High Velocity Heating on Long Island, NY

If your home has limited space for a duct system but is in need of better heating, then you may want to think about high velocity heating from T.F. O’Brien. A high velocity system uses an air handler indoors, as well as outdoor equipment, a line set of pipes that connect the indoor and outdoor units, and small diameter ductwork, which transfers the heated air throughout your home.

If you have an older, multi-story home where larger ductwork is space prohibitive, high velocity heating may be right for you.
