"Hiring Williams & Assoc. has turned out to be one of the best decisions Iâ ve ever made! From the very start, this experience was excellent! Bruce and his team were professional, kind, and helpful when describing the system we purchased and answering the hundred questions we had along the way. Their attention to detail and all of the little extras one wouldnâ t even expect to receive were provided as if it were second nature to them. And the team worked tirelessly, without stopping until the job was finished. We were happy to have them in our home. These are genuinely good people. Our old boiler was past the point of being dangerous. Smoke filled the basement every time it came on. Anyone could see that we were in an emergency position and had no choice but to replace the old system. Some companies Iâ ve dealt with in the past would have taken advantage of our situation. But not Williams! The price for our new high efficiency heating system was very â veryâ reasonable. Due to our situation, the work was started and completed almost immediately and the service was excellent! My wife and I highly recommend Williams & Associates."

"Joe and his crew did an excellent job installing new boiler and indirect hot water system. I made the decision to convert to gas and replace my 21 year old oil fired boiler. Everything went along smoothly and professionally. Joe kept me informed every step of the process and job was completed on time. I would definitely recommend."

"After another vendor recommended major repairs to a central AC system, so I called Parker Heating and Cooling to get another quote. Although I did not ask for a diagnosis, Jeremy inspected the system and discovered an overlooked minor problem, which he took care of. His diligence and honesty saved us thousands of dollars! Jeremy was very responsive and easy to deal with and checked back to make sure the problem was resolved. These days "five stars" has diminished in meaning, but this truly was excellent service!"

"Perfect as I expected and more. East Coast installed a central air system and a ductless heating and calling system in my house. They were much affordable than their competitor."

"I can't say enough good things about Brian, who took care of this work for me. He returned my call promptly, listened carefully to what I needed, and was able to go out to my house within a few days to look at the space available for the two needed light fixtures. He then gave me excellent advice on the type of fixtures that would fit, and the exact sizees I needed to order, as well as what locations would work best for connecting them to the existing wiring. Using his advice, I was able to order the fixtures, which he then came out again to install. He obviously has good skills, but he was also prompt, efficient, honest, and very professional. I will not hesitate to contact him again when I need any further work done -- thanks Brian!"

"Jeremy sent his colleague Austin to my home a day after I first made contact with JMP Electric to fix the cooked breakers in my electrical panel. Austin arrived at the time Jeremy had specified over the phone and promptly got to work removing and inspecting the breaker blocks. In under 2 hours, Austin had my breaker box buttoned up and running with fresh breakers. That's some excellent service if you'd ask me. Thanks again, men! -Chris"
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.
