"Outstanding pricing and quick installation on a new heating and AC system. Installation of new equipment was clean and very professional looking. Justin in sales did an excellent job of listening to my concerns with the old system and proposing a new system to improve heating and cooling comfort in my home. Hvac technicians Vitaliy and Igor did a wonderful job of system installation and checkout. I could not have asked for a better experience."

"My God! Dan came out this morning, I explained what was done, he went to work on it right away! My furnace stopped working December 25th, 2024, no heat till today! Keep in mind, the last technician I hired in January 2025, charged me 240 dollars for 20 minutes analysis just to tell me I need new furnace and AC central, my AC works beautifully. Then I used 4 space heaters to keep my house warm! Man my electric bill was over 400 dollars the first month and climbing higher each coming months till Spring arrived! I hired B & D Plumbing and Heater Co. to come out and finish the job. It was a gentleman name Dan, he did an extremely awesome job, telling me the details, explaining everything I needed to knowledge. And now the furnace works about as good as it gets beautifully. The impressive part, he took his sweet time. And the most impressive part was when he presented my total bill! I was about to have a major heart attack when I saw the bill! It wasn’t through the roof bill! Cheap cheap"

"It was very reasonable and I looked around for other prices. They were very prompt and came home after working overnight shifts in the winter when my furnace wasn’t working. They helped me and replaced it within a couple of hours. I had no complains at all."

FAQs for furnace / forced air heating system install or replace projects in Big Lake, MN

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.
