"NV Heating and Air Conditioning installed a Bosch heat pump in my home and removed the previous oil furnace. They did an excellent job throughout the entire process, including recommending the right heat pump for my home, providing clear guidance, assisting with the Mass Save rebate, and offering a very reasonable project cost. They were always available to answer questions, and the installation was seamless and efficiently completed. The Bosch heat pump has been running perfectly for the past two and a half months. I would highly recommend NV Heating and Air Conditioning for similar projects."

"This company has been awesome. I am a Worcester resident and have no clue about heating systems. David Clay and his team came out to look at my boiler. It was not firing. Winter is fast approaching. David provided a free estimate and also encouraged me to look at quotes from other competitors. I did. And his pricing was best aligned with my budget. His quality of work is amazing. David and his technicians fielded all my questions- I had many. Their customer service is amazing as they had all the patience and courtesy to educate me about the work and boiler systems. My experience as a customer is that Clay Plumbing Heating offers the best quality, professional craftsmanship, best client service, and at the best rates."

"SumZero Energy Systems have been excellent in the last several months with supporting the replacement of my air conditioning system in my old condo as well as servicing my furnace. A price comparison with other local companies also prooved SumZero Energy Systems offered the best price. When I purchased a home a few months later, I called them to take a look at my air conditioning system and furnace because I felt as though they had provided such excellent service in the past. It was a no-brainer to ask for consultation regarding the heating and cooling systems in my new home! When I contacted them for assistance or consultation, they are usually quick to respond and provide appointment times had a very convenient window! They have shown up on time to all of the appointments I have had. David S. has always taken the time to explain everything thoroughly and answer all my questions. I highly recommend SumZero Energy Systems!"

"Derek and DG Heating and Cooling is the service company that we all hope to find, but so rarely can. With D&G I got the real deal -- a company that knows their trade and gets the job done quickly and at a fair price. What a pleasure to NOT get the hard sell at an inflated price, pitched by a hired marketer with little knowledge (which is exactly what I got at two of the other, also highly-rated, AC service companies in the area)!"

"Al and Jamie were flexible, fair and diligent in their work. They clearly explained the choices that we could make for a whole home heat pump system and why they recommended a particular approach over others. Overall we're very happy with the system and the service that we received."
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.
