"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

"Our experience with DNA was excellent. As soon as I contacted them, Andrew called and visited us. He quickly inpected our attic, which had had a major rat infestation and extremely old heater ducts. He gave us a reasonable estimate for cleaning and sanitizing the attic, replacing the old insulation, and installing new ducts. The crew of Ivan, Andrew, Amanda and Denicio worked quickly and were very personable, reliable and efficient. They kindly removed all the old boxes stored in the attic which was not part of the original work. We especially liked that Andrew followed up with us after the job was completed, to ensure we were satisfied, and offering to come and fix any problems we might have. We could not be happier with DNA and highly recommend them for any heating issues."

"Fast service. Completed on time. No problems."
Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.
Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.
With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.
The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.
Consulting with an HVAC professional can help you determine the exact size that's right for your home.
An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.
An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
