A furnace is an HVAC component that heats air and distributes it into your house. If you want to install one before the chilly season arrives, use this guide to find out how they work and which models are available.

How Furnaces Work

If the temperature in your home falls below the thermostat setting, a signal is sent to activate the furnace. The air may be heated in a variety of ways, depending on the type of appliance you own. After the air is warmed, it’s sent through the ducts and exits the vents to heat your living spaces.

Different Types of Furnaces

hvacThere are three main types of furnaces: single-stage, two-stage, and variable speed. A single-stage furnace runs at full capacity all the time, meaning it only operates at a high heat output. Although this type of device can warm rooms quickly, it uses a lot of energy to do so. This can be expensive for homeowners living in areas with harsh, cold winters.

A two-stage furnace runs at 65 or 100% output. The lower capacity setting regulates indoor temperatures—it switches to full capacity when the former setting isn’t sufficient. This type of furnace is more energy-efficient than a single-stage model, and it’s quieter because it doesn’t operate at full capacity all the time.

A variable speed furnace contains a fan motor in the system. This component can move at different speeds to control the amount of hot air sent through your house. As an added bonus, the fan will help air filter through the HVAC system before being dispersed, enhancing the indoor air quality. Although this type of furnace is costlier upfront, it’s more energy-efficient than single- and two-stage models.
