"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"Within 5 minutes after Roy walked in, I knew I was speaking with an expert. He talked me out of wasting money on what I wanted (getting rid of boiler and replying on furnace) telling me about how everyone in the city during -40 degree nights was will freeze and if I keep the boiler I'll be comfy. He also talked me out of choosing a heat pump, saying in Chicago it will cause problems in the dead of winter and then I'll be out of luck. Initial estimate was only to replace the 60 year oil leaky boiler and 40 year old loud AC and furnace. Came in, did the work quickly, and when we were doing final inspection he pointed out where my last remaining original furnace was having problems. Gave me a great price to just get the the last furnace and AC done (AC was 40 years old). I know they won't be the cheapest but if you want someone you can trust who will guide you with his 30 years of experience and teach you the finer details of heating and cooling while delivering quality work, go with Porterhouse. I won't trust anyone else."

"Nothing but good things to say about American Family Heating and Cooling - highly recommended. Tim was friendly and professional on the phone, and quoted all charges up front. Nick came out and had a great combination of informal but professional demeanor. And no objection to me looking over his shoulder as he worked!"

"It went very well. We didn't know why our furnace didn't work, so Adam arrived and ran diagnostics while keeping me informed of exactly what he was doing and why. When he determined that the furnace was fine, he showed me the thermostats that he had available and then installed the one that I chose. His company also provides a furnace upkeep program that does bi-annual cleaning and diagnostics of the furnace and air conditioning units. Since he clearly knew what he was doing, we decided to sign up for their program. The approximate price below includes the cost of 1) an emergency, overtime service call 2) the replacement of the thermostat 3) the annual service program for 2 furnaces."

"Brian was the sales person and thankfully he was the first person of four to bid on our job. He took the time to explain what we really needed, why we needed it as well as what we didn't need and why we didn't need it. His professionalism, knowledge and ability to explain HVAC to someone who is not familiar with it made all of the difference. None of the other three companies met the standard he set. The real icing on the cake was that the TR Miller bid was also the most affordable.
Ben and his team came to install the system today. They were on time. They were very accommodating. They worked quickly, efficiently, remarkably quietly and effectively. Ben took the time to explain how everything was installed and why it was installed the way it was. He also explained fully how the thermostat and humidifier work.
Our house, inside and out, is cleaner and neater than when they began their work.
We couldn't be happier. I will actively recommend their service to anyone."

"On a Cold and Snowy 2nd day of Spring 2020, my heating system went out and got really cold in the house. Called Four Seasons to come out for an immediate repair. Four Seasons was able to come out within 2 hours. Technician was very knowledgeable and fixed the the problem right away and my furnace was up and running before the freezing night came. Thanks, Four Seasons!"

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