When I first started working for Plumbing & Mechanical’s sister publication, The ACHR NEWS in 2014, I was often the only woman in the room at industry events. Those first few conferences were just a bit intimidating. In fact, it wasn’t until a HARDI annual conference that I first met other women in the industry — shout out to Colleen Keyworth, director of sales and marketing for Online-Access and immediate past president of Women in HVACR, for her immediate friendship then and for all the years since!

Just like last year, I will stay away from prognosticating about where the stock market will be at this end of the year; instead, I will stick to identifying trends that supply houses will find important in this upcoming year. With all that being said, let's jump right in and review my 2022 predictions.

Working in trenches

Mike Rowe, the “Dirty Jobs” guy, caught a bunch of flak for saying, “safety third.” Seems folks took that to mean Rowe did not consider jobsite safety a priority when, in fact, he was attempting to point out the absurd notion that posted “safety first” signage was a farce. No one is really going to be constantly looking out for an individual’s safety and Rowe was simply trying to convey the message that everyone has to be responsible for their own safety on jobsites.

Dan Holohan: Dry steam is the goal

Things to consider when replacing a steam boiler.

I love all the advances taking place in the world of hydronics, but I’m still seeing plenty of steam systems out there in our older cities, so knowing about dry steam will help you if you’re replacing a steam boiler. The dryer the steam is, the better you’re going to look to your customers.

As the water receded from Lake Mead this past year, all the major news headlines focused on the human remains it revealed. Very rarely did any mention the ecosystem in crisis as trees, fish and other aquatic creatures, birds and other species are dying out as they are left out to dry.
