Old Home With Limited Ductwork? Consider High Velocity Air Conditioning

Installing central air in an older home with limited ductwork can be a challenge. Even if the air conditioning unit can be connected to the duct system, the cold air may not circulate properly, so some rooms may not end up cooling well. If your home has small or limited ducts, high velocity air conditioning may be a more effective alternative to standard central air.

What is high velocity air conditioning?

A high velocity air conditioning system consists of an outdoor condensing unit that draws air across hyper-cooled coils, along with an indoor unit called an air handling unit. The air handling unit is responsible for blowing the cooled air into the home. Connected to the air handling unit is a system of thin, small ducts. These can be placed within the walls or even run along the ceiling if need be. The air is blown out of the air handling unit at a very high speed, allowing it to blast through these thin duct pipes and be delivered to various rooms in your home. This type of system does not integrate with your existing heating system; it's a stand-alone system.

What makes high velocity air conditioning a better choice than standard central air?

When your high velocity system is put into place, your HVAC contractor will run the brand new, tiny ducts in a way that will allow all rooms to be cooled. This is a better choice than hoping that your old, existing ductwork will evenly distribute the cooled air. Altering the existing heating ducts in old homes is not usually an option, and there is rarely room to install new, standard-sized ducts. However, the small ducts associated with a high velocity system will fit in most any space without requiring radical remodeling or demolition of your walls.

What are the other benefits of a high velocity air conditioning system?

This type of system operates quietly. You'll barely be able to hear the air passing through the ducts. In addition to cooling your home, the air conditioner will remove humidity, so you'll have fewer issues with dampness and mold during the warm summer months. High velocity air handling units are also attractive. The air handling unit is typically mounted on the wall where it takes up little space, and the outdoor condenser can be surrounded by a fence or bushes to camouflage it.
