When I got started in the HVAC business half a century ago, I was very fortunate to work for a small firm where I learned a lot about design engineering from some really knowledgeable and practical HVAC engineers. The business we were in was designing HVAC for hospitals, colleges, universities, research facilities, and museums. All of these facilities required very sophisticated central air systems, heating systems, and chilled water systems.
While I loved my job, the people I worked with, and the work we did, I left the company after eight years to work somewhere else to get a different perspective on the HVAC design engineering industry. At that time, I had the opportunity to go to an “engineering-architectural” firm with the emphasis on industrial design engineering where, quite honestly, these systems were far from sophisticated. The company focus was on warehouses and sewage treatment plants.
