"The process was slow initially as I had to interview several HVAC before finding 3 who were willing to do the work. One was priced much too high and I didn't like the initial proposal of the placement of lines. Another contractor didn't fill me with confidence and they are part of a company that split off with different franchises (I believe). NETR's contact person, Russell, who evaluated the project was open to the idea as well as followed up with technical advice as this was a nonconforming application. After several reviews by NETR personnel and outside engineers to make sure there was enough airflow for the compressor, where and how to run the lines inside the loft; I had my carpenter build an aluminum box which took time as it was custom-ordered of sheets to be build on premises. After it was setup, NETR took over, evaluated the box, re-reviewed the plans, and subsequently sent 2 very competent techies. The job took 3 1/2 days which was fine with me. The last day a 3rd technician replaced one who had to go over to another job. They were polite and answered any questions I had. They left the place in clean condition. The system lines looks very nicely put together, works beautifully, cools the condo very nicely (remember 23 5' high windows w/plenty of solar gain). They subcontracted an experienced electrician who's expert workmanship convinced me that I will use him for future work. Terrific company who's customer service is conscientious and with good follow-through. Their abilities and experience revealed themselves in this application and I'm very grateful that they wanted to try out this nonconforming application as the only options left to me were window ACs which I find unsatisfactory, and in the bedroom impossible to sleep with while on.

"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)!"

"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."

"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."

"Everyone I dealt with was very courteous and professional. Everything went well and the system was installed in one day. Derek came back to check the work the next day and show me how the remote control works the system. I was very satisfied with this company."
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.
