When my husband and I bought an older home, we had some issues with temperature control. The former owners were getting by with space heaters and portable cooling units. These units were ugly, inefficient and not totally effective during severe weather. My husband and I wanted to retrofit a whole home HVAC system. Unfortunately, dealing with an older home, we had some challenges to overcome. The walls are constructed of plaster and lathe which would be a huge mess and expense to tear down for the sake of installing ductwork. Plus, the walls were built with the studs turned sideways to gain more living space. The narrow walls won’t accommodate conventional sized ductwork. My husband and I worried that we would be unable to install a whole-home forced air heating and cooling system. We consulted with a local HVAC contractor, who told us about high-velocity systems, which are ideal for retrofitting into existing homes. This innovative technology draws hot or cold air from either a heat pump or compressor outside the home and sends it into a high-velocity air handler. Rather than large dructs, the system features two-inch, flexible tubing. The handler pushes the heated or cooled air through the tubing with a tremendous amount of pressure. The vents that supply the conditioned air to the various room are round, only five inches in diameter and unobtrusive. Because the air circulates very rapidly through the living space, the room temperature raises or lowers very quickly. The system doesn’t need to run for long periods, uses very little energy and doesn’t cost much to operate. Low monthly costs and exceptionally efficiency made a high-velocity system sound like the perfect solution for our requirements.
