⭐⭐⭐⭐⭐ Rated 4.9/5 | 300+ Five-Star Reviews | Buffalo Grove’s Trusted Heating Team

“Our builder-grade furnace lasted 22 years but was on its last legs. Midwest Comfort came out, measured the house, showed us three options with real numbers, and installed the new system the following week. Professional from start to finish.” — Verified Buffalo Grove Customer

Buffalo Grove Furnace Replacement Triggers

Buffalo Grove’s planned communities, built primarily from the late 1970s through the early 2000s, are entering the lifecycle window where original and second-generation furnaces require serious evaluation. We recommend replacement conversations when:

  • System age exceeds 18 years: While some furnaces last beyond 20 years, the probability of major component failure increases sharply past 18 years, and efficiency has typically degraded by 10 to 15 percent from the original rating.
  • Heat exchanger integrity is in question: A suspect heat exchanger is the most serious replacement trigger. Repair is rarely practical, and the safety implications of a cracked exchanger—such as carbon monoxide exposure—are too significant to manage with monitoring alone.
  • The furnace cannot maintain temperature during extreme cold: If your home drops below the thermostat set point during sustained single-digit temperatures, the furnace is likely undersized for the current load or has lost enough capacity to meaningful underperformance.
  • Parts sourcing is becoming difficult: When a repair requires a special-order part with a multi-week lead time, the system has reached the obsolescence threshold. A new furnace eliminates supply chain risk entirely.

Frequently Asked Questions — Furnace Installation in Buffalo Grove, IL

The most efficient residential gas furnaces on the market operate at 98 percent AFUE, meaning only 2 percent of the gas consumed is lost as waste heat. Whether this tier is the best value for your situation depends on your gas consumption, the rebates you qualify for, and how long you plan to stay in the home. We run the numbers with you during the estimate.
Yes. The main modification is converting from metal flue venting to PVC intake and exhaust pipes, and adding a condensate drain connection. We handle both as part of the standard installation. Most basement installations are completed in one day.
Our crews aim to minimize disruption. We use drop cloths, shoe covers, and clean up all debris. The furnace room and immediate surrounding area will be a work zone for the day. In most cases, you can continue normal activities in the rest of the house.
There will be a period without heat during the swap—typically four to six hours. We schedule installations to complete the full changeover within a single day, so you have heat by evening.
Square footage alone does not determine the right size. Insulation, window area, ceiling height, and air leakage all factor in. A 2,500-square-foot home might need anywhere from 80,000 to 120,000 BTU depending on these variables. Our Manual J calculation determines the exact answer.
Yes. We guarantee our workmanship in addition to the manufacturer’s parts warranty. If an installation-related issue occurs, we return and resolve it at no charge. Our goal is a system that runs perfectly for its entire lifespan.

Excellent service. Very good knowledge about heating and cooling system. Nice experience with the technician.
The owner of Midwest Comfort Heating & Cooling LLC based in Elk Grove Village, IL recently assessed the heating and cooling issues in a relatively new-to-me home. The estimate process for the work needed was straightforward and reasonable. I am confident I made the right choice in having Mark - the owner, plus Leo install a new furnace and a new air conditioner. they were professional, courteous, and arrived when they said they would. I am glad I chose a locally owned company with great customer service!

Sooooo.....we were just returning from an exhausting (but fun) vacation. The weatherman said the temperature would be in triple digits. I turned on the air conditioning. A couple hours later, our home was still hot and I realized the A/C wasn’t working. Panic! Quick! I called Midwest Comfort Heating and Cooling and spoke with Brian. He set up an appointment for the same day. The same day! Mark came out and immediately found the problem. He was professional, knowledgeable and explained everything. Viola! He had our system was up and running in a very short time! I can’t say enough good things about Midwest Comfort Heating and Cooling. I certainly give them the “mostest” number of stars. I don’t do a lot of reviews and/or “give stars,” but I certainly need to let people know how happy I am with this experience. I certainly will use them in the future for maintenance in our home and hopefully won’t need them a lot for emergencies like this but happy to know they’re there when needed! Thank you, thank you. I truly highly recommend Midwest Comfort Heating and Cooling!

When our 60 year old boiler stopped working on the coldest day of the year, which happened to be a Saturday, we called a number of furnace repair places who either didn't answer or couldn't come out for several days. Midwest took the call and was at our house within 2 hours. During that time, they kept us updated on their ETA. The repairman was courteous and professional. He fixed the problem quickly and we had heat a short time later. The price was very fair considering the circumstances. I highly recommend them.

1/6/26 - last month I finally had to bite the bullet & get a new furnace and A/c. They were honest & Fair. I got the smaller unit per Leo’s suggestion. They were fast, efficient and thorough. They were even able to fit a humidifier in a very tight space where previous companies said would never fit. I love having a humidifier in the winter. My Google Nest thermostat was malfunctioning a few weeks later and Leo just came out and got that working. I’m very happy to be in their Comfort Club. This is a small company so you get to know them, and they treat you well. 2024- Today I had a motor replaced by Leo and once again the service was great and I renewed my service plan agreement. 2023- Jeff replaced two parts in the furnace, and informed me that the filters I was using were restricting the airflow too much. He also informed me that the unit I bought 15 years ago from a different company is too big for my house so he adjust the gas burners so I don’t over heat my unit. He was VERY good and carefully explained everything. Thank you Jeff!

Midwest is now my HVAC company of choice. Leo has been here 3 times. Super friendly and explains things very well. I particularly like the fact that you're not one of those companies that are Jack of all trades, like HVAC, electric, plumbing, but masters of none. (Looking at you, 4 Seasons!) I had yearly maintenance. The price was competitive and fair. See you again in the spring for the a/c, Leo!

I’ve used Midwest Comfort for years on my own home. Always professional and honest. Recently reached out to have my mother’s home maintained/serviced. Mark was excellent, on time and professional. Cleaned her furnace and diagnosed any issues as the system is nearing replacement. Mark was honest with her and went through options should she decide to replace the system. Could not be happier with the service. Will definitely be recommending Midwest Comfort to family and friends. One of the few remaining independent HVAC businesses you can trust.
