We all create our own individual histories every day. At the same time, we become part of a larger history. With that in mind, we asked a few industry colleagues what the most significant changes were that they have witnessed in the HVACR industry.
Bob got a call to go to a convention center where the air conditioning system was not working. It was a 75-ton unit with one compressor. The system was many years old, but had been functioning fine, until now. After checking out the unit, an ohm check showed 0 resistance to ground.
CityCenter, an $8.5 billion resort development on the Las Vegas Strip, may be billed as the largest and most elaborate commercial construction project in U.S. history, but the mechanical systems that manage the indoor environment were chosen based on consistency and simplicity.
Is online buying becoming just as important as one phone call and a pickup at the parts counter?

In the mid-1960s, The NEWS ran a seven-part series on trends in compressor design. The author accurately predicted the future shift that took place in compressor development. So it’s fitting to tune in again to hear what this compressor expert has to say about the history and future trends in compressor design.
As a host of pressures - from demanding consumers to stringent regulations to rising energy costs - continue to bear down on the industry, compressor manufacturers are reiterating that energy efficiency is the best response to these issues.
