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