Even in Tampa’s mild winters, it’s no fun to put up with a furnace that causes temperature swings and cold spots. By installing a furnace with two-stage heating, you won’t have to. Furnaces with single-stage heating operate on only one setting, but those with two-stage heating provide more precise temperature regulation.

Two-Stage Heating: A Valuable Technological Advancement

The difference between a one-stage and a two-stage furnace lies in their ability to control heat output. Single-stage heating requires only a fixed gas valve and a single-speed blower motor. While these get the job done, they allow the furnace to run at only one speed. This kind of furnace is either on or off. Two-stage heating requires a two-stage gas valve and a variable-speed blower motor. With these more complex components, the furnace is able to run at two settings: low and high. The low setting is sufficient for milder winter weather, while the high setting is necessary only on the coldest days.

Two Stages Mean Greater Comfort

Choosing between a single-stage and two-stage furnace model is an important decision if you value consistently comfortable temperatures. In the warm climate of the Tampa area, a two-stage furnace will run on low up to 80 percent of the time. This setting offers several advantages over running your furnace only on high.

  • Even temperatures – Two-stage furnaces run at a lower speed for longer periods than one-stage models. They produce a lower, but more consistent flow of warm air that keeps indoor temperatures stable.
  • Energy savings – The lower setting requires less fuel, thereby saving energy.
  • Better indoor air quality – Your home’s air will circulate through the HVAC air filter more often, enhancing your indoor air quality.

But how does a two-stage furnace work to keep you comfortable? Fortunately for you, it works automatically. Your furnace will kick on in the lowest setting first. If the room temperature doesn’t reach your selected thermostat setting within a few minutes, the furnace will kick into high.
