Im a 50 year old who desires a career change. Im seriously contemplating about getting into the HVAC field. I have approximately 20 months left before I can retire in my current job. My concern is, am I to old to start in this field and is there anyone out there that would give me an opportunity to work part-time in the interim until I reach retirement. I did take a general course in HVAC a few years back and got my universal refrigeration card. Im located 15 miles South West of Boston.
