Can A New Furnace Save Money?

January 24, 2023

A new furnace is an investment for your home. New furnace models have improved in efficiency and other heating settings for your convenience and comfort. While costly upfront, the new system can provide many benefits to you and your home when compared to older furnace models. In this blog, we will discuss the difference between new and old furnaces and how a new furnace can save you money.

What’s The Difference Between New & Old Furnaces?

While new and old models of furnaces operate similarly, new improvements have made the two systems differ in many ways. Older furnaces may maintain comfort and properly heat your home, but at what cost each month? Upgrading to a new furnace can save money in the long run while providing many benefits for your enjoyment. Below are three specific differences between old and new furnaces.

  • Fuel Sources
  • Venting
  • Blowers

Fuel Sources

While not always, older furnaces typically use electricity to generate heat. Electric furnaces cost more to operate each month when compared to new model gas furnaces. Gas furnaces are the most common heating option homeowners utilize in the U.S.


Older and newer furnaces differ in the way the unit vents combustible gasses. Older furnaces typically vent gasses through vents that exit out of the roof of homes. Newer furnaces utilize more heat from the gasses produced and require a different venting process. Today’s models of furnaces vent gasses out of the side of homes using PVC pipes.


Typically older models of furnaces contain a fixed-speed blower, which indicates the unit runs when it’s cold and shuts off when it is not. While this is an effective heating method, variable-speed blowers on new furnaces perform more efficiently. Variable-speed blowers operate at different speeds to precisely control the amount of air distributed into your home.

Is A New Furnace Worth It?

If you are thinking of installing a new furnace, you have likely wondered if the investment is worth the expense. Winters in Rockville can be chilly, which is why a functioning heating system is important. Additionally, the low temperatures can result in high heating costs. Simply put – a new furnace can save you money and here is why.

New models of furnaces are highly efficient and can keep your monthly heating bills low. The goal to achieve high efficiency is for all the fuel burned to be turned into heat for your home. However, this is not always the case and where efficiency is lost. If your furnace is 80% efficient, 20% of the fuel input is wasted. The higher efficiency of your furnace, the less you waste and the more money you save. According to the U.S. Department of Energy, heating system efficiency upgrades can cut your fuel bills and your furnace’s pollution output by 50%.
