We’ve worked across Greeley for decades, from the post-war ranches near the University of Northern Colorado to the newer subdivisions west of 35th Avenue, and we know the territory well enough to solve problems that out-of-town crews miss. That includes the rural properties north and east of city limits where a detached workshop or outbuilding needs its own system, and where an 80-foot gravel drive means you cannot afford a second trip for a forgotten part.

Why Fireside Heating & Air Co. Is Greeley’s Preferred Emergency & Commercial HVAC Company

Fireside Heating & Air Co. has served homeowners and business owners for over 8 years. We were founded in 1984, long before the oil-and-gas boom transformed west Greeley, and we’ve stayed in business by doing what we say we’ll do and standing behind it in writing.

Greeley customers tell us the same thing repeatedly: they called us after another company quoted a cheap fix that failed within the month, or after waiting three days for a callback on an emergency. Our 90-Day Done Right Promise means if it is not done right, we make it right, with no paperwork and no arguing. The price we quote is the price you pay.

Our phones are answered by a live person around the clock, every day of the year, including holidays. When you call at 2 a.m. from a home off O Street or a commercial kitchen on 10th Street, you will reach someone who can dispatch a background-checked, uniformed technician trained as a journeyman. Most jobs are completed in a single visit.

We know Greeley’s housing stock and its problems. East and central Greeley, ZIP codes 80631 and 80632, contains significant post-WWII through 1970s ranch and bungalow construction with original oversized duct runs and gravity-feed furnace footprints that complicate modern retrofits. West Greeley, 80634, saw explosive tract-home growth during the 2000s-2010s Weld County boom, and those builder-grade two-stage systems are now hitting their first major repair cycles all at once. We have replaced and repaired both, many times over.

Our Emergency & Commercial HVAC Services in Greeley

24/7 Emergency HVAC Repair

Furnace failures and AC breakdowns do not follow business hours. We answer emergency calls from Greeley homeowners and businesses every night of the week, including weekends and holidays. Our technicians arrive with fully stocked trucks and the training to service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. On a 40-acre property north of 80631, we replaced a failing roof-mounted RTU serving a detached workshop with a Trane unit, a job made trickier by an 80-foot gravel drive and the need to lift the unit with a boom truck in gusty Chinook winds. The old RTU had formicary corrosion pitting on its copper coils from years of exposure to Greeley’s feedlot-laden air. We completed the job in one day because we arrived with the right equipment and the right coil specification.

Commercial HVAC Service

Greeley’s commercial buildings face conditions that Front Range crews in Fort Collins or Loveland rarely encounter. The ambient air downwind of Weld County’s concentrated feedlot operations, including the JBS/Monfort facilities, carries hydrogen sulfide and ammonia that accelerate formicary corrosion on copper evaporator and condenser coils. We regularly pull condenser coils in Greeley that look years older than their installation date. For commercial clients, this means more frequent inspections, earlier replacement planning, and honest conversations about aluminum-coil alternatives or protective coatings. We service retail spaces on 8th Avenue, restaurants near the university, warehouses in the industrial corridor, and agricultural operations with detached workshops requiring independent climate control.

Rooftop Unit (RTU) Installation and Repair

Greeley’s commercial and light-industrial properties rely heavily on rooftop units for space efficiency and centralized control. We install, repair, and replace RTUs across the city, from aging systems on original downtown buildings to newer units on west Greeley commercial pads. Pricing for RTU replacement varies by tonnage and access, but a typical commercial rooftop unit installation in west Greeley runs $4,500-$12,000 depending on electrical requirements and crane access. We always inspect the existing curb and structural support, because Greeley’s Chinook wind gusts and freeze-thaw cycles stress roof penetrations more aggressively than lower-elevation Front Range cities.

Chiller Service

Commercial properties with process cooling needs, including medical offices and food service operations near 23rd Avenue and 10th Street, depend on reliable chiller performance during Greeley’s increasingly hot summer peaks. We service scroll, screw, and centrifugal chillers, with particular attention to condenser water treatment, because Greeley’s hard water produces rapid mineral scaling that chokes heat exchange efficiency. Our technicians carry water treatment test kits and can recommend local water-softening integration where appropriate.

Annual Maintenance and HVAC Inspection

Annual maintenance is where we catch the problems that become 2 a.m. emergencies. Our $89 Seasonal Tune-Up includes full system inspection, filter replacement, refrigerant charge verification, and combustion safety testing. For commercial clients, we offer structured maintenance agreements with priority scheduling and documented inspection reports for insurance and warranty compliance. In Greeley, we schedule maintenance with particular attention to pre-Chinook season furnace checks and mid-summer AC inspections before the August heat peaks.

Trusted Brands We Service in Greeley

We are trained to service and repair Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. For Greeley customers, this means we stock common parts for Rheem furnaces and York air handlers locally, and we maintain supplier relationships that let us source Heat Pump & Mini Split in Greeley components and Bryant coil assemblies without the multi-day delays that strand other contractors. When your system fails during a cold snap or a heat wave, that parts access determines whether you wait hours or days.

Common Emergency & Commercial HVAC Problems We See in Greeley Homes

• Oversized doors and springs on detached workshops fail from infrequent use and corrosive air. Rural Greeley properties often have outbuildings with heavy-duty overhead doors that sit unused for weeks, then seize when needed. The same sulfur compounds that attack HVAC coils accelerate rust on torsion springs and door hardware.
• Longer service drives delay response times; one-trip fixes are critical. When your property sits off an unpaved county road north of 80631, you cannot afford a technician who arrives without the right part or tool. We dispatch prepared.
• Evaporative coolers pull feedlot odors, forcing emergency conversions to sealed refrigerant systems. Older Greeley homes were built with swamp coolers that work fine mechanically but funnel raw outside air, and its smells, directly into living spaces on bad-wind days. We handle urgent cooler-to-AC conversions during summer heat waves.
• Chinook temperature swings cycle-stress heat exchangers and refrigerant systems. Greeley’s elevation at 4,658 feet produces violent warming events where temperatures rise 40-50°F in hours. That thermal shock cracks heat exchangers and pushes refrigerant pressures outside design limits.

Heating and Cooling in Greeley, 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 Greeley 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.
