"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."

"I recently had G&C Plumbing & Heating out for my gas furnace that wasn?t working properly. The furnace was due for replacing, they provided me with multiple options with straight-forward pricing. They explained each option with great detail, and we proceeded with the new install. Everything went as smoothly as possible! I absolutely recommend G&C Plumbing & Heating for any HVAC and plumbing needs!"

"David and his crew were more than amazing if I could give them 10 stars I would. David came took pictures and measurements and got the furnace that day they came 3 days early so I could have heat. They were on time very friendly and knowledgeable about what they were doing. Start to finish they were done in 4 hours. They cleaned up any mess they made and removed the old furnace I can’t say enough good about David and his crew like I said 10 Stars ⭐️"

"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!"

"Really terrific work and attention to detail. Derek and his crew are obviously super knowledgeable and professional and did not in any way try to oversell or up-sell us (Derek even told me how to clean the condenser unit in the springtime myself). The install (of a combined propane furnace and central A/C) took place just days after I first spoke with Derek, and involved minimal downtime while the old system was swapped out for the new one. I would recommend DG without reservation to friends and family (and strangers)!"

"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.
