"Gil, RAF and Luis installed a new Lenox furnace/AC in my condo yesterday. They were here on time, worked quickly and were done earlier than I expected. All my interactions with them were informative and friendly and at the conclusion of the installation they took the time to show me, and explain to me what they had done. The new thermostat is a bit of a challenge, but they got me started in the setup process so that I could complete it. Before they left they thoroughly cleaned the areas they had worked in and traveled through. You will be very fortunate if you get this crew to install your new furnace."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"It went very well! Dylan was knowledgeable about removing our old oil burner that had died, and installing the new heat pump unit! The work was done in a timely fashion and he removed the old heater and cleaned up everything from the new install. He also followed up after a few days to make sure everything was okay, which it was. I would recommend Venture Mechanical to anyone of my friends, and will use them in the future for routine servicing on the system and for any other HVAC needs I may have!"

"Service guy was very thorough and explained everything he did. Also what he would recommend to be done come spring. Like the idea of a service plan they offer coming twice a year to check heat pump. Would totally recommend them to others having heat pumps."

"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."

"Good communication and quick service during a heatwave"
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.
