As the owner of an older home that lacks conventional ductwork, I’ve spent years struggling with temperature control.
I live in an area where the winters are brutally cold and summers are excessively hot and humid.
It’s impossible to maintain a comfortable living space with space heaters and window air conditioners. However, I was unwilling to gut the residence down to the bare studs in order to install ductwork. A few years ago, I discovered high-velocity temperature control. High-velocity systems utilize mini ducts that are just two inches in diameter. The ducts are skinny and flexible enough to fit in between studs in a wall, between ceiling rafters and accommodate plumbing pipes and electrical outlets. The supply and return vents are also much smaller. They are round, unobtrusive and allow freedom of location. The installation is non-invasive and less expensive. There’s no need to tear down walls, rebuild or clean up a big mess. With a high velocity system, hot or cool air moves from a compressor or heat pump into an air handler that sends the conditioned air through the ducts and vents at a very high rate of speed. Because of this, the air circulates and mixes quickly. The system achieves desired room temperature with shorter running times. It provides excellent climate control and uses less energy to operate. Plus, the mini ducts are insulated to prevent energy losses. Although high velocity systems don’t allow for zoning, I’m just delighted to have centralized temperature control. The system easily handles severe local weather, doesn’t detract from aesthetics and has allowed me to get rid of my assorted collection of heaters and portable air conditioners.
