One Stage Furnace, Two Stage Furnace and Efficiency

Originally published December, updated December 2016

As you consider options for a heating system upgrade, you may wonder what type of furnace will provide improved energy efficiency in your Plainfield, Illinois, home. Winter heating costs can be hefty, but advances in HVAC technology make it possible to cut those utility bills significantly. Additionally, incentives can defray the cost of a heating system upgrade. Modern furnaces come in one, two, and multi-stage options that allow you to adjust the speed according to your needs.

One-Stage vs Two-Stage Furnace

Heating stages refer to the capacity at which a furnace operates. Traditional one-stage units operate at only one speed. This high-capacity operation provides a steady stream of heat. Comfort issues can result from the constant use of a high-heat setting. That harsh stream of hot air can cause dry skin and lead to issues like nosebleeds or chapped lips.

A two-stage unit can operate at a high or low speed. The gentle circulation of warm air in the low stage allows your home’s indoor temperatures to remain constant when the temperature is mild. You can use the higher speed when heating needs increase. In systems with variable speed motors, greater energy efficiency levels can be achieved. However, you will need to work with your contractor to ensure that you find the system that is ideal for your home.

Which System Is Right for My Home?

An HVAC professional should calculate your home’s heating load to determine proper system sizing. Many factors will impact the suitability of one system over another. Your budget will also play a role in determining which system is best for your needs. Bryant’s Perfect Heat systems provide high and low stages for adaptive heating based on climate conditions.

Energy Incentives

You can earn tax credits on eligible furnaces. In addition, with two-stage furnaces, a homeowner can recover much of the investment in a new system through lower utility costs. In just four to five years, most two-stage systems pay for themselves. At the same time, you can expect your new unit to last approximately 15 years.
