Will a gas furnace turn on without gas?

Can I turn my furnace off and on?
If it’s a natural gas furnace that uses a standing pilot light to ignite the burners, then we recommend you shut it all the way off by turning off the gas to it. If you don’t do this, the pilot light will continue to burn throughout the summer, which is a waste of gas.
Should you turn off the pilot light on a gas furnace?
Turning off the pilot lights on gas fireplaces and furnaces when not in regular use can save energy and money. If you switch your pilot light off, your air conditioner won’t have to work as hard to reverse the heating effect of the pilot light. Your furnace only uses a small amount of gas to power the pilot light.
What happens if your furnace is not turned on?
A more worrisome problem occurs when the gas does flow but the furnace in the HVAC system does not turn on. This means the pilot light is likely extinguished and needs to be relit. However, if the air in the home is not first vented, lighting a flame with built-up gas could cause an explosion.
