In 1955, Jane Miller began her career with Rockel Sheet Metal. At that time, there were only two other LENNOX dealers in the entire St. Louis area. Seven years later, Jane, along with associates Al Kuennen and Don Herkenhoff, acquired the heating and air conditioning department of Rockel, including the LENNOX dealership.

The three of them formed AL-DON Service, Inc. AL-DON immediately set out to become an industry leader, establishing the first maintenance agreements in the St. Louis area for HVAC systems. With four annual service dates, AL-DON's customers were able to breathe easier knowing a competent organization was taking care of their homes and businesses.

We have been using AL-DON for 17 years. They have always been professional and reliable. But recently, they went above and beyond!! We had and issue with our furnace and between Leslie, Lisa and Alex the matter was resolved, at an affordable price in less than 72 hours. I also learned a few things that will allow me to better monitor my unit in the future. Thanks AL-DON !
