For 2018: I decided well before now that i would tackle the hvac/r license. Classes start January 8,2018. I have 15 months to complete 36 months,with 12 months in the field. The cost to me will be about 12 thousand dollars,with 5 thousand coming from the dept. of education. Pay scale upon completion: 75k on the high end,55k on the low end. Its going to be a busy year! Happy new year, Mark.
