We’re familiar with the post-war ranch homes that line Markham’s streets, and we know the heating problems that come with them.

Markham sits on the flat Calumet plain twenty-five miles south of downtown Chicago, exposed to northwest wind corridors that drive hard heating loads all winter. The modest 1950s-1960s ranches and Cape Cods that make up most of the residential stock here were built during Cook County’s post-war southward expansion, and many still run on aging forced-air systems that were converted from gravity furnaces decades ago. That matters when your technician arrives. We’ve spent over 42 years working in homes like these. We know the ductwork was never properly resized. We know the utility spaces are often uninsulated. And we know that a straight equipment swap without checking that 1960s sheet-metal patchwork usually leaves you with the same cold spots you had before.
Why Fireside Heating & Air Co. of Chicago Is Markham’s Preferred Heating & Furnace Company
Homeowners in Markham call us because we’ve been serving this south-suburban corridor since 2018. That’s over four decades of walking into basements on 163rd Street, on Homan Avenue, in the neighborhoods near the Markham Metra station, and finding the same patterns: furnaces pushed past their service life, gravity-to-forced-air conversions that were done quick and cheap, and ductwork that leaks into the walls.
Our reviews from Markham customers mention the same things. They mention that we show up when we say we will. They mention that our technicians put on shoe covers without being asked. They mention that the price quoted was the price paid. We don’t chase the lowest-bid crowd. We chase the homeowner who wants it done right and never thought about again.
Response time to Markham is typically under two hours for no-heat emergencies. We’re coming up from our Chicago base, but we know the routes - I-57 to 167th, Halsted to Homan, the back way through Posen when the main roads are jammed. You won’t get a voicemail tree when you call. A live person answers, every time, including holidays.
Our Heating & Furnace Services in Markham
Furnace Repair
Furnace repair in Markham often means dealing with systems that should have been replaced years ago. We see a lot of Goodman and Carrier units limping along past twenty years, especially in the ranches near the Harvey border. A typical repair runs $150-$700 depending on the part - ignitor, gas valve, blower motor, control board. But we’re straight with you: if the heat exchanger is cracked, we won’t patch it. We’ll show you why, explain the safety issue, and give you a replacement quote with no pressure. Our $50 off any repair over $250 applies here, and seniors and veterans always get 5% off.
Furnace Replacement
This is where Markham’s housing stock makes us different from every other HVAC company. Most of the ranches here had gravity warm-air furnaces originally. In the 1960s, someone converted them to forced-air - usually without resizing the ducts. The supply runs are undersized. The trunk is too small. The sheet-metal transitions leak like a sieve. We’ve walked into homes where a homeowner paid for a new furnace and still had a cold back bedroom. The new unit was fine. The ductwork was the problem.
On a freezing January morning, we responded to a no-heat call on 163rd Street in Markham. The homeowner’s 25-year-old Goodman furnace had a cracked heat exchanger, but our inspection also revealed that the original 1960s gravity-to-forced-air duct conversion had undersized supply runs. We replaced the furnace with a properly sized Carrier unit and sealed the ductwork, solving both the safety hazard and the persistent cold-spot complaints.
That’s our approach on every replacement in Markham. We evaluate the ductwork. We measure airflow. We don’t sell you a box and leave. A proper replacement with duct modifications typically runs higher than a straight swap, but it’s the only way to actually fix your comfort problem. We quote everything upfront. The price you hear is the price you pay.
Furnace Tune-Up
Our $89 seasonal tune-up is built for Markham’s aging systems. We check the heat exchanger for cracks - critical in these old units. We test the gas pressure, clean the burners, check the flue draft, and inspect the duct transitions that were cobbled together in the conversion era. For a 1950s ranch with original infrastructure, this isn’t optional maintenance. It’s how you catch the problem before the January emergency call. Tune-ups run $80-$200 depending on what we find and what needs adjustment.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are the most serious safety issue we find in Markham. The combination of decades-old gravity-to-forced-air conversions, uninsulated utility spaces, and deferred maintenance means these units have cycled on and off thousands of times more than they were designed for. A cracked exchanger leaks carbon monoxide into your living space. We won’t run a unit with a cracked exchanger, and we won’t let you talk us into it. If it’s cracked, we shut it down and we explain your options. Replacement of the heat exchanger alone is sometimes possible, but on a unit past fifteen years, full furnace replacement is usually the smarter money.

Trusted Brands We Service in Markham
We carry parts and stock equipment for Carrier, Trane, Lennox, and Goodman - the four brands we see most often in Markham’s older housing stock. Goodman units are common here because they were the budget option when these homes got their first replacements in the 1990s and 2000s. Carrier and Trane show up in homes where the owner invested more. We don’t push one brand over another. We size the equipment to your ductwork and your heating load, which in Markham’s poorly sealed ranches is often higher than the square footage suggests. Our warehouse keeps common ignitors, gas valves, and blower motors on hand, so most Markham repairs don’t wait on parts.
Common Heating & Furnace Problems We See in Markham Homes
- Cracked heat exchangers in 20-plus-year-old furnaces. The constant cycling in Markham’s uninsulated utility spaces and crawlspaces fatigues the metal. We find this on emergency no-heat calls every winter, and it’s a full stop - the furnace doesn’t run again until it’s fixed or replaced.
- Uneven heating from undersized, leaky ductwork. The 1960s gravity-to-forced-air conversions left supply runs that can’t move enough air. Your back bedroom is cold because the duct is too small, not because the furnace is weak. A new furnace won’t fix this without duct modifications.
- Emergency failures from deferred maintenance. Markham’s economically strained homeowners often run systems years past service life. We get the 2 a.m. no-heat call when the blower motor finally seizes or the control board gives out. The $89 tune-up would have caught it.
- Ignitor and gas valve failures in aging Goodman and Carrier units. These are straightforward repairs, but in Markham’s tight utility spaces and low crawlspaces, access is harder than in a newer home. Our technicians are trained for tight clearances and carry the parts.

FAQs - Heating & Furnace in Markham
Because the new furnace is rarely the problem - the 1960s gravity-to-forced-air duct conversion is. The original supply runs were sized for gravity airflow, not forced-air pressure. When a contractor swaps the furnace without checking duct capacity, the new blower can’t push enough air through undersized pipes. We measure airflow and resize or seal ductwork before we call the job done. Call (833) 983-1671 for a free estimate - we’ll evaluate the whole system, not just the box.
Yes, Markham requires a permit for furnace replacement, and the work must pass inspection. We pull the permit, handle the paperwork, and coordinate the inspector. You don’t chase the village office - we do. The permit cost is included in our upfront quote. Call (833) 983-1671 and we’ll walk you through Markham’s specific requirements.
Carrier and Trane offer the best blower flexibility for undersized ductwork, and Goodman is a solid value if the ducts are in decent shape. We don’t sell you a brand. We size the equipment to your actual heating load and duct capacity, which in Markham’s leaky ranches is often 20% higher than standard calculations suggest. Call (833) 983-1671 for a proper Manual J load calculation.
Look for rust around the flue collar, soot streaks near the burners, or a persistent headache when the heat runs - these can signal a cracked heat exchanger leaking carbon monoxide. But most problems aren’t visible to a homeowner. Our $89 tune-up includes a heat exchanger inspection with a camera scope and combustion analysis. If it’s not safe, we shut it down and show you why. Call (833) 983-1671 to schedule.
Yes. Many Markham ranches have furnaces shoehorned into low crawlspaces or uninsulated utility closets that were never meant to hold forced-air equipment. Our technicians are trained for tight clearances and carry portable equipment for spaces with limited headroom. If the unit can’t be safely serviced or replaced in place, we’ll tell you upfront and discuss relocation options. Call (833) 983-1671 - we’ll come look and give you straight talk.
