Why Fireside Heating & Air Co. of Chicago Is Arlington Heights’s Preferred Emergency & Commercial HVAC Company
Forty-two years in this trade teaches you which suburbs have which problems. Arlington Heights’s post-WWII building boom - concentrated heavily in the 1960s and 1970s - produced one of the northwest suburbs’ densest pockets of split-level and raised-ranch homes, particularly across the 60004 and 60005 ZIPs. These homes are now cycling through second- or third-generation HVAC replacements, and the original ductwork was sized and routed for far looser efficiency standards, meaning duct assessment and airflow balancing are as consequential as equipment selection on nearly every replacement job here. We have done hundreds of them. We know where the returns are missing before we pull the panel.
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They carry parts for Carrier, Trane, Lennox, and Goodman systems on every truck, and most Arlington Heights repairs finish in a single visit. The 90-Day Done Right Promise backs every job in writing - if it is not right, we make it right, no paperwork, no arguing. That is the Keystone Standard, and it has not changed since Terry Kowalski founded Fireside in 1984.
We also understand the commercial side of Arlington Heights. The strip centers along Golf Road, the office buildings near the Metra corridor, the light industrial pockets south of the Northwest Tollway - these properties run rooftop units and small chillers that cannot wait until Monday. Our emergency line rings to a live person at 2 a.m. on a Sunday, same as Tuesday afternoon. We will be there when we say.
Our Emergency & Commercial HVAC Services in Arlington Heights
24/7 Emergency HVAC
Furnace failure at -4°F. AC down when the dewpoint hits 70°F. These are not inconveniences in Arlington Heights; they are urgent problems, especially for the older residents in the ranch neighborhoods near Recreation Park who cannot safely wait. Our phones are answered by a live person 24 hours a day, 7 days a week, including holidays. We dispatch from our Chicago base and typically reach Arlington Heights within the hour. The price quoted is the price paid. No fine print.
Commercial HVAC
Arlington Heights businesses along Rand Road and the commercial corridors near Arlington Downs depend on consistent climate control for employees, inventory, and customers. We service packaged rooftop units, split systems, and light commercial chillers. Our technicians are trained on nine major brands and carry common failure parts - capacitors, contactors, blower motors, control boards - to minimize downtime. We also handle seasonal changeovers and preventive maintenance contracts for local property managers who need the job done without supervising the crew.
Rooftop Unit Service
The flat-roof commercial buildings near Arlington Park and along Northwest Highway run Carrier, Trane, and Lennox rooftop units that take a beating from northwest suburban wind exposure and thermal cycling. We perform leak detection, refrigerant recovery, economizer repair, and full compressor replacement. Access is never an excuse - we bring the lifts, the rigging, and the experience. One trip, done right.
Chiller Service
Small commercial chillers in Arlington Heights office and medical buildings require specialized handling. We troubleshoot low-pressure faults, clean condenser tubes, replace refrigerant charges to factory spec, and verify capacity against design loads. Arlington Heights’s summer latent loads - those 70°F dewpoints - mean your chiller must remove moisture, not just drop temperature. We check both.
Annual Maintenance
The best emergency call is the one you never have to make. Our $89 Seasonal Tune-Up covers full inspection, cleaning, and calibration for furnaces, air conditioners, and heat pumps. For Arlington Heights’s 1960s and 1970s homes, we also assess ductwork condition and airflow balance - catching the missing returns and undersized supplies before they force a midwinter breakdown. Senior and veteran customers receive 5% off, always.

Common Emergency & Commercial HVAC Problems We See in Arlington Heights Homes
- Missing return-air paths in split-level lower levels. On split-level jobs throughout 60004, local techs consistently find that the lower-level family room was never given a dedicated return - a 1960s construction shortcut that causes chronic “cold downstairs, stuffy upstairs” complaints and means the new system will underperform on day one unless a return is added before the install is signed off.
- Oversized workshop or detached garage HVAC units starved for airflow. Original ductwork was sized for the house only, not the add-on space. The unit short cycles, fails prematurely, and never reaches setpoint. We resize or add dedicated systems.
- Heavy-duty commercial doors and envelope failures. In acreage properties with detached workshops, worn torsion springs on commercial-grade doors jam open, leaving the HVAC system cycling against uncontrolled infiltration. We coordinate with our door specialists or flag the issue for your contractor.
- DIY thermostat swaps miswiring zoning panels. Self-reliant homeowners in Arlington Heights’s older neighborhoods attempt their own upgrades but cross low-voltage wiring on multi-level systems, frying control boards and triggering emergency callouts. We replace the board, trace the wiring, and get the zones speaking to each other again.

FAQs - Emergency & Commercial HVAC in Arlington Heights
The original 1960s builders frequently omitted dedicated return-air paths from lower-level family rooms, so heated air rises and stagnates upstairs while the thermostat downstairs never senses recovery. We add return drops and rebalance supply registers before signing off any replacement in these homes. Call (833) 983-1671 for a free duct assessment.
Yes. We service packaged rooftop units throughout the Arlington Downs commercial corridor and surrounding properties, with lift equipment and factory-trained technicians for Carrier, Trane, Lennox, and other major brands. Most repairs complete same-day. Call (833) 983-1671 to schedule.
Short cycling in a 60004 workshop usually means the unit was added to ductwork sized only for the main house, starving the add-on for airflow and causing the compressor to hit high-pressure limits. Typical repair runs $150-$650 if it is a control or airflow issue; dedicated system installation may reach the $3,500-$7,500 range if the house duct cannot be adapted. We measure static pressure and quote both paths. Call (833) 983-1671 for an exact diagnosis.
No-heat calls from failed ignition components or induced draft motors, usually on furnaces 15-25 years old in the ranch and split-level neighborhoods near Recreation Park and along Euclid Avenue. Arlington Heights’s -4°F design heating temperature means an overnight failure becomes urgent fast. We answer live 24/7 and carry replacement parts for same-day restoration. Call (833) 983-1671.
Yes. We provide preventive maintenance contracts for commercial properties along Rand Road, Golf Road, and the Northwest Highway corridor, covering rooftop units, chillers, and split systems. The $89 Seasonal Tune-Up applies to residential; commercial contracts are quoted to building size and equipment count. Call (833) 983-1671 for a custom proposal.
We responded to a late-night emergency call at a raised ranch on S Wilke Avenue in 60005: the owner’s two-ton Carrier condenser had frozen solid because the 1970s ductwork had no return in the finished basement. We added a return drop, replaced the metering device, and recharged to factory specs - one trip, no callbacks. That is how we work.
