Diagnosing an air conditioning system isn’t easy. A service technician must be a trained professional to diagnose a system efficiently and correctly — no longer can a tech rely on rules of thumb for coil temperatures or pressures.
The next time you’re faced with a choice of whether you should take some extra time and additional measurements, do the right thing. Take the time to do it right and find the true problem the first time.
A total of 148 exhibitors showed off their latest advances in all types of industrial refrigeration at the International Institute of Ammonia Refrigeration (IIAR) 2016 Industrial Refrigeration Conference and Exhibition in Orlando, Florida. Here are a few of the highlights.
George “Butch” Welsch, the 74-year-old owner of the St. Louis-based Welsch Heating & Cooling Co., was recently honored as the ACCA 2016 Residential Contractor of the Year during the ACCA 2016 conference in Charlotte, North Carolina.
The refrigerant recovery and reclamation sector is striving to keep up with the changes taking place in the world of refrigerants, which means it is constantly creating new products to seamlessly adapt to the latest batch of regulations and refrigerant phaseouts.
Some contractors have used leak-stop agents successfully for years and consider them practical and cost-effective ways to seal small, hard-to-find leaks in systems. Other contractors feel strongly that only two things belong in a system: refrigerant and oil.
What long-term implications will this have on the refrigerant-recovery industry, which has been built on recovering chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) — refrigerants that are increasingly being phased out? The answer: Change is on the horizon, but demise is not imminent.
Contractors have a wide range of choices when it comes to properly equipping their technicians to perform safe, efficient refrigerant recovery. Here’s a look at some of the latest equipment and services.
