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 AC solutions that can fit your needs without compromising the integrity of your space or comfort.

A duct-free AC 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.

The slim, contemporary styling of the Art Cool™ Gallery Duct-Free AC inverter models will appeal to today’s discerning customer.  Available in 9,000 and 12,000 BTU/h, models come with a frame that allows the customer to modify and personalize the unit with their own artwork or photography – the ultimate in custom design plus with energy-efficient Inverter technology.

These indoor units, combined with small footprint outdoor units, provide both physical comfort and a stylish aesthetic.
