HVAC/R products provide comfort to homes and businesses regardless of the outdoor climate. There are approximately 92 million central air conditioning and heating systems installed in the United States that have been in service more than 10 years. Older systems often operate below today's government mandated energy efficiency and environmental standards. Watsco has an opportunity to accelerate the replacement of these systems at a scale greater than its competitors as the movement toward reducing energy consumption and its environmental impact continues. This is especially important since heating and cooling accounts for approximately half of the energy consumed in a typical U.S. home.
