High velocity system for older home

My house was built in the mid 1800s and has no conventional ductwork installed. For quite a few years, this presented a problem. The living space was freezing cold all winter and ungodly hot all summer. We tried to get by with electric baseboard heaters, window air conditioners and box fans, but they proved ineffective. Living in the northeastern part of the country, our weather is especially severe. When the temperature drops down to negative twenty degrees, a portable heater can’t keep up. If the temperature climbs into the high eighties with excessive humidity, window air conditioners aren’t enough. Plus, these units were an eyesore and rather expensive to operate. I wanted a more streamlined, whole-house system. A couple of years ago, I learned about high velocity heating and cooling systems. This type of system is designed to retrofit into older homes without causing damage to walls or ceilings. It doesn’t require any major teardown or remodeling. The beauty of a high velocity system is the narrow diameter ductwork. The ducts are only two inches across and are flexible enough to snake through existing walls. They accommodate studs, plumbing pipes and electrical outlets and connect to very small vents that can be installed almost anywhere. A high velocity system works by way of a process called aspiration. It pumps conditioned air into the rooms at a high rate of speed, creating a gentle suction. The old and new air mix rapidly to raise or lower temperature quickly. Because the system doesn’t need to run all that long and the smaller ducts minimize energy waste, a high velocity option is quite cost-effective. I’m just happy to have a centralized thermostat and a comfortable home.
