When your heating system stops working, or you’re looking for a system upgrade, it helps to know the proper name of the parts. While your HVAC repair company may not expect you to know the name of the specific burner or motor component that stopped working, it would help if you knew the difference between your compressor and your blower. So we’re here to help explain some key home heating system components and clarify what the parts do.
The central component of a forced-air heating system is a furnace. Powered by oil, natural gas, propane, or electricity, a furnace heats the air that is then pushed through ducts via an attached blower. Home heating oil is stored in an external oil tank, fed into the furnace via supply lines, and is filtered before it enters the oil burner.
Boiler-based home heating systems utilize oil, natural gas, electricity, or even wood pellets to generate steam or hot water that is used to heat the home via radiators or coils. Homes that have radiant heating use boiler-based heating systems.
An oil burner is critical for both forced air and steam heat systems. It ignites heating oil, which then heats air or water and can be attached to an oil furnace, water boiler, or a boiler. When oil enters the pump, it is pushed through a nozzle at high pressure and transformed into a mist, which is then lit by a spark provided by an ignition electrode. Without an oil burner, your water boiler can’t produce hot water for showers or food, and your furnace won’t make hot air for heat.
The next heating system component to be familiar with is the filters. There are two sets of filters on your furnace. The oil filter is located along the supply line and should be changed at least twice during the winter. The other system filter is between the return air duct and the blower. Since this filter directly impacts air quality as it traps dust, dirt, and allergens, it should be checked at least once a month and changed as often as necessary, depending on how much debris gets accumulated in it.
Air Handling Units
Your heating system’s air handling unit is more than just a component; it is the central part of the furnace itself. The air handling unit or AHU controls and circulates the air and houses system filters, heating and/or cooling elements such as air coils, control components, humidifiers, and fans. AHUs used in residential homes may only include filters, air coils, and a blower. Large air handling units used for commercial HVAC are housed on building rooftops.
The final component that you should know about is the fan unit, located outside of your home. The fan itself is found on the side or top of the unit. Inside the unit is the compressor, which provides increased air or gas pressure when needed, and the condenser coil, which helps cool the heating system.
