Mechanical engineer Very good
Very good application This application is very useful.
Replaced paper Tested against paper, seems accurate, best of the bunch? 5 stars for better looks
I use it constantly... Quick duct measurements, airflow calculating, or sizing full duct systems. Works great. Need more HVAC apps like this!
Easy, fast, & accurate better than a ductulator. Use it daily for LEED commissioning. Great tool for field trouble shooting and reviewing plans.
Update for compatibility with OS 5 & 6 devices
Accurately size HVAC equipment! Print a report to obtain permit! Sell more jobs!
