With a few measurements or design numbers and some quick math, you can estimate the influence outside air has on a system.

New skills and test instruments may look like a predator to employees if they don’t understand why they’re important.

Ductwork education is vital to ensuring comfort, allowing for the delivery of the most efficient and cost-effective air quality solutions.

Let’s look at five hidden reasons HVAC systems might not keep up when the temperatures get hot, how to test for them, and potential repairs.

AMCA International revised ANSI/AMCA Standard 610, Laboratory Methods of Testing Airflow Measurement Stations for Performance Rating.

What if there were a quick and simple way to anticipate what would happen to static pressures if you increased or decreased airflow?

The good news is that once you measure static pressure, you can estimate fan airflow in less than 30 seconds with the right information. Once technicians understand that static pressure testing gets them to fan airflow, they will see why it is important to measure it on every call.

You might wonder, “Why can’t I just use a duct calculator and tape measure to identify duct repairs?” You could, but that means making a lot of assumptions and wasting valuable time.

Airflow balancing has typically been limited to commercial HVAC, but there is a growing demand and opportunity to bring this practice to residential HVAC.

Airflow is a general term that’s easy to misinterpret. When I first learned about airflow, I had to classify it into four values that made sense to me. The easiest options are the measurement location or source of the airflow reading.
