Why Chicago Homeowners Choose Fireside Heating & Air Co. of Chicago
We’ve been in Chicago long enough to know that a homeowner in their sixties who’s lived in the same Portage Park bungalow for thirty years doesn’t want a sales pitch. They want someone who shows up when promised, puts on shoe covers without being asked, and quotes a price that doesn’t change when the bill arrives.
Our technicians are trained journeymen, background-checked and uniformed, and they work in your home the way they would in their own mother’s. Every repair and installation is backed by our 90-Day Done Right Promise - in writing, no paperwork, no arguing. If it’s not done right, we make it right. That’s the Keystone Standard, and we’ve applied it to every job since we opened our doors here.
We answer calls live, 24 hours a day, 7 days a week. Nights, weekends, holidays - never a voicemail tree. Most repairs are completed in a single visit, and we service nine major brands including Carrier, Trane, and Lennox. Our customers in Logan Square and Streeterville know we’ll be there when we say.
HVAC Services We Offer in Chicago
AC Repair & Installation in Chicago
Chicago summers can swing from mild to brutal overnight, and that lakefront cooling effect doesn’t reach every neighborhood equally. We repair and replace central air systems, handle full installations in homes with existing ductwork, and engineer solutions for the many Chicago properties that were never built for forced air. Learn more about our AC Repair & Installation in Chicago.
Heating & Furnace in Chicago
With roughly 6,350 heating degree days annually, Chicago’s heating season is long and unforgiving. We service gas and electric furnaces, but we also maintain and replace the aging cast-iron boilers still heating thousands of bungalows and two-flats across the city - equipment many out-of-town technicians have never touched. Learn more about our Heating & Furnace in Chicago.
Heat Pump & Mini Split in Chicago
For homes without ducts - which describes a significant share of Chicago’s pre-1940 housing stock - ductless mini-splits offer real heating and cooling without tearing apart plaster and brick. We size these systems carefully, accounting for Chicago’s low-ambient winter limits and the load differences between a lakefront condo and an inland bungalow. Learn more about our Heat Pump & Mini Split in Chicago.
Air Quality & Ventilation in Chicago
Chicago’s industrial legacy, pollen cycles from the lakefront parks, and tightly sealed vintage homes create air quality challenges that vary by neighborhood. We install humidifiers, dehumidifiers, air purifiers, and ventilation solutions sized for your actual space and the people breathing in it.
Emergency & Commercial HVAC in Chicago
When the boiler dies at midnight in January or your commercial tenant’s heat fails the week before the city’s September 15 heating deadline, we answer the phone and we roll. Our 24/7 live-answer policy applies to every call, residential or commercial, with upfront pricing and no after-hours gotchas.
Neighborhoods We Serve in Chicago

- Portage Park - classic Chicago bungalows, many with 40- to 60-year-old cast-iron boilers

Why Chicago’s Climate & Housing Affect HVAC
Chicago’s housing stock is dominated by an estimated 80,000 brick Chicago bungalows and tens of thousands of two-flats and three-flats built between 1910 and 1940 - nearly all originally heated by steam or hot-water radiator boilers with zero ductwork. This means a central air conditioning retrofit in a large swath of Chicago’s neighborhoods is never a simple equipment swap; it requires either fabricating and running an entirely new duct system through a brick structure or installing ductless mini-splits, a complexity and cost that defines the trade here in a way that simply doesn’t exist in newer Sun Belt metros.
The archetypal Chicago dwelling was built for steam or hot-water radiant heat, leaving no duct infrastructure for forced-air systems. Aging cast-iron boilers in these buildings, many 40-60+ years old and scaled up from decades of Chicago’s moderately hard Lake Michigan water, represent a primary service and replacement category that technicians in most other cities rarely encounter at this volume. Lake Michigan itself creates measurable microclimates where lakefront neighborhoods run 10-15°F cooler than inland areas on summer afternoons, meaning a Manual J load calculation for a Logan Square home and a Streeterville condo a few miles east are meaningfully different despite being in the same city.
Then there’s the legal calendar. Chicago’s Residential Landlord and Tenant Ordinance requires landlords to maintain at least 68°F from September 15 through June 1. Every mid-September, HVAC companies across the city see a predictable surge of emergency boiler and furnace calls as landlords fire up systems that sat idle all summer and discover cracked heat exchangers, failed pilot assemblies, or seized circulator pumps. It’s a legally-driven seasonal failure wave tied directly to a specific local ordinance date, and we’ve learned to staff for it.

FAQs About HVAC in Chicago
Most standard HVAC repairs in Chicago fall between $180 and $450, with furnace and boiler work often landing in the higher end due to the age and accessibility of equipment in the city’s vintage housing stock. Complex boiler repairs in bungalows or two-flats can reach $600-$900 when scaled cast-iron sections or hard-to-source pilot assemblies are involved. Call (833) 983-1671 for a free, exact quote - estimates are free, and we honor $50 off any repair over $250.
Yes, but it is rarely a simple equipment swap - Chicago’s 80,000+ brick bungalows were built for radiant heat with no duct infrastructure, so central air requires either fabricating and running new ductwork through brick and plaster or installing a ductless mini-split system. Most homeowners we speak with in Portage Park and Logan Square find that multi-zone ductless systems cost less, disrupt less, and heat and cool more efficiently than a full duct retrofit. We assess your specific layout and give you both options with upfront pricing.
If you’re a Chicago landlord, you’re likely hitting the city’s legally mandated September 15 heating deadline after a summer of system dormancy. Cast-iron boilers that sat idle for months often reveal cracked heat exchangers, failed pilot assemblies, or seized circulator pumps when fired up under pressure - a seasonal failure wave we see every year. We recommend a pre-season inspection in late August to catch these issues before the ordinance clock starts.
For a furnace under twelve years old, repair is usually the better value; beyond fifteen years, especially with Chicago’s brutal heating demand, replacement often saves money over a few seasons of rising repair bills and declining efficiency. We give straight talk about repair versus replace, never pressure, and our free second opinion on any written estimate helps you know you’re getting a square deal. Call (833) 983-1671 to discuss your specific system.
Yes - our phones are answered live 24 hours a day, 7 days a week, and our typical emergency response time across Chicago is under two hours. Polar Vortex events and the mid-September landlord rush can create brief spikes, but we staff for Chicago’s predictable seasonal surges and we do not leave homeowners without heat in January. Call (833) 983-1671 now; a live person will answer.

What Chicago Customers Say
"The thermostat had been miswired by whoever installed it, so the heat strips were running with the AC. He found it in a few minutes and probably saved me a fortune on the next few bills."
- Nicole Fletcher"Blower motor on a twelve year old furnace. He gave me the honest math on repair against replace and did not push me toward the bigger ticket."
- Paige Hoffman"The maintenance plan is actually worth it. They turn up twice a year and the last visit caught a refrigerant leak before it became a July disaster."
- Kurt Anderson
