"We AssureĀ 
Your Comfort"

Honesty, Integrity, and
Quality Workmanship

Ted DeCarlo the owner of Assured Air, LTD. comes from a family of entrepreneurs. My grandfather and father both ran small businesses in the Chicagoland area. In 1987 I graduated from HVAC School and was quickly employed by a company in the Western suburbs which concentrated on commercial refrigeration. In 1988 I was hired by a company in the Northern suburbs which concentrated on residential heating and cooling and also specialized in boilers and high velocity air conditioning. In 1991 myself and a co-worker opened a HVAC business in the Northern suburbs, and then in 1993 I left the partnership to pursue the dream of owning my own business. I opened my first shop in LaGrange, IL. I figured this was a great location because of the older homes being remodeled in the area would be ready for central air conditioning. The business grew at a steady rate and after three short years I came to the realization that we needed to expand. We moved our business to a large nearby facility in Brookfield. Over the next 12 years we continued to grow and provided excellent customer service and satisfaction to the Chicago area. We now are located and have a showroom in Willow Springs, IL.

Assured Air, LTD. is dedicated to providing our customers with high quality efficient equipment, a proper installation process at a fair reasonable price. Those three simple rules have been the key to our success and will continue to be the foundation of our growth.
