or something similar. Ductless systems don't have this loss - making them incredibly efficient!
It's also a lot easier to install a mini split than it is to install ducted systems. Only about a 3" hole is needed through the wall to run the line set from the condenser to the indoor unit. The indoor air handler itself just mounts onto a bracket that's attached to the wall.
Interior Design Options
While the most-common ductless air handler is the wall-mounted type, there are actually a variety of form factors to choose from. Some consumers prefer to not have anything on their walls, so they choose either a ceiling suspended, or even ceiling recessed model.
Unlike bulky window air conditioners, you can actually hide your AC unit if you'd like with a ductless system. To browse each type of design style, select below:

Installation – How It Works
It's important to note that a licensed professional should always do installation of these systems. We advise this not only for your safety, but also because the manufacturer's warranty becomes void if not installed by a licensed contractor.
With that said, many consumers are curious about how installations are performed. Installing a ductless split is much easier than doing a central air system, but it's still a more challenging project than just setting up a window unit!
