About Weis Comfort Systems

Serving St. Louis’ HVAC Needs Since 1975

Richard Weis returned from WWII and asked his dad for the keys to their shop, which he reopened as Weis Heating Company. He had a process and a plan to economically install central heating in all new homes with the new blower-driven gas furnaces. The housing boom that followed the war allowed the company to expand rapidly.

Raymond Weis, his brother, joined the company in the mid-50s. In 1974, Rich changed the company's direction and core business. He sold the service and replacement department to Ray who renamed the new business, Weis Comfort Systems. We opened the doors on January 1, 1975. More than 40 years later we are still in the same area.

In the early 80s, brothers Tom & Dan joined their father's company full time. In 1992, they made arrangements to purchase the stock and assets of Weis Comfort Systems, Inc., and in 1995, Ray Weis retired.
