Gas or Electric Furnace: Which One is Right for Your St. Louis Area Home?

5.0 Rating

small_7186885478When you are choosing a new furnace for your home, you have many different things to consider. But one of the first and most basic decisions that you’ll have to make is what type of fuel source your system will use. Two most common fuel sources for furnaces are natural gas and electricity. Today we’re going to help you choose between these fuel types by talking about the pros and cons of gas and electric furnaces and how to choose which one is right for your home!


Pros and cons of an electric furnace


An electric furnace uses heating elements that are powered by electricity to deliver warm air to your home. An air handler blows air over those heating elements, and the heated air is delivered to your rooms through your ductwork.




Pros and cons of a gas furnace


A gas furnace uses burners that are fueled by natural gas to heat up a metal heat exchanger inside of your furnace. An air handler blows air over the outside walls of the heat exchanger, and the heated air is delivered to your rooms through your ductwork.


    • Gas furnace pros: As mentioned above, natural gas is much less expensive than electricity. As a result, gas furnaces cost much less money to operate than electric furnaces. In addition, gas furnaces are more powerful than electric furnaces. This allows gas furnaces to heat your home faster and makes them more suitable than electric furnaces to handle extremely cold temperatures.



Gas or electric furnace: How to choose the right one for your home


In most scenarios in St. Louis area homes, gas furnaces are a better option than electric furnaces. Even though gas furnaces might be a bit more expensive to install, you will more than make up for that in the amount of money you’ll save on natural gas (as opposed to what you’d spend on electricity with an electric furnace). As mentioned above, gas furnaces are also better at keeping your home comfortable. Although gas furnaces can develop safety issues, they are normally completely safe to operate and you can avoid potential problems by scheduling annual tune-ups and regularly changing the air filter.


An electric furnace is typically only recommended for homes that do not have access to a fuel supply. The only type of electric heating system that we recommend as an alternative to gas furnaces is a dual fuel heat pump, which uses a combination of natural gas and electricity.

Zach H came out because we had asked for a smart thermostat 2 years ago and we’re not given one. i mentioned to him that upstairs is always EXTREMELY HOT and he went up felt it and went above and beyond and racked his brain to fix it. he found the issue and was on top of it immediately for a problem he wasn’t even sent out for. you don’t find many people who do extra service. very thankful. it already feels 10x better!
