We’ve been driving to Lincoln Square since 2018, when Terry Kowalski founded Fireside Heating & Air Co. right here in Chicago. The 60625 zip is familiar territory for our trucks. We know the difference between a 1910s two-flat on Lincoln Avenue and a 1930s courtyard building on Winona, and we know that “no heat upstairs” in October means something very specific in this neighborhood. Our Heating & Furnace team answers the phone live, 24 hours a day, including those 2 a.m. calls when the boiler quits on the coldest night of the year. We’ll be there when we say.
Why Fireside Heating & Air Co. of Chicago Is Lincoln Square’s Preferred Heating & Furnace Company
Forty-two years in Chicago builds a certain kind of reputation. Lincoln Square homeowners call us because their neighbor called us, or their building manager, or the owner of the three-flat next door. They remember the last contractor who quoted low and disappeared, and they want a company that puts the price in writing and stands behind it.
Our phones are answered by a live person, every hour of every day. No voicemail tree, no “press 1 for service.” When your steam boiler quits on a Sunday night in January, you get a human being who dispatches a background-checked, uniformed technician trained as a journeyman. They put on shoe covers without being asked. They treat your home the way they would their own mother’s.
Most Lincoln Square jobs are completed in a single visit. We carry parts for Carrier, Trane, Lennox, and Goodman on our trucks, and we’re trained on all nine major brands. The 90-Day Done Right Promise covers every job in writing: if it’s not right, we make it right, no paperwork, no arguing.
Our Heating & Furnace Services in Lincoln Square
Furnace Repair in Lincoln Square
Furnace repair in Lincoln Square runs $150-$700 depending on the part and the accessibility. But here’s the reality of this neighborhood: many buildings don’t have furnaces at all. They have steam boilers, hot-water boilers, or gravity systems from the 1920s. When a Lincoln Square resident calls saying “my furnace is broken,” we know to ask the right questions. Is it one-pipe steam with cast-iron radiators? A two-pipe system with zone valves? The diagnostic path is completely different from a suburban forced-air setup. Our technicians are fluent in both.
When it is a true furnace - maybe a later retrofit in a converted attic or a newer construction exception - we repair ignitors, gas valves, blower motors, and heat exchangers. We stock common parts for fast turnaround.

Furnace Replacement in Lincoln Square
Replacing a furnace in Lincoln Square is rarely straightforward. The dominant housing stock - brick two-flats and three-flats built 1910-1940 - was designed for steam or hot water, not forced air. There are no duct chases in solid masonry walls. We’ve seen too many homeowners get halfway into a ducted furnace retrofit before realizing the cost and structural impact are prohibitive.
That’s why furnace replacement in Lincoln Square increasingly means ductless mini-split systems. We install high-efficiency heat pumps that heat and cool without tearing open brick walls. For the rare building that can accommodate ductwork, we size and install furnaces from Carrier, Trane, and Goodman with proper load calculations that account for Lake Michigan’s latent moisture.

Furnace Tune-Up in Lincoln Square
Our $89 seasonal tune-up is the best investment a Lincoln Square building owner can make in September. For steam systems, we check boiler pressure, test safety controls, inspect condensate returns, and replace air vents before they fail. For forced-air furnaces, we clean burners, check heat exchangers for cracks, and verify gas pressure. A tune-up catches the problems that turn into 2 a.m. emergency calls.
Senior and veteran customers receive 5% off, always. No expiration, no paperwork.

Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we do not minimize. In any forced-air furnace, a compromised heat exchanger can leak carbon monoxide into living spaces. We inspect with visual methods and combustion analysis. If replacement is needed, we give straight talk about repair versus replace. Sometimes a new furnace is the smarter money. We’ll tell you which.

Common Heating & Furnace Problems We See in Lincoln Square Homes
- Air-locked one-pipe steam radiators after summer idle. We recently responded to a “cold upstairs” call on a 1920s courtyard six-flat on Winona Avenue. The tenant had a one-piece radiator that wouldn’t heat after the summer shutdown - classic air lock. We bled the system, replaced a sticky air vent, and had the steam flowing within an hour. Three days later we were back to install a ductless mini-split system in the same unit because the owner wanted modern cooling without tearing open the brick walls.
- Pinhole leaks in century-old cast-iron pipes. Decades of thermal cycling in 1910s-1940s buildings corrode pipe walls from the inside. These leaks often hide in inaccessible chases between floors. We assess whether strategic patching or selective repiping is the better spend.
- Failed boiler-to-furnace conversion attempts. Homeowners sometimes inherit a previous owner’s half-finished ductwork project. We evaluate what’s salvageable and what’s not. Usually, the ductless route saves money and preserves plaster.
- October cold-snap surge failures. One-pipe steam systems in Lincoln Square’s prewar two-flats produce a predictable “no heat upstairs” surge every October after sitting idle all summer - due to air-locked or water-logged upper-floor radiators - a seasonal failure pattern that technicians in newer suburban markets never encounter.

| Furnace Tune-Up | $80-$200 |
What moves a job toward the higher end? Accessibility matters in Lincoln Square’s older buildings. A boiler in a cramped basement under a 1920s three-flat takes longer to service than a utility room installation. Parts availability for obsolete steam components can add cost. And the structural realities of brick masonry - no duct chases, limited electrical capacity - mean that “simple” furnace replacements often become mini-split conversions.
We quote upfront. The price we say is the price you pay. No fine print, no add-ons after we start. Call (833) 983-1671 for a free estimate. We also offer $50 off any repair over $250, and a free second opinion on any written estimate you’ve received.

FAQs - Heating & Furnace in Lincoln Square
Usually yes. Upper-floor radiators that won’t heat after summer idle are typically air-locked or have failed air vents - a 30-minute bleed and vent replacement in most cases. We stock the right vents for prewar radiators. Call (833) 983-1671 for an exact quote; estimates are free.
Almost certainly not. Solid brick construction with no existing duct chases makes forced-air retrofits structurally prohibitive in most Lincoln Square buildings. We nearly always recommend ductless mini-split heat pumps instead. Same heating and cooling, no demolition. Call for a free assessment.
Patch if the leaks are isolated and accessible; repipe if corrosion is systemic or pipes run inside walls. We inspect with cameras when needed and give straight talk about which path saves money long-term. Call (833) 983-1671 for a free second opinion on any estimate you’ve received.
We install and service Carrier, Trane, Lennox, Goodman, and five other major brands. For Lincoln Square’s older housing, we often specify ductless systems from these same manufacturers rather than traditional furnaces. The brand matters less than proper sizing for your building’s envelope and Lake Michigan moisture loads.
Yes. Our phones are answered live 24/7, including the October surge when one-pipe steam systems wake up from summer sleep. We prioritize no-heat calls and carry the vents, fittings, and controls that Lincoln Square’s prewar systems need. Call (833) 983-1671 anytime; we’ll be there when we say.
