Our Heating & Furnace Services in Lower West Side
Furnace Repair in Lower West Side
Most furnace repair calls in Lower West Side involve systems that were retrofitted into buildings never designed for forced air. We’ve replaced ignitors on 30-year-old Goodman units in Pilsen basements, repaired gas valves on Rheem furnaces crammed into former coal rooms, and traced electrical faults in ductwork that was routed through plaster walls in the 1970s. A typical furnace repair in Lower West Side runs $150-$700. We stock common parts for Lennox, Goodman, Rheem, and York to complete most jobs in a single visit.

Furnace Replacement in Lower West Side
When a furnace in a Pilsen two-flat reaches the end of its life, replacement isn’t straightforward. The original building had no ductwork. Somebody, decades ago, cut channels through floors and walls. That retrofit ductwork is often undersized, poorly sealed, or routed in ways that restrict airflow. We evaluate the whole system, not just the box in the basement. Furnace replacement in Lower West Side typically costs $3,500-$7,500. We’ll tell you straight if your existing ductwork can support a modern high-efficiency unit, or if the job needs more than a swap-out.

Furnace Tune-Up in Lower West Side
Our $89 seasonal tune-up catches problems before they become 2 a.m. emergencies. In Lower West Side, we pay special attention to heat exchangers on older furnaces and to the condition of retrofit ductwork. A tune-up in this neighborhood often reveals issues a suburban tech would miss: restricted returns, blocked vents buried in renovations, or combustion air problems in tight basement mechanical rooms. Regular maintenance runs $80-$200 and extends the life of a system that’s already working harder than it was designed to.

Heat Exchanger Inspection & Replacement in Lower West Side
Cracked heat exchangers are a serious safety issue we see regularly in Lower West Side’s older forced-air retrofits. These furnaces were often installed in buildings with marginal ventilation, operated for decades with minimal maintenance, and subjected to thermal stress from cycling on and off through undersized ductwork. We inspect with visual tools and combustion analyzers. If replacement is needed, we’ll explain exactly why and show you the crack. This is not a repair to delay. Carbon monoxide risk is real, and we treat it that way.

Trusted Brands We Service in Lower West Side
We’re trained to service nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Lower West Side, we most commonly work on Goodman and Rheem units that were installed during past retrofits, and on newer Lennox and York systems where homeowners have upgraded. We stock parts locally for faster turnaround, because a January night in Pilsen is not when you want to wait on a warehouse shipment. Our journeyman technicians carry the tools and components to complete most repairs in one trip, which matters when you’re heating two or three units in a single building.
Common Heating & Furnace Problems We See in Lower West Side Homes
- Cracked heat exchangers in 50+ year old forced-air furnaces. These units were retrofitted into boiler-based buildings, often without proper duct sizing. Decades of thermal cycling in tight mechanical rooms takes a toll. We inspect thoroughly and replace when safety is at risk.
- Sediment-clogged steam boiler pipes and missing radiator air vents. Every October, Pilsen generates a wave of these calls. A season’s worth of sediment buildup, plus tenant-tampered or missing air vents, causes banging radiators and cold upper units. It’s a seasonal failure pattern tied directly to this neighborhood’s age and rental density.
- Undersized or poorly routed ductwork from past retrofits. Restricted airflow causes furnaces to short-cycle in winter and leads to uneven heating. In summer, the same restrictions can cause coil icing on air conditioning. We measure static pressure and airflow to diagnose what the original installer missed.
- Loft conversions with mis-sized heating systems. The former industrial buildings along Cermak Road and the Chicago River have oversized, high-ceiling volumes. Standard load calculations don’t apply. We’ve corrected too many installations where a contractor treated a 14-foot ceiling like an 8-foot one.

FAQs - Heating & Furnace in Lower West Side
You replace a heat exchanger when inspection reveals a crack or failure, not on a schedule. In Pilsen’s retrofitted two-flats, we find heat exchanger problems most often in furnaces that were installed 25-40 years ago, operated with restricted airflow, and never tuned. Annual inspection catches this before it becomes dangerous. Call (833) 983-1671 to schedule - estimates are free.
Yes, and in many Pilsen two-flats it’s the better approach. Your steam or hot-water system works fine for heating. For cooling, we install ductless mini-splits rather than tearing out functioning radiators to force ductwork through century-old plaster. We’ve completed many such jobs in Lower West Side buildings where preserving the original heating was a priority. Call for a free assessment of your specific layout.
Brand matters less than proper sizing and installation for lofts with 12-16 foot ceilings. We’ve installed Goodman, Rheem, and York systems in these spaces successfully. The critical step is an accurate load calculation that accounts for volume, not just square footage. A furnace that’s correctly sized for a Cermak Road loft will be a tier or two larger than standard calculators suggest. We measure twice and install once.
It’s steam hitting water that shouldn’t be in the pipe, caused by sediment buildup or a failed/missing air vent on the radiator. In Pilsen, this happens every fall because the building’s original 1920s steam system has accumulated a season of debris, and tenants or previous owners have lost or painted over air vents. It’s fixable, common to this neighborhood, and not something a suburban technician sees often. We replace vents and flush problem risers.
Yes. Many Lower West Side buildings have a forced-air furnace that heats the main unit while a steam or hot-water boiler still serves the upper flat or remains in the walls from a past partial conversion. We’re fluent in both systems. On West 18th Street in Pilsen, we serviced a 1920s two-flat where the homeowner’s forced-air furnace, retrofitted decades ago, had a cracked heat exchanger from age and the original steam risers were still in the walls. We replaced the furnace with a high-efficiency 96% model and sealed off the abandoned boiler connections, restoring even heat throughout both units. We handle the full scope, not just the part that’s easiest to reach.
