As someone who manages a busy household, I know how intimidating it can feel to replace or install a heating system. Between efficiency ratings, BTU capacities, and all the pricing factors, it can quickly become overwhelming. If you’ve ever asked yourself questions like “How much is an electric furnace?” or “Which electric HVAC unit is right for my 2,000 sq ft home?”, you’re in the right place. Today, we’re going to dive deep into everything you need to know about electric furnaces, including pricing, sizing, installation, and long-term maintenance.
And if you’re curious about a fully bundled HVAC solution, systems like the Goodman 3 Ton 14.5 SEER2 R-32 Bundle provide a clear example of what modern HVAC technology looks like, although here we’ll focus specifically on electric furnaces and their unique advantages.
What Is an Electric Furnace?
Before we get into pricing, it helps to understand what makes an electric furnace different from gas, propane, or oil models.
An electric furnace works by using heating elements to warm air, which is then circulated throughout your home via a blower and ductwork. Unlike gas furnaces, electric systems don’t require fuel lines, combustion, or venting. This not only simplifies installation but also eliminates concerns about carbon monoxide and fuel safety.
Electric furnaces are sometimes referred to as:
-
Electric HVAC system
-
Electronic furnace
-
Electric heat furnace
-
Electric forced air furnace
-
Whole home electric heater
Each of these terms highlights the same basic principle: electricity is the sole source of heat. The flexibility and safety of electric furnaces make them a popular choice for homes without access to natural gas lines or in regions where electric rates are favorable.
How Electric Furnace Pricing Works
One of the first questions homeowners ask is, “How much is an electric furnace?” The answer isn’t simple—it depends on several variables:
1. Furnace Size (BTU Rating)
Electric furnaces are rated by their heating capacity in BTUs (British Thermal Units). Common options include:
-
Small electric furnace – 30,000–50,000 BTU
-
60,000 BTU electric furnace – suitable for medium-sized homes
-
80,000 BTU electric furnace – ideal for 1,500–2,000 sq ft homes
-
100,000 BTU electric furnace – larger homes or homes in very cold climates
As a rule of thumb, a 2,000 sq ft home typically needs an 80,000–100,000 BTU electric furnace, depending on insulation, ceiling height, and local climate. For more guidance on sizing, Energy.gov has an excellent reference for matching BTUs to square footage.
2. Brand and Features
The brand you choose can affect upfront costs. Well-known brands like Goodman, Carrier, and Trane may be more expensive but often offer better reliability, longer warranties, and advanced features like multi-stage heating or electronic air filtration.
Some modern systems combine a furnace with an AC unit in one package, referred to as an electric furnace and AC unit or electric furnace with air conditioning. Bundled systems can reduce installation time and may be more efficient overall.
3. Efficiency Ratings
Efficiency is expressed as AFUE (Annual Fuel Utilization Efficiency), which measures how effectively a furnace converts electricity into heat. Higher AFUE ratings usually mean lower operating costs. While electric furnaces typically have near 100% AFUE because electricity is fully converted to heat, some premium models offer variable-speed blowers for even better energy use and comfort.
4. Installation Complexity
Installation costs can vary significantly depending on:
-
Existing ductwork quality
-
Electrical panel capacity
-
Need for permits or inspections
-
Accessibility and complexity of placement
For a typical upflow electric furnace installation, you might expect installation costs between $1,500–$3,500. Downflow or horizontal furnaces may require additional labor or modifications to your ductwork.
5. Additional Costs
Other factors can affect the overall pricing:
-
Thermostat upgrades – $100–$250
-
Electrical panel upgrades – $500–$1,800
-
Ductwork modifications – $35–$55 per linear foot
-
Permits and inspections – $200–$500
According to HomeAdvisor, the total cost for a complete electric furnace installation can range from $2,000 to $12,000, depending on the variables above.
Types of Electric Furnaces
Electric furnaces can be categorized by airflow design and installation type:
-
Upflow Electric Furnace: Pulls air from the bottom, releases it from the top; common for basements or lower-level installations.
-
Downflow Electric Furnace: Pulls air from the top, releases it from the bottom; often installed in attic spaces.
-
Horizontal Electric Furnace: Designed for tight spaces or closets; airflow is horizontal.
-
Central Electric Furnace: Connected to your home’s ductwork to provide whole-house heating.
Each type has pros and cons depending on your home layout and existing HVAC infrastructure. For a detailed overview, HVAC.com offers helpful guidance on different furnace types and their applications.
Choosing the Right Electric Furnace for Your Home
Selecting the right furnace isn’t just about BTU numbers—it’s about matching your home size, insulation, and climate with the unit’s capabilities. Here’s a practical breakdown:
Small Homes or Apartments
-
Small electric furnace
-
30,000–50,000 BTU
-
Ideal for 600–1,000 sq ft
-
Lower installation costs, simpler electrical requirements
Medium Homes (1,500–2,000 sq ft)
-
60,000–80,000 BTU electric furnace
-
Suitable for 1,500–2,000 sq ft homes
-
Can include electric heater and AC unit for year-round comfort
-
Often paired with a central electric furnace design for even airflow
Large Homes (2,000+ sq ft)
-
80,000–100,000 BTU electric furnace
-
May require panel upgrades
-
Can support whole house electric heater systems or electric forced air systems
-
Ensures even heating for multiple zones
It’s worth consulting with a licensed HVAC professional to conduct a Manual J load calculation—this ensures your furnace matches your home’s heating needs without over- or under-sizing.
Efficiency and Operating Costs
While electric furnaces are generally more expensive to operate than gas in areas with high electricity rates, their simplicity, safety, and low maintenance often offset higher utility bills. Here’s what to expect:
-
Electric furnace for 2000 sq ft home: Typical monthly costs vary by climate and usage, but many homeowners see $100–$200 per month for heating in mild climates.
-
Electric HVAC unit efficiency: High-efficiency units with variable-speed blowers can reduce electricity use by 20–30% compared to standard models.
-
Maintenance savings: Unlike gas furnaces, electric units don’t require combustion inspections, gas line monitoring, or vent cleaning.

Maintenance Tips for Electric Furnaces
Maintaining your furnace is critical to ensuring longevity and efficiency. Here are my top tips:
-
Change or clean filters monthly – Keeps airflow strong and reduces dust accumulation.
-
Check the blower and ducts annually – Prevents blockages and ensures even heating.
-
Inspect electrical connections – Loose or corroded connections can cause inefficiency or safety hazards.
-
Professional service once a year – Annual inspections catch small issues before they become expensive repairs.
Regular maintenance can help your electric furnace last 20–30 years, making it a long-term investment in comfort and peace of mind.
Electric Furnace and AC Integration
Many homeowners combine their electric furnace with an air conditioning unit for full HVAC functionality. These systems, sometimes called electric furnace with air conditioning or electric furnace and AC units, allow you to heat in the winter and cool in the summer with one integrated system.
Benefits include:
-
Single thermostat and control system
-
Optimized ductwork design for both heating and cooling
-
Reduced installation costs versus separate systems
The Bottom Line: Making a Smart Investment
Choosing the right electric furnace requires careful consideration of BTU capacity, efficiency, installation factors, and long-term operating costs.
Here’s what I recommend:
-
Determine your home’s heating needs based on square footage and climate.
-
Decide whether a standalone electric furnace or integrated furnace + AC system is best.
-
Compare brands and models, focusing on reliability, warranty, and AFUE ratings.
-
Include installation, electrical upgrades, and potential ductwork modifications in your budget.
-
Schedule annual maintenance to extend the life of your unit.
For homes around 2,000 sq ft, a 60,000–100,000 BTU electric furnace is typically ideal. Properly sized, maintained, and paired with efficient operation, an electric furnace can provide safe, reliable, and comfortable heat for decades.
