High velocity heating and cooling provides whole-house temperature control

The ducts attach to vents that are only six inches in diameter.

When my husband and I first purchased our home, the former owners were heating with space heaters and cooling with portable window units. One of our first priorities was to invest in centralized temperature control. I absolutely hated the appearance of the portable heating and cooling units. They weren’t powerful enough to keep up with demand and definitely weren’t all that energy efficient. However, our home is around two hundred years old and lacks conventional ductwork. The walls and ceilings are still the original plaster and the interior studs have been turned sideways to maximize living space. There’s not enough room to accommodate traditional ductwork. Trying to install a conventional heating and cooling system would have resulted in a huge mess, lengthy project and enormous expense. We needed to find a more versatile alternative for our home. I brought in a licensed HVAC contractor to look over the house and provide recommendations. He immediately suggested a high velocity heating and cooling system. This type of system was designed specifically to retrofit into older homes without causing major disruption or damage. It uses flexible mini ducts that are only three inches in diameter and can be snaked through existing walls and accommodate obstacles such as plumbing pipes and electrical outlets. The ducts attach to vents that are only six inches in diameter. The actual heating/cooling unit is wonderfully compact and can be installed in the attic. The system works through a process of aspiration, introducing the conditioned air at a high rate of speed and creating a gentle suction. This allows it to raise or lower room temperature very quickly. The high velocity heating and cooling system has been ideal for us.
