Airflow & Static Pressure with Matt Bruner & Bryan Orr

In this session at Polar Bear Air Conditioning, Matt Bruner and Bryan Orr break down the fundamentals of airflow and static pressure in HVAC systems. Learn the critical differences between static pressure probes and pitot tubes, understand how to interpret manometer readings, and discover practical troubleshooting approaches for residential systems.

Key Topics Covered:

Understanding static pressure vs. actual airflow measurement
Proper use of manometers and measurement locations
Static pressure budgeting across system components
Real-world case studies and common pitfalls
Practical approaches to diagnosing airflow issues
Tips for communicating problems to homeowners

This is Part 11 of Bryan Orr's comprehensive training series at Polar Bear Air Conditioning. Whether you're new to HVAC or an experienced tech looking to sharpen your diagnostic skills, this session provides valuable insights into airflow fundamentals and system performance.

Thanks for uploading all these videos. Has been great information as someone doing facility maintenance for a data center.

The video is really awesome. Nobody in the field do any thing, not even near to those things, finally i can find somebody, even whom i respect, talking about this. No one I have met in school, much less in the field, is interested and I don't think they even know that there are laws of similarity for fans. Thanks again. I am a learner.

I’m a service tech so I use my manometer mostly for diagnosis. You can tell if you have a restriction in your filter, evaporator, blower wheel, or ductwork without pulling one panel.

With much respect, but everyone was asking and forced you to go off topic and in the end I was left without knowing in which environments the values ​​are very close to the good static pressure drops in each element such as the air filter, evaporator, return and supply plenums, etc. Could you help me with that? So good that the course was going and they always asking questions that have nothing to do with the objective.

Should there be two filters at the unit?

What you said about return size... in pumps, pool, well, booster, ect. The friction loss is much more exponential on the suction side, always size up.... i don't know if this applies to home hvac ducting, but the fundamentals seem the same.

Sir, excuse me if I bother you but I have even gone to the store where I buy air conditioning parts and I have asked for technical information on the supply and return grilles and the air filters and the evaporator coils to know data such as flows and pressure drops and they do not know anything, I do not know where I could find that information, if you could help me where I could find that information I would greatly appreciate it, I am only a self-taught learner, I have my HVAC license but I have not been able to develop in this field as much as I would like, but I continue studying and I have not lost hope of being an excellent technician. Thank you for your videos.

Hello. minute 21.59 you mentioned 002, 003 and 005. what is it really speaking 0.002, 0.003 and 0.005 or 0.02, 0.03 and 0.05, I am sorry Sr but you do need to be more specific because it is not the same. Very good video. I am waiting for your response. thank you.

How many has one … me ! … how many use it regularly…. Only on trouble calls

[ultrafaga]

Use more microphones. The audio sucks. 😐
