Fast, Reliable Emergency & Commercial HVAC Across Tujunga
When your furnace dies on a 38°F January night in Tujunga or your rooftop AC quits during a Santa Ana heat spike, you need a technician who knows this canyon, not a dispatcher sending someone from Reseda. Daniel Okafor, owner and lead technician at Northstar Heating & Air, personally handles emergency and commercial HVAC calls throughout the 91042 and 91043 ZIP codes, typically arriving within 45–60 minutes for urgent issues. We’ve spent a decade working on the specific systems found in Tujunga’s post-war hillside homes and the small commercial buildings along Foothill Boulevard, so we don’t waste time figuring out your setup. Call (855) 600-3322 for immediate response.
Why Northstar Heating & Air San Francisco Is Tujunga’s Preferred Emergency & Commercial HVAC Company
Our Emergency & Commercial HVAC team has built a 4.9-star reputation across 357 verified reviews by showing up personally and fixing things right the first time. In Tujunga specifically, customers mention the same thing repeatedly: Daniel arrives, diagnoses the actual problem, and doesn’t push equipment you don’t need. That’s what happens when the owner is also the lead technician — there’s no commission-driven upsell, no rotating crew of strangers, just one expert whose name is on every invoice.
Response time to Tujunga averages under an hour for true emergencies, faster than most valley-based outfits because we know the canyon road network and don’t get hung up at the 210 Freeway interchange during rush. We’ve replaced compressors on Pinewood Avenue at 10 PM, restored heat to a daycare on Commerce Avenue before opening, and cleared ash-clogged condensers along Big Tujunga Canyon Road after Santa Ana wind events that valley technicians rarely encounter.
Our familiarity with Tujunga’s local conditions runs deep. We know which hillside homes on the north slope freeze first, which commercial strips along Foothill have aging packaged units from the 1990s, and how the LADBS ember-resistant vent requirements for the Very High Fire Hazard Severity Zone affect every installation, Air Quality & Ventilation — Tujunga project, and major duct replacement in this area. Out-of-area contractors routinely miss the 1/16-inch mesh screening requirement on attic and foundation vents; we build it into every quote because we’ve seen plan checkers flag it on 91042 permits enough times to know better.
Our Emergency & Commercial HVAC Services in Tujunga
24/7 Emergency HVAC Repair
Furnace failures at 2 AM. AC compressors seized on 105°F Santa Ana afternoons. Refrigerant leaks that turn your restaurant kitchen into a sauna before dinner service. Daniel answers emergency calls directly — no phone tree, no third-party answering service — and carries common parts for Goodman, Rheem, and York systems to restore heating or cooling on the first trip. In Tujunga’s elevation-driven temperature swings, where winter nights can drop 10°F below the valley floor, a dead furnace isn’t uncomfortable; it’s dangerous for elderly residents or infants.
Commercial HVAC Service & Repair
Small-to-mid-size businesses along Foothill Boulevard and Commerce Avenue depend on consistent climate control for customer comfort, inventory protection, and employee productivity. We service packaged rooftop units, split systems, and Heat Pump & Mini Split — Tujunga solutions for retail spaces, medical offices, restaurants, and light industrial operations throughout Tujunga. Our 10 years of commercial experience means we understand how to minimize disruption — we work around your hours, coordinate with property managers, and document everything for lease compliance or insurance claims.
Rooftop Unit (RTU) Installation & Repair
Tujunga’s commercial buildings, particularly the single-story retail strips built between the 1960s and 1980s, rely heavily on packaged rooftop units that sit exposed to the canyon’s punishing conditions. Santa Ana winds don’t just clog coils with debris; we’ve seen unsecured RTU panels blown loose and units physically shifted on their curbs. Daniel personally inspects structural integrity, curb condition, and wind restraint on every rooftop call. When replacement is necessary, we size units correctly for Tujunga’s actual heating and cooling loads — not valley-floor assumptions — which often means higher heating capacity and robust defrost cycles than flatland LA specs would suggest.
Chiller Service & Repair
While less common in Tujunga’s smaller commercial footprint, chillers serve several medical and light industrial facilities in the area where precise temperature control matters. We handle chiller diagnostics, refrigerant management, compressor repair, and control calibration for systems serving critical environments. Given Tujunga’s wide temperature range and the extended shoulder seasons at 1,500–2,000 feet elevation, chiller systems here work harder and longer than in coastal zones, accelerating wear on compressors and heat exchangers.

Trusted Brands We Service in Tujunga
We maintain direct experience on nine major HVAC brands — Carrier, Trane, Lennox in Tujunga, Goodman, Rheem, York, Daikin, Bryant, and American Standard — which means no referral runarounds when your system needs specialized attention. For Tujunga customers, this translates to faster repairs because Daniel stocks common Goodman, Rheem, and York components locally and can source Daikin mini-split parts without the multi-day delays that plague less-prepared outfits. Whether it’s an emergency call or a full system install, you’re dealing with one technician who knows your brand’s quirks, not a dispatcher guessing which subcontractor might handle it.
Common Emergency & Commercial HVAC Problems We See in Tujunga Homes
- Gravity furnace failures in post-war homes. Many Tujunga houses built in the 1950s still run original wall furnaces or gravity floor furnaces. These units lack forced-air distribution, heat unevenly, and develop cracked heat exchangers after 40+ years of thermal cycling. We evaluate whether repair or conversion to a ducted system makes sense given your home’s layout.
- Ash and debris clogging from Santa Ana wind events. The Big Tujunga Canyon funnels dry, high-velocity winds that pack condenser coils with wildfire ash, dust, and vegetative debris. This restricts airflow, spikes head pressure, and causes compressor overheating — a failure mode valley-floor technicians rarely see.
- Deteriorated flex duct in small attics. Retrofitting central HVAC into Tujunga’s low-pitch, compact attic spaces often reveals original flex ductwork that has degraded from decades of temperature swings. We find collapsed sections, disconnected runs, and rodent damage that explain why certain rooms never reach set temperature.
- Undersized heating for hillside exposure. North-facing homes on the canyon slopes experience significantly more heating load than south-facing units on the same street. We’ve replaced systems that were properly sized by valley standards but chronically unable to maintain 68°F on clear January nights when radiational cooling drops temperatures fast at this elevation.
Pricing for Emergency & Commercial HVAC in Tujunga, CA
We believe in upfront numbers, not surprise invoices. Based on our work across the San Francisco market and Tujunga’s specific conditions, here’s what you can expect:
| Service | Typical Range in Tujunga |
|---|---|

Every estimate is free, and we accept calls at (855) 600-3322 for exact pricing on your specific system.

Base repair and installation rates are consistent across our service area, but Tujunga jobs sometimes carry modest additional costs for two specific reasons: ember-resistant vent screening required by LADBS in the Very High Fire Hazard Severity Zone, and the extra labor time hillside access and compact attics can add to installation work. We disclose these factors in your free estimate before any work begins. For an exact quote on your specific job, call (855) 600-3322 — estimates are always free.
We stand behind our work with a satisfaction guarantee on all repairs and installations. Specific warranty terms vary by equipment type and manufacturer — new Daikin and Rheem installations carry full manufacturer warranties that we register and manage for you, while repair warranties cover parts and labor for a period we specify on your invoice. Daniel explains warranty details in plain language before you commit, and he’s the same person who honors them if issues arise. For warranty specifics on your system, call (855) 600-3322.
