Types of Furnaces


There are three different types of furnaces available. There are several things that factor into which type will work best for you. You should consider your heating requirements, ductwork and insulation, size of your home, number of floors, and your budget. One of the certified technicians at All Weather can assist you in deciding the right type of unit 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 isn’t as high as the other types of furnaces, but they have a 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 the air at a slower pace. There is more control over the temperature in your house. This type of furnace also tends to be quieter since it does operate at full speed all the time. 

Modulating Variable Speed Furnace

This type 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, which makes 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.
