Furnace disconnect switch question

Hi,

Before my father passed away he told me to use the furnace kill switch to disconnect the furnace from the power source and to then wait 24 hours before using the air conditioning unit. We have separate systems for AC and Hot Water Furnace + Radiators.

I never bothered to ask him why this needs to be done, and googling is not helping me out. Is this really necessary, and what could be the reason?

Thank you,
Luka

The only possible reason would be IF the boiler (not furnace) and the air conditioning compressor shared the same power circuit. If so, the air conditioning should have a similar disconnect. The reason for waiting 24 hours would be to energize the crankcase heater in the A/C compressor to boil off any refrigerant in the oil.

I will have to test it somehow. Either way thank you for clearing up the 24 hour mystery.
