Working in Central Wisconsin. I spent 20 years as the HVAC guy for a plumbing/heating company, but got the 'royal boot' in late 2007. Two years of job applications proved that a 55 year old guy wasn't going to get hired, so I formed the LLC and went on my own.
I do heating and a/c, and love doing elaborate control systems, but still do the mechanical relay logic circuits, and have not learned the digital stuff. I might, haven't decided yet.
I am about the last guy around here that loves residential size oil burners. Everybody else just holds their nose and tries to convert 'em to gas.
Looking forward to learning stuff from here, and maybe even helping sometimes.
