"Home Comfort Systems was professional, honest and fairly priced. Steve Bilica (owner) came out to give me an estimate on a new furnace. He made me feel comfortable, which is important to me as a single woman. His estimate was the lowest of three I obtained ($4150) and he was so honest, he advised that my current unit didn’t need replacing yet. (The only reason I was getting estimates was because some other cut-throat company told me I needed a new one...for $11k!!...due to a cracked heat exchanger. However, all the other companies I contacted for estimates said I did NOT have a cracked heat exchanger.) I decided not to get a new furnace in the end. It’s been running great, although I did need a new blower motor about five months after the estimate, so Jeff D installed it for me ($385). Way cheaper than a whole new unit, so I’m happy. I’ll definitely go with this company again for repairs and when it’s time for a new furnace."

"Shavitz Heating and AC is a great, dependable company. I was lucky to have Rich Davis to service my furnace today for the second time. I was happy to see his face when I opened the door, as he is friendly, polite and fun to talk to and really knows everything there is to know about the work he does. It's always a pleasure to work with him. I was lucky to get him twice and I hope he'll be back in July for my next furnace check! HE IS THE BEST!"

"I purchased a new furnace and air conditioner from All Temp this past summer. They exceeded my expectations. Their quote was very competitive and we liked the Bryant equipment. The job was scheduled within a couple of days. Danny and Cody were prompt and courteous, wore appropriate PPE and left our furnace room spotless when finished. Great Job All Temp and Thank You!"

"Furnace went out in middle of the night. Primary reason I called TR Miller was pricing - over the summer a friend of mine had mentioned that she and another neighbor had their A/C and/or furnace replaced and that TR Miller's pricing was better than others.
I called TR Miller at 8am and had technician here by 11.  Larry was friendly and professional. He said I needed  a new ignitor and I asked him to clean the furnace as well - he appeared to do a very thorough job of cleaning the furnace.  He never tried to push buying a new furnace despite the age of my current one. In my experience with previous companies it seems they ALWAYS try to push you into buying a new furnace even if  your problem is a minor one, so I appreciated not having to deal with the sales pitch for a replacement furnace.   Larry even answered my questions and concerns about my humidifier.  TR Miller will be the first and only company I call next time!

FAQs for furnace / forced air heating system install or replace projects in Naperville, IL

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.
