Types Of Furnaces

There are three different types of furnaces available: Single-Stage, Two-Stage, and Modulating Variable Speed Furnaces. When trying to choose which kind will work best for your home, you should consider your heating requirements, ductwork and insulation, size of your home and number of floors, and your budget. If you are still unsure, one of our G & G Heating and Air Conditioning comfort advisors can assist you in deciding the right type of unit for your home or office.

Types of Furnaces

Single-Stage

Single-Stage furnaces only have one stage of operation — On or Off. This also means it has one running speed, and when it is turned on it is pumping out heat as fast as it can. These types of furnaces are not as controlled, so the comfort level isn’t as good as the other kinds of furnaces, but they offer low cost for installation.

Two-Stage

This type of furnace has two settings, full and half speed. This is a more efficient way to heat and provides for better comfort as it can move the air at a slower pace, and makes for more control over the temperature in your house. A Two-Stage furnace also tends to be quieter since it doesn’t operate at full speed all of the time.

Modulating Variable Speed Furnace

This kind of furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, therefore making it the most energy efficient type of furnace. It also provides the best air quality since the fan can run even when the furnace isn’t heating and thus continually circulate the air in your house through the filter in your system. These furnaces often will cost the most upfront but will save you money in the long run on your energy costs.
