Makes me glad I work in multiple trades. I ended up at a medical facility, where i'm doing HVAC, controls, plumbing, electrical, and refrigeration/appliance work. Always busy, and when we DO have an opening, it can sometimes take 3 months or more to find an applicant that meets the needs - makes for some really good job security. Either way, spending some time learning some cross-supporting trades (plumbing, electrical and refrigeration all support HVAC, and many of the skills/knowledge are transferrable, and will help with the other trades). I certainly wouldn't give up on the HVAC trade, but perhaps make yourself a more valuable HVAC tech.
