Fast, Reliable Emergency & Commercial HVAC Across Tujunga
When your heat pump freezes on a 28°F night near Big Tujunga Canyon or your rooftop unit quits during a 105°F August afternoon, you need an HVAC team that knows Tujunga’s dual-season reality. We’re Crestview Heating & Air California, and we make the run to Tujunga from our San Jose base with technicians who understand what the canyon geography does to your equipment. Call us at (844) 560-6978 for emergency service or to schedule a free estimate.
Tujunga isn’t flatland San Fernando Valley. The elevation, the Santa Ana winds channeling through the canyon, and the fire-zone building requirements all create failure modes that generic HVAC advice misses. We’ve spent 19 years learning those differences.
Why Crestview Heating & Air California Is Tujunga’s Preferred Emergency & Commercial HVAC Company
Our Emergency & Commercial HVAC team has built a 4.8-star average across 250+ reviews by showing up when systems fail and fixing what others misdiagnose. In Tujunga specifically, that means recognizing when a “simple” no-heat call is actually a cracked heat exchanger from sustained sub-25°F operation, or when a compressor shutdown traces back to canyon dust packed so deep in the coils that airflow is choked to nothing.
Marcus Feldman, our owner, still serves as Service Manager. That ownership-level accountability shapes every dispatch. When you call Crestview, you’re not routed through a call center to an anonymous subcontractor. You’re talking to a company where the owner reviews job outcomes personally.
We service nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so Tujunga homeowners and commercial property managers never hear “we don’t work on that.” Your system, our specialty. From emergency calls to commercial buildouts, we’ve handled it.
Our response to Tujunga is direct. No franchise layers, no outsourced dispatch. Owner-managed, not outsourced.
Our Emergency & Commercial HVAC Services in Tujunga
24/7 Emergency HVAC
Tujunga’s temperature swings don’t keep business hours. We’ve responded to midnight heat-exchanger failures on mid-century ranches near Foothill Boulevard and compressor shutdowns at commercial properties along Commerce Avenue when Santa Ana dust choked the coils on a Sunday. Our emergency line connects you to a technician who can articulate what’s happening and what it’ll take to fix it, not just a dispatcher reading a script. If your system is down now, call (844) 560-6978.
Commercial HVAC
Tujunga’s commercial buildings — from the retail strips along Foothill Boulevard to the light industrial near the 210 corridor — face a compliance layer their Burbank counterparts often skip. Properties in LA City’s Very High Fire Hazard Severity Zone require outdoor unit siting and fresh-air intake screening that accounts for ember intrusion. We’ve navigated LADBS inspections on these requirements repeatedly. It’s routine for us, nearly unheard-of for flatland contractors.
Rooftop Unit (RTU) Service
Commercial RTUs in Tujunga sit exposed to Santa Ana winds that deposit ash and dust loads far heavier than valley-floor locations. Filter intervals shrink. Condenser coils foul faster. We factor this into maintenance schedules and emergency diagnostics, because an RTU that runs fine in Glendale often struggles here without adjusted care.
Chiller Service
While less common in Tujunga’s smaller commercial footprint, chillers serving medical or light industrial facilities face the same canyon dust infiltration and wider ambient temperature swings. Our 19 years of factory-trained experience across Carrier, Trane, and other major brands means we can service legacy chiller controls or modern variable-speed systems without the “call the manufacturer” delay.
HVAC Inspection
Given Tujunga’s fire-zone requirements and aging housing stock, inspections here carry extra weight. We check ember-screen integrity on outdoor intakes, assess ductwork condition in those 140°F attics, and document heat-exchanger condition for properties with furnaces that have run hard through real winters. An inspection from Crestview gives you specific, actionable findings — not a generic checklist.

Trusted Brands We Service in Tujunga
We stock parts and maintain factory-trained compatibility across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Tujunga customers, that translates to fewer “order and wait” scenarios. When a Lennox heat pump fails on a frosty night near Big Tujunga Canyon Road or a Goodman furnace cracks under sustained winter load, we can often source components without the multi-day delay that strands you. Your system, our specialty — and we’ve got the parts relationships to prove it.
Common Emergency & Commercial HVAC Problems We See in Tujunga Homes
- Condenser coils choked with canyon dust and Santa Ana ash. The geography here channels debris straight through residential and commercial properties alike. We’ve pulled coils so packed that airflow dropped 60% before the homeowner noticed warm air. Summer peaks finish the job, overheating compressors to shutdown.
- Heat exchanger cracks from genuine winter demand. Tujunga nights hit the mid-20s°F. Furnaces run sustained cycles their flatland cousins never face. We inspect for CO risk every time we open a furnace in this market, because cracked exchangers here aren’t theoretical.
- Original 1950s ductwork disintegrating in superheated attics. Those mid-century bungalows and ranches? Their attics bake past 140°F in July. Duct sealant cooks off. Flexible duct crumbles. The result is massive air loss, short-cycling equipment, and emergency “no cool” calls that trace back to infrastructure, not the HVAC unit itself.
- Heat pump defrost failures at higher elevations. Near the canyon, intermittent freezing temperatures stress heat pumps sized for milder SFV winters. Defrost cycles fail when coils are already compromised by dust loading. We see this pattern repeatedly on service calls above 1,500 feet.
Pricing for Emergency & Commercial HVAC in Tujunga, CA
We believe in upfront numbers. Here’s what typical Emergency & Commercial HVAC work runs in Tujunga:
| Service | Typical Range in Tujunga |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |
| Tune-Up | $80–$200 |
What moves you within these ranges? The age of your equipment, accessibility (rooftop RTUs cost more to reach than ground-level units), and whether we’re addressing a single failure point or cascading damage from deferred maintenance. That 1950s ductwork we mentioned? If it’s degraded, repair costs climb because we’re fixing the delivery system, not just the source. Emergency calls outside standard hours carry additional trip charges, which we’ll quote before we roll.
Every estimate is free. Call (844) 560-6978 for exact pricing on your specific system.

FAQs — Emergency & Commercial HVAC in Tujunga
Yes. Properties along and above Foothill Boulevard near the Big Tujunga Canyon Road corridor fall within LA City’s Very High Fire Hazard Severity Zone, and LADBS requires ember-resistant screening on fresh-air intakes and specific outdoor condenser placement. We install and inspect this screening as part of standard service in this zone. Call (844) 560-6978 to verify your property’s compliance.
Most likely, a combination of dust-clogged coils and inadequate defrost cycling. Higher elevations near the canyon see frost and intermittent freezing that flatland heat pumps aren’t sized for, and Santa Ana debris accelerates coil fouling. We responded to a late-winter call on Foothill Boulevard near Big Tujunga Canyon Road where a 20-year-old Carrier heat pump had frozen up after a frosty night — its defrost cycle failed because the outdoor coil was packed with canyon dust and ash. After a thorough coil cleaning and refrigerant charge check, we upgraded the outdoor thermostat and installed ember-resistant screening per LADBS fire-zone guidelines; the unit is now handling the dual burden of Santa Ana dust and mountain frost without issue. If yours failed similarly, we can diagnose and fix it. Call for a free estimate.
Original ductwork in Tujunga’s mid-century housing stock typically runs through unconditioned attics that exceed 140°F in summer, accelerating seal failure and material degradation. Emergency calls often reveal that the HVAC unit is functional but the delivery system is leaking 30–50% of conditioned air. Repair costs then include duct sealing or section replacement, pushing typical jobs toward the higher end of our ranges. We assess duct integrity on every call and give you repair-versus-replace guidance with real numbers.
Shorten your interval by at least 30%. The canyon geography channels Santa Ana wind events directly through Tujunga, depositing heavy dust and ash loads that clog filters and foul condenser coils far faster than flatland parts of the San Fernando Valley. Most Tujunga homeowners we serve on maintenance plans use 30-day filter checks during Santa Ana season rather than standard 90-day intervals. Call (844) 560-6978 to set up a schedule that matches your address’s exposure.
The RTU itself isn’t at higher fire risk, but its placement and intake configuration must comply with LA City fire-zone requirements for ember intrusion protection. LADBS inspectors scrutinize these details on Tujunga commercial properties in ways they don’t for flatland Burbank or Glendale jobs. We’ve passed these inspections repeatedly and build compliance into our RTU installations and retrofits from the start. For a fire-zone-compliant commercial HVAC assessment, call for a free estimate.
