Based on the NCI man-tra that if you’re not measuring, you’re just guessing, this mod-ule introduces you to the basic principles, terms, and concepts of system performance. It is the starting point for several key goals that include knowing what measurements to take and how to take them, recognizing what test numbers to record, diagnosing based on the results, and more.

In this blog post he explains how statics help you see the HVAC system in a new light, helps you find prob-lems you otherwise wouldn’t know were there, and then explain it to consumers in terms they understand. He boils this down to six steps to make it easier for you to implement.

Is time running out on us? Dominick explains in this blog post. Read it here: ncilink.com/CrossroadsThere’s an App For That ...How many HVAC-based mobile apps are out there? How many of them are legitimate? That is anyone’s guess. But NCI’s David Richardson makes it his business to find those that make the most sense for Performance-Based Contractors™. This month, his pick is the HVAC Check & Charge™ mobile app from Emerson Climate Technologies. This app provides an on-site refrigerant charge calculator for air condition-ing applications. Based on historic sliding cardboard charge calculators, contractors can easily calculate correct system refrigerant charge for R-22 or R-410A. Simply choose Sub-cooling, Superheat, or Airflow, and enter the specified system temperatures along with the latent and sensible environ- mental loads. These values are used to determine the proper system charge. This free Emerson app is available on both the Apple and Google app stores.JULY 2018 7HVACTODAY.COMSo where are the young people? Consider this: because of a lack of Federal and State support for HVAC (or any trade) education, high schoolers continue to be steered toward college degrees by counselors. There is very little promotion of the trades for these youngsters. Our own industry does a poor job of self-promotion.Furthermore, when you do a Google search for HVAC careers, the results are a lot unsatisfacto-ry summaries that paint our industry negatively. They say HVAC offers low-paying construction jobs requiring long hours, cramped conditions, and adherence to confusing codes and regulations.It doesn’t help that the news media loves a good contractor sting story to further blacken our collective eye. Very little coverage is given to the positives this industry provides society. But there should be. The HVAC Industry is vital to this nation. Our technology and services enable Americans to live and work in temperature-hos-tile environments like the Southwest. Our industry keeps food supplies and medicines fresh so they last longer. We help save lives by eliminating combus-tion issues that lead to carbon monoxide poisoning. Oh yeah — the HVAC Industry contributes heavily to overall productivity.So how can you find needed young people to work for your company? Read our Panel Discus-sion on page 16 and see how Performance-Based Contractors are doing it. Don’t understand how performance can be your ticket to more young people? Read Dom-inick Guarino’s article on page 21 that defines what performance is and why it benefits your company and your customers.Where have all the young people gone? They’re out there. Your Performance-Based culture will help reel them in. Have a great, profitable summer. As I write this column, the temperatures here in Cleveland are beginning to soar and the busiest season of the year for most contractors is upon us. It’s also that time of year where contractors struggle to have enough good technicians on staff to handle the increased load and keep customers satisfied.Early in my career, I wrote my first feature story in another HVAC trade magazine. It was in 1984 and focused on a burgeoning commercial retro-fit market that needed a pool of talented techni-cians to handle the growing workload. That pool was nearly empty.In the 34 years since printing that article, not much has changed. Recently, the U.S. Bureau of Labor Statistics (BLS), estimated the current HVAC technician shortage at around 70,000. They also predicted a need for 115,000 new HVACR professionals to meet demand within the next four years!Also, according to a joint industry survey conducted by Sage and the Associated Gener-al Contractors of America (AGC), though many companies see a growing demand, their opti-mism is tainted by increasing concerns about workforce shortages.So what is going on?Let’s start with the age of our field workforce. Today, according to BLS, 72% of them are be-tween the ages of 22 and 55, with the bulk of those in the Baby Boomer set — closing in on the 50-year mark. That means more technicians will be retiring at a faster rate as time goes on.Where Have All the HVAC Technicians Gone?
