There are multiple ways to keep your home comfortable, but one of the most efficient solutions is forced-air heating. This choice is a popular one with homeowners, but many people still don't understand why. Whether you already have a forced-air furnace or you're looking for an upgrade, consider the following before making your final decision.

Common Questions About Forced Air Furnaces

What is a forced-air furnace?

A forced-air central heating system uses air as a heat transfer and relies on vents or ductwork to distribute it throughout the house. The air distribution method is separate from the heating and air conditioning systems, and the return vent carries the air back to the furnace to re-heat it and use it again.

What makes this option popular?

Forced-air systems can improve the air quality of your home because the filters trap airborne debris that makes breathing difficult. Attaching a dehumidifier to these units can also improve air quality further, though the standard model does a fantastic job by itself. This furnace is also a more energy-efficient option because it reuses air multiple times before it's dispersed entirely. Finally, it's a cost-effect option because it's the only HVAC system that combines heating and cooling, and uses the same ductwork for both.

How does it work?

There are multiple ways a forced air furnace can function, depending on the fuel source. For example, natural gas, oil, coal, and propane systems use combustion, electric systems use coils, heat pumps extract heat from the surroundings, and hydronic coils heat water in a boiler. Regardless of the fuel source, all air handlers consist of a blower, air filter, heating element, and various controls.

Why is frequent maintenance essential?

As with any heating system, frequent maintenance is essential for your unit to remain functional longterm. The air filter must be changed every 30 days to 6 months, depending on the type of filter and the number of allergens in your home. This will keep your furnace from overworking, as it'll do if the filter remains dirty. Yearly maintenance is also necessary to service the blower motor, heat exchanger, and inducer motor.
