"Shawn performed the annual heating inspection for our furnace/oil tank. As always he was very quick, and took extra time to walk me through the piping of our different heating zone. Highly recommend Genove Oil, they are providing stellar service and with employees like Shawn you are in very good hands."

"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 found Chambers Heating and AC thru Angie's list and Stephen reached out to me the same day. We set up an appointment and Kevin came out the very next day. Kevin showed up on time and fixed our issues right away. He was kind and professional. He also gave me some tips to keep my system in tip-top shape. The price was very fair and they have gained my business. I will hire them again for future repairs and maintenance."

"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"Our daughter and her husband are living out of the country, temporarily. When their leasees said the furnace was blowing cold air, we wanted the repair done quickly and at a good price. Unique Indoor Comfort Heating & Cooling responded right away and came to the property the same day we called. Very professional!"

"I would highly recommend Druziako HVAC Co. to anyone needing repairs and or replacement for Heating and cooling service. We lost our furnace Heating in the middle of the cold snap, these guys came out and immediately found the replacement system we needed and promptly replaced the next business day. Job completed, who does that..? The owner even called us during the night and offered to bring us a temp heat source if we needed it. Fortunately we did not. We can't say enough about the service. I would use them again and plan to for future cleaning and service. Nick ( the Owner i guess) and his guys did a great and professional job. Thank You Nick...!"

"We've used Atlantic Heating and Air Conditioning for over 10 years for regular air conditioning maintenance/service and repairs. They also do service/repairs for our heating system. Recently, they provided valuable advice that allowed us to fix a thermostat malfunction on our own, saving us cost of a visit. We've always been satisfied with this company - visits were easy to schedule, staff were knowledgeable, work performed was well done."

"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)!"

"Five Star Service! Total Comfort Mechanical planned, designed, and installed a Mitsubishi Intelli-Heat system at our home in Melrose. They seamlessly combined our existing gas furnace and ducted system with an efficient Mitsubishi heat pump to create a hybrid heating and AC system. The team exceeded our expectations. They are honest, respectful, and always maintained a positive and professional attitude. They did everything they said they would do and even went above and beyond. The technicians are skilled and dedicated, often working long hours to ensure the job was done right. We were impressed by their commitment to keeping our work sites clean at the end of each day. The planning was meticulous, the communication was excellent, and the final delivery exceeded our expectations. We can confidently recommend Total Comfort Mechanical for any heating and air conditioning projects. Thank you, Wendell and team, for making our home more comfortable and efficient!"

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