Handling temperature control in older home with high velocity system

My husband and I were delighted when we were able to afford a home in the historical district.

The house is around two hundred years old and features a lot of the original millwork, stained glass and hardwood floors.

It has high ceilings, a balcony across the second story and a widow’s walk. It’s absolutely beautiful but there are some drawbacks. Because it is on the historical register, we can’t make any renovations without getting approval first. The walls inside the home are the original plaster, especially narrow and not outfitted with modern ductwork. The former owners of the home were managing heating and cooling with electric baseboard heaters and portable air conditioners. Not only was this collection of heating and cooling equipment unattractive and cumbersome, it was ineffective and costly to operate. The house was freezing cold during the winter months and overheated and clammy during the summers. I did some research and came across high-velocity heating and cooling. This type of system is designed specifically to retrofit into older homes without compromising architectural integrity. Once I got approval to install the unit, I went ahead with the installation project. The high-velocity system uses very narrow, flexible mini-ducts that are snaked into existing walls and accommodate obstacles such as studs and plumbing pipes. These ducts connect with compact equipment that is located in our attic and vents that are only six inches in diameter. The high velocity system works through aspiration, introducing heated or cooled air into the rooms at a high rate of speed. It creates a gentle suction to mix the old and new air extremely quickly.
