Ductless mini-split or duct-free HVAC units can be a useful alternative to cool and heat homes and businesses. Through a variety of sizes, and capabilities of controlling the air temperature in individual zones or rooms in the building, they offer both economic and environmental advantages.
HVAC companies are installing them in multi-family housing, renovations of older single-family homes, as well as businesses' server rooms, waiting rooms and office spaces. They also have a money and energy savings advantage, when some areas of an office space are used infrequently or not at all (such as a build-out waiting for occupancy), by only cooling the space that is occupied.
Duct-free systems, as the name implies, have no duct work and consist of an outdoor condenser and an indoor air-handling unit. These are linked together with tubing that houses the power cable, refrigerant, and a drain for condensation. In many ways, they operate in a manner quite similar to a standard air conditioning system.
Air conditioning technicians have noted that the main advantages of duct-free systems are ease of installation, cost savings, energy savings, and flexibility in locating the system for cosmetic concerns and sound control, as wel l as logistical applications.
The benefits are often overlooked by customers, but we like to point out that duct-free systems can be installed in places where conventional ducted systems simply can't go. Options for interior design include ceiling and wall mounted units, drop ceiling applications and even a picture gallery unit that allows the owner to customize the look of the space. Floor-standing models are also available. Most indoor units have profiles of about eight to eleven inches deep, and have a range of aesthetically-refined designs suitable for any home or office. All models offer a remote control to easily make adjustments to the system's air flow pattern or temperature, and on and off when it's positioned high on a wall or suspended from a ceiling.
Duct-free systems can also help to keep your home safer because there is only a small hole for the tubing to pass through the wall. Window-mounted and through-the-wall room air-conditioners, unfortunately, can provide an easy entrance for intruders.
The savings can be significant in terms of installation and energy use.
For many of our customers, the unique advantages of this type of system are important. Our installers are highly trained, they attend hands-on training, as well as up-to-date online training and testing. I would caution against using a company whose technicians are not proficient in this type of installation, as each unit must be correctly sized and placed. An error here could result in wasted energy, improper temperature or humidity control, and greater long-term operational expenses.
We encourage home and business owners replacing existing systems, building new or remodeling to consider duct-free systems.

More than three decades ago, Mitsubishi Electric launched its North American HVAC division bringing ductless systems to the U.S. Within seven years, it had begun its campaign to enlist quality dealers and by 2009, it introduced its Star Lineup , many are EnergyStar rated and qualify for federal tax credits. Just two years later, its split-ductless systems won the Top 10 Product Award from BuildingGreen. For decades now, Mitsubishi Electric US, Inc.
Cooling & Heating Division's advanced climate control systems have provided personalized comfort while conserving energy and promoting environmental sustainability. Mitsubishi Electric is proud to be the third largest manufacturer of cooling and heating systems in the world. But its goal is to be first globally in providing "comfort without compromise."
