The Government Says Good-Bye to Older Refrigerant Systems

The Government Says Good-Bye to Older Refrigerant Systems

Beginning in 2010 the US Government has put legislation in place that disallows the sale of many refrigerant products that are used by older air conditioning systems.  Although there is nothing in the legal jargon that requires consumers to upgrade their old equipment, many heating and cooling companies are suggesting that these old devices be replaced by newer ones because refrigerant won’t be available for replacement.  Irwin Arieff from the New York Times explains the need for the legislation:

For years, the refrigerant of choice has been R-22, also known as HCFC-22 (short for hydrochlorofluorocarbon) or Freon 22, a brand name.

But R-22, when released into the atmosphere, eats away at the ozone layer, which shields the earth from hazardous ultraviolet radiation. In 1990, the federal Clean Air Act was amended to prohibit putting newly made R-22 into equipment made after Dec. 31, 2009.

The main replacement for R-22 in residential cooling is a hydrofluorocarbon called HFC-410A. Sold under names like Puron, Genetron AZ-20 and Suva, it was recognized by the E.P.A. as an R-22 substitute in 1996.

However, he also states that:

The government wants consumers to know that they are not obliged to buy any new equipment and has taken steps to try to ensure that there will be enough R-22, either newly made or recycled, to maintain existing equipment throughout its lifetime, Mr. Banks said. “People can continue to use their existing units, and continue to service them,” he said.

Geo-thermal Heat Pumps are the new Heat Pump

Geo-thermal Heat Pumps are the new Heat Pump

With heating and cooling costs reaching new highs, many people are looking to the Earth for answers.  New geo-thermal heat pumps can so dramatically lower heating and cooling costs that many people are pulling out their old equipment for the next generation.  Liz Galst of the New York Times says:

The business for ground-source heat pumps is so hot that when some people driving in and around Seattle see Gerard Maloney’s EarthHeat van, with the company’s phone number on the side, they call from their cellphones. “Really, we have people doing this,” Mr. Maloney said.

Like other energy alternatives, ground-source heat pumps have won new admirers as energy costs have skyrocketed.

The pumps, also called geothermal heat pumps, use the relatively constant temperature just below the earth’s surface — six feet below, in many cases — to draw warm air into a building in winter and remove warm air in summer. Advocates say the systems can save building owners 25 percent to 65 percent on energy costs while reducing carbon dioxide emissions.
