Mean HVAC BS Tools is a utility suite for HVAC and building science professionals, providing specialized calculators for air properties, duct sizing, and insulation R-values on iOS.
The App DNA
What makes this app unique?
The app removes the cognitive and time cost of manual psychrometric and duct-sizing calculations, allowing technicians to perform inspections with higher precision and speed.
For HVAC technicians and building science professionals who require field-ready calculators for air flow, thermal resistance, and ventilation compliance.
What does it look like?
Key features
Calculates air flow volume, diameter, friction rate, or velocity for round or rectangular ducts.
Provides air properties for single and mixed streams, including humidity unit conversion.
Estimates wall R-Value using infrared surface and ambient temperature inputs.
Calculates ventilation CFM requirements based on the ASHRAE 62.2-2019 standard.
How much does it cost?
Monetization relies on a one-time purchase model to unlock the full utility suite, replacing recurring subscription pressure with a permanent access fee.
Velocity

The Analyst's Read
Key takeaways for Mean HVAC BS Tools
Where is it heading?
The HVAC utility market is shifting toward specialized, high-accuracy tools that integrate directly into energy audit workflows. Mean HVAC BS Tools is well-positioned to serve this segment if it maintains its focus on accuracy, but the lack of recent feature updates leaves it vulnerable to rivals with faster development cycles.
- The shift to a one-time purchase model aligns with professional user preferences, potentially increasing long-term retention and reducing churn pressure.
- The current maintenance-mode release cadence suggests a focus on stability rather than feature expansion, which may limit growth against more active rivals.
The SWOT
- Automated psychrometric conversions remove manual math burdens during site inspections
- IR Wall Insulation calculator provides a defensible barrier via specialized building science workflows
- Expansion into international unit standards (SI) could unlock markets currently underserved by IP-only tools

The lack of a subscription model is not a weakness…
Read the full takeSince the last report: The app's competitive profile shifted from a focus on domestic utility to identifying international expansion as a key growth vector. The lack of SI unit support is now recognized as a material barrier to entry for global markets.
Bottom line
The transition to a one-time purchase model establishes Mean HVAC BS Tools as a permanent utility for professionals, but the current maintenance-mode cadence risks losing ground to rivals. Expanding into SI units would unlock international markets that IP-only tools currently cannot serve.
