A home furnace provides that much-needed warmth during the cold season. In the dead of winter, most people hardly pay any attention to how it works until one day, they come home to a broken furnace. To maintain it and troubleshoot issues properly, understanding how furnace works helps. Today, we at Air Supply Heating & Air Conditioning would like to take the opportunity to discuss the basics of how the furnace works.

What are the Components of a Forced Air Furnace?

Heat Exchanger: One of the most vital parts of a home furnace is the heat exchanger. Where heat is added to the air is the exchanger and is made up of coils. The heated air is blown into the ductwork by a blower motor.
Ductwork: The heated air throughout your home is distributing with air ducts.
Blower: To direct air from the return ducts into the heat exchanger is the blower. From there, it directs the heated air into the ductwork. During installation, fans are preset.
Burners: Tubes where gas is burned are furnace burners. Fitted with a flame sensor and a gas valve on the burners that help control flames and turn off the gas when a flame is not detected.
Air Filter: Air filters remove allergens and pollutants improving the air quality and is located near the blower motor. Additionally, the air filters protect the motor. Change the filter regularly to guarantee good quality air.
Flue: A flue gets rid of the toxic remnants of the combustion process also referred to as an exhaust stack.
Thermostat: The thermostat helps you control the temperature to your liking. The flames become larger, increasing the temperature when it’s turned up. The flames grow smaller, lowering the heat when turn down.
Heat Pump: Mostly fitted in hybrid heating systems is a heat pump. It reduces heating bills by up to 30% and increases the efficiency of home heating systems. A heat pump works by condensing heat from the outside air and pumping the heat into the home during winter. The heat pump removes the heat from the air in the house and disposes of the hot air outside in the hot months of summer.

How Does a Furnace Heat Your Home?

Through the vent, outside air enters the furnace. An enclosed space in the furnace is the plenum is where the air is stored. The filtered air is then pushed into the burners where the air is heated. The heated air is forced into the ductwork by the blower. The hot air is distributed in your home by the duct work. The process stops until heating is needed again before the process repeats until the heat reaches the required level. Remnants of the combustion process is the flue disposing of noxious flames and carbon monoxide.

Does a Furnace Need Maintenance?

To distribute heat efficiently in your home, a furnace requires regular maintenance. Below are a few steps to help keep the furnace operable from a professional:
1) The air filter needs to be inspected and cleaned.
2) Assess all electronic connections.
3) Routinely lubricate moving parts.
4) On the unit, corrosion is looked for.
5) Inspect the burners to ensure they are operating correctly.
