Gas Furnace

Is it Cheaper to Have a Gas or Electric Furnace


When it comes to keeping our homes warm and comfortable, the choice between a gas furnace and an electric furnace is a pivotal decision. Both options have their own set of advantages and drawbacks, but one of the most pressing factors that influence our decision is cost. In this article, we will delve into the complexities of comparing the cost-effectiveness of gas and electric furnaces. By the end, you’ll have a clearer understanding of which option aligns better with your budget and needs.

Understanding Gas Furnaces

How Gas Furnaces Work

Gas furnaces operate by burning natural gas to generate heat. The heat is then distributed throughout your home via ducts and vents. The combustion process is highly efficient, making gas furnaces a popular choice for colder climates.

Cost Considerations of Gas Furnaces

While the initial cost of purchasing and installing a gas furnace can be higher than that of an electric furnace, the operational costs tend to be lower over time. Natural gas is generally less expensive than electricity, making it a cost-effective option for heating your home, particularly in regions where gas prices are relatively low.

Energy Efficiency

Gas furnaces are known for their high energy efficiency, translating to lower energy bills. Modern gas furnaces come with impressive AFUE (Annual Fuel Utilization Efficiency) ratings, which indicate how efficiently the furnace converts fuel into heat. Higher AFUE ratings result in less energy wastage and more savings.

Unraveling Electric Furnaces

How Electric Furnaces Work

Electric furnaces, unlike their gas counterparts, use electric resistance to generate heat. This process involves passing an electric current through a resistor, which produces heat. The warm air is then circulated throughout the house using fans and vents.

Evaluating the Cost of Electric Furnaces

Electricity prices can vary significantly, and this directly impacts the cost-effectiveness of electric furnaces. While the initial purchase and installation costs are often lower, the long-term operational expenses can be higher due to the typically higher cost of electricity compared to natural gas.

Energy Efficiency Factors

Electric furnaces tend to have lower energy efficiency compared to gas furnaces. This is because the conversion of electricity into heat is not as efficient as burning natural gas. Consequently, electric furnaces might result in higher energy bills, especially during colder months.

Making an Informed Decision

Initial Costs vs. Long-Term Savings

When deciding between a gas furnace and an electric furnace, it’s crucial to consider both the upfront costs and the long-term savings. Gas furnaces might require a higher initial investment, but their lower operational costs over time could balance out the expense.

Regional Factors

The cost-effectiveness of gas and electric furnaces can also be influenced by your geographical location. If natural gas prices are considerably lower in your area, a gas furnace might be the more economical choice. On the other hand, in places where electricity is cheaper, an electric furnace could make more financial sense.

Environmental Impact

Apart from costs, it’s important to consider the environmental impact of your choice. Gas furnaces emit carbon dioxide and other greenhouse gases during combustion, contributing to global warming. Electric furnaces, while producing no direct emissions, still rely on electricity generation, which might come from non-renewable sources.


In the end, the decision to opt for a gas or electric furnace hinges on various factors, with cost being a significant driver. Gas furnaces tend to have lower operational costs due to the relatively lower price of natural gas and their higher energy efficiency. Electric furnaces, while more affordable upfront, could lead to higher long-term energy bills. Ultimately, the best choice depends on your budget, location, and environmental considerations.


1. Which is cheaper to install, a gas furnace, or an electric furnace?

The initial installation cost of a gas furnace is often higher than that of an electric furnace.

2. Are electric furnaces better for the environment?

Electric furnaces produce no direct emissions, but their environmental impact depends on the source of the electricity they use.

3. Do gas furnaces require more maintenance?

Gas furnaces may require more maintenance due to the combustion process and the need to ensure safety.

4. Can I switch from a gas furnace to an electric furnace?

Switching from a gas furnace to an electric furnace would involve significant changes to your heating system and infrastructure.

5. Which type of furnace is more common in colder regions?

Gas furnaces are more common in colder regions due to their high efficiency and ability to provide ample heat.
