As any reader of this publication can tell, we are in the age of technology.
This is further emphasized by looking at the list of exhibitors, and the impressive technologically advanced products they were showing, at the recent ASHRAE (AHR Expo) Show. The number and types of thermostats currently on the market are almost beyond the imagination. It is, of course, the responsibility of us, as contractors, to be aware of and familiar with as many of these new technologies as possible. We need to be familiar with all of the different model types that are available through the manufacturers we represent. This was an easy task only a few years ago, with minimal options — an 80 percent furnace, a 90 percent furnace, and air conditioners with a couple of different SEER ratings. Today, it’s a different story with multi and variable-speed motors, different AFUE levels, and many different SEER ratings.
