Although the company as we know it today was established in 1975, the company's roots go back well beyond that date.
It all began back in the early 1950s.
There were three plumbing and heating warehouses all owned by the same man, Harry Yelton.
While the business was mostly plumbing, the also carried a line of heating and air conditioning with the brand name of Inland Heating & Air Conditioning.
It was a brand privately labeled by Mr. Yelton just for his companies.
In time, the branch in Granite City closed and the one in Belleville was sold off.
