What is a Furnace?

If you have a forced air distribution system, or central heating system, then you likely have a furnace heating your home. It is widely used in large buildings, especially commercial properties. A forced air distribution system essentially heats air and circulates it through the building via air ducts and air vents. Furnaces can be powered by a number of fuel types including propane, natural gas, or electricity.

Though all furnaces work in a similar way of heating air and blowing it through the building, there are operational differences. Specifically, we will talk about single-phase, two-stage, and variable-speed furnace systems.

Single Phase Furnace

A single-phase furnace is the most basic type of furnace and was developed almost a century ago. It is the least expensive in terms of upfront costs, but the operating costs are higher. This is because the single-phase furnace works in only one "gear." The single-phase furnace is either ON or it is OFF.

When the thermostat detects the temperature has dropped below the set temperature, the furnace starts blowing at full capacity. Because the single-phase furnace is either zero or 100, it can waste a considerable amount of energy.

Two-Stage Furnace

A dual-stage furnace, or two-stage furnace, has an extra setting; it can run on a low setting as well as the high setting. In this system, for instance, if the indoor temperature is only a little colder than the thermostat setting, then the furnace will trigger the low setting. This lower setting uses less energy and is quieter than the high setting or single-phase furnace.

Though two-stage furnaces are more energy efficient and effective, they have a higher upfront cost than the single-phase alternative. Still, they last longer and offer long-term savings.

Variable-Speed Furnace

The most modern furnace is the variable-speed furnace. It is even more precise than the two-stage furnace. This precision and agility involves some of the latest technology and comes at a cost, but the energy savings are greatest. For peak efficiency and comfort, we recommend the variable-speed furnace.
