Our Proud and Humble Beginnings

 Our family business had it’s start at the dawn of the air conditioning industry in the late 50’s and early 60’s. Back then the company was called Dorans Troop, started by our late Grandfather John Dorans. The company’s focus at the time was geared towards sheet metal fabrication and welding. In the mid 70’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 80’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 that we started offering our first HVAC maintenance plans to our growing customer base. By 1985, our present-day company In-Line Air Conditioning Company was formed. We eventually combined In-Line Metal Fabricators into In-Line Air Conditioning Co. Inc. in the mid 90’s and are still run by the Dorans family siblings Robert, Matt Sr. and Dorothy Gutierrez.

We are greatly value our past and look forward to what’s to come. It’s a great feeling knowing that both our grandfather and father look down upon us and are extremely proud of all we have accomplished thus far.
