Next, an analogy…

Think about the importance of proper air
pressure in your car’s tires.
![Page 5: So what is an HVAC Test & Balance Anyway?](https://reader030.vdocument.in/reader030/viewer/2022032507/55cf1a0dbb61ebd0308b45a1/html5/thumbnails/5.jpg)
Under-inflation creates more resistance with
the road, which requires more energy/fuel, for
about a 3.3% decrease in efficiency. (per DOE)
![Page 6: So what is an HVAC Test & Balance Anyway?](https://reader030.vdocument.in/reader030/viewer/2022032507/55cf1a0dbb61ebd0308b45a1/html5/thumbnails/6.jpg)
Over-inflation creates less tire contact with the
road & thus reduced handling performance.

When the tire pressure is uneven, you can feel a vibration & a pulling
toward one side, thus reducing driving comfort.

Improper inflation results in excessive or
uneven tire wear, which leads to a reduced tire lifespan or even failure.

Each year, 260,000 auto accidents are attributed
to low tire pressure.(per SAE)

In a similar way, proper pressure is very
important in a building.

How many of the following situations
have you experienced?

Hot or cold areas

These are all common symptoms of a building

So then, how do we get it

Think of a balance scale… place an object
on one side & add weights to the other until
they are in balance.

We balance the air going into a building with the
air coming out.
