60+ Years Of Serving Southern Illinois
Norman and Betty Williams opened the doors of Williams Air Conditioning and Heating in 1947. As time went on Ted Williams joined his family in 1972 and continued to carry on the family traditions of quality, honesty, and dependable service.
Those qualities are the pillars of the business today as Williams Air Conditioning and Heating, led by Shirley Henson and Randy Humphrey, are serving Southern Illinois customers from I-64 South to Cario, from the Mississippi River to the Ohio River.
The business continues to grow and offers the latest in innovations to keep our customers totally comfortable in their homes and offices. And we do this while making sure they spend THE LEAST AMOUNT OF ENERGY DOLLARS POSSIBLE! With many changes going on in the heating and air conditioning industry, and with energy costs going thru the roof, it only makes sense to put your comfort in the capable hands of a business that has stood the test of time, and has grown to offer the people of Southern Illinois true comfort.
Another key aspect of the Williams team is that all service personnel (technicians and installers) are 100% NATE certified. This means that our customers are serviced by men who value their professions and are constantly learning new aspects of the business and the customers that they serve. NATE certification is a series of grueling tests over a variety of subject matters concerning heating and air conditioning. The Nate certification exemplifies a proficiency in the heating and air conditioning industry achieved by few.
