Pacific Northwest HVAC Education
The HVAC schools of the Pacific Northwest, focus much more on heating than they do in Air Conditioning. This is because the states of the Pacific Northwest, Alaska, Oregon, Washington, Idaho, Montana, are simply cold more than than they are hot.
With the strongest economy of the area, Washington HVAC Schools are the most prevalent.
If you are willing to head south a bit, away from the salmon and toward the surfboards and bikinis of the south, the Dry Western States offer places to avoid the wet winter, and get your HVAC Education as well.
