THE IMPORTANCE OF BALANCE
The goal of a ventilation system is to balance the exchange of the home’s stale air with fresh outside air while recovering
as much of the heating or cooling energy as possible. If the supply air stream coming in is stronger than the return air
going out — or vice versa — it can have a negative impact on the home and the people living inside.
Too much positive pressure (stronger air coming in) can lead to the cracking of walls or freezing of locks, while too
much negative pressure (stronger air going out) can lead to mold and air quality issues. Having a properly balanced
ventilation system is also required to meet home building codes.
