Frequently Asked Questions
What HVAC tools does EngineersUniverse offer?
EngineersUniverse offers iOS apps for Manual J residential load calculations, Manual D duct design, Manual S equipment selection, psychrometric chart analysis, ASHRAE 62.1 ventilation calculations, and 3D HVAC system visualization. Kindle reference books cover duct sizing, refrigerant cycles, chiller plant design, and BMS integration.
Does the HVAC Studio include a free 3D viewer?
Yes. The HVAC 3D Building Viewer lets you explore a full commercial building with supply/return ductwork, air handling units, fan coil units, VAV boxes, chilled water piping, cooling towers, and BMS control points — all rendered interactively in your browser.
Which ASHRAE standards are covered?
Our tools and books cover ASHRAE 62.1 (ventilation for acceptable indoor air quality), ASHRAE 90.1 (energy efficiency in buildings), ASHRAE Guideline 36 (high-performance sequences of operation), ASHRAE 15 (refrigerant safety), and ASHRAE Fundamentals Handbook psychrometrics.
Are there HVAC exam prep resources?
Yes. We offer iOS apps for the Mechanical PE exam covering HVAC systems, refrigeration cycles, heat transfer, fluid mechanics, and thermodynamics — aligned with NCEES exam specifications.
