Whether you are installing a new HVAC system your workshop, office space or in an old historic home or you just need to heat and cool a small space that is not used very often, you can turn to De Hart Plumbing, Heating and Cooling to help. We offer a full line of high-efficiency duct-free HVAC solutions that can fit your needs without compromising the integrity of your space or comfort.

A duct-free HVAC or heat pump typically consists of a wall-mounted indoor unit combined with an outside compressor. These systems are most often used in a situation where a traditional window AC unit or baseboard heating system would be considered in areas of an older home or a new addition to a home. However, unlike traditional window units, duct-free units require only a very small hole to be drilled through the wall, making these systems less vulnerable to air leakage and security problems.

Duct-Free HVAC Split systems are comprised of two major components—indoor units and outdoor units—that are connected through refrigerant piping and power wiring/communications cable. These Inverter heat pump systems provide a smart alternative to both central HVAC and window-mounted air conditioners and are available in a variety of configurations to suit different cooling and heating situations. Installation by a qualified HVAC contractor is safe and easy—little to no duct work or sheet metal is required.

Art Cool™ Mirror Duct-Free HVAC systems feature sleek, mirror-finished indoor units, and outdoor units with energy-efficient Inverter technology.

Single zone systems that feature an innovative design and high-efficiency levels. The mirrored wall-mounted indoor units allow for easy installation, while the majority of systems in this line achieve Energy Star and tax credit qualifications.
