There’s An App for That …
There are so many mobile apps geared toward HVAC contractors. The question is, which ones are worth your time? Answer: Not all of them for sure.
NCI’s David Richardson has found a number that make great sense for the Performance-Based Contracting™ community and we present those here.
This month’s app is ReportApp from Bacharach, Inc. It reads combustion measurements from Bacharach’s Insight Plus and InTech combustion analyzers (Both analyzers are available in the NCI store) via a QR code. The measurements can then be viewed, saved, and emailed as a PDF.
