"I've used this company for a few years, beginning with an issue I had where I needed some emergency assistance with an a/c system leaking water into the house. They fixed the issue and it cost far less than I thought it would. I've also used them for a couple heating repairs, annual furnace cleaning and a/c maintenance. I am about to hire them again since the a/c system is dying and it will need replacement since it's more than 20 years old. I would highly recommend Unique Indoor Comfort to anyone in need of a good HVAC/Heating company."

"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...!"

"Excellent. I've had Genove install both gas and oil heating systems in my properties, most recently oil. They have also installed central air/hydro air and handle my oil delivery. The techs have always been polite & knowledgable. Their customer service is impeccable. As a landlord/home owner, I couldn't be happier with them handling all my HVAC needs and would recommend them to anyone."

"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!"

"We've used Atlantic Heating & AC for many years and wouldn't consider any other company. Atlantic is extremely responsive, priced reasonably, and they always do a great job. We've never once had to call them back to resolve any issues associated with their work, and they've done a lot of work over for us over the last 9 years. Recently, our water heater died very suddenly; I came home from my office and water was leaking out of the water heater onto the basement floor. Within minutes, their service manager was guiding me over the phone regarding which valves to turn off etc. and he had me take a few pics to send to him. The very next day, a serviceman was at our house installing a brand new, much better water heater than the house had come with, and we haven't had an issue yet, and this was several months ago. I'm a Realtor and Atlantic has bailed my seller clients out of HVAC issues on a moment's notice, so I will always be grateful for the excellent sales and service that we receive thanks to Atlantic Heating and AC."

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.
