Some contractors have used them suc-cessfully for years and consider them prac-tical and cost-effective ways to seal small, hard-to-find leaks in systems. Other con-tractors feel strongly that only two things belong in a system: refrigerant and oil. Joseph Kokinda, president and CEO of Professional HVACR Services Inc. in Avon Lake, Ohio, said he has seen it all in his 40-plus years in the mechanical trades, and, based on his experiences, he is not a fan of leak-stop agents. He relayed a story of recently finding a huge pool of leak-stop agent around a missed brazed joint in a large refrig-eration system. The customer’s records showed the system had about 90 pounds of R-404A added to it each quarter since 2004. According to Kokinda, an accept-able leak rate for the HVACR industry should be zero, and the way to achieve ■ See LEAK-STOP | Page 16 COMMERCIAL CONTRACTOR Custom Air Products & Services (Hous-ton) launched its Mobile Tech technician dispatch program.

Through recycling and emissions reduction regulations implemented in the Clean Air Act section 608, the EPA does not require special handling, such as the recovery or recycling, of these refriger-ants based on current evidence that their release would not pose a significant threat to the environment. The question remains: What long-term implications will this have on the refrigerant-recovery industry, which has been built on recovering chlorofluorocar-bons (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. Although the growth rate for natural refrigerants in the Americas will be high, the impact in the marketplace will be rela-tively low until around 2030, according to Robert Hennessy, vice president, refriger-■ See NATURALS | Page 12 Tweet @achrnews www.achrnews.com WATCH ON Is Now Featured On Our Home Page!
