No Pressure Here
Legend’s design and home building teams put a lot of thought into sizing the HVAC System for your new home’s square footage so that each space within the home will be properly pressure balanced.
Our teams look at, not only the HVAC size for square footage, but also how the sun and shade will effect the pressure within each room. In fact, Legend’s EarthSmart homes obtain whole house temperature management through strategic placing and sizing, of heating ducts and energy efficient windows.
Mike Goodrich, Legend’s VP and Direct of Production, demonstrates how we account for a myriad of complex calculations when sizing the HVAC system in each home and how taking the time to get it right avoids over-pressurized rooms and allows for better airflow throughout your home.

So Legend Homes spends a lot of time sizing the HVAC System in your home.
We want to make sure that we’ve analyzed, not only the size of rooms in your home, the size of the spaces and the square footage in your home and how much air we need to put into them, but we’re [also] going to consider which way the home faces, where the sun’s going to provide the most natural solar heating, where we’ve got shaded areas in there and our HVAC contractor will do some pretty complex calculations to make sure that we’ve got the right amount of air moving into your home.
Once it’s inside your home we need to make sure it’s going to the places that we need it.
So we’re going to have some nice warm air coming into your master bedroom here for example. It may take a couple ducts to do that. Normally that’s a little bigger room. If we just fill this room with air and you shut the door, which people may want to do in their master bedroom from time to time, we can tend to over-pressurize that room. There’s no where for it to go. [The] path of least resistance for it is going to be to try to go underneath your door.
So that’ll tend to take anything that may be in the air – any dust or other particulates or whatever [and] it’ll scrub those through your carpet and you have seen in homes before where you’ll have a dark line underneath the door to your master bedroom. That’s what that is that air trying to go somewhere else.
We can cut that door up and allow an easier path for that air underneath, but that tends to get in the way of privacy, so we’re just going install a simple duct on either side of the door.
All this is is an opening in the ceiling. The air goes up and it dumps into the bedroom on this side and allows that air (that over-pressurized air) in the master bedroom an easy way to get out into the hallway and we can balance the system completely.
