"Canâ t say enough goods things about Onofreo Home Comfort Systems. Itâ s all in the name , Home Comfort. This is the second time I had the pleasure of using their great service. From start to finish, from Kelly at the office , to all the service men and women, to the owner Mark himself, this team is amazing at what they all do. Customer service , simply amazing, and their work is impeccable. They installed a new heating system transfer from oil to natural gas. What ease they made it, again start to finish. When I needed them again to help move some pipes to help with a renovation they were there once again pleasant as ever like weâ ve been good friends for a long time. This is how you should do business, friendly , experience, accommodating, reasonable if not amazing price , and all around great work at the end of the day. Would 1,000 percent recommend to anyone with a home with heat or air. I am using them for air now as well , when you find a good thing stick with it , I did ."

"Scott was wonderful to work with. He first tried to give me a self fix over the phone to same me a maintenance call. This did not work so I called Scott back to schedule an appointment. Scott came out the following morning and identified the issue was more complex after his own inspection. He fixed the issue and gave me some tips on self maintenance for my Heat Pump heating and cooling unit. I would highly recommend Scotti Mechanical Service and will definitely using Scott for future routine maintenance and/or other issues with my heating and cooling system."

"I hired northeast heating and cooling to replace my aging heating A/C system. This was a fairly large job, seeing it was a Multi floor house with two independent systems running both upstairs and the main floor. They also explained to me how adding a heat pump system to the house would help make heating my house less expensive during fall and spring. They replaced the entire upstairs duct work and reconfigured the entire house to run balanced and efficient. I couldn't be any happier with the work that was done in the house I would highly recommend them. Thank you Guy's for your hard work and dedication to get this system working amazing!"

FAQs for furnace / forced air heating system install or replace projects in Guilford, CT

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.
