Do you know the pros and cons of gas vs. electric furnaces? If not, now may be a good time to research the options before making a decision. When trying to decide between a gas furnace or an electric furnace, the best thing to do is to compare them side-by-side. Each has a set of pros and cons to factor in, but knowing everything beforehand helps you to make a decision that is best for you and your situation.

Gas Furnaces: Pros and Cons

To help you learn more about gas furnaces, let’s look at their pros and cons.


  • Energy efficiency
  • Lower operating costs
  • Lifespan of 15 to 20 years
  • Performs well in cold climates


  • Environmental impact
  • Higher installation costs
  • Complex Installation

Gas furnace efficiency is usually measured as a percentage and indicates how much energy from natural gas is converted into heat. For example, if your furnace is 90% efficient, it means that 90% of the energy from the gas is converted to heat and the remaining 10% can be lost in various processes.

What Makes Gas Furnaces Efficient?

AFUE (Annual Fuel Utilization Efficiency) is a standard measure used to represent the efficiency of a gas furnace. It indicates the percentage of energy converted into heat during a typical heating season. Higher AFUE ratings signify greater efficiency.

In modern gas furnaces, advanced combustion technologies are employed to optimize the burning of natural gas, boosting efficiency by maximizing heat production and minimizing waste. Also, furnaces with variable-speed blower motors can adjust their operation based on your heating needs, ensuring consistent temperatures and increasing overall efficiency through reduced energy consumption, especially in mild weather conditions.

Understanding gas furnace efficiency is critical for homeowners who want to make informed decisions about their heating systems. Improving efficiency not only contributes to energy savings but also reduces environmental impact by optimizing the use of energy sources. When considering a gas furnace, looking for a high AFUE rating and advanced features can help ensure optimal efficiency.

Electric Furnaces: Pros and Cons

Now, let’s look at the pros and cons of electric furnaces.


  • Environmentally friendly
  • Lower installation cost
  • Energy efficiency
  • Fewer safety hazards


  • Higher upfront costs (in some cases)
  • If electricity goes out, so does your heat
  • Can be more expensive to repair (in some cases)

What Makes Electric Furnaces More Efficient?

Electric furnaces are super efficient because they convert almost all the energy they use into heat. Unlike gas furnaces that lose some heat in the combustion process, electric ones turn all that energy into warmth. Plus, they’re generally easier to install and maintain.

Electric furnaces are less expensive to install than gas furnaces and require less routine maintenance. They may also be quieter and more durable over time. An electric furnace can last between 20 to 30 years, while gas furnaces usually last between 15 to 20 years.

Smart Thermostats: Energy-efficient Helpers

The beauty of smart thermostats lies in their seamless integration with other smart home devices, creating a synergy that elevates overall energy management and efficiency. These intelligent thermostats are not limited to specific heating systems; they’re versatile, and designed to collaborate with both gas and electric furnaces.

Before making a choice, it’s crucial to check compatibility to ensure you selected a smart thermostat that harmonizes effortlessly with your preferred heating system, unlocking the full potential of a connected and energy-efficient home. Besides being compatible with both gas and electric furnaces, they also have additional benefits, such as:

Remote Control: Whether you’re at home or away, you can control your thermostat remotely. Forgot to adjust before leaving? No worries—do it from your phone!

Scheduling: Set heating schedules based on your routine. Avoid heating an empty house and ensure comfort when you’re home, all while saving on energy bills.

Adaptive Learning: Some smart thermostats adapt to your behavior over time. They anticipate when you’ll be home and adjust temperatures for maximum comfort and efficiency.

Making the Decision

Choosing between a gas and electric furnace depends on various factors, including your budget, environmental concerns, and regional climate. If you prioritize quick warmth because you live in a cold climate, a gas furnace might be the better choice. However, if you value environmental friendliness and have a more moderate climate, an electric furnace could be the ideal option.

In the end, both gas and electric furnaces have their merits and drawbacks. Assess your priorities, consider long-term costs, and weigh the environmental impact to make a decision that aligns with your heating needs. Whether you opt for the quick warmth of gas or the eco-friendly nature of electricity, make the choice that brings comfort to your home.

Incentives and Tax Rebates

Does upgrading your furnace qualify for tax incentives or rebates? When it comes to tax incentives or rebates for upgrading your furnace, there are often government programs in place to encourage energy-efficient home improvements. Here’s a detailed breakdown:

Federal Tax Credits: In some places, there are federal tax credits available for homeowners who make energy-efficient upgrades, including furnace replacements. These credits can directly reduce the amount of income tax you owe.

Local Utility Rebates: Many local utility companies offer rebates for energy-efficient upgrades. These can come in the form of direct cash incentives, bill credits, or discounts on your utility bills.

State or Provincial Programs: Some states or provinces have their incentive programs. These can include rebates, low-interest loans, or grants to offset the cost of upgrading to a more energy-efficient furnace.

Energy Star Certification: Furnaces that meet certain energy efficiency criteria may qualify for the Energy Star label. This label is a widely recognized symbol of energy efficiency. Some regions offer incentives for choosing Energy Star-certified appliances.

Renewable Energy Credits (RECs): In some cases, upgrading to a more efficient furnace may contribute to renewable energy goals. This could make you eligible for Renewable Energy Credits, providing additional financial benefits.

Local Municipality Programs: Check if your city or town has any specific programs in place. Some municipalities offer incentives or grants for energy-efficient home improvements.
