Buying an older home that is full of historic detailing but lacks conventional ductwork made heating and cooling extremely difficult.
We were unwilling to tear down the existing walls and ceilings and destroy the architectural integrity of the home.
However, trying to manage comfort with window air conditioners and portable electric heaters was problematic. These units were ineffective, unattractive and cost quite a bit to operate. I started to research other options, looking for something more energy-efficient and less obtrusive that would provide centralized temperature control. I came across high velocity HVAC that utilizes mini ducts that are flexible enough to snake through existing walls and ceilings without causing damage. This type of system is one of the easiest and least disruptive to install. It requires only small holes to be drilled into the walls to accommodate pipes that are only a couple of inches in diameter. The vents are very small and available in all sorts of styles and colors. While the upfront investment into a high velocity unit is quite a bit more extension than a conventional system, running costs are far lower. We avoid the up to 20% energy losses that are typical with traditional ducts and benefit from around a 25% savings on our utility bills. The high velocity system moves air very quickly, creating a process of aspiration and cooling off or heating up even large rooms rapidly. This not only achieves ideal comfort without delay but minimizes operation. Shorter run times means less energy consumed, making the system wonderfully energy efficient. Because the mini ducts are individually insulated, they are also quiet. Another advantage of such a high powered system is better air quality. Because the air provides more velocity when moving through the narrow ducts, it carries away dust and debris and avoids build up. There’s less chance of contaminants getting introduced into the breathing air.
