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.
