Choosing a new furnace for your home takes a lot of thought—and for a good reason. When weighing the pros and cons of an electric vs. gas furnace, there are several factors that you need to consider. These factors include fuel availability, average lifespans, maintenance, and the electric vs. gas furnace monthly cost. You’ll have this heating system for many years to come, which is why you want to make the best decision.

Let’s dive into the advantages and disadvantages of gas and electric furnaces.

Fuel Availability

When debating between electric vs. gas furnaces, it’s essential to know which fuel types are accessible where you live. While gas is prevalent among homeowners, it’s unfortunately not available all across the country due to limited natural gas lines. If you don’t have access to natural gas, this limits your furnace installation choices.

Unlike gas systems, electric furnaces practically have universal accessibility. If your home has electricity, you will be able to use electric heat. Now that we’ve gotten accessibility out of the way, let’s discuss a more divisive topic: electric vs. gas furnace monthly costs.

Upfront & Operational Costs

Electric and gas furnaces have different upfront and operational costs. Electric furnaces cost less to install, while gas furnaces tend to have more expensive upfront costs. The installation of gas furnaces is more complicated than their electric counterparts.

However, electric furnaces tend to be more expensive to operate than gas units. Why, you may ask? Electricity costs more to run than natural gas. It also takes longer to heat up an entire building. And since electric furnaces often have to work harder to battle cold temperatures, your energy bills might skyrocket. 

As a result, you also may find yourself scheduling electric furnace repair in New Orleans more frequently. However, some electric systems include an electric furnace and a heat pump, which can be a more cost-effective way to heat your home.

For electric vs. gas furnace monthly costs, the operating cost of electric systems may be higher than gas in the long run.

Which Is More Energy Efficient?

Energy efficiency in furnaces and air conditioners is a big deal if you’re trying to save energy. Electric furnaces have AFUE ratings up to 100, meaning they have higher energy efficiency than their gas alternatives.

Overall Safety

You must install carbon monoxide detectors if you have a gas system due to safety concerns. Carbon monoxide leaks, in significant amounts, can have adverse health effects for the members of your household. Additionally, natural gas used for gas heat is combustible, which can cause an explosion (although the risk is very low).

Electric systems don’t have combustible gas, so you don’t have to worry about carbon monoxide leaks.


While we’ve reviewed electric vs. gas furnace monthly costs and other essential factors, there’s one more thing to go over: convenience.

Electric furnaces require little professional maintenance, unlike their gas furnaces, which need regular maintenance to ensure efficiency and safety.

Electric vs. gas furnaces have varying life expectancies. Gas systems can last between ten to 20 years, while electric units can last 30 years. You may have to replace your electric furnace less often than your gas furnace.

The Bottom Line

Now that we’ve discussed electric vs. gas furnace monthly costs, fuel availability, and more, it’s time to make a decision. When it comes to choosing between electric vs. gas furnaces, it mostly comes down to personal preference and your specific needs.
