Serving St Louis and Illinois for over 80 Years

Richard Weis returned from WWII asked for the keys from his dad and re-opened the shop 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.

Nearly 80 years later, the current Weis generation continues the tradition of providing a quality, affordable HVAC service for our customers. At Weis, "When you live and sleep comfortably, so do we."
