High Velocity System Replacement

Small Duct High Velocity SDHV Heating and Air Conditioning systems

There are many older, historic homes such as Tudor houses in the suburbs of Philadelphia. When you are looking to install central AC into your older style home, Small Duct High Velocity SDHV is the solution for you!

What Is High Velocity Heating And Air Conditioning?

High velocity heating and air conditioning systems use smaller, flexible ductwork to circulate air throughout your home at a rate 4x faster than traditional AC systems. Because of the small and flexible ductwork, your home's current design does not dictate where the ductwork can go. You, the homeowner, are able to decide where you want it and with little construction or modification to the existing design of your home.
