Is There More Than One Type of Furnace?

There are three different types of furnaces available. There are a few things that factor into which kind will work for you. You should consider your heating requirements, duct work and insulation, the size of your home and number of floors, and your budget. One of the certified technicians at All About Air can assist you in deciding the right type of furnace for your home or office. 

Types of Furnaces


This type of furnace has only one stage of operation. It can either be turned on or turned 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 might not be as effective as other types of furnaces, but they have low cost of installation.


This type of furnace has two settings – full and half speed. This is a more efficient way to heat and provides for better comfort because it can move air at a slower pace. This furnace allows more control over the temperature in your house. This type of furnace also tends to be quieter since it does not operate at full speed all the time.  

Modulating Variable Speed Furnace

This kind of furnace modulates the speed and heat output based on the outdoor temperature and the desired comfort level. This furnace only works as much as you need it, making it the most energy efficient type of furnace. It also provides the best air quality because the fan continually circulates air through the filter even when the furnace isn’t heating. These furnaces often will cost the most up front but will save you money on energy costs in the long run.
