The Future of App-Based Diagnosis w/ Jim Bergmann (Podcast)

Jim Bergmann gives us a year-end review of all that is happening at MeasureQuick and his predictions for the future of app-based diagnosis. He also covers what's been going on with Redfish, BluFlame, BluVac, Supco, Testo, and Fieldpiece.

Diagnostic tools only work if the buyers understand how to use them. When apps can assist the tool buyers and users with diagnosis, the tool manufacturers can focus more on improving the technology; they can leave the software and education to mobile applications. Implementing gas appliance diagnostic education has been a challenge for Jim and other app developers. However, they are attempting to take app-based gas appliance diagnosis to the next level. The goal of diagnostic apps is to educate technicians about tools and readings and to make diagnoses more comprehensive.

From the start, one of MeasureQuick's major focuses has been accessibility and ease of use. A diagnostic app that gives technicians a seamless way to take readings, store data, and learn about their measurements should be easy to use, so Jim has put a lot of work into making a user-friendly app. So, the next step for MeasureQuick in terms of accessibility will likely be to allow users to share data for remote viewing.

MeasureQuick has incorporated education on the basic refrigerant circuit, electrical components, gas appliances, and vacuum within the app. Soon, Jim would like MeasureQuick to expand into the refrigeration and geothermal sides of the HVAC/R world; he'd also like to implement project notes.

Jim and Bryan also discuss:

Monetizing diagnostic apps
Tying tools into diagnostic software
Wireless range and BlueTooth considerations
Working with programmers
How much might I invest in an app-based diagnosis app?
Third-party quality control
Future-proofing
Project or process-based functions
Integration

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

Chris Hughes and Steve Rogers from The Energy Conservatory discuss TEC’s TrueFlow technology and its crucial role in predicting airflow issues in the sales process, particularly for heat pump retrofits. They explain how the TrueFlow app helps contractors accurately measure both static pressure and airflow in existing systems, enabling them to predict whether proposed equipment changes will work effectively. This is especially vital when considering the growing trend of replacing gas furnaces with heat pumps, as the airflow requirements can differ significantly.

The conversation delves into a detailed example of replacing an 80% efficient 48,000 BTU furnace with a heat pump. They demonstrate how the airflow requirement would nearly double from 652 CFM to 1,200 CFM, potentially causing the static pressure to quadruple due to Fan Law 2 principles. This dramatic increase could lead to significant performance issues if not properly addressed during the system design phase. The experts emphasize that using TrueFlow during the sales process allows contractors to identify potential problems and necessary modifications before installation rather than discovering issues during callbacks.

The discussion also covers the ideal workflow for system assessment and sales, starting with customer comfort evaluation and proper load calculations. It’s important to reduce loads through envelope improvements when possible, particularly in cold climates where heat pump retrofits are becoming more common. Proper system sizing often means going smaller rather than larger, contrary to common industry practices, and the worst HVAC systems are often found in expensive custom homes rather than tract housing.

Key Topics Covered:

TrueFlow technology and its role in system forecasting
Fan Law 2 and its impact on static pressure when changing airflow
Heat pump retrofit challenges and considerations
