"My furnace was not working over the Memorial Day weekend and the tempurature was unseasonably cool. Select Mechanical Services found that three items needed to be replaced. Since they didn't have the parts on hand at the time, they were able to get the furnace to work for the rest of the weekend and returned four days later and fixed the furnace."

"Scott was wonderful to work with. He first tried to give me a self fix over the phone to same me a maintenance call. This did not work so I called Scott back to schedule an appointment. Scott came out the following morning and identified the issue was more complex after his own inspection. He fixed the issue and gave me some tips on self maintenance for my Heat Pump heating and cooling unit. I would highly recommend Scotti Mechanical Service and will definitely using Scott for future routine maintenance and/or other issues with my heating and cooling system."

"Highly recommended. I hired Bruce to replace my ancient heating system, and he and his crew did the job with great care, skill, and professionalism. From my first contact with him, Bruce was patient, knowledgeable, and eager to make sure all my questions and concerns were answered and addressed. He and his crew were kind, considerate, and safe. I would have no hesitation about hiring Williams & Associates again, their services are outstanding."

"After another vendor recommended major repairs to a central AC system, so I called Parker Heating and Cooling to get another quote. Although I did not ask for a diagnosis, Jeremy inspected the system and discovered an overlooked minor problem, which he took care of. His diligence and honesty saved us thousands of dollars! Jeremy was very responsive and easy to deal with and checked back to make sure the problem was resolved. These days "five stars" has diminished in meaning, but this truly was excellent service!"

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.
