"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!"

"Getting in touch with Sean was pretty straight forward. Once we finally settled on a date, they were there and on time. I was having my entire HVAC system replaced. The furnace was a small room above my bathroom and the compressor was outside and needed a crane to access it. They were able to get all of this done in one day and so far so good. The most important part of this is his price was much lower than the other estimate I received. The other estimate was higher than what my neighbor paid and they removed the entire roof of her bathroom!!!"

"The appointment was made within 2 days of contacting them. The technician (Brian) was punctual for a 7:30 am appointment. Once there, Brian did a fantastic job of communicating the services that he was performing and kept me very informed about the status of the AC system. He found some issues that had been previously overlooked by former HVAC technicians and provided me with a very detailed understanding of what the outlook for my unit should be in the future. I noticed an immediate improvement in the cooling of the house as well as the air quality. I can't thank this company and this technician enough for being so professional in the way they conduct their business. I would recommend them to anyone in need of HVAC service."

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

"Paul found the most suitable system for our smallish cottage house, and he and Daniel were invaluable in explaining how a modern thermostat works to get the right settings. Once the purchase was made, the company quickly installed the heat pump. The company also helps with the rebate forms. During the recent cold nights, the heat pump has worked flawlessly. We are very satisfied with the product."

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