What Is a Furnace
A furnace is a method of heating your home that got its start in early Greece. In that day, a furnace was a clay or stone structure that housed a raging, hot fire used to melt metals and dry clay pottery used as dishes and cups.
Eventually, the clay structure became a metal box that houses a furnace. This box replaced fires in massive fireplaces for heating homes. Today, furnaces run by gas or electricity and are very energy efficient. The modern furnace is safe and effective for providing heat to your home.
How Does a Furnace Work
A furnace forces warm air through vents in your home to keep you comfortable when it is cold outdoors. A gas furnace operates like this:
- Natural gas ignites by the burner.
- The hot flames heat the metal exchanger and exhaust out of the flue.
- The heat exchanger shifts its warmth to the incoming air.
- A blower pushes the warm air through the ducts and through the vents to warm your home.
- An air return pulls the colder air out of the room and returns it to the furnace to be heated again.
An electric furnace works like this:
- An electric furnace pulls air into the heat exchanger.
- In the heat exchanger, the air warms.
- The warm air travels through the air ducts and vents to spill warm air into your home.
- The air returns take the colder air back to the furnace to be warmed, continuing the cycle.
The main difference between the gas and electric furnace is the way each is powered. Otherwise, they operate similarly to maintain the level of warmth you prefer in your home.
Reasons Why Your Furnace Is Not Working
Check the Thermostat:
If you are turning on the heat for the first time of the season, the initial step is to check the thermostat. Next, ensure you set the thermostat to a temperature that will cause it to kick on.
If the furnace is not kicking on, check the sensors on the thermostat for dust that breaks the connection. A programmable thermostat might also show an error.
Check the Blower:
The blower pushes the heat through the ducts and out of the vents. Sometimes, the motor wears down over time, while another reason it is not working is damage from overheating.
Check the Fuse or Circuit Breaker:
An electric furnace can blow a fuse. When the furnace won’t turn on, check the fuse box to see if a fuse is blown. There are several reasons why the connection might be broken, including faulty wiring, worn components, and dirty filters.
Check the Gas Valve:
As a precaution, sometimes a repair service technician turns off the gas valve to the furnace in the summer when you don’t need heat. Check the gas valve and ensure you turn it on, so the furnace gets the gas it needs to operate.
Check the Pilot Light:
Older gas furnaces sometimes have a pilot light that blows out. Check the pilot light to see if it needs to be re-lit. This is a job best left to a professional technician.
Check the Air Filter:
An air filter that is clogged or excessively dirty can also keep the furnace from turning on. When the air cannot come through the filters in the house, the furnace won’t turn on and work properly.
