High-efficiency electric furnace prices

All electric furnaces are high-efficiency (AFUE 100) because they convert 100% of the electricity they use into heating. A home needs sealed ducts and insulation to get the full efficiency of the furnace.

Reduce monthly electric bills with the following energy-efficiency improvements:

  • Energy audit – A home energy assessment costs $200 to $500 to find ways to save money on heating and cooling.
  • Insulation – Installing new insulation costs $900 to $3,000 on average.
  • Upgrading windowsWindow replacement costs $400 to $800 each. Window glass replacement costs $150 to $500 on average for better-insulating glass. Older homes lose 10% to 35% of energy from drafty windows.
  • ZoningHVAC zoning costs $2,000 to $3,500 on average. Zoned houses have 30% lower energy bills through controlled heating and cooling of each room.

Alternatively, heat pumps are the most energy-efficient electric heating system and use only 50% of the electricity an electric furnace does. Heat pump installation costs $3,800 to $8,200 on average.

Mobile home electric furnace prices

Mobile home electric furnace replacement costs $950 to $3,000 installed for 35,000- to 70,000-BTU models. New mobile home electric furnace prices are $450 to $1,500 for the unit only. Mobile home furnaces typically have downflow vents since most mobile homes have ductwork under the floors.

Mobile home electric furnace prices
Brand Furnace unit cost Total cost installed
Alpine $700 – $800 $1,200 – $2,300
Coleman $700 – $1,500 $1,200 – $3,000
Mortex $800 – $1,050 $1,300 – $2,550
Nordyne / Intertherm $650 – $1,000 $1,150 – $2,500
Revolv $450 – $1,150 $950 – $2,650

*These HUD-approved units are only compatible with mobile homes or manufactured houses.

Electric furnaces are the safest heating option for mobile homes because they:

  • Don’t create combustion gases or carbon monoxide
  • Don’t require external vents
  • Don’t have any connected flammable fuel supply

Frequently asked questions

How does an electric furnace work?

An electric furnace works by using coiled heating elements to warm up air before blowing the hot air through the home’s air vents. Electric furnaces run on any electrical power source, including solar power. Some units also connect to heaters and electric heat pumps for more home energy efficiency.

  1. The furnace pulls in cold air through attached and filtered air ducts.
  2. Blower-motor fan sends air up through heating-element coils to make hot air.
  3. Fans force heated air up through the outflow chamber connected to air ducts.
  4. The ductwork system directs the heated air throughout the home.

Electric furnace diagram
Electric furnace diagram

How long does an electric furnace last?

An electric furnace lasts 20 to 30 years, depending on the model, climate, and usage frequency. In comparison, gas furnaces last 15 to 25 years. Investing in a high-quality brand, professional installation, and annual maintenance ensures a longer lifespan.

How efficient are electric furnaces?

New electric furnaces are 100% efficient with an AFUE rating of 100. In comparison, gas furnaces are between 80% and 98% efficient. Electric furnaces are cheaper and easier to install than gas furnaces, but electricity costs may be double natural gas in most regions.

Tips for maintaining heat efficiency:

  • Keep the filters clean.
  • Seal all ductwork properly.
  • Use a programmable thermostat.
  • Plan regular maintenance and checkups.

*AFUE means the “Annual Fuel Utilization Efficiency,” which is the measurement of energy efficiency. This number represents how much energy the unit converts into heat.

Hiring an HVAC contractor

Hiring a licensed HVAC professional is essential for their training in electrical work, sheet-metal modifications, and plumbing to guarantee a safe install. DIY furnace installations are illegal in most places and highly dangerous.

  • Look for HVAC installers certified by a North American Technician Excellence (NATE) organization like the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE).
  • Select licensed, insured, and bonded HVAC contractors experienced with installing electric furnaces.
  • Collect copies of all paperwork: estimate details, heating-load calculations, project plans, billed orders, permits, warranties, and work contracts.
  • Verify that estimates include material, labor, and equipment costs as well as the installation schedule.
  • Compare three itemized quotes from different companies. Beware of the cheapest bids that often mean lower-quality work.
  • Check their reviews on HomeGuide, Google, and the Better Business Bureau (BBB).
  • Settle on a total project cost before signing contracts.
  • Plan a payment schedule instead of making complete payments upfront.

Questions to ask the HVAC installer

  • How many electric furnaces have you installed in this area?
  • Can you list references from your past electric furnace installations?
  • Are all labor and materials fees listed in this estimate?
  • Do you use the Manual J load calculation to size my new furnace?
  • Can you recommend any specific electric furnaces that qualify for a local rebate?
  • Will you inspect my electrical connections and ductwork before the installation?
  • Is my existing ductwork in good condition for connecting to a new furnace?
  • What type of furnace and home modifications can lower my utility bills?
  • Can you give me an ongoing service plan for this new furnace system?
  • What warranties do you offer?
  • Will you provide extra sealing on my ductwork?
  • How long will the installation take?
  • Can you show me plans for new modifications and where the new furnace will go?
  • Will my contract guarantee that I get an electric furnace with the exact make, model number, and energy rating I ordered?
  • Do you offer financing plans?
  • Will you pull all the permits?
  • Do you have Wi-Fi-enabled units to monitor my HVAC system?
  • Will you remove all debris after installation, and does this cost extra?
  • What’s your response time if extreme weather conditions occur?
