High Velocity A/C

[JCsPlumbing]

I was watching TOH and Trethewey was showing what he referred to as "high velocity A/C" or something to that effect. Little 4" round registers and I could swear he said no return. I don't know anything about A/C but it seemed new to me.

Why would this be used and is something we're going to see more?:confused:

Its used in houses around here that do not have ductwork. Easier then installing ducts throughout. It is pretty expensive.

They definatly do have a return. They tend to be expensive to purchase though less time consuming to install so it sort of balances out. If not installed correctly they can also be a bit noisy and even if they are installed correctly they make more noise than conventional systems do.

Manufactured by Unico. A niche product for limited access applications. Only avaialbe in heat pump or cooling only. If a heat pump doesn't make economic sense in your area, then you would need an alternate heating source.
