Tickets that raise your pay

• A higher grade boiler license

  Each grade lets you run bigger equipment alone, and each one is worth real money.

• Refrigeration and chiller operator license

  Separate in several cities, and needed to run large cooling plants.

• HVAC (heating, ventilation and air conditioning) controls training

  Modern buildings are run from a computer screen. Knowing the control system makes you hard to replace.

• Water treatment certification

  Boiler and cooling water chemistry is its own specialty and some plants pay extra for it.
