"I had both my A/C and furnace serviced by Jeffrey recently, on separate visits. Jeff is a terrific young man who is *exceptionally professional and informative.* He answered all my questions and gave me sound advice on an aging system. Would 100% recommend this company to anyone who is looking for heating/AC work. Courteous office staff is also very helpful & friendly with scheduling and follow-up. I wish all my home service calls were this pleasant!"

"When called to check our aged boiler, David S. arrived that within hours. When a flow valve exploded in his hand (OUCH!), he calmly and stoically arranged for a new heating system to be installed the next day. Aaron and Nate were prompt and thoroughly professional. Aaron, in particular, took the time to answer questions and provided clear information for the new system's operation. We've always been pleased with ARSBoston's service for our A/C system; it is VERY comforting to know that they will be servicing this new gas boiler for years to come. The quick response and remedy provided by ARSBoston will never be forgotten; we are truly grateful!"

"The service couldn't have been better: quick, efficient, polite, pleasant, courteous, reasonably priced - and he got everything working again in no time. Not only that, but I had a jet-lagged son upstairs who was sleeping while Kevin was here, and he made a real effort to be as quiet as possible. I highly recommend this service!"

"Mike was quick to respond, messaging then picking up the phone (the old fashioned way). He also was the closest to me, location wise. He asked for a few photos of the water heater needing replacing. I had no luck searching an electric heater in the same size. We discussed the pros & cons of downsizing, but he was able to special order what I had wanted, with delivery the next day! He was able to adjust his schedule to install the heater shortly afterwards! After an initial glitch of my breaker switch tripping & water not heating up, I am very pleased with the outcome. I wouldn't hesitate to call him again, if the need arises & would definitely recommend him to others!"

"We wanted a back up generator that would serve us for years to come. We interviewed a number of potential installers but wanted to be sure that our electrical system was installed with integrity, safety and design. As a contractor myself I am very particular about people I hire so, that it why we chose Paul Foley and Premier Generator for our generator installation. They stand behind their product and service what they sell as well as warranty the equipment for double the manufacturer's timeframe. We have already needed our new system three times and it has been working as promised. It's electrical, hire an electrician!"

FAQs for furnace / forced air heating system install or replace projects in Dennis, MA

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.
