"Greg came on schedule and discussed the project with us. He suggested LED pancake lights and dimmer. We originally planned to put in lights on either side of the room. He e-mailed a price by the end of the day. It was a fair price but over our current budget. We really only needed the lights on one side of the room (over the new office area), so I asked Greg to revise the estimate. It was not trouble and he did not try to push me into the original quote. We agreed on the price and he scheduled the work. Brennan came promptly and even texted me when he was close by so I could put the dog in another room. He completed the work very efficiently, cleaned up everything and was just awesome really. Everything is wonderful!!! I have found my electrician from now on!!!"

"Chris was very polite. He was punctual and gave me plenty of notice of when he would be here. He installed two huge ductless heat a/c units. He was very knowledgeable and gave me options for different units. I saw him measure at least twice and used a level to ensure everything was level. I loved his attention to detail. He seems extremely trustworthy. I felt very comfortable with him. I will recommend him to anyone I know who needs this type of work."

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.
