In 1902, Willis Carrier finished the blueprints for the world's first air conditioner, and in 1914 the first residential air conditioning system was installed. Carrier Engineering Corporation was born in 1915 and since then the Carrier name has become synonymous with comfortable climate control. Carrier air conditioners can be found in millions of homes and businesses around the globe.

It's only fitting that the company that invented air conditioning would offer one of the most innovative and efficient lines of air conditioners available today. Carrier's Infinity Series offers SEERs (Seasonal Energy Efficiency Ratings) of up to 21, the highest available on the market. These units are built with Silencer System II for quiet performance, offer excellent humidity control, and earn high marks for air quality. Two-stage operation provides superior comfort and control, while WeatherArmor Ultra provides protection from the elements for increased durability. There are up to 23 diagnostic checkpoints to facilitate maintenance and repair work. Carrier's Infinity System Control thermostat offers settings for humidity, air quality, fan speed and ventilation as well as 7-day programming for maximum comfort.

Carrier's Performance and Comfort Series offers efficiency at an affordable price. Performance Series units offer up to 15 SEER and Comfort Series units offer up to 14 SEER, both of which are higher than the U.S. Department of Energy's 13-SEER minimum requirement. You'll see the savings in your energy bill every month. All Carrier air conditioning units utilize Puron refrigerant, which is approved by the U.S. Environmental Protection Agency as an environmentally friendly alternative to ozone-depleting Freon. The Performance and Comfort Series utilize a combination of Puron and R-22, a refrigerant with low ozone-depleting potential. Whichever Carrier unit you choose to cool your home, all Carrier air-conditioning units carry a 10-year compressor limited warranty and a 5-year parts limited warranty for added protection.
