"We had Fontana Bros. replace our complete HVAC system. They were professional, reliable and easy to work with. They coordinated flawlessly with our condominium association. Our HOA required that a crane be used to place the compressor unit on the rooftop and Fontana Bros. handled all the details skillfully. The technicians were extremely polite, professional, competent and knowledgeable. We are very happy with their services and recommend them without reservation."

"Thank you to Tom, Nick, and Juan. A/C needed a motor. The first part they ordered came in wrong. They found a part in Safe Harbor, drove there, drove to my house and installed it. The house had been 90 degrees. They got it back down to 75. Thank you with all my heart. You guys are truly the BEST! Christine W."

"I couldn?t be happier with my experience with Three Guys AC! They recently repaired my heat pump, and the whole process was smooth, professional, and stress-free. The technician was extremely knowledgeable, showed up on time, and took the time to explain everything to me clearly. My system is running perfectly now, and the quality of their work really shows. It?s rare to find a company that combines honesty, skill, and great customer service the way they do. I?ll definitely be using Three Guys AC for all my future HVAC needs ? highly recommend!"

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.
