What happens to a central air heater when there is no gas?
What Happens With No Gas. A central air system can run without natural gas, but when the heat needs to be turned on it won’t work. The heater side of the system requires gas to generate the flames and subsequent hot air to blow through the system. Without the gas, the system will simply blow cold or existing air without heat.
What happens to central air when natural gas is cut off?
When the temperature setting falls below a certain setting, the gas flow will be turned on in the furnace generating flames, which in turn creates heat. What Happens With No Gas A central air system can run without natural gas, but when the heat needs to be turned on it won’t work.
What happens to the heater when the gas is cut off?
