[ endif ] About Us In 1969 Henry E. Johnston started cleaning ductwork evenings and weekends. Working out of his home the first years, part time, with a cleaning truck and a toolbox, the demand for his services continued to increase. As his business began to grow and as did his son, he quit is full time job and began working 24 hours a day, 7 days a week. In 1975, his son Henry K. Johnston began Heating, Ventilation and Air Conditioning school and graduated from MATC in Milwaukee, WI. With the help of his son, in 1978 they formed Johnston Furnace Service Corp Now a third generation has joined the team Matthew Henry Johnston. Matthew graduated May, 2007 from Northeast Wisconsin Techinical College with his degree in Heating, Ventilation, Air Conditioning & Refrigeration. The company has continued to grow for the past 39+ years and has expanded their services in Residential, Industrial, and Commercial.

After 5 months of frustration due to significant no shows when expected, blown deadlines, and not one contracted job completed, we finally pulled the plug. When we told him we did not intend to pay full price since the job wasn't completed, he threatened to put a lien on our house, stating he had 7 liens on other homes and wouldn't even need an attorney to do it. We learned you can't believe anything he says as he flat out lied throughout the entire process, so not sure if he actually has liens on other homes but I would not put it past him. Save yourself unnecessary expense and a LOT of frustration and DO NOT work with him!! I only wish we'd checked into his credentials more thoroughly before cont with him.
