"Our furnace stopped working on a Saturday. I called JMSM when two of the big names in Columbus couldn't help. He came on time, could access the part when the big names said I would have to wait until Monday, fixed it and was even cheaper. I can't give a high enough recommendation for John. We were looking at waiting 48 hours for a furnace repair, in January, when the high was in the 20s, with kids and a baby, and instead it only took a few hours. I will call John at JMSM first next time!"

"Apex Plumbing, Heating and Air Pros, are the place to go. They come out and give you a free estimate and honest opinion. I had them replace my water heater and my furnace, and they did a wonderful job on both. I felt that I got the best deal and I was not taken advantage of because I am a woman. I fully recommend Apex and would not go with anyone else"

Hello. I enjoy using my skills as a journeyman electrician to help homeowners save money with smaller electrical needs that come up. Small projects like kitchen/basement remodels and additions. Ive been doing electrical since 1999 and commercially since 2008.\nFree Estimates.
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.
