The supermarket industry realized a long time ago that it is impossible to solve environmental problems related to refrigerant leaks using a repair-based approach (i.e., with policies that focus on leak repair and record-keeping). Yet, the U.S. Environmental Protection Agency’s (EPA’s) main regulatory program to address harmful refrigerant emissions reflects a repair-based policy.
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.

Verifying a diagnosis will take additional time, but this is time well spent. It will actually save time and money for both the technician and the customer by reducing the amount of callbacks and reducing the replacement of non-defective components on the job. It will also allow the technician to leave the job with peace of mind, knowing he has made a correct diagnosis.
Extech Instruments has introduced the RD300, a heated diode refrigerant leak detector that pinpoints leaks of all CFC, HCFC, and HFC refrigerants with three levels of sensitivity to leaks as small as 0.25 ounce (7 grams) per year.

A new form of leak sealing has been developed that can deal with a wide range of refrigeration leak issues, saving money for everyone from the cost conscious walk-in equipment owner to the cash strapped college student with a leaky refrigerator.
The GreenChill Advanced Refrigeration Partnership has been providing the refrigeration sector with information on efforts to reduce refrigerant emissions and improve efficiencies of commercial equipment. The partnership also publishes service-related materials, the following of which is excerpted from those files.
