Trusted Emergency & Commercial HVAC for Chicago Homeowners
When your boiler quits at midnight in January or your rooftop unit fails before a restaurant opening in the Loop, you need a company that answers the phone and shows up. Fireside Heating & Air Co. has handled Best Emergency & Commercial HVAC in Chicago, IL calls for over 42 years, and a live person picks up our line 24 hours a day, every day. We’re at your door when we say we will be, with journeyman-trained technicians who carry the parts to fix most failures in a single visit.
Chicago’s lake-effect winters and humid summers don’t give your system any margin for error. We’ve pulled homeowners out of freeze-ups in Bridgeport, restored cooling to senior living facilities in Grand Boulevard, and kept commercial kitchens running in the Near South Side. Our 90-Day Done Right Promise means the repair is backed in writing - if it’s not right, we make it right, no paperwork, no arguing. Call (833) 983-1671 and you’ll reach a person, not a menu.
What Our Emergency & Commercial HVAC Service Includes
24/7 Emergency HVAC
A true HVAC emergency is when your system is down and your home or business is becoming unsafe or uninhabitable. In Chicago, that often means a furnace failure below 20 degrees or complete AC loss during a July heat index over 100. Our phones are answered by a live person at 2 a.m., on Christmas morning, during Bears games - whenever you call. We dispatch a background-checked, uniformed technician with a stocked truck, and most emergency repairs in Chicago are completed in one trip because we carry OEM parts for Carrier, Trane, Lennox, and the other major brands we service.
Commercial HVAC
Commercial systems in Chicago face demands residential units never see - multi-zone controls, occupancy sensors, and equipment that runs 16 hours straight in a retail space or restaurant kitchen. We’ve maintained and repaired commercial split systems, packaged units, and complex zoned setups in storefronts from Brighton Park to West Town. Our technicians work around your business hours, quote upfront pricing before any work begins, and understand that downtime costs you revenue. The price quoted is the price paid, full stop.
Rooftop Unit Service
Rooftop units are the workhorses of Chicago’s commercial buildings, exposed to lake winds, summer hail, and winter ice buildup that flatlanders never deal with. We service RTUs on low-rise buildings throughout McKinley Park, Douglas, and the Chicago Loop, handling everything from economizer failures to refrigerant leaks and blower motor replacements. Our technicians are trained on fall protection and roof access protocols - this is not work for a general handyman. If your RTU is short-cycling, leaking water through ceiling tiles, or blowing warm air in cooling mode, we’ll diagnose it and quote the repair honestly.
Chiller Service
Chillers serve larger commercial properties in Chicago - hospitals, schools, manufacturing facilities, and multi-story office buildings. These are complex, high-capacity systems where a small refrigerant imbalance or a failing compressor can cascade into a complete shutdown. Our journeyman technicians understand chiller controls, cooling tower integration, and the specific demands of Chicago’s summer humidity spikes. We don’t guess at chiller problems; we pressure-test, measure subcooling and superheat, and give you straight talk about whether repair or replacement makes financial sense.
Annual Maintenance
Annual maintenance is how you avoid the 2 a.m. emergency call entirely. In Chicago, we recommend furnace maintenance in early fall before the first hard freeze, and AC maintenance in spring before the humidity arrives. Our $89 seasonal tune-up includes complete system inspection, cleaning, safety testing, and written condition report - and for seniors and veterans, that drops to $84.55 with our permanent 5% discount. We’ve found cracked heat exchangers in Douglas homes that would have sent carbon monoxide into bedrooms, and caught refrigerant leaks in South Lawndale that would have destroyed compressors. Maintenance is cheaper than repair, and repair is cheaper than replacement.
HVAC Inspection
An HVAC inspection gives you the full picture of what you own and what it needs - whether you’re buying a home in New City, selling a property in Lower West Side, or simply want to know where you stand. We inspect ductwork condition, airflow balance, electrical connections, gas pressure and combustion, refrigerant charge, and thermostat calibration. You get a written report with photographs and prioritized recommendations. No pressure, no upsell - just the facts, so you can plan and budget.

Brands We Service for Emergency & Commercial HVAC
We’ve worked on Carrier equipment since the early 1990s, back when their WeatherMaker furnaces were the standard in Chicago’s new construction. We know the common failure points in Carrier’s variable-speed blowers, we stock their OEM igniters and pressure switches, and we’ve replaced dozens of their heat exchangers under warranty in homes from Grand Boulevard to Brighton Park. Trane is another brand we’ve serviced for decades - their XV20i variable-speed systems are built to last, but when the communicating control board fails, you need a technician who understands their proprietary protocol, not someone swapping parts and hoping.
Lennox makes some of the most efficient equipment on the market, and we’ve installed and repaired their Dave Lennox Signature Collection systems in high-end renovations across the Near South Side and Chicago Loop. Goodman has earned its place as a reliable value brand, and we keep their most common capacitors, contactors, and blower motors on our trucks because Goodman units are everywhere in Chicago’s older housing stock. Whether you have Carrier, Trane, Lennox, Goodman, or any other make - Rheem, York, Daikin, Bryant, or American Standard - we can help. We don’t turn jobs away because of the label on the cabinet.
Signs You Need Emergency & Commercial HVAC Right Now
- No heat on a sub-freezing Chicago night. When the temperature drops below 20 degrees and your furnace won’t fire, your pipes are at risk within hours. We’ve responded to emergency no-heat calls in Bridgeport and McKinley Park where the thermostat read 38 degrees inside - that’s not uncomfortable, it’s dangerous. Call us immediately; we’ll guide you through any immediate safety steps while a technician is en route.
- Complete AC failure during a heat advisory. Chicago’s summer humidity is hard on the elderly and anyone with respiratory conditions. If your air conditioner is blowing warm air or not running at all and the heat index is over 95, that’s an emergency. We carry replacement capacitors, contactors, and refrigerant to restore cooling fast.
- Loud grinding or screeching from your HVAC unit. These sounds mean mechanical failure in progress - a seized motor, failing bearings, or a blower wheel coming apart. Continuing to run the system will destroy additional components and double your repair bill. Shut it off and call us.
- Water leaking through ceilings or walls. In commercial buildings with rooftop units, a clogged condensate drain or cracked drain pan can dump gallons of water into your space. In homes, a frozen evaporator coil that thaws can overflow the secondary drain. Water damage spreads fast in Chicago’s older plaster and lathe construction. This needs same-day attention.
- Burning smell or electrical burning odor. Any smell of burning from your HVAC system indicates an electrical problem - overheating motor, failing capacitor, or compromised wiring. This is a genuine fire hazard. Turn the system off at the breaker and call (833) 983-1671. Do not attempt to diagnose this yourself.
Our Emergency & Commercial HVAC Process - Step by Step
- 1
You call, a person answers. No voicemail tree, no “press 1 for service.” A live person at Fireside Heating & Air Co. takes your information, asks the right questions to understand urgency, and dispatches the nearest available technician. In Chicago, our typical emergency response time is under two hours.
- 2
Upfront diagnosis and pricing. Our technician arrives in a marked vehicle, in uniform, with shoe covers already on. We inspect your system, identify the root cause - not just the symptom - and give you a written, itemized quote before any work begins. The price quoted is the price paid. If you have a written estimate from another company, we’ll give you a free second opinion.
- 3
Repair with OEM parts. We carry thousands of parts on our trucks, sourced directly from manufacturers or authorized distributors. For commercial systems and chillers, we may need to source specialized components, but we’ll tell you honestly if that’s the case and give you a realistic timeline.
- 4
Testing and verification. After repair, we don’t just pack up. We run the system through its full cycle, measure temperatures at supply and return registers, check amp draws on motors, and verify proper operation of safety controls. In commercial applications, we document everything for your maintenance records.
- 5
Written guarantee and follow-up. Every repair is backed by our 90-Day Done Right Promise - in writing, no arguing, no paperwork if something isn’t right. We also note any maintenance items or wear that may need attention soon, so you can plan ahead instead of being surprised.
How Much Does Emergency & Commercial HVAC Cost in Chicago?
A typical emergency HVAC repair in Chicago runs $150-$700 depending on what’s failed and when you need us. After-hours and holiday calls carry the same labor rate - we don’t gouge you because your furnace quit on New Year’s Eve. Commercial repairs and rooftop unit service typically fall in the $200-$650 range for standard component failures; chiller repairs are quoted individually based on system size and complexity. Our $89 seasonal tune-up is the best prevention money you can spend, and with our standing offer of $50 off any repair over $250, a maintained system that needs a mid-season fix still costs less than most competitors charge for the repair alone.
Several factors affect what you’ll pay. The age of your equipment matters - parts for 25-year-old furnaces are harder to source and more expensive. Accessibility counts too; a rooftop unit in the Loop with limited crane access costs more to service than a ground-level residential condenser in South Lawndale. The scope of the problem is the biggest variable - a failed capacitor is a quick fix, a cracked heat exchanger or compressor replacement is major surgery. We give you straight talk about repair versus replace, and we’ll never recommend replacement when repair is the smarter money.
Our estimates are free, detailed, and valid for 30 days. You’ll know exactly what’s included, what parts we’ll use, and how long the work takes. No hidden fees, no surprise charges when the invoice arrives. Call (833) 983-1671 for your exact quote.

Clear a path to your indoor unit and outdoor condenser if safely accessible, and note any unusual sounds, smells, or behaviors the system displayed before failing. For commercial properties, ensure roof access is available and any security systems are notified. Have your previous service records handy if you have them.
