If you're a HVAC, electrical, plumbing, or facilities pro, you already know this. The industry has a problem - there aren't enough skilled workers, yet many segements of the market continue to grow, such as commercial building and the retrofit of existing structures to include energy-saving systems.
But just because you're popular doesn't mean you should be complacent. In fact, now is the best time to improve your skills so that you can advance your career--and increase your paycheck.
Many employers look for NATE certification; it's good for HVAC, hydronics, and related specialities. If you're in plumbing, ICC may be worth looking at. Facilities managers almost always need a Facility Maintenance Professional (FMP) certification at some point in their career (see IFMA for more info).
