Stewart's Heating & Air Conditioning Company was established in 1962 by Harry Stewart. The "Little Green Van" has been an icon of Stewart's since the business was started. Harry passed the business down to his sons, Phillip and Jon Stewart. The business has now passed once more to Brandon Reuter and Dustin Drew. We are based out of Dixon, and now service a 20 mile radius. We service and install heating and air conditioning equipment, both residential and commercial. We also have 24 hour emergency service and work on all makes and models of furnaces and air conditioning equipment.
