The HVAC industry uses all sorts of fancy words to classify refrigerant. As such, there are all sorts of complicated refrigerant acronyms: HFC, HCFC, CFC. Let's also not forget the mythical zeotropic, azeotropic, and near-azeotropic descriptors. Let's simplify those. (Though if you want to go back to the basics first, check out this article on […]

The way we use and think of refrigerants is evolving quite rapidly. As we shift towards phasing out ozone-depleting refrigerants and considering alternatives, the future of refrigerants may seem a little uncertain to us. However, one thing is certain. Many HVAC units will continue to rely on the common HCFC, HFC, and HFO refrigerants we […]

In HVAC, we work with thermocouples for temperature measurement all the time, but we may not understand the difference between a thermocouple and other types of temperature measurement sensors. A thermocouple is just two different types of metal connected at a “junction” that generates a small voltage with a temperature change. Older furnaces would often […]
