When your furnace quits at midnight in January or your warehouse AC fails on a 95-degree July afternoon, you need a company that answers the phone and shows up. We do both. Fireside Heating & Air Co. has dispatched our Emergency & Commercial HVAC team to Aurora for over 8 years, and we know the city block by block. From the post-war ranches near Buckley Air Force Base to the new commercial corridors along E-470, we carry the parts and the know-how to finish most jobs in a single visit. Call (866) 561-3358 anytime - a live person picks up, 24 hours a day, including holidays.
Why Fireside Heating & Air Co. Is Aurora’s Preferred Emergency & Commercial HVAC Company
Aurora is not a city you learn from a map. The east-west split here is unlike anything you’ll find in Centennial or Denver proper, and we’ve been driving it since 2018. Our technicians have replaced furnaces in the original 1960s ranch homes of Del Mar Parkway and commissioned rooftop units in the warehouse districts near Denver International Airport - all within the same city limits, often in the same week.
Homeowners in Aurora call us back because we diagnose the real problem. In 80010 and 80011, we’ve learned that chronic hot spots are rarely the equipment’s fault. The ductwork was sized for a swamp cooler in 1968, not a refrigerated air system installed in 1995. We say so upfront. We quote the full fix, not a band-aid. Our 90-Day Done Right Promise means if we miss something, we make it right - in writing, no paperwork, no arguing.
Our phones are answered by a live person around the clock. Not a voicemail tree. Not a call center in another state. When you call (866) 561-3358 at 2 a.m., you reach someone who can dispatch a background-checked, uniformed technician to Aurora within the hour for true emergencies. We’ve done it for four decades.
Our Emergency & Commercial HVAC Services in Aurora
24/7 Emergency HVAC
Heating and cooling emergencies in Aurora don’t wait for business hours. Chinook winds can crack a heat exchanger in hours. A failed compressor in August turns a home in 80011 unlivable by afternoon. We answer every call live, day or night, and stock trucks for the specific failures we see in Aurora’s split housing stock. Most emergency calls in western Aurora involve older furnaces pushed past their limit; in eastern ZIPs like 80019, we see newer systems with failed capacitors or control boards. We carry both.
Commercial HVAC
Aurora’s commercial base has exploded along the E-470 corridor, but the building stock is uneven. Warehouses in 80019 often have builder-grade rooftop units that were minimally sized for elevation and load. When a 100-degree day hits, those compressors fail prematurely. We size replacements correctly for 5,400 feet, derating gas equipment per code and calculating actual peak loads rather than relying on builder specs. We also service existing commercial systems across Aurora’s older business districts, from strip malls near Colfax to industrial parks south of I-70.
Rooftop Unit Service
Rooftop units are the workhorse of Aurora commercial properties, and they’re exposed. High Plains wind, hail, and rapid temperature swings stress coils and economizer controls. We service Rheem, York, Daikin, and Bryant rooftop units common in Aurora commercial installations, with parts on the truck for the most frequent failures. A seized economizer damper or refrigerant leak doesn’t need to shut your business down for two days. We aim for same-day resolution.
Chiller Service
Not every Aurora HVAC company touches chillers. We do. Commercial properties with process cooling or large-scale climate control - medical facilities, data-adjacent operations, certain manufacturing - rely on chillers that can’t wait. Our technicians are trained to diagnose chiller circuits, refrigerant loops, and control sequences. If your Aurora commercial property runs a chiller, we can service it, repair it, or advise honestly on replacement versus continued repair.
HVAC Inspection
Before you buy a commercial property in Aurora or renew a lease, an HVAC inspection by someone who knows this market is worth the call. We document equipment age, elevation derating compliance, ductwork condition, and whether that “recently serviced” rooftop unit was actually serviced or just hosed off. In 80016 and 80019, we’ve found builder-grade equipment already failing at year eight because it was never properly commissioned for altitude. We put it in writing.

Trusted Brands We Service in Aurora
We train our technicians as journeymen on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Aurora customers, this means we stock common parts locally rather than ordering from Denver and waiting two days. A failed ignition module on a York furnace in 80017 or a refrigerant leak on a Daikin rooftop unit near Peoria Street - we likely have what we need on the truck. If we don’t, our supplier relationships get us same-day or next-morning parts for brands we service regularly. No brand loyalty required. We fix what you have, and we fix it right.
Common Emergency & Commercial HVAC Problems We See in Aurora Homes
- Chronic hot spots misdiagnosed as equipment failure. In western Aurora’s 80010 and 80011 ZIPs, we regularly find homes where a 1960s evaporative cooler was converted to refrigerated air using original undersized ductwork. The compressor works fine. The ducts can’t move enough air. Homeowners have paid for two or three service calls before someone measured static pressure.
- Heat exchanger cracks after Chinook thermal cycling. Aurora’s temperature can swing 40°F in hours when Chinook winds descend. Older furnaces in the 80011 corridor, especially 1980s and 1990s models, develop heat exchanger stress fractures from repeated rapid expansion and contraction. We check every furnace we touch with a camera inspection.
- Premature compressor failure in eastern Aurora commercial units. Builder-grade rooftop units on warehouses in 80016 and 80019 were often sized using sea-level calculations. At 5,400 feet, the compressor runs harder, longer, and fails sooner. We see five-year compressors dead at year three.
- Whole-building dryness and static damage. Aurora’s annual humidity averages around 30%. Forced-air systems without whole-house humidification create environments where wood cracks, electronics fail, and occupants suffer. We don’t treat humidification as an upsell here. It’s a functional necessity for system longevity and occupant health.
Heating and Cooling in Aurora, Done Right
Denver Metro winters start sharp and summers climb fast. Your furnace works hard at altitude, and that first heat wave tests every builder-grade AC that came with the tract house. Fireside keeps Aurora homes steady through both, with journeymen who size the fix honestly, tape the boot seams, and leave the thermostat where they found it.
We named this company for the warmest word in the American memory because that’s the feeling we deliver, backed by our 90-Day Done Right Promise in writing. we coordinate through our Denver Metro service area Same-day service when the season turns. Ask about our $89 seasonal tune-up.
Heating & Cooling in Aurora
Colorado’s altitude swings and dry winters punish furnaces hard, then the first June heat wave tests every AC that sat idle for eight months. We see it every season: builder-grade units in tract housing aging past their design life, coils clogged from cottonwood season, no-heat calls at 2 a.m. when the temperature drops forty degrees overnight. Our techs are licensed, insured journeymen who give you honest math on repair versus replace, put on shoe covers without being asked, and leave the price where you can read it. we coordinate through our Denver Metro service area

FAQs - Emergency & Commercial HVAC in Aurora
The ductwork was originally sized for an evaporative cooler, not refrigerated air. In the 1960s and 1970s, these homes moved air through small trunks at low static pressure; when a refrigerated AC system was added later, the existing ducts couldn’t handle the higher pressure and airflow requirements. We measure static pressure on every 80010 call and quote duct modification if the numbers don’t match the equipment spec. Call (866) 561-3358 for an inspection - estimates are free.
Yes. Aurora sits at roughly 5,400 feet, and gas furnaces must be derated approximately 4% per 1,000 feet above sea level to maintain safe combustion and rated output. An out-of-market contractor who installs sea-level equipment here will deliver roughly 78% of rated capacity and risk incomplete combustion. We derate every gas installation per code, and we check existing equipment for proper orifice sizing during tune-ups. Call (866) 561-3358 to schedule.
Premature compressor failure in undersized rooftop units, especially in eastern Aurora’s 80016 and 80019 warehouse districts. Builder-grade equipment was often minimally sized for cost, then further handicapped by altitude derating that was never applied. The compressor runs at maximum load continuously and burns out. We size replacements using actual load calculations, not builder defaults. Call (866) 561-3358 for emergency commercial service.
Yes. Our technicians are trained to diagnose and repair commercial chillers, including refrigerant circuit work, control sequencing, and cooling loop issues. Not every Aurora HVAC company maintains this capability. If your commercial property relies on process cooling or large-scale chilled water, we can inspect, repair, or advise on replacement. Call (866) 561-3358 to discuss your system.
True emergencies - no heat below 40°F, no cooling above 90°F, or any safety concern like a cracked heat exchanger - typically receive same-day response, often within one to two hours depending on current call volume and your location within Aurora. Our phones are answered live 24/7, and we do not route you to voicemail. Call (866) 561-3358 and we’ll give you an honest arrival time.
