We are Fireside Heating & Air Co. of Chicago, and our Emergency & Commercial HVAC team has been serving Winnetka since 2018.

Winnetka sits on the Lake Michigan bluff, and that location shapes everything about how we work here. Lakefront and near-bluff homes face brutal northwest wind exposure that drives heating loads far above what inland Cook County suburbs see just a few miles west. Summers are moderated by the lake but humid, so dehumidification capacity matters for high-end homes. Our technicians understand these loads because we have worked on hundreds of Winnetka properties, from the estate homes along Sheridan Road to the commercial buildings near Green Bay Road. We will be there when we say.

Our Emergency & Commercial HVAC Services in Winnetka
24/7 Emergency HVAC
Boilers do not fail on schedule. When a one-pipe steam system starts banging at 11 p.m. in a 1920s Tudor off Sheridan Road, or a furnace quits during a January blizzard, our emergency line connects you to a live person who dispatches a technician trained for Winnetka’s specific heating challenges. We carry main vents, condensate return fittings, and low-water cutoff replacements on our trucks because we know what fails in these homes. A square deal: the price quoted is the price paid, even at 2 a.m.
Commercial HVAC
Winnetka’s commercial buildings - small professional offices, retail along Green Bay Road, churches, and municipal facilities - need reliable climate control without disrupting operations. Our commercial team handles rooftop units, split systems, and boiler plants with the same upfront pricing and 90-Day Done Right Promise we offer homeowners. We schedule around your business hours and minimize downtime because we know Winnetka’s commercial tenants expect consistency.
Rooftop Unit Service
Commercial rooftop units in Winnetka take a beating from lakefront wind and temperature swings. We inspect, repair, and replace RTUs with fast turnaround, and we maintain inventory of common components for brands like Lennox and York to avoid delays. Regular maintenance on these units prevents the mid-July failure that closes a business for days.
Chiller Service
For Winnetka’s larger commercial and institutional buildings, chiller reliability is non-negotiable. Our technicians diagnose refrigerant issues, compressor problems, and control failures with the same methodical approach we bring to historic residential steam systems. We do not guess. We find the problem, quote the repair, and stand behind it.
HVAC Inspection
Before you buy a Winnetka estate or sign a commercial lease, our HVAC inspection reveals what the listing agent will not. We assess boiler condition, steam venting, ductwork capacity in added wings, and whether aging equipment can handle the lakefront heating load. The report is straight talk about repair versus replace, with real numbers attached.

Common Emergency & Commercial HVAC Problems We See in Winnetka Homes
- Clogged or undersized main vents on one-pipe steam systems. In Winnetka’s pre-WWII estate homes near Sheridan Road and the lakefront bluff, improperly sized main vents cause violent banging and uneven heat - a failure mode almost nonexistent in newer suburbs with forced-air heating. We carry the correct vent sizes and know how to balance steam distribution without disturbing historic interiors.
- Older commercial-grade boilers failing during peak winter. Weil-McLain and Burnham boilers in estate homes often fail due to neglected sediment buildup or faulty low-water cutoffs. These units need annual inspection and flushing that many homeowners overlook until the house goes cold.
- Multi-zone ductwork in added wings that cannot keep up. Winnetka’s large homes frequently have decades of additions layered onto original construction. Finished interiors limit duct routing options, and emergency breakdowns happen when the original system is undersized for the expanded footprint.
- Lakefront wind exposure overwhelming heating capacity. Northwest winds off Lake Michigan drive heat loss far above standard calculations. Systems that perform adequately inland may fail on the bluff, especially in older homes with minimal insulation in original walls.

FAQs - Emergency & Commercial HVAC in Winnetka
Banging radiators in Winnetka’s older homes almost always mean clogged or undersized main vents on a one-pipe steam system, or a sagging pipe trapping condensate. The steam hits the water pocket and hammers. During a January cold snap, we responded to a 1920s Tudor on Sheridan Road where the owner reported banging pipes and three cold bedrooms. We found the original one-pipe system had two clogged main vents and a leaking condensate return. We professionally cleaned the vents, replaced the faulty return coupling, and rebalanced the steam distribution - restoring even heat without replacing the entire system. The home’s intact plaster walls and millwork remained undisturbed. Call (833) 983-1671 for a free diagnosis - estimates are free.
Yes, and we do it regularly in Winnetka. Ductless mini-split systems or high-velocity small-duct systems can cool historic homes without tearing open finished walls. We have installed systems in Georgians and Tudors where conventional ductwork would destroy original plaster and millwork. The key is matching capacity to the home’s specific cooling load, which varies significantly between lakefront and inland Winnetka properties. Call (833) 983-1671 for a free assessment of your home’s options.
Yes. We maintain and repair commercial systems for professional offices, retail spaces, churches, and municipal buildings throughout Winnetka. Our commercial technicians handle rooftop units, boiler plants, and split systems with scheduling that respects your operations. Upfront pricing applies to commercial work too - the price quoted is the price paid. Call (833) 983-1671 to discuss your building’s needs.
Annually, before heating season begins. Winnetka’s steam and hot-water boilers - especially the older commercial-grade units in estate homes - accumulate sediment and develop scaling that reduces efficiency and risks failure. Annual inspection includes checking low-water cutoffs, testing safety controls, cleaning burners, and assessing venting. For homes with one-pipe steam systems, we also verify main vent sizing and condensate return condition. The $89 seasonal tune-up includes this full inspection. Call (833) 983-1671 to schedule before the first cold snap.
First, check your thermostat settings and circuit breaker. If those are correct and the furnace still will not fire, call us immediately at (833) 983-1671 - a live person answers 24/7, including during blizzards. Do not attempt to diagnose gas valves, ignition systems, or heat exchangers yourself - these components pose real safety risks and require trained evaluation. Our technicians carry parts for common furnace failures and aim to restore heat in a single visit, even in severe weather. We will be there when we say.
