hvac vs sdhv

stlblufanJuly 31, 2012

I am in the planning stages of a total gut renovation of a four story row house / brownstone, roughly 4800sf (1200 per floor).

I plan to make the bottom floor a separate garden unit that will provide rental income. I will occupy the top three floors. I would like to have a heating / cooling system for the garden unit, another for the main floor, and a third for the top two floors.

My question is whether I should install traditional split HVAC units, small duct high velocity units, or a combination (for example, a traditional split system in the garden unit and high velocity units upstairs). Space for duct work is not an issue.

My contractor has suggested that a properly installed SDHV unit is better and more efficient than a traditional HVAC unit. Most of the reviews that I have read online suggest otherwise.

What is your location? How cold are your winters?

My gut reaction says to price out a multi zone mini split for the basement apartment. With added electric baseboard heating. And do traditional ducted hvac on your main space.

This is in Hoboken, NJ. Winters can be cold but nothing crazy.
