Fast, Reliable Emergency & Commercial HVAC Across Altadena
When your furnace quits during a Santa Ana wind event or your rooftop unit fails at your Altadena commercial property, you need an HVAC company that knows this hillside community, not a dispatch center routing calls from Burbank. We’re Crestview Heating & Air California, and our Emergency & Commercial HVAC team responds to Altadena calls with the urgency that 100°F summer days and fire-season air quality demand. From the Craftsman bungalows along Altadena Drive to the mid-century ranches in the upper foothills near Loma Alta Park, we’ve worked on the specific heating and cooling challenges this unincorporated community presents. Call us at (844) 560-6978 for same-day emergency service and free estimates on any commercial or residential system.
Why Crestview Heating & Air California Is Altadena’s Preferred Emergency & Commercial HVAC Company
Our reputation in Altadena was built one emergency call at a time, especially through the brutal 2024-2025 winter when the Eaton Fire tested every contractor’s availability and integrity. We’ve earned a 4.8-star average across 250+ customer reviews, and many of those come from Altadena homeowners who needed honest guidance on whether smoke-damaged systems could be salvaged or required full replacement.
Here’s what separates us from competitors who advertise “Pasadena service” but barely know where Altadena’s city limits end (hint: there aren’t any, since Altadena isn’t incorporated). Owner Marcus Feldman serves as our active Service Manager, meaning the person answering your technical questions and overseeing your job has 19 years of hands-on HVAC experience and personal accountability for the outcome. We’re not a franchise sending whichever technician is available. We’re owner-managed, not outsourced.
Our response time to Altadena averages same-day for emergency calls, and we stock parts for Trane, Lennox, Goodman, and Rheem systems so we’re not ordering components from a warehouse two counties away while your employees sweat or your tenants freeze. We also understand that Altadena’s permit process runs through LA County Building & Safety, not Pasadena’s municipal department, and we navigate that difference routinely so you don’t face delays.
Our Emergency & Commercial HVAC Services in Altadena
24/7 Emergency HVAC
Altadena’s elevation and exposure to Santa Ana winds create genuine emergency scenarios: furnaces overworked during cold snaps, AC compressors failing under debris-clogged coils, and post-Eaton Fire systems contaminated by smoke damage that wasn’t immediately visible. Our emergency line connects you directly to a technician who can assess whether you’re facing a same-day repair or a safety-critical shutdown. We don’t charge premium rates just for answering after hours, and we’ll tell you honestly if a temporary fix can hold until morning or if your heat exchanger crack requires immediate replacement.
Commercial HVAC
Altadena’s commercial corridor along Lake Avenue and the professional offices near the Altadena Golf Course depend on reliable climate control for staff productivity and client comfort. We service packaged rooftop units, split systems, and light commercial configurations for small-to-mid-size properties. Because Altadena sits in LA County’s Very High Fire Hazard Severity Zone, commercial installations here face stricter combustion-air and filtration requirements than equivalent jobs in Pasadena, and we spec accordingly. From emergency calls to commercial buildouts, your system is our specialty.
Rooftop Unit Service
Altadena’s commercial rooftops take a beating. Santa Ana winds deposit fine debris and ember particles that clog condenser fins and corrode electrical connections. The January 2025 Eaton Fire added ash and smoke residue to that loading. We clean, test, and repair Carrier, Trane, and Rheem rooftop units with factory-trained procedures, and we inspect fire-season damage that less experienced contractors might miss. Upper Altadena properties near the mountain face get particular attention to intake placement, since poorly positioned return-air openings can draw contaminated air directly into your building’s circulation.
HVAC Inspection
Before you buy an Altadena property or reactivate a system after the Eaton Fire, a thorough inspection protects you from hidden costs. We examine ductwork for smoke infiltration, test heat exchangers for cracks common in decades-old furnaces, and verify that equipment sizing matches Altadena’s cooler foothill microclimate rather than valley-floor assumptions. Our inspection reports include specific repair priorities and replacement timelines, not vague “monitor” recommendations. For commercial clients, we document compliance with LA County fire-safety requirements that affect HVAC intake and filtration specifications.

Trusted Brands We Service in Altadena
Your system, our specialty. We maintain factory-trained compatibility across nine major brands, and for Altadena customers, we keep common parts in stock for Trane, Lennox, Goodman, and Rheem systems, the brands we encounter most frequently in this area’s older housing stock and light commercial buildings. That local inventory means faster turnaround when your 1980s Goodman furnace fails on a January night or your commercial Trane rooftop unit throws an error code during business hours. We don’t tell you “we don’t work on that.” We’ve spent 19 years ensuring we work on virtually everything.
Common Emergency & Commercial HVAC Problems We See in Altadena Homes
- Smoke-damaged ductwork from the Eaton Fire contaminates indoor air when systems are reactivated after months of disuse. We see homeowners in the 91001 and 91003 ZIP codes who assume their ducts survived because the structure did, only to find ash residue and acrid odors circulating through every room. Professional cleaning or replacement is the only safe remedy.
- Original cellulose insulation in pre-1960 attics shifts or sags over decades, blocking newly routed duct chases and causing airflow restrictions that strain blowers and create hot spots. In Altadena’s tight Craftsman attics, this is a near-universal issue during retrofit work.
- Santa Ana winds load outdoor condenser coils with debris and embers, leading to overheating failures and fire risk if not cleaned promptly. We responded to an emergency call on a Craftsman bungalow on Altadena Drive where a legacy Rheem furnace from 1968 failed mid-heating during a Santa Ana event. The heat exchanger had cracked from decades of use, and the return-air intake was drawing ash from the nearby Eaton Fire zone. We recommended a full replacement with a sealed-combustion Carrier unit and a MERV-13 filter cabinet, re-routing the intake away from prevailing up-canyon winds.
- Fire-hardened reinstalls require upgraded filtration that older systems cannot accommodate. Post-Eaton Fire, many Altadena replacement jobs are being spec’d with MERV-13 or better filtration and dedicated smoke-mode controls as baseline requirements, not optional upgrades. Existing ductwork and blower capacity often cannot handle that load without modification.
Pricing for Emergency & Commercial HVAC in Altadena, CA
We believe in upfront pricing, especially after a disaster like the Eaton Fire when homeowners are already navigating insurance claims and contractor uncertainty. Here’s what typical services run in Altadena’s market:
| Service | Price Range in Altadena |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |
| Tune-Up | $80–$200 |
Several factors push Altadena jobs toward the higher end of these ranges. The unincorporated status means LA County permit fees and inspection scheduling differ from Pasadena municipal rates. Post-fire replacements often require duct cleaning or replacement, fire-resistant intake relocation, and upgraded filtration that adds material cost. And the tight attics in pre-1960 homes demand more labor for duct routing than open-construction modern builds. We discuss all of this before any work begins, and estimates are always free. Call (844) 560-6978 for your specific quote.

FAQs — Emergency & Commercial HVAC in Altadena
Yes, and because Altadena is unincorporated LA County, your permit goes through LA County Building & Safety, not Pasadena’s city department. We handle the application and inspection scheduling as part of our installation service, so you don’t navigate the county system alone. Call (844) 560-6978 and we’ll walk you through the timeline for your specific job.
MERV-13 or better is now the practical minimum for Altadena homes in the Eaton Fire impact zone, and many replacement systems we’re installing include dedicated smoke-mode controls. Standard MERV-8 filters will not capture the fine ash and particulate that infiltrated ductwork during the fire. We assess your existing blower capacity before recommending upgrades, since higher filtration adds airflow resistance that older systems may not handle.
They present specific challenges: tight attics with original cellulose insulation, no existing duct chases, and structural elements that limit equipment placement. We’ve completed dozens of these retrofits in Altadena, and our approach preserves architectural integrity while achieving modern comfort and fire-safety standards. The key is custom duct design, not forcing standard layouts into non-standard spaces.
Altadena’s 1,000–1,500 foot elevation runs several degrees cooler than the San Gabriel Valley floor, especially overnight, but still experiences extreme summer heat events. Equipment sized to Pasadena valley specs will be miscalculated for upper foothill lots. We perform Manual J load calculations using Altadena-specific design temperatures, not generic LA County data, to avoid oversized short-cycling or undersized struggling.
Yes, we maintain and repair commercial rooftop units throughout Altadena’s commercial areas, with particular attention to Santa Ana debris loading and post-fire intake safety. Our factory training covers Carrier, Trane, Rheem, and other major commercial brands. For emergency rooftop failures, our same-day response applies. Call (844) 560-6978 for immediate service or to schedule preventive maintenance before the next wind event.
