"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."

"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!"

"We have central heat, it's like a boiler, and they inspected it and they found that the hot water cut-off part, which is a significant part for operating it safely, was not in good condition. He ordered the part for us, and got it rather quickly, that same week. We like them. They have a provider there, that maintains our type of furnace, which is a Peerless. We like this man, because he knows what our furnace should be like. We've only been dealing with them for, it was last season and the one before. Our previous man had retired and was no longer available. Both times they sent somebody who clearly knows what our furnace should be like, ans when it's operating right."

"Our AC unit had stopped working the previous day, so I called a few local companies in the morning.
The only one that answered without going through voicemail was Jon (the owner) at JML.
After explaining our problem he had a few ideas of the cause, so we scheduled a service call for the same day.  He called when he was on his way and arrived on time.
Once here, he checked over the unit and diagnosed the problem.  Fixed everything while he was here and kept the price to the service charge.
Jon also gave some advice on a separate issue with the location and sizing of our return air ducts that would make the system more efficient.

FAQs for furnace / forced air heating system install or replace projects in Northbrook, 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.
