I need to switch 24VAC (HVAC control) and 120VAC (2A and 10A) with a
PIC. What is the best way to do this? Opto-Isolated TRIAC, SSR?

I like opto isolated solid state relays for my home projects, for their ruggedness and simplicity of a direct logic drive. But for production designs, they are high cost.
I agree. When your are coming to do your own circuit, then you cannot beat an isolating transformer and a SCR/Triac for cost saving. You would have to cide into your pic to drive them with a few kilhertz square wave though.
