"We had Sean and his team install a full house ductless heat pump system. I cannot recommend them enough. They were friendly, organized, efficient, and were sweet to my zoo of pets. Their work was done beautifully. I am picky about placement and how things look and they knocked it out of the park. I’m very happy with the job they did."

"When I was looking for a new high efficiency furnace, I received several quotes and Sure Temp was almost $800 cheaper than any other Carrier dealer. They were on time and did a neat and effective job of installing the furnace. They made sure that everything was clean and all of the paperwork was simple. I was very happy I bought the furnace and used them. Since that time I had 4 service calls. One was related to a minor issue related to installation that appeared during the winter and was quickly dealt with and three calls were related to an issue outside of their control that was tricky to resolve. They were very responsive in getting to my house and dealing with the issue, sometimes having same day service calls available. They were able to get the issue resolved through alot of research and once it was dialed in I have not had a repeat. They took care of the paperwork for the warranty and I never had to do a single thing. I am very happy with my experience with Sure Temp. Based on my experience with the installation and attentive follow-up service, I recommend Sure Temp.

"Don installed a radiant wall unit which replaced our old out dated natural gas baseboard heat that was ugly and went around the whole perimeter in our family room. The new unit is sleek, just on one wall and puts out a lot of heat. Don was a pleasure to work with and went above and beyond to make sure we were satisfied."

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.
