I just graduated from a trade school with A.O.S degrees in HVAC and Building Maintenance. I've only had the pleasure of working with extremely small heating/cooling company on a part time basis for the past year. I've had no call backs on my job applications.

I was wondering if it's okay to post my resume as the problem might lie there or is it just the lack of experience that scares off potential employers?

Where would it be best to look for an entry level and or apprenticeship into residential/commercial settings?
