The U.S. Environmental Protection Agency (EPA) has not given any indication that it will target R-410A in residential applications, and under the Trump administration, the agency may perhaps be less aggressive than it was under the Obama administration and, therefore, less likely to push for additional refrigerant phasedowns.
Single phasing often occurs in an electric motor when one pair of points on its power contactor fails because of the destructive arcing that takes place each time these points open or close. This arc suppressor is designed for AC power applications that operate between 110-480 V and have a maximum allowable current of 235 A (rms).
How to identify and repair restrictions and damage in the liquid line

In last month’s article, “Inside Filter Driers,” which appeared on Page 18 of the Feb. 6 issue of The NEWS, we covered the internal construction, filtering, and drying materials within a refrigerant filter drier. This month, we’ll deal with troubleshooting, service, and replacement of the filter drier.
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.
Extreme Ultra is a solution designed to repair refrigerant gas leaks by guaranteeing a complete, permanent, and elastic endurance of the system. It’s a mix of components, which are gas- and lubricant-friendly.

In follow-up to the document that Tecumseh issued in January 2016 regarding recommended refrigerants, the company says it is making the required changes to its compressors and condensing units in order to meet the performance, reliability and safety requirements for use with alternatives to R-404A and R-134a refrigerants.
