Just about every HVAC system out there has a low voltage control
circuit, and just about every one of them is 24 volts A/C.
You name it, and it probably uses it: gas furnace, oil furnace, condenser, heat pump, rooftop unit, chiller, water source heat pump, zone valve, even zoning systems use good old 24vac.
It's also one of the first things you check after line voltage when you're troubleshooting a problem, how many times have you muttered to yourself; "let's see, I have 24...
