Gas vs Electric Heater: Which Furnace Type is Best For Your Home?

Gas vs Electric HeaterComparing heating systems may seem overwhelming, but it doesn’t have to be. For example, comparing the advantages and benefits of gas furnaces and electric furnaces is really about looking at just a few key performance metrics.

You’ll want to consider the cost of your heating appliance, energy efficiency, safety factors, operating costs, and durability, or life expectancy. There are, of course, other considerations, such as warranty packages, physical footprint requirements, and brand differences that may make one system more desirable than another for some people.

As you read through the following comparisons, keep in mind these are generalizations. For example, price considerations that apply to our Metro Express Service customers in the Dallas/Fort Worth metroplex may not apply to homeowners living in Maine or Wisconsin.

Five Key Performance Metrics for Comparing Gas Furnaces & Electric Furnaces

When comparing heating systems within a single brand, you will usually find that:

  • The initial cost of an electric heating appliance is less than a gas furnace.
  • Electric systems on average last 15–30 years, depending on how well they are maintained, while gas appliances have a maximum life expectancy of about 20 years, except in rare cases where you occasionally see a 30- or 40-year-old furnace still going strong.
  • Energy efficiency ratings are typically higher for electric furnaces than gas.
  • The risk of carbon dioxide poisoning due to leaks or system failure comes with all gas appliances. Electric heating systems do not carry this risk and are often considered the safer option.
  • While the clear winner for lowest initial investment is the electric furnace, the utility costs for natural gas are almost always less.

Gas Solutions: Pros and Cons for Homeowners

Depending on where you live, you may be able to choose natural gas or propane to power your gas furnace. Today, many homes are built as totally electric homes, and even if you could get gas lines installed, there may not be a local natural gas or propane supplier. The good news is that gas prices have declined steadily over the past few years, and utility service is expanding as popularity grows. If you’re looking for a heating solution that is the least expensive to operate, you usually find that both electric heat pumps and gas furnaces produce lower heating bills each month than electric furnaces.


  • Provides exceptional heat.
  • Complement both air-conditioning units and heat pumps as part of a year-round heating and cooling system for all types of weather.

  • Heats a home up faster than electricity.
  • Gas burns cleaner than coal, which is sometimes used to generate electricity.
  • Generally, a gas furnace works better in cooler, more humid climates than an electric furnace.
  • Gas prices are going down.


  • The cost of installing gas lines may offset monthly savings.
  • Requires ongoing monitoring of carbon dioxide levels.
  • May have to purchase other equipment, such as an indoor coil.

Electric Solutions: Pros and Cons for Homeowners

People who live in dry climates or areas where natural gas options are not available may prefer electric furnaces over a propane or oil-powered furnaces. While electric furnaces may be more expensive to operate, the initial savings attract some buyers. Electric furnace options are also popular in southern states like Texas, where the sheer power of a gas appliances isn’t needed as much as it is in northern states like Michigan and Maine.
