Watsco, Inc. (NYSE:WSO) announced today that Barry S. Logan, Senior Vice President, is scheduled to present at the William Blair 32 nd Annual Growth Stock Conference being held at the Four Seasons Hotel in Chicago on Tuesday, June 12, 2012 at 4:10 p.m. (CDT).

Watsco improves indoor living and working environments with air conditioning and heating solutions that provide comfort regardless of the outdoor climate. Our solutions also promote healthier indoor spaces by removing pollutants from the indoor air that can lead to asthma, allergies and reductions in productivity. Furthermore, since heating and cooling accounts for approximately 56% of the energy consumed in a typical United States home, we offer consumers the greatest opportunity to save money on energy by replacing existing air conditioning and heating systems with more energy efficient and environmentally friendly solutions. There are approximately 89 million central air conditioning and heating systems installed in the United States that have been in service for 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 our competitors as the movement toward reducing energy consumption and its environmental impact continues. We operate from more than 575 locations in the United States, Canada, Mexico and Puerto Rico, with additional market coverage on an export basis to Latin America and the Caribbean. As the industry leader, significant growth potential remains given that our current revenue run-rate is less than 10% of the estimated $35 billion marketplace in the Americas for HVAC/R products.
