Fast, Reliable Emergency & Commercial HVAC Across Upland
When your HVAC system fails at midnight in Upland or your commercial rooftop unit quits during a 105°F July afternoon, you need someone who shows up ready to fix it — not a dispatcher reading from a script. We’re Crestview Heating & Air California, and our Emergency & Commercial HVAC team has been serving the Inland Empire for nearly two decades. Owner Marcus Feldman still manages every job as Service Manager, so the accountability you get is ownership-level, not outsourced to a revolving door of technicians.
Upland’s unique position at the base of the San Gabriel Mountains creates HVAC challenges you won’t find in flatter neighboring cities. Cold air drains nightly out of Cucamonga Canyon, dropping winter lows near freezing in northern Upland’s 91784 ZIP while southern 91786 bakes through triple-digit summers. That dual-season load wears equipment harder here. We know because we’ve repaired systems across every Upland neighborhood, from the ranch-style tracts south of Foothill Boulevard to the custom foothills homes near Cable Airport. Call (844) 560-6978 — we’ll diagnose your system and give you upfront numbers before any work starts.
Why Crestview Heating & Air California Is Upland’s Preferred Emergency & Commercial HVAC Company
Our reputation in Upland was built one repair at a time. We’ve got 250+ customer reviews averaging 4.8 stars, and many of those come from Upland homeowners and commercial property managers who called us back a second and third time because the job held up. That matters in a city where Santa Ana winds can test your ductwork within days of a service call.
Marcus Feldman doesn’t just own Crestview — he’s our Service Manager, actively running jobs in the field. When you call, you’re getting 19 years of hands-on HVAC experience directed at your specific system, not a franchise playbook. We’ve worked on Carrier, Trane, Lennox, Goodman, Rheem, and five other major brands, so “we don’t service that” isn’t in our vocabulary.
Our response time to Upland is built around knowing the territory. We understand that a call from northern Upland near the canyon mouth might involve a frozen heat pump on a 28°F night, while a downtown Upland commercial building on Central Avenue needs a rooftop unit back online before the next business day. Both get priority. Both get Marcus’s direct oversight.
Our Emergency & Commercial HVAC Services in Upland
24/7 Emergency HVAC
HVAC failures don’t wait for business hours, and in Upland’s climate extremes, neither can you. A dead furnace in 91784 during a January cold drain can mean frozen pipes. A failed AC in 91786 during August heat is a genuine health risk for vulnerable residents. Our emergency line connects you to Marcus directly — no call center, no ticket queue. We carry parts for Trane, Lennox, Goodman, and Rheem systems so most Upland emergency calls resolve in a single trip. That’s not a slogan; it’s how we’ve kept our 4.8-star rating across 250+ reviews.

Commercial HVAC
Upland’s commercial corridor along Foothill Boulevard and the business parks near the 210 freeway depend on reliable climate control. We’ve serviced retail spaces, medical offices, and light industrial buildings throughout the city. Commercial systems in Upland face the same dual-season stress as residential — summer peaks over 105°F, winter nights driven cold by canyon drainage — but with higher occupancy loads and more complex zoning. Our factory training across nine major brands means we won’t tell you to replace a viable system just because we don’t know how to repair it.

Rooftop Unit Service
Rooftop units are common on Upland’s commercial buildings, from the strip developments along Mountain Avenue to the professional offices near Euclid Avenue. These packaged systems take the worst of Inland Empire sun exposure plus the debris load from Santa Ana wind events. We’ve found RTU compressors failed from summer overwork, economizer dampers stuck open from dust intrusion, and control boards damaged by heat cycling. Marcus inspects these systems personally — he knows that a 20-ton unit serving a downtown Upland medical plaza can’t wait for a parts order from out of state.

Chiller Service
While less common in Upland’s smaller commercial buildings, chillers serve several larger properties and institutional clients in the area. Chiller failures during peak cooling season can shut down entire facilities. Our 19 years of experience includes chiller diagnostics, refrigerant management, and controls troubleshooting. We coordinate with Upland’s commercial clients to minimize downtime, because lost climate control means lost productivity.

Trusted Brands We Service in Upland
Your system, our specialty — that’s not marketing, it’s inventory strategy. We stock parts and have factory-level familiarity with Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Upland customers, this means faster turnaround on repairs and no pressure to replace equipment just because the brand isn’t in our comfort zone. We’ve repaired 30-year-old Rheem furnaces in 91786 ranch homes and installed Daikin mini-splits in 91784 foothills additions where zoning was never part of the original design. When Santa Ana winds hit and your Lennox rooftop unit throws a fault code, we know what that code means and we carry the components to fix it.
Common Emergency & Commercial HVAC Problems We See in Upland Homes
- Duct separation from negative attic pressure during Santa Ana winds. The Cucamonga Canyon gap funnels powerful wind events straight into northern Upland. We’ve found flex-duct joints pulled completely apart in attics near the canyon mouth, dumping conditioned air into insulation and pulling hot attic air into living spaces. We responded to a ranch-style home in central Upland (91786) where the original 1970s ductwork had separated at a flex-duct joint after exactly this scenario. Reconnecting the joint and installing a heavy-duty filter resolved the airflow issue, but we also upsized the undersized air handler to handle the home’s 105°F summer demand in one trip.
- Compressor failure from undersized air handlers in aging ranch homes. The 1950s–1970s tract housing that dominates southern Upland often has original or first-replacement equipment sized for milder design temperatures. When a 105°F day hits, an undersized air handler can’t move enough air across the evaporator coil. Liquid floodback damages the compressor. We’ve replaced dozens of these in Upland — and properly sized the replacement so it doesn’t happen again.
- Heat pump defrost failures in northern Upland foothills. The cold air drainage from Cucamonga Canyon pushes winter lows in 91784 well below what heat pumps in flatter Inland Empire cities experience. Defrost controls that work fine in Ontario or Montclair can ice up completely in northern Upland, leaving the backup heat strips to carry the full load at maximum cost.
- Clogged coils and failed filters post-wind event. Santa Ana winds don’t just move air — they move dust, pollen, and debris from the canyon and desert beyond. We’ve pulled filters loaded to near-failure in days, not months, and found condenser coils choked enough to trip high-pressure switches. Northern Upland properties see this pattern repeatedly; we build heavier filtration into our recommendations there.
Pricing for Emergency & Commercial HVAC in Upland, CA
We don’t quote blind, and we don’t bait-and-switch. Here’s what typical Emergency & Commercial HVAC work runs in Upland’s market:
| Service | Typical Range in Upland |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| Tune-Up | $80–$200 |
What moves you within these ranges? System age, accessibility, and whether parts need emergency sourcing. A compressor replacement on a 20-year-old Goodman in a tight Upland attic hits the high end. A failed capacitor on a five-year-old Trane with clear service access sits at the low end. Emergency calls outside standard hours carry additional trip charges — we’ll tell you exactly what before we roll. Every estimate is free, and we don’t start work until you approve the number. Call (844) 560-6978 for your exact quote.
We Also Serve Cities Near Upland
Our service radius extends throughout the western Inland Empire. We regularly handle emergency and commercial calls in Claremont, Montclair, Rancho Cucamonga, and Ontario — though Upland’s canyon-adjacent climate patterns keep us busiest here. Each city has its own HVAC personality; Ontario’s flatter terrain doesn’t see the winter cold drainage we fight in northern Upland, and Claremont’s hillside homes present different access challenges than Upland’s central ranch tracts. Wherever you are, Marcus manages the job personally.

FAQs — Emergency & Commercial HVAC in Upland
They face a dual-season load profile rare in the Inland Empire. Winter nights in 91784 dip near freezing from cold air drainage, while summer still hits 100°F+, so equipment must handle genuine heating and cooling extremes. Homes in central and southern Upland (91786) deal primarily with summer peaks. We size systems for the actual load, not a regional average. Call (844) 560-6978 and we’ll calculate your specific requirements — estimates are free.
We focus on HVAC systems, not garage doors. For commercial-grade opener issues on oversized or heavy-duty doors, you’ll want a dedicated garage door specialist with experience in high-cycle spring and motor combinations. We’re happy to refer trusted local contractors we’ve worked alongside. For your heating and cooling needs on that same acreage property, we’re the right call — call (844) 560-6978.
We see a concentrated wave of calls after every significant Santa Ana event, typically 3–5 times per fall and winter season. Northern Upland near the canyon gap is most affected — flex-duct separations and filter overloads are the two most common issues. If your home is in 91784 and you haven’t had your attic ductwork inspected recently, it’s worth scheduling before the next wind event. Call (844) 560-6978 for a tune-up at $80–$200.
Yes. We’ve serviced rooftop units up to and above 20 tons for Upland commercial clients, including properties along Central Avenue and near the Foothill corridor. Marcus carries the diagnostic tools and common parts for major RTU brands, and our supplier relationships cover same-day sourcing for less common components. For a 20-ton emergency, we’ll assess on arrival and give you a repair-or-replace recommendation with real numbers. Call (844) 560-6978 — we’ll prioritize commercial downtime.
All nine major brands in our factory-training portfolio: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We don’t turn away commercial emergencies because of brand. Our parts inventory emphasizes Trane, Lennox, Goodman, and Rheem as the most common in Upland’s installed base, but we can source for any of the nine within emergency timelines. Call (844) 560-6978 with your unit model — we’ll confirm parts availability before we roll.
