"We have worked with Sila for many years. They installed 2 hot air gas furnaces at my South Boston rental property a few years ago. They have serviced 4 systems each year. Last month, they installed 2 new gas furnaces. The sales rep was great to work with and gave us a substantial credit to make the numbers work for us to install the 2 systems. The team of 7 arrived early the next day, installed each system, then an inspection by the lead tech was done after that. The job was done in one day. Everyone was and always is very professional and very good to work with. They do the job and clean up after. They provide 24 hour service which I need having a rental property. They are reliable and I can always get someone to go out to the house no matter what time it is. They always call you right back when calling after hours. The prices may seem a bit higher than other companies for emergency or any service but it's well worth it because they respond and show up. They also offer many specials for tune ups, plumbing, etc. I highly recommend Sila for any of your heating, air conditioning, and plumbing needs."

"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!"

"Lost heat on coldest day of the year so far. When we came home after being out for 3 hours or so, the temperature in the house had dropped from 70 to 61. Green Energy was able to get to our home in about 2 hours and corrected the problem quickly."

"We chose Pro Heating & Cooling to do an oil to High Efficiency gas boiler conversion. Sean provided a clear and concise quote for the the full job, including a challenging removal of our oil tank. We needed the job done ASAP and Sean was able to accommodate our request and complete the full job in a day. His crews were prompt, and seamlessly coordinated to convert our combo forced hot water and air system while creating a much tidier and well laid out integration with the new boiler and indirect water heater. After the instillation Sean checked in and came to do minor adjustments to ensure the system was dialed in to run perfectly. Lastly, the pricing was great, and the instillation was designed to maximize the available Mass Save rebates for energy efficient systems. I'd recommend Pro Heating without hesitation (as I did to a friend/neighbor)!"

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