Due to the ban in the near future of R-22 based units and the phase out of R-22. PURON is the future. The R-22 systems are going to way of the dinosaurs. The heating and air-conditioning industry has taken action to insure a safe future for our children. By removing the gases from our industry that contribute to the global warming effect and to ozone depletion. Carrier (the worlds largest heating and air-conditioning manufacture) along with Copeland (the compressor manufacture and Allied Chemicals have developed PURON and the high efficient equipment to put it to work or you...PURON is a refrigerant that has earned the GREEN SEAL and ENERGY STAR for being environmentally safe. Carrier has several items to fit your individual needs. Whether you need an air conditioner or a heat pump, Carrier has a full line of energy saving units. We here at Maynards having been factory trained and being authorized Carrier dealer, we have more experience with this new product due to the fact that Carrier was the first to put their PURON unit on the market.

With four years more experience working with PURON than any other manufacture in the United States. Carrier is the clear choice. Call us for your heating and air-conditioning needs. As the demand for the residential refrigerants increases, the production of R-22 will decrease sharply in less than six years. Production is capped at 15 million tons per year from 1996 through 2003. However, actual consumption in 1996 was 12 million tons. Despite the cool summer, consumption increased in 1997 to 12.95 million tons, roughly 85 percent of cap. Beginning in 2004, the HCFC cap will be reduced 33 percent to 10 million tons per year, far below the demand of 1997. As you can see the phaseout of R-22 begins now. The most significant increase in R-22 is expected just prior to 2004, when the production cap is reduced 23 percent below the projected 1998 demand. As R-22 is phased out, consumers who purchased a product containing PURON will benefit due to a lower cost for future service. On the other hand, those who purchased an R-22 product can expect to feel the high price associated with service as the supply of HCFC's is depleted. As the consumption increases and the production decreases, the price of R-22 is expected to skyrocket, just at the case of R-12. As you can see in the chart, the price of R-12 rose dramatically as a result of its depletion. Due to its depletion the wholesale cost of a 30lb cylinder of R-12 increased 650% between 1990 & 1997.
