A mini split ductless air conditioning unit provides a highly efficient, quiet, low-cost professional solution for your cooling and heating needs without requiring any ductwork.

This energy-efficient system is the ideal solution for open-room applications such as classrooms, sunrooms, open floor plan flexible-use spaces, man caves, home theaters, offices, studios, bedrooms, bonus rooms over the garage and even basements and garages where heating and cooling is desired.

Where there is an open interior space need for heating and cooling, Ductless heating and cooling units are the answer. This sleek-looking unit is mounted on the wall, working in concert with an exterior condenser requiring only a small hole to run the lines from the air handler to the condenser.

The fans deliver continuous airflow and circulation with year-round temperature comfort and are easily adjusted with a remote control that comes standard with each unit. Because the air handler is mounted above eye level, it is aesthetically attractive, blends well and does little to impede with furniture and decor placement. Mini Split units are an eco-conscious alternative to traditional HVAC systems

Ductless air conditioners are installed with an outside compressor and condenser unit that sucks in air, cools it, and channels it via an exterior conduit through the wall to an opposing interior unit attached to the wall of a room. A remote control allows air to be cooled to the needed temperature and either fanned throughout the room or directed to a specific zone. Ductless systems also have the ability to situate mini splits in remote corners of a building — for instance, in small doctor’s office suites or finished basements in homes — gives them added appeal.

Major mini split manufacturers include Mitsubishi Electric, Fujitsu, Daikin, Gree and LG, as well as the Carrier subsidiary of Farmington-based United Technologies.

Ductless systems have the ability to heat or cool specific rooms, lowering costs associated with whole house/office HVAC systems. Manufacturers have worked to lessen the obtrusiveness of their physical appearance, making them a great choice for homebuyers looking to maintain a stylish presence while installing a new heating and cooling system. There are versions that can be installed in drop-ceilings to stay out of sight as well. Unlike traditional air conditioners, mini splits do not occupy window space, allowing an increase in natural light and a decreased risk of security breach through the window unit.

Ductless units are more efficient than central air conditioning systems that can sometimes cost the average user 30 percent loss of energy efficiency.

Sales of ductless units are dominated by local heating, ventilation and air conditioning (HVAC) installers, and London based market research firm, Technavio, estimating that ductless split air conditioner sales are increasing at a rate of 6 percent annually.
