furnace


Can you ruin a furnace by turning it off while it is running?

No. Turn it off when you want to.

If you mean turning it off with the thermostat then no. If you mean turning off the power while its running then possibly. The blower is designed to run after the burners shut off to remove most of the heat from the heat exchanger. If you shut the power off all the time then it could put undue stress on the heat exchanger.
