GAS FURNACE VS. ELECTRIC FURNACE: WHAT’S YOUR BEST OPTION?
Thinking about buying a new heating system? If it’s been a while since your last system was installed, you’ll find a wider range of choices, including gas and electric models.
Gas furnaces shine in colder climates where natural gas is affordable. Electric furnaces are simple and dependable, but may cost more to run. Heat pumps are the most efficient electric option, offering steady comfort in regions with milder temperatures.
When comparing gas furnaces vs. electric furnaces, you need clear, practical guidance tailored to your home—not a sales pitch. That’s where Conway Services comes in. We’re here to share the best choices for your home to help you make an informed decision.
HOW EACH SYSTEM WORKS
Wondering, “How does a gas furnace work? How about electric?” Understanding the basics of a gas furnace vs. an electric furnace helps you choose the right system for your home. Here’s a simple look at how each type creates heat and delivers it through your space:
- A gas furnace burns natural gas to create heat, warms a metal heat exchanger, and uses a blower to push that warm air through the ducts. It’s an appealing option for homes in colder climates.
- An electric resistance furnace uses electric heating coils that warm up quickly, and a blower moves air across those coils to heat your home. This type of unit features a simple design and is easy to maintain.
- An electric heat pump pulls heat from the outdoor air and brings it inside, even when it’s chilly. It can also cool down the air during the warmer months.
PROS & CONS OF EACH
GAS FURNACE
Gas furnaces are popular in colder climates because they deliver consistent heat. Despite their popularity, many homeowners may wonder, “How long does a gas furnace last?” This question often comes up when the current furnace is nearing the end of its lifespan and heating installation is in the near future.
With regular maintenance, it’s recommended to replace a furnace about every 8–10 years to maintain safe, efficient performance. You may also wonder, “Does a gas furnace use electricity?” The answer is generally yes, as it requires this type of power to run the blower motor, ignition, and other parts.
If you’re considering a gas furnace, here’s a quick look at the pros and cons.
PROS:
- High heat output that warms your home quickly
- Reliable operation in freezing temperatures
- Easy access to service and replacement parts
- Lower operating costs than electric resistance heat
CONS:
- Requires proper venting and regular checks to help ensure safety
- Needs a natural gas line
- Higher upfront cost for high-efficiency units
- Produces some emissions
ELECTRIC RESISTANCE FURNACE
Electric furnaces heat your home using electric coils. They’re straightforward, clean, and easy to install, making them a practical option where electricity is affordable or when a home doesn’t have a gas line.
PROS:
- Simple installation with no flue or gas hookup
- Quiet operation
- Minimal maintenance requirements
- No combustion or carbon monoxide risks
- Works well in mild climates where heating demand is lower
- Lower upfront equipment cost compared to gas-powered systems
CONS:
- Higher operating costs in areas with expensive electricity
- May require an electrical panel upgrade
- Provides heat only—cooling needs a separate AC or heat pump
- Slower to heat large homes on very cold days
HEAT PUMP (ELECTRIC)
Heat pumps use refrigeration technology to transfer heat rather than create it, making them the most efficient electric alternative. A single system can heat and cool your home, making this option especially effective in mild-to-cold climates when sized correctly.
PROS:
- More efficient than electric resistance heat (more heat per unit of energy)
- Provides both heating and cooling in one unit
- Often eligible for rebates or incentives
- Great option for lowering household emissions
- Works well in many climates with modern cold-climate models
CONS:
- Heating output drops in extreme cold
- May need auxiliary heat or a dual-fuel backup
- Proper sizing and installation are essential for performance
BEST FIT BY HOME/LOCATION
Choosing a gas furnace vs. an electric furnace often comes down to your climate, energy prices, and what your home already has in place. Here’s a quick guide to help you narrow down the best match:
GAS FURNACE
- Ideal for cold climates
- Works well in homes with existing gas service and ductwork
- Great for larger homes needing higher supply temperatures
- Smart choice in regions with low natural gas prices
ELECTRIC RESISTANCE FURNACE
- Best for all-electric homes
- Can accommodate smaller heating loads
- Useful as backup or auxiliary heat
- Practical where electricity is affordable
HEAT PUMP
- Performs well in mild-to-cold climates
- Perfect for homes without gas lines
- Provides heating and cooling in one system
- Good fit for households looking to lower emissions
COSTS AT A GLANCE
A simple way to compare heating costs is to look at how much you pay for the fuel and how efficiently your system converts it into heat. In most regions, natural gas usually delivers heat at a lower cost than electric resistance heating. In contrast, today’s heat pumps can outperform both because they transfer heat rather than generating it.
When homeowners ask, “How much does a gas furnace cost?” the answer varies. Factors like the system size, installation needs, efficiency level, ductwork condition, and electrical or venting upgrades all play a role. The same cost factors apply to electric furnaces and heat pumps.
Gas offers the lowest cost per unit of heat, while an electric resistance unit is generally the most expensive type to run. A heat pump often has low operating costs when installed in a home with a climate well-suited to this technology.
MAINTENANCE & SAFETY
Staying safe and comfortable comes down to routine maintenance, and each heating system has different needs.
GAS FURNACES
The maintenance requirements for gas units include:
- An annual inspection of the heat exchanger and venting
- Functional carbon dioxide alarms in the home for safety
- Regular cleaning of furnace filters to maintain airflow and reduce system odors
ELECTRIC FURNACES & HEAT PUMPS
Electric furnaces and heat pumps need the following maintenance:
- Annual coil cleaning
- Regular checks of refrigerant charge (heat pumps)
- Airflow and electrical connection checks
- Frequent filter cleaning to keep the system running smoothly
