I need some advice., I live in a remote part of Washington State, there are no opportunities for schooling anywhere on the map. I am interested in the HVAC trade, and for my question, is there a universally known correspondence school course or online study course that is a considered to be really good and worth the money? I know there is really no substitute for a real apprenticeship, but there are no opportunities where I live, and to support a family quickly I will have to have some knowledge before I can be employable in any other town. I'm too old to start at minimum wage with a family.

Thanks for any info.
