Announced at the recent Earth Technologies Forum is a new partnership of the U.S. Environmental Protection Agency (EPA), the United Nations Environment Programme, and the Alliance for Responsible Atmospheric Policy on “Responsible Use Principles for Hydrofluorocarbons (HFCs).”
When he was a service technician, Jim Tieken and his coworkers “daily experienced the lack of simple-to-use, efficient, and economical refrigerant recovery equipment.” This prompted Tieken and his colleagues to develop, design, and patent the Spooter II and Spooter 134 refrigerant recovery pump. Tieken’s company, ICOR International, Indianapolis, IN, has expanded to include a variety of refrigerants and refrigeration products.
Even though recovery requirements have been around for more than a decade, questions arise from technicians new to the industry and as the result of changing technology. Here are some frequently asked questions and answers.
Like their counterparts in the U.S., contractors and technicians in Canada have been required to carry government cards to purchase and use refrigerants. When the Canadian Ozone Depletion Potential (ODP) program went into effect in the mid- 1990s, there was every intention of having cardholders undergo upgraded training and a retest every few years. But over the years, the upgrades and retests never came about. Extensions were simply granted. Now, new training and a new test appear to be in the offing.
It is a topic that is widely debated among hvacr contractors. Which is the better way to price a job, time and materials (T&M) or flat rate? Both systems can be successful if done correctly. But more and more service contractors are seeing the benefit in switching their current pricing system to flat rate.
In approving the Senate energy bill, legislators voted for an amendment eliminating language that would have increased central air conditioner and heat pump efficiency by 30% (13 SEER) and instead opted for the U.S. Department of Energy (DOE) to proceed with its expected rulemaking instituting a 20% increase or 12 SEER standard to go into effect in 2006.
