"The job went reasonably well. They completed it in a day and a half. The guys on site had a little trouble installing the high tech thermostat for the system, but their supervisor demonstrated real accountability when he showed up on a Saturday to make it right."

"Excellent service by MarKool. First it is a small company so when you call them you talk directly to the person doing the work. Second they are highly responsive. Third at the home they are very personable and answer all questions in detail. Fourth In fixing my problem they showed they are highly skilled and experienced in HVAC in this case as it pertains to gas furnace operation."

"They do a very thorough job. An itemized list of everything done is provided. They provide helpful suggestions. I am very pleased. Not every similar company works on both heat pumps and oil furnaces."

"From the beginning - Sean was extremely responsive to all of our questions and very flexible with scheduling the service. He installed our new humidifier on the furnace, provided instructions on how to operate it, and offered multiple tips for keeping the system running efficiently. He also offered a very fair price. He was very professional, and we would definitely hire him again!!"

"The technician arrived on time and was very professional and nice. He explained what was wrong (the compressor was locked up) and he wrote an estimate for a new system on the spot. I ultimately went with a different company (a slightly better price) but GAC was a very close second and I would not hesitate to consider using their services."

"During the initial service visit, the representative (Xavier) gave a detailed explanation of the condition of the HVAC system and the repair options. I hired JDL and two days later they arrived first thing in the morning to install a new system (furnace and A/C). The quality of their work and products recommended are excellent. I highly recommend their services."

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.
