"This company is fantastic. I have used them for the past 7 years since relocating to North Carolina and they have always completed the work in a timely, cost effective manner. We have had the privilege of working with the same Service Tech. (David) that entire time. In my experience as a homeowner (35+ years) that is unheard of. David is on time for appointments (or calls is running late or early), quickly responds to emergency heating/cooling situations, and looks for repair solutions that will take care of the issue for the least possible cost. It is reassuring to "know" your tech. and have a good feeling about the job he is doing. We also have an annual service agreement with Duggins. We have two furnaces (one electric and one gas) and two a/c systems. Their annual service fee, in my opinion, is very reasonable. He spends whatever time necessary to do the job right. Our home was new construction and in the first couple of years we had a major repair to the system. Duggins did not do the original install but reached out to the manufacturer to make sure that the warranty work was covered. This may not seem like a big deal, but I was not aware the unit was still under warranty, and would have paid for everything - I do not believe all companies would even check about the warranty. I have no reservations recommending Duggins based on 7+ years personal experience with them!"

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.
