"The gentleman from Kingdom surpassed every other furnace service that we have EVER had. He called within 10 minutes of our request on home advisor promised to be here within an hour and he arrived 45 minutes later. He diagnosed the problem with our furnace went to the store and returned with a new pressure release valve within a half hour. Installed it tested it, bled the lines which immediately improved the heat in a cold bedroom. I can't say enough about how totally excellent this repair man was if I could give 10 stars I would."

"Matthew responded very quickly to my call and showed up promptly thereafter. He was very professional and worked diligently to get my boiler working again and the heat restored to my home. He was able to diagnose the problem rather quickly and fixed the issue, even going so far as to explain many of the parts he had to replace and made me feel very comfortable that my unit was running efficiently when it was all done. I would highly recommend NexGen Aire and plan to call Matthew again for future issues. Fast, efficient, and affordable."

"I have a Navien Combi system installed in my house. To be perfectly frank it's not what I would have installed now knowing a bit more about them but Kevin was willing to familiarize himself with the system and research a bit about the furnace. I've called a large number of HVAC companies and individuals and the resounding response I received was "we don't work on those" and the click sound of being hung up on. Kevin was willing to work with my schedule and was perfectly on time for a morning appointment which allowed me to finish off the rest of the things I had to do. A huge plus! It's been a home advisor win for this home owner."

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.
