Carrier Corp. recently filed a petition with the U.S. Environmental Protection Agency (EPA), formalizing a request to reclassify a residential condensing unit as a subsystem of a system to extend the manufacturing prohibition to dry R-22 condensing units. The petition urges EPA to reconsider its current position and to issue a new rulemaking.
Some years ago it was common for air-cooled condensers to develop leaks, resulting in unpredictable shorter service life. By studying the causes, it’s possible to come up with solutions. It became obvious that vibration was the major culprit, and thermal expansion/contraction creates some specific problems where the hot gas first enters the coil.

Or you might be somewhere in the middle. These different viewpoints form the basis of what HVAC contractors are looking at as the summer 2011 hiring season heats up.
