Fast, Reliable Heating & Furnace Across Near South Side
Most furnace calls we get from Near South Side come from two kinds of buildings: pre-1920s greystones with century-old steam infrastructure, or 1970s-converted two-flats where somebody ran ductwork through a chase never meant to carry it. Both break down differently, and both need a crew that has worked inside them before. We’re Fireside Heating & Air Co. of Chicago, and we’ve been driving to Near South Side since 2018. From Prairie Avenue to the lakefront corridor, we usually arrive within the hour for no-heat emergencies. Call (833) 983-1671 and a live person will answer, even at 2 a.m.
Why Fireside Heating & Air Co. of Chicago Is Near South Side’s Preferred Heating & Furnace Company
Forty-two years in Chicago means we’ve watched Near South Side transform from a warehouse district to the mixed-income, lake-adjacent neighborhood it is today. We’ve serviced the original cast-iron boilers in the greystones, the rushed duct retrofits in the two-flats, and the first-generation high-efficiency furnaces in the post-2000 infill. That history matters when your system fails at twenty below.
Our customers here are not looking for the lowest bid. They’re looking for someone who will show up, diagnose the real problem, and quote a price that doesn’t change when the invoice arrives. The 90-Day Done Right Promise covers every job: if it’s not right, we make it right, in writing, no paperwork, no arguing.
Phones are answered by a live person 24 hours a day, 7 days a week, including holidays. Nights, weekends, polar vortexes. No voicemail tree. A real human being who can dispatch a background-checked, uniformed technician to your door.
Most jobs are completed in a single visit. We carry parts for Carrier, Trane, Lennox, and Goodman on our trucks, which matters when your furnace quits on a Sunday night and the supply houses are closed.
Our Heating & Furnace Services in Near South Side
Furnace Repair in Near South Side
A typical furnace repair in Near South Side runs $150-$700. The most common calls we see are failed ignitors in aging post-2000 infill units, gas valves corroded by humid lake air, and blower motors overworked by duct systems that were never properly balanced. Winter wind chills along the lakefront corridor regularly hit -25°F, and a furnace that was limping in October will quit in January. We stock ignitors, flame sensors, and control boards for the nine major brands, and we diagnose before we quote. The price you hear is the price you pay.
Furnace Replacement in Near South Side
Furnace replacement in Near South Side typically costs $3,500-$7,500, depending on whether we’re working with existing ductwork or designing around century-old steam risers. In the pre-1920s greystones and two-flats, we often have to integrate a modern forced-air system with infrastructure that was never built for it. That takes time and skill, but it also means you don’t have to gut your walls. We recently replaced a failing 1970s forced-air furnace in a three-flat on Prairie Avenue near 24th Street. The original steam risers had been capped but left in place, so we had to snake new ductwork around them through already-tight interior chases, and install a two-zone system to fix the chronic bedroom-underheating common in these converted buildings.
Furnace Tune-Up in Near South Side
Our $89 Seasonal Tune-Up is built for Chicago’s 120°F seasonal swing. We clean burners, check heat exchangers for cracks, test gas pressure, and inspect blower components. In Near South Side’s converted two-flats, we also check whether your 1970s duct retrofit has shifted or leaked over the decades. Catching a cracked heat exchanger early beats finding out when your carbon monoxide detector goes off. Seniors and veterans always receive 5% off.
Heat Exchanger Inspection & Repair in Near South Side
A cracked heat exchanger is not a repair you defer. Carbon monoxide can leak into your living space, and symptoms are easy to mistake for winter fatigue. Heat exchanger repair in Near South Side runs $150-$700 if the crack is accessible and the unit is worth saving. If the furnace is past fifteen years and the heat exchanger has failed, we will give you straight talk about repair versus replace. No pressure. Just the facts and a written quote.

Common Heating & Furnace Problems We See in Near South Side Homes
- Chronic unbalanced airflow in converted two-flats. The 1970s duct retrofits through cramped interior chases left back bedrooms perpetually starved for heat while front rooms overheat. Balancing dampers and targeted duct remediation fix this without tearing walls out.
- Corrosion from uncapped steam pipes. Original steam boiler piping, left in place after conversion, corrodes inside walls and leaks water onto new furnace components. We see rust damage on blower housings and control boards that shortens equipment life by years.
- Undersized post-2000 infill furnaces failing in polar vortex conditions. Many mixed-income units built after CHA demolition were specced to minimum code and cannot handle Chicago’s lakefront wind chills. The furnace runs constantly, overheats, and fails on the coldest night of the year.
- Original steam boilers in pre-1920s greystones reaching end of life. Cast-iron radiators and century-old piping can outlast three generations, but the boiler itself cannot. Integrating modern equipment with existing infrastructure requires a crew that understands both systems.

FAQs - Heating & Furnace in Near South Side
Yes. We install balancing dampers and can often reroute or extend duct runs through existing chases without opening walls. In Near South Side’s converted two-flats, this is one of our most common service calls. The 1970s retrofits used minimal duct runs that starved back bedrooms, and we’ve corrected it in dozens of buildings just like yours. Call (833) 983-1671 for a free assessment.
We service both, and we’ll give you straight talk about which makes sense. Original steam systems with cast-iron radiators can be efficient and durable, but replacement parts for century-old boilers are increasingly scarce. If your boiler is failing repeatedly, we can design a forced-air or hybrid system that integrates with your existing radiators or replaces them with minimal structural disruption. Every situation is different. We do not push replacement unless it is the honest recommendation.
Usually yes, but the root cause often reveals an undersized unit stressed beyond its design. Near South Side’s lakefront exposure means wind chills regularly exceed -25°F, and many post-CHA infill furnaces were specced to minimum code. We will repair what we can, test the system under load, and tell you honestly if the unit is adequate for your space or if you are heading for repeat failure. Call (833) 983-1671 for same-day service.
Uncapped steam pipes leak water and cause corrosion, not carbon monoxide. The CO risk comes from your furnace’s heat exchanger or venting, not the old steam lines. However, those pipes are almost certainly corroding inside your walls, damaging your new equipment and potentially creating mold conditions. We can safely remove or properly cap them. If you are concerned about carbon monoxide, we will test your furnace combustion and venting as part of any service call.
In most cases, yes. We use inline balancing dampers, register adjustments, and targeted duct sealing to even out airflow without demolition. Near South Side’s 1980s retrofits are notorious for this exact problem. We have fixed it in buildings on Prairie Avenue, in the greystone blocks, and throughout the neighborhood. A free estimate will tell us whether your system is a candidate for non-invasive balancing.
