There are many occupations and jobs that you can seek and be a good candidate for with air conditioning training. Of course, there are many air conditioning contractors out there needing help almost all of the time. But there are also many corporations that have their own in-house maintenance and mechanical departments. Maintenance and repairs to buildings, homes, and schools all require mechanical personnel. High rise buildings use maintenance departments, and many employ stationary engineers. The air conditioning trade is one of the few trades that overlap with other specialized trades. Air conditioning technicians do A/C, plumbing, electrical, carpentry, and welding/brazing.
