Subcooling can be a somewhat difficult topic for new technicians starting out in the industry. In fact, few topics garner as many questions from green techs than subcooling does.
“A lot of technicians often ask, ‘What should my subcooling be?’ as opposed to fully understanding what it even is,” said Bryan Orr, cofounder and vice president of service, Kalos Services Inc., Clermont, Florida, and founder of HVACRSchool.com. “The actual range of required subcooling is not that great, so it’s not a super difficult question to answer in a simplistic form, but the actual understanding of what it is and how it functions is more in-depth.”
