Gas Vs. Electric Furnaces: What Are the Differences?

Winters in Central Indiana can be long and brutal, and a properly functioning furnace is a necessity to keep you and your family warm and cozy indoors.

If your current furnace is more than 15 years old and needs frequent repairs, it’s time to replace it with a newer, more energy-efficient model. But what type of furnace should you buy? While some homeowners utilize propane and oil furnaces, the vast majority of Indianapolis homeowners either have natural gas (49%) or electric furnaces (34%), according to

The right furnace for your home depends on several factors that we’ll discuss in our most recent blog. We’ll help you weigh the pros and cons so you can make an informed decision.

Differences and Similarities Between Gas and Electric Furnaces

Whether you choose gas or electric heating systems, they are both forced-air heating systems, which means they heat air directly and distribute that air through a series of ducts throughout your home. Both types of furnaces are popular choices among Indianapolis residents.

Let’s take a look at some of the similarities and differences between gas and electric heating systems.


New gas furnaces typically cost more to buy and install than electric furnaces. According to FIXR, the average cost to install a new system in a 2,000 square foot home is $4,500 to $6,000, while an electric furnace will cost a homeowner about $2,000 to $4,000.

However, electricity typically costs more than natural gas in most areas of the country, so owners of gas furnaces will recoup their money over time with lower energy costs compared to an electric furnace. With increased energy efficiency, you’ll also notice an increase in energy savings in the long run.

If you own a smaller home in a warmer climate, for example, it may make more sense to buy a less expensive electric furnace because you won’t use it as frequently, which allows you to save energy in the long run. But if you own a larger house in a cold winter climate such as Indianapolis, you end up saving significantly more money over the course of your gas furnace’s lifespan compared to that of an electric furnace. If your Indianapolis home has access to natural gas, we recommend purchasing a gas furnace.


Gas furnaces are easier and less expensive to install, as gas furnaces are larger and more intricate systems. Unless you have extensive experience installing equipment, it’s advised to hire a certified heating and cooling contractor for installation services.


In many cases, electric furnaces may last 20 or more years, while a gas furnace’s lifespan is typically 15 to 20 years.


Both types of furnaces require annual maintenance to perform at high efficiency. An annual tune-up will clean the interior components and find any potential problems that may lead to serious repairs down the road.


Because a gas furnace system combusts fuel, they produce carbon monoxide, which can be harmful and even deadly if a leak occurs. Carbon monoxide leaks from combusted fuel can most commonly occur due to a crack in the heat exchanger. This is why electric furnaces tend to be the safer option. However, gas furnaces are also a safe option as long as regular maintenance is performed on the heating system, lowering the likelihood of a carbon monoxide leak.

Energy Efficiency

Gas furnaces and heaters use less energy to heat the same amount of space as do electric furnaces, and they can also heat homes quicker. Electric furnaces, meanwhile, take more time to heat up as a series of coils are used as its heat source. In climates with cold winters, electric heaters can take even longer to homes. Electric heaters are also more prone to wear and tear as they try to keep up with the heating demands in colder parts of the country such as Indianapolis.
