How to Choose a Furnace that Best Suits Your Needs

Louisville furnaceYou may be looking to replace a sluggish furnace in your existing home or you may be ready to install one in a new home for the first time. Either way, there are some important facts that can help you decide which furnace may be the best fit for your home. Let’s start by examining the two major types of furnaces.

The Two-Stage Furnace

Based on its name, the two-stage furnace is geared to operate the major elements of the furnace in two different ways. First, this type of furnace will change the burn rate of natural gas, or BTUs (British Thermal Units, a unit of energy) generated. Most of these systems will also change the speed at which the blower fan blows, lowering the speed during the first stage and raising it during the second stage.

The two-stage furnace actually runs on a lower amount of BTUs and runs longer in order to keep your home more comfortable by decreasing the temperature swings when the system shuts off and turns back on.

The advantage most people see in this system is in a more consistent temperature while the system is running. Energy savings is not a real advantage to this type of furnace.

Modulating Furnace

This type of High Efficiency furnace operates with more intensity and also reduces the temperature fluctuations, produces a more consistent indoor temperature, is quiet in operation, and utilizes annual fuel consumption up to 98%. Because fuel is used more efficiently, energy use is reduced and so is cost.

This type of gas furnace combines a modular gas valve with a variable speed blower and is able to adjust automatically, continuously regulating the amount of fuel burned based on the thermostat setting. These systems can maintain a temperature within a half-degree of the thermostat set point.  Standard systems can swing between 4-6 degrees.

Because of its variable speed blower, the temperature slowly ramps up and down providing quiet and efficient air distribution while reducing overall utility consumption.

Being informed can help you choose the furnace that can best accommodate your home’s needs and keep you toasty warm this winter season. Contact VanKleef Heating and Air Conditioning, Inc. with any questions you have about your furnace. We are here to help.
