Hello I'm a stationary engineer from Minnesota and have recently moved to Oklahoma city for family. I have been a boiler operator and mechanic for 8 years. I accepted a job in oklahoma city and as part of it my employeer sent me to a great HVAC program and I obtained my EPA Cert and technical training. Unfortunatly I do not have any previous HVAC experience and my employer has asked me to take car of small appliances and small refrigeration units around the plant. they set me up with all the tools necessary to do this job but i'm still very green and may have a question from time to time. So far I have had very little trouble and i have been reading my notes and books before i work on a piece of equipment so that I know what i'm about to do and don't get hurt or break any Laws. Luckily I have been able to repair all of the machines i have encountered so far. Looking forward to some great advice and gaining some knowledge from all of you!
