- In 1929, John Thielmann founded the family business, servicing boilers and oil furnaces. His son Walter soon joined forces with him, building the business into what it is today. Together, John and Walter became the local representatives of the Lennox Furnace Company. The family tradition continued with Walter's sons, Paul and Tom, who started working in the shop when they were still in grade school. Paul took over the business in 1969 and introduced air conditioning. Tom rejoined the business as a service technician in 1977 and then continued to serve as the company's office manager and service technician. We still take extreme pride in continuing the Thielmann name and great service that Thielmann & Son has been known for throughout the years.
