"I've been a customer of AC Denco for about five or six years now. Always very satisfied with their service and work. My HVAC unit was old, not large enough to heat/cool the house, not very efficient and frequently needed repair, although it was getting harder & harder for Dennis to find parts for such an old unit. Last summer, while here trying to fix my old unit, Dennis, convinced me that it was time for me to get a new HVAC unit, So, I bit the bullet, and got a new, larger, much more efficient unit. He had told me that if I had a better unit, I would see a nice drop in my electric bills, because the unit would be working much more efficiently. Well, for a year now, I've been absolutely thrilled with the new unit, and I'm loving those lower electric bills! They've been cut down, sometimes as much as 50% from what they used to be. It's wonderful. So, if anyone is 'on the fence' about whether to spring for a new unit or not....DO IT. It makes a huge difference! The house is heated & cooled Much more efficiently, we're using less electricity, and we're loving the lower electric bills! And the $$ we're saving on our electric bills, means that the unit is pretty much paying for itself! Thanks so much, Dennis and the crew at AC Denco... I really appreciate all of you!!"

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

"Great experience. Responded quick and had my ac up and running. Also, informed me on how to tale care of my system. Will use them again for future maintenance."
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.
