Good to Be Green

As Carrier Corporation has learned, while being the first and setting the standard may be difficult, it's always the best.

Over the years, Carrier and its North American Residential operations have been dedicated to preserving the environment. The company knows that heating, cooling, ventilation, and refrigeration are much more than issues of comfort and process, and it recognizes the urgent need to maintain a responsible balance between the comfort created and the world in which we live. As a result, Carrier is the first in consumer's minds when they think of environmentally cognizant HVAC companies.

"We've taken an aggressive and pragmatic stance on the environmental issues since the beginning," Mr. Cook says. "As the efficiency standards have come on board and as the refrigerant issues and purer air quality issues have come into the frame, we've always tried to lead the industry. Our Puron product was out there at least 3 to 5 years before any competitor got serious about doing something about the issue."

Carrier has identified six specific areas that directly affect how it balances its customers' needs with the need for responsible consumption: indoor air quality, sound, air distribution, refrigerant, product efficiency, and size/material reduction. In 1996, Carrier recorded an industry first with the unveiling of a residential split system using environmentally sound Puron(R) refrigerant. Since Puron, an HFC, does not contain chlorine, it does not pose a threat to the ozone layer. Consumers have recognized its benefits, as since 1996, more than 200,000 U.S. homeowners have experienced the comfort, quality, reliability, and most importantly, the efficiency from the product.

Carrier's leadership in alternate refrigerant technology has included:

  • the phase-out of all equipment with CFCs a year before mandates set forth by the Montreal Protocol and the Clean Air Act;
  • the introduction of several lines of residential products that utilize HFCs, which are considered to have less of a global warming potential; and
  • the receipt of the U.S. Environmental Protection Agency's Ozone Protection Award for leadership in product development and technology, recognizing its development of the world's first residential central air-conditioner that uses chlorine-free refrigerant and technology that significantly improves the operating efficiency of commercial air-conditioning "chillers" that use non-ozone depleting refrigerant.

    Carrier's product line with Puron refrigerant includes the WeatherMaker(R) line of air-conditioning and heat pump products, fan coils, and small packaged products such as the 50GL packaged air-conditioner, 50JZ packaged heat pump, and 48GP packaged gas/electric comfort system. Its most recent product, the WeatherMaker¨ two-speed air-conditioner with Puron, was launched last year. The product delivers up to 18 SEER when matched with the appropriate indoor equipment - the first residential unit to do so using an alternative, environmentally sound refrigerant. With two-stage cooling, the air-conditioner operates at low speed 75 to 80 percent of the time, eliminating drafts and inconsistent temperatures caused by single-mode units that alternate between "off" and "high" for very short cycles. The low fan speeds are said to be quieter and use less energy, saving consumers money. And because air is circulated - passing through the system's filter - for longer periods of time, indoor air quality is improved.
