Not understanding how some electronic controls operate and control a system can lead to misdiagnosing a system problem and costly repairs. It is best never to assume, but rather take the time to do some research and find out exactly how they operate. Guessing is rarely good and generally will lead to a misdiagnosis and cause a tech to replace the wrong part or component.

It’s often said that any company’s greatest asset is its people, and this definitely is true for refrigeration contractors. Sure, the refrigeration industry is heavily focused on products and equipment and technology. And don’t forget chemicals – trying to keep track of all the refrigerant changes is enough to make anyone’s head spin. Yet if equipment is the lifeblood of the HVACR industry, then the people at refrigeration companies are its beating heart. And it clearly is in your best interest -- as the contractor whose name is on the door and on the trucks -- to keep your people as happy as possible.
Of course, reclaimers can only reclaim what contractors and technicians recover, and while the R-22 numbers may never match the hoped-for projections, the industry is already looking to the future and preparing to address new challenges in a post-hydrochlorofluorocarbon (HCFC) world that also is likely facing a phasedown of hydrofluorocarbons (HFCs).
