I had a customer I was rewiring a building for some 20 years ago who
needed a new 7.5 ton HVAC unit on the roof. I wasn't doing systems
at the time so I found a contractor for them who appeared to know what
he was doing. It was a medium sized outfit with a number of employees
and trucks so they had the resources to do a good job. I was only
involved in the electrical work so I didn't pay attention to what the
installers were doing. When the system was started up, cold air blew
out the return air and all the supply lines were acting as returns.
I really enjoyed the fact that they had installed it backwards because
the HVAC company boss had been a little bit too arrogant with me.
