We’re Fireside Heating & Air Co. of Chicago, and our Emergency & Commercial HVAC team has been serving Addison since 2018. Call us at (833) 983-1671 - a live person picks up, 24 hours a day, every day of the year.
Addison is unusual among DuPage County suburbs. Dense 1950s-1970s residential tracts sit shoulder-to-shoulder with light-industrial and warehouse corridors along Lake Street and Army Trail Road. That dual landscape means local HVAC contractors must speak two languages: aging residential forced-air systems and commercial rooftop units that keep production lines moving. We’ve spent four decades learning both.
Our technicians know the tight clearances of Addison’s post-war ranches and split-levels, the alley-load access points behind townhomes, and the flat-roof commercial buildings where a downed RTU can halt an entire overnight operation. We carry parts for Carrier, Trane, Lennox, and the other major brands on every truck, and most jobs finish in a single visit.
Why Fireside Heating & Air Co. of Chicago Is Addison’s Preferred Emergency & Commercial HVAC Company
We’ve worked in Addison long enough to remember when the industrial corridor along Lake Street was still farmland. That history matters. When you call us, you’re not getting a dispatcher in another state reading from a script. You’re getting a company that knows Army Trail Road traffic patterns, understands DuPage County permit requirements, and has replaced furnaces in the same Birchwood Avenue split-levels three times over as systems aged out.
Addison’s 24/7 industrial and residential mix means emergency HVAC calls often spike during overnight shifts at the Lake Street warehouses, where a downed rooftop unit can halt production immediately. We keep technicians staged for those calls. Our 90-Day Done Right Promise applies to every repair and installation - if it’s not right, we make it right, in writing, with no paperwork and no arguing.
Our phones are answered by a live person around the clock, including the 2 a.m. no-heat emergency. Background-checked, uniformed technicians arrive in marked vans, put on shoe covers without being asked, and treat your home or business the way they would their own mother’s. The price we quote is the price you pay. Full stop.
Our Emergency & Commercial HVAC Services in Addison
24/7 Emergency HVAC
Emergancies don’t wait for business hours, and neither do we. A seized inducer motor on a 15-year-old Carrier furnace in a 1960s split-level can drop the lower level to 50°F overnight. A frozen coil on a rooftop unit serving a Lake Street warehouse can shut down production before dawn. We responded to a midnight emergency at a split-level on Birchwood Avenue near Army Trail Road - the upstairs furnace failed, and our tech found the inducer motor seized. We replaced it with a new Bryant motor and balanced the system to eliminate the split-level temperature gap. Most emergency calls in Addison reach us within the hour, and our trucks carry the parts to finish the job.
Commercial HVAC
Addison’s commercial base runs hard. Warehouses, light manufacturing, and distribution centers along Lake Street and Army Trail Road operate on thin margins where downtime is measured in lost revenue, not just discomfort. We service packaged rooftop units, split systems, and make-up air units for commercial clients throughout the 60101 zip. Our technicians are trained on Goodman, Rheem, York, and the full range of major commercial brands. We understand that a 6 a.m. call about a failed heating system means employees walking into a cold building, and we prioritize accordingly.
Rooftop Unit Service
Rooftop units are the workhorses of Addison’s commercial corridor, and they take a beating. Chicago-area winters push heating cycles hard; summer dew points in DuPage County force latent cooling loads that strain condensate drainage systems. Clogged condensate drains or frozen coils on rooftop units serving Lake Street warehouses are among the most common emergency shutdowns we see. Our techs carry lift-equipped vans for safe roof access and stock common RTU components - compressors, blower motors, control boards, and refrigerant - to minimize downtime.
Chiller Service
For larger commercial facilities in Addison with chilled-water systems, chiller failures can cripple operations fast. We diagnose and repair scroll, screw, and centrifugal chillers, addressing everything from refrigerant leaks to control system faults. Given Addison’s hard water - DuPage County municipal water is among the hardest in the metro - scale buildup in condenser tubes is a recurring maintenance issue we flag early.
Annual Maintenance & HVAC Inspection
The best emergency call is the one you never have to make. Our $89 Seasonal Tune-Up catches worn components before they fail. For commercial clients, we build maintenance schedules around your production calendar, not ours. And because DuPage County water hardness calcifies humidifier panels faster than softer-water markets, our fall maintenance in Addison always includes humidifier inspection and descaling - a detail that prevents mid-winter callbacks.

Trusted Brands We Service in Addison
We carry factory-authorized parts and training for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

Our trucks are stocked accordingly.
Common Emergency & Commercial HVAC Problems We See in Addison Homes
- Seized inducer motors on aging furnaces. The 1950s-1970s split-levels that dominate Addison’s residential stock often still run original ductwork with 15- to 20-year-old furnaces. Overnight cold snaps push these systems past their limit, and the inducer motor is typically the first casualty.
- Clogged condensate drains and frozen coils on commercial rooftop units. Lake Street warehouses depend on RTUs for year-round climate control. Summer humidity and winter freeze-thaw cycles clog drain pans and coat coils, triggering emergency shutdowns when production can’t afford them.
- Calcified humidifier panels mid-winter. DuPage County’s hard water destroys bypass and flow-through humidifier water panels faster than almost anywhere in the Chicago metro. We find them fully calcified by January - a maintenance issue that should have been caught in October.
- Uneven temperatures in split-level homes. A single-zone system in a split-level almost always overcools the lower level and underheats the upper. Emergency calls for “no heat upstairs” often trace to airflow imbalance, not equipment failure - and we fix both.

FAQs - Emergency & Commercial HVAC in Addison
Most emergency calls in Addison reach us within the hour, and our commercial clients along Lake Street and Army Trail Road get priority routing for production-critical failures. We stage technicians to cover overnight shifts when RTU failures are most disruptive. Call (833) 983-1671 - a live person answers, and we’ll give you an exact ETA.
Split-level layouts create natural airflow imbalances because a single thermostat controls zones with different heat loads and duct runs. In Addison’s 1950s-1970s housing stock, the original ductwork is frequently undersized for the upper level. We can often correct this with airflow balancing, duct modifications, or zoning solutions during an emergency call - not just patch the symptom. Call (833) 983-1671 and we’ll assess what’s possible.
Yes. We repair scroll, screw, and centrifugal chillers for commercial facilities throughout the 60101 zip, including refrigerant leaks, control faults, and condenser tube scaling from DuPage County’s hard water. After-hours chiller emergencies get the same live-answer dispatch as residential calls. Call (833) 983-1671 for immediate response.
Yes - especially given Addison’s hard water and aging housing stock. Our $89 seasonal tune-up catches calcified humidifier panels, worn furnace components, and RTU drain issues before they trigger emergency shutdowns. Commercial clients benefit from scheduled maintenance that avoids production interruptions. Call (833) 983-1671 to schedule.
We service all nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.
