The equipment age is different. The urgency is always the same. Our technicians carry parts for nine major brands, put on shoe covers without being asked, and treat your property the way they would their own mother’s. That is how we have operated since 2018.

Our Emergency & Commercial HVAC Services in Tempe
24/7 Emergency HVAC
Tempe’s urban heat island keeps nighttime lows above 90°F for weeks at a stretch. Your compressor never gets a break. When it fails at midnight on a Saturday, you need a company that answers the phone. We do. Our emergency crew carries diagnostic tools and replacement parts for compressor failures, refrigerant leaks, blower motor burnout, and electrical panel issues. We have responded to calls from the student-rental corridors near University Drive, from the townhome clusters south of Broadway, and from commercial kitchens along Mill Avenue that cannot afford an hour without ventilation.
Commercial HVAC
Tempe’s commercial base runs from ASU campus buildings to retail along Southern Avenue to light industrial near the airport corridor. Each has different load profiles, occupancy schedules, and code requirements. We service packaged rooftop units, split systems, and dedicated outdoor air systems for restaurants, medical offices, property management groups, and small retail. We know Maricopa County permitting and work with building engineers to minimize tenant disruption. Our commercial clients in Tempe get the same upfront pricing and 90-Day Done Right Promise as our residential customers.
Rooftop Unit (RTU) Service
Rooftop units dominate Tempe’s commercial and multi-family landscape, especially in the 85281 and 85282 corridors where 1960s and 1970s garden apartments were built flat-roofed and dense. These units bake in 150°F attic-adjacent temperatures and inhale cottonwood seed, monsoon dust, and urban particulate. A packed condenser coil in August will trip a high-pressure lockout within days. We clean, repair, and replace RTUs from all major manufacturers, and we carry the safety switches and hard-start kits that keep marginal units running through the worst heat.
Chiller Service
While less common in small commercial, chillers serve several larger Tempe properties including ASU-adjacent research facilities and medical office buildings. We handle chiller diagnostics, refrigerant management, cooling tower maintenance, and controls calibration. Chiller downtime in August is not an inconvenience. It is an operational emergency. We treat it that way.

Trusted Brands We Service in Tempe
We are trained to service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our Tempe warehouse stocks common compressors, contactors, capacitors, and blower motors for the brands most frequently found in this market. That means faster turnaround for you. A York rooftop unit at a commercial property near Priest Drive does not wait for a parts order from out of state. We get it running with what we have on the truck or what we can pull same-day from our local inventory.
Common Emergency & Commercial HVAC Problems We See in Tempe Homes
- Compressor failure in aging R-22 systems. North Tempe’s student-rental housing stock is full of 1960s and 1970s equipment still running R-22. Absentee landlords defer maintenance until August forces the issue. The compressor seizes. We replace it or recommend a full system conversion.
- Condenser coils packed with monsoon dust and cottonwood seed. Units near Tempe Town Lake and the ASU campus accumulate debris faster than anywhere else in the metro. A coil that looks fine in May can be completely blocked by mid-July. We clean them properly, not with a garden hose.
- Deteriorated flex ductwork in attic spaces. Attic temperatures in older Tempe complexes exceed 150°F. Original flex duct cracks, separates at connections, and leaks conditioned air into the roof cavity. The system runs constantly. The evaporator coil freezes. The tenant calls at 10 p.m.
- High-pressure lockouts after haboob events. Sudden dust storms pack condenser fins with fine caliche dust that does not rinse off easily. The unit trips on high head pressure. We deep-clean, check refrigerant charge, and install protective screening where appropriate.

The Tempe August Surge: What Property Managers Need to Know
Here is something that does not happen in Mesa, Chandler, or Scottsdale. Every August, Arizona State University’s fall move-in week collides with the absolute peak of Sonoran Desert heat, triggering a surge of emergency HVAC calls that is unique to Tempe. North of campus, in ZIP codes 85281 and 85282, absentee landlords who deferred spring maintenance now face tenant move-ins with dead compressors, leaking coils, and ductwork that has not been inspected in years.
During last August’s move-in week, our crew responded to a rooftop RTU failure at a 1970s garden-style complex near Apache Boulevard in 85281. The 10-ton Carrier unit had locked out on high pressure because monsoon dust and cottonwood seeds had packed the condenser coil solid, compounded by a failed R-22 compressor. We replaced the compressor, installed a high-pressure safety switch, and deep-cleaned the coil to restore cooling just as the first tenants arrived.
This is not a hypothetical scenario. It happens every year. Property managers who schedule pre-season inspections in June avoid the August scramble. Those who wait pay emergency rates and risk tenant turnover. We run $89 seasonal tune-ups that catch these failures before move-in week. The math is straightforward.
We Also Serve Cities Near Tempe
Our service area extends to Tempe Junction, Ahwatukee Foothills, Central City, and Chandler. If you manage properties across multiple municipalities, one call covers your portfolio. We know the jurisdictional differences in permitting and the varying housing stock from the dense student rentals of central Tempe to the suburban systems of Chandler. Same live-answer phones. Same upfront pricing. Same 90-Day Done Right Promise.

FAQs - Emergency & Commercial HVAC in Tempe
ASU’s fall move-in week overlaps with the hottest period of the Sonoran Desert summer, creating a unique demand surge in ZIP codes 85281 and 85282. Absentee landlords in the student-rental market often defer maintenance until tenant complaints force action, concentrating months of deferred problems into a single week. We add crew capacity every August specifically for this pattern. Call (866) 561-3358 to schedule pre-season maintenance and avoid the rush.
Twice per season is the practical standard for units in the 85281 corridor and near the lake, not the once-a-year baseline that works in cleaner environments. Cottonwood seed, dust, and urban particulate accumulate faster here, and a packed coil in 115°F heat will trip a high-pressure lockout within days of a monsoon dust event. Our $89 tune-up includes coil cleaning and inspection. For commercial properties with rooftop units, we offer quarterly maintenance agreements.
Yes. We repair and recharge R-22 systems, though we also provide straight talk about repair-versus-replace when the compressor fails or coils leak. R-22 refrigerant is no longer manufactured, so reclaimed supplies carry premium pricing. For property managers with multiple aging units, we can phase replacement to spread capital costs across budget years. Call for a free second opinion on any replacement quote.
We provide 24/7 emergency repair for rooftop units, chillers, split systems, and ventilation equipment, with live phone answering every hour of every day. Our commercial trucks carry parts for Carrier, Trane, Lennox, York, Daikin, and Bryant systems commonly found in Tempe’s commercial buildings. Most commercial emergency calls in Tempe are resolved in a single visit. Call (866) 561-3358 for immediate dispatch.
Yes. The combination of sudden humidity spikes and haboob dust storms creates unique stress on Tempe’s commercial systems. Dust packs condenser coils and clogs economizer screens. Humidity spikes force dehumidification loads that older controls may not handle well. Rooftop units near the Salt River corridor and Tempe Town Lake see heavier debris loading than inland Mesa or Chandler locations. We adjust our maintenance protocols for this: pre-monsoon coil inspection, post-storm verification, and protective screening recommendations where appropriate.
Fireside Heating & Air Co. has kept Tempe homes and businesses comfortable through 42 years of desert summers. We answer the phone at 2 a.m. We quote prices we stand behind. We put it in writing.
