"I was able to get a same-day appointment, and Abraham showed up right on time. He took a look at the system and confirmed that the furnace was running as expected, and he didn’t find evidence of a cracked heat exchanger. I was hoping for a definitive answer as to why the air wasn’t flowing out of several of my vents, but he was only able to confirm that it wasn’t due to the furnace itself. I may have clogged or separated ductwork behind the walls, but he wasn’t able to diagnose/confirm. At least I know the furnace itself isn’t the source."

"This company was without question one of the best we have worked with. Polite, honest about the work to be done and the time frame to get it done. Our Navien boiler/heat combo went on the fritz during a major cold snap and the holidays, a double whammy. They came out that very day. Jared was our technician, he was awesome. Kelley's was able to get the needed part to fix the issue the next day. He came back not only fixed the problem, but waited for 30 minutes before departure checking the system and making certain everything was running as designed. Since the combo system went down during such extreme cold days, extra pressure built up that didn't present itself until the next day. We texted Jared, he not only responded to the text, he called us immediately, on a Sunday and walked us through what turned out to be a simple fix. Things have been running smoothly ever since. Jared was awesome. This is our families team FOREVER!"

"We finished our basement last year. At that time we upgraded our existing furnace so that we can heat both main floor and basement. Another HVAC contractor (not Bell Heating) performed this task and added two zone dampers for the two floors. After this work was complete, the main floor was always overheated. Since the original heating contractor refused to fix this problem, I contacted Bell Heating. George from Bell Heating explained that the zone damper for the main floor is stuck at open position blowing hot air all the time. The original zone damper was in a very difficult to reach position above a corridor and there were gas and drainage pipes surrounding it. George and his supervisor worked very hard to cut ductwork to extract the old zone damper and patched the hole. They ordered a new one to replace it. When the new one arrived, they placed the new zone damper in a position which can be easily accessed. This work involved repeated visits from Bell because the damper was not a size that is readily available in market. Now everything is working fine and main floor heating is again controlled by the thermostat as it should be. I am very pleased with Bell heating for fixing this problem."

"David quoted me a flat rate over the phone. When he started work, it turned out our new home's furnace had probably not been serviced for years. It was a mess of gunk clogging up nearly everything--heat exchanger, coils, radiators--the works. He did the entire job without complaint--and didn't change his already very reasonable price. Hard to beast such excellent service at such a reasonable price."

"We had 3 employees from Thurston do the work. I believe that they did a quality job for a very reasonable price. They were cordial and very willing to answer questions as they performed their job. I did have an issue with a vent after they left, but with a phone call, they promptly addressed and resolved it. I recommend them!"

"Hello, We had Cangianni Electrical Inc. install an antique Waterford chandeliier with a lift, a timer in the powder room and a smoke alarm/combination carbon monoxide. The latter was easy and installed in minutes. The chandelier was a delicate job that required patience and extreme care. Also, the chandelier was missing a vital piece which was the screw/tear that kept the bottom plate together with a smaller plate. Nick Cangianni had to create and resize a screw that would keep these two pieces together. The tears, bulbs and other smaller pieces took him half day because of the delicate pieces. Also, he had asked his brother to move the air conditioning duct away from the chandelier connection in the attic. One chandelier, five men and two and a half days. We have to give Nick and his crew credit for a wonderful and detailed work. THANKS NICK! Sincerely, Marienella and Steve N."

FAQs for furnace / forced air heating system install or replace projects in New Fairfield, 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.
