Our Proud and Humble Beginnings

 Our family business had its start at the dawn of the air conditioning industry in the late 1950’s and early 1960’s. Back then the company was called Dorans’ Troop, started by our late Grandfather John Dorans. The company’s focus at the time was sheet metal fabrication and welding. In the mid 1970’s our father, John Dorans Jr., branched out on his own and formed In-Line Metal Fabricators. Again, the company’s primary focus was sheet metal fabrication and ductwork installation. The company had a few service technicians to primarily handle start up and warranty work for the systems that were installed. This is where our current President Robert Dorans started working in the business as a service tech.

In the early 1980’s, our family recognized that there was a growing need for HVAC service and maintenance as more and more central systems were being installed in businesses. It was at that point in time that In-Line started offering our first HVAC maintenance plans to our growing customer base. By 1985, our present-day company, In-Line Air Conditioning, was formed. We eventually combined In-Line Metal Fabricators into In-Line Air Conditioning Co. Inc. in the mid 1990’s and are still run by the Dorans family siblings Robert Dorans and Matt Dorans Sr.

We greatly value our past and look forward to more success to come. It is inspiring to know that both our grandfather and father look down upon us and are extremely proud of all we have accomplished thus far.
