Gas or Electric Furnace: The Great Debate


We’re sure you’ve heard of both types of furnaces, as most HVAC professionals offer at least some service with each type. However, there are major differences between these two types of heaters, and we’d like to get into the nitty-gritty differences between them.

If you’re one of the many lucky customers that are making the decision to invest in a heater today, it couldn’t be a better time. Both electric and gas furnaces in Livingston, LA are extremely affordable and run off increasingly affordable sources of energy. They’re reliable, durable, and are known as the most common furnace for HVAC technicians to deal with. You’ll always be able to find a service professional who is willing to work on a furnace, because furnaces are some of the simplest and the easiest systems to repair.

That being said, let’s dive into the differences and let the debate begin!

Gas Furnaces

While just as common as electric furnaces, gas-fueled systems have unique benefits when it comes to heating your home.


  • Low Fuel Costs. Gas furnaces run on natural gas which is an incredibly affordable and clean-burning fuel that many homeowners have access to.
  • Last Up to 20 Years. These systems are durable and reliable, easily lasting up to 20 years if they’re maintained properly.
  • High AFUE rating. An AFUE rating basically dictates fuel efficiency. Gas furnaces have an incredibly high AFUE rating meaning they function very efficiently.


  • More Expensive. Gas furnaces are initially more expensive than electric furnaces.
  • Safety Concerns. Gas furnaces burn natural gas, and while most models are very safe, they can become a safety hazard when not maintained or repaired properly.

Electric Furnaces

Electric furnaces are modern marvels of efficiency. They’re some of the cheapest available heating systems to run, don’t require any natural gas piping to be installed, and can work in pretty much any house with enough room.


  • Cheaper Installation. Electric furnaces are initially cheaper than a gas furnace. They’re some of the cheapest heaters available on the market.
  • Safe and Quiet. They run slightly quieter and safer than gas furnaces. There’s no combustion process involved, which removes the possibility of a gas leak or carbon monoxide poisoning.
  • Last Up to 30 Years. These systems can last even longer than their gas-powered alternatives.
  • Equally Efficient in Warmer Climates. In warm climates, electric furnaces can function extremely efficiently.


  • Higher Fuel Costs. Natural gas is more affordable than electricity, especially when it comes to heating your home in a cold climate. In cold climates, an electric furnace can rack up some seriously high energy bills.
  • Less Efficient. As we mentioned earlier, in colder climates, an electric furnace is going to use more energy and thus run less efficiently than a gas furnace would (or any other type of heater like a boiler).

The Verdict

In our opinion, it looks like its a tie! Each furnace has its pros and cons but no homeowner should have to limit themselves to choosing one or the other. Sure, an electric furnace might be the only option if you don’t have access to a municipal natural gas pipeline, but if you’ve got access to both—it’s good to think the decision over.
