I’ve been building a few HVAC calculators, and I’d like some feedback from the No Bull crew. They’re free to use, with no login required.
• Filter Pressure & Airflow — Check clean-filter pressure drop and face velocity at your airflow. Search for a specific filter or compare filters, cabinets, and return-filter setups.
https://filters.kalosflorida.com/
• Duct Check — Check duct sizes, room airflow, and return paths in an existing home to help spot restrictions and practical improvements.
https://duct.kalosflorida.com/
• Dehumidifier Sizing — Estimate moisture-removal needs for occupied spaces, sealed attics, and encapsulated crawl spaces, then compare equipment using published performance data.
https://dehum.kalosflorida.com/
This one is also on the HVAC School calculators page:
https://www.hvacrschool.com/calculators/#dehumidifier-sizing-calculator
Each has explanations to help you understand the inputs and results.
Try them with a job you know well and tell me what you think. Do the results make sense? Is anything confusing, missing, or hard to use on your phone?
If something looks wrong, please share which calculator you used, the numbers you entered, and what you expected to see. A screenshot helps.
I’m still refining these, so honest feedback is welcome. Thanks for helping me make them more useful.

@bryanorrThis is a new T-shirt idea that I have for the HVAC school store. What do you think?

@bryanorrTony Gonzalez from Fieldpiece and I are going live tonight, Wednesday, September 9, at 7 p.m. Eastern / 4 p.m. Pacific. We're talking about Building a Business That Lasts: Why Culture Beats Strategy in HVACR. Culture shows up in ordinary moments: an apprentice asking for help, someone admitting a mistake, or a hard conversation with a good technician. How we respond teaches people what actually matters around here. We'll talk about why people stay, professional pride and personal humility, and how kindness and accountability can work together. These things affect everyone on the team, whether you own the business or work in the field. Watch here and bring your questions: https://www.youtube.com/watch?v=tXVzFBhzoKo I'd also like to hear from you here: What has a leader or coworker done that made you want to stay with a company?
