Page 3: So what is an HVAC Test & Balance Anyway?

Next, an analogy…

Page 4: So what is an HVAC Test & Balance Anyway?

Think about the importance of proper air

pressure in your car’s tires.

Page 5: So what is an HVAC Test & Balance Anyway?

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?

Over-inflation creates less tire contact with the

road & thus reduced handling performance.

Page 7: So what is an HVAC Test & Balance Anyway?

When the tire pressure is uneven, you can feel a vibration & a pulling

toward one side, thus reducing driving comfort.

Page 8: So what is an HVAC Test & Balance Anyway?

Improper inflation results in excessive or

uneven tire wear, which leads to a reduced tire lifespan or even failure.

Page 9: So what is an HVAC Test & Balance Anyway?

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?

Page 13: So what is an HVAC Test & Balance Anyway?

Rush of air at the front door & doors hard to open

Page 14: So what is an HVAC Test & Balance Anyway?

Condensation & high humidity

Page 15: So what is an HVAC Test & Balance Anyway?

Smoke escaping the cooking hoods

Page 16: So what is an HVAC Test & Balance Anyway?

Uncomfortable drafts

Page 17: So what is an HVAC Test & Balance Anyway?

Hot or cold areas

Page 18: So what is an HVAC Test & Balance Anyway?

These are all common symptoms of a building

Page 19: So what is an HVAC Test & Balance Anyway?

So then, how do we get it

Page 20: So what is an HVAC Test & Balance Anyway?

Think of a balance scale… place an object

on one side & add weights to the other until

they are in balance.

Page 21: So what is an HVAC Test & Balance Anyway?

We balance the air going into a building with the

air coming out.
