Thanks Dan I have 38 yrs exp in commercial boilers (low and high press ) as well as large recip. chillers, large refrig systems and pneumatic controls. i am retired and have plenty of time to answer what I can
I worked as an instructor for years in the evening, with your exp. you would be invaluable as a teacher somewhere. Remember the good old days when we had to run an extension cord for our drill, before battery drills, before cell phones or even pagers, before DDC controls, those were the days
I can almost make a case that you have to abandon servicing to afford to retire. For example an owner of hundred suite building getting about $200 per month per suite. Seventies' prices. Ask for two dollars per suite monthly to maintain heating system. At least you'll hear laughter. Settle for a dollar and learn how to lose money steadily.
