"Dalton drove out to the ranch outside Rapid City, SD several times to take care of the shower and the kitchen sink. My mom is 90 years old. Dalton not only fixed everything, he also was so kind and courteous to my mom. When mom mentioned the roof had a hole in it. He climbed up and took pictures. He then recommended another employee to come out and fix the roof. I could not have asked for a nicer, professional and kind person to come all the way out to the ranch to take care of my MOM. I highly recommend Loyal Plumbing Heating and Cooling for all your household needs and fixing. Thank you."

"Adam and Bo came in and evaluated my situation. Professional and courteous and gave me options to replace my furnace and air conditioner. Quality work at a price point that was less than other companies that quoted me the same equipment. When I asked Adam to help me understand why he told me that they were the owners and other companies pay employees to do the work. Highly recommend Ace for anything that has to do with your own heating and cooling needs."

"Justin was very professional and efficient. He offered me several ways to go about having my repairs done that accommodated my budget. He had the job finished in a very timely manner. He was very nice and nonjudgmental of my issues. He also fixed a few odds and ends while he was under the house and made sure my furnace was ready for this winter. I?m very happy and will have him back in the future."
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.
