As a glimpse into our history, we are a 3rd Generation family owned business.  We started as a mechanical contractor located in Salem, OR serving Plumbing, HVAC, Sheet Metal, Heating, Air Conditioning, Fire Sprinkler, Boiler and Mechanical service needs in the Willamette Valley.  Starting in 1948 as an Iron Fireman Oil Furnace Dealership, it quickly grew into a full service Commercial and Residential Mechanical Construction Company.

CJ & Ruth Hansen actively operated the business until 1974.  This is when CJ became highly active in National Industry Association efforts (PHCC). Soon after, he would go on to serve as the National President.  At that time, their son, CW (Bill) Hansen P.E. (OSU 1961, Engineering), took over active leadership of the business. Bill is especially active in the daily operation of the business to this day. Check out our CJ Hansen history for a more in depth look at the company and its background.
