When a gas furnace is blowing out cool air instead of heat, many homeowners try to troubleshoot their furnace before calling a professional. Since there are various reasons why this furnace trouble can occur, sometimes the problem can be fixed by the homeowner and other times a technician who specializes in Furnace Repair Services in Endicott NY must be called. Homeowners can read the information below to learn more about the reasons for cold air blowing out of a furnace.
Wrong Thermostat Setting
If the gas furnace control is placed on an incorrect setting, the furnace may blow out cool air. Homeowners should make sure the furnace thermostat is set to the auto setting so that it blows out warm air. If the thermostat is on the fan setting, it draws the cool air from the basement up through the vents. When homeowners set the control to the on position, the fan constantly blows even when the heat shuts off, which makes it feel colder in the house.
Clogged Air Filter
Another troubleshooting tip for homeowners is to check the condition of the air filter in the gas furnace. When the air filter becomes clogged with excessive dirt and dust, it blocks the warm air flow from the furnace and the furnace may shut off automatically as a safety precaution. Homeowners should look at the air filter regularly and put a new filter in the furnace if the old one is dirty.
Dirty Flame Sensor
Homeowners who have a gas furnace must also make sure that the flame sensor doesn’t get dirty. If there’s too much grime buildup on the sensor, the gas burner will keep going out instead of staying lit. This is most likely the problem when the heat from the furnace starts out warm and then quickly gets cold. A technician who specializes in Furnace Repair Services in Endicott NY can come to the home and clean the flame sensor in the gas furnace.
