As a Journeyman Electrician, I will offer the following advice.

If you are interested in being an electrician, go see the local IBEW or Independent Electrical Contractors Association. In the Electrical field, it is useless to go to school without working in the field at the same time. There are work hour requirements necessary to take state electrical tests. In the other trades, I would seek advice from people in those trades before jumping into school.

As a Journeyman Carpenter (really, insulator - long story), I second what UptonSinclair says here. In my experience from working in construction nothing beats field experience for the trades and some of the best training you'll receive for your license is through the unions. Classwork alone won't get you anywhere. I'm not a huge fan of unions but I have to give credit where credit is due. I'm not certain if this applies to HVAC much, but I have to believe it does to some extent especially in commercial construction.
