"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 have been in our home for a little over a year and thought it best to have our furnace serviced especially since we don't have a detailed history of service. Frankie D showed up 5 minutes early for our appointment which was fantastic. Frankie was quick, clean and gave me a once over on the age and condition of our furnace. We talked about when the next service would be due. I couldn't have asked for a better experience and I am thankful that we now have our go to company for anything furnace related."

"We have a heating service contract with Sila and had our annual scheduled service call on 2/26/19. We've always had excellent experiences with the staff who have serviced our furnace, and today was no exception. The technician, Guy, came promptly and very efficiently performed the required testing and measurements of the service procedure. Before he left, I asked for some information about future replacement of the burner and possible changes to our heating zone arrangement. He gave a very clear explanation of what to consider about making any future changes, what might potentially be involved, and answered all of our questions knowledgeably. Thanks to him we can proceed with our decision process with better understanding."

"I called on Saturday for an emergency visit because my furnace stopped working. Adam was very responsive and scheduled a visit in 2 hours. The technician Jeff arrived on time and was professional and knowledgeable. He quickly diagnosed the system and fixed the problem. He even left me a fuse just in case the board gets overloaded again in the middle of the night. The emergency rate was reasonable. Overall a great experience. Would definitely use them again!"

"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."

"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."

"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!"

"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)!"

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