Why Northstar Heating & Air San Francisco Is Van Nuys’s Preferred Emergency & Commercial HVAC Company
We’ve built our reputation in Van Nuys one emergency call at a time. 357 customers have left verified reviews, and our 4.9-star average reflects something specific to this market: we show up fast, we diagnose accurately, and we don’t hand you off to a subcontractor you’ve never met.
Daniel Okafor is the technician who answers your call and the one who shows up at your door. That matters in Van Nuys, where a no-cool emergency at a retail space on Sepulveda Boulevard or a failed rooftop unit above an apartment complex on Hazeltine Avenue can’t wait for a dispatcher to find “who’s available.” Ten years in the field means Daniel has worked on the exact equipment, duct configurations, and building types that dominate this area.
Response time to Van Nuys typically runs under 90 minutes for emergency calls placed before 6 PM. We know the local traffic patterns, which loading docks have clearance for commercial vans, and which older buildings on Kittridge Street have rooftop access that requires specific coordination. That local fluency saves hours on every job.
Our Emergency & Commercial HVAC Services in Van Nuys
24/7 Emergency HVAC
Van Nuys doesn’t cool down at night. The Valley’s geography — ringed by the Santa Monica, Santa Susana, and San Gabriel mountain ranges — traps heat and blocks marine air flow that moderates temperatures even in nearby Burbank. Santa Ana wind events push hot, dry desert air directly through the Valley floor, creating back-to-back high-demand nights that stress cooling equipment with no overnight recovery. When your system fails at 10 PM on a 95°F night, we answer. Emergency HVAC repair in Van Nuys typically runs $175–$765 for AC systems and $175–$825 for heating, with after-hours calls billed at standard emergency rates — no surprise multipliers.
Commercial HVAC
Van Nuys’s commercial base runs heavy on light industrial, medical offices, retail strip centers, and mid-size apartment complexes — many housed in 1960s–1980s buildings with original rooftop infrastructure. We handle package units, split systems, and zoned controls for businesses along Van Nuys Boulevard and Sherman Way. A decade of doing this right means we’ve serviced Lennox, Trane, and Goodman commercial systems common to this era of Valley construction. We also handle AC Repair & Installation in Van Nuys for commercial properties upgrading from aging central systems.
Rooftop Unit Service
Rooftop units are the workhorses of Van Nuys commercial real estate, and they’re exposed to brutal conditions. Summer attic temperatures in low-pitched Valley roofs routinely hit 140–160°F, and rooftop units absorb that radiated heat plus direct sun. We see compressor failures, refrigerant leaks, and economizer malfunctions accelerated by this thermal load. Daniel personally inspects curb integrity, coil condition, and belt tension — the maintenance items that prevent catastrophic failure during peak season. Annual maintenance contracts for Van Nuys rooftop units start at $95–$235 per visit.
Chiller Service
Medical offices and light industrial facilities in Van Nuys rely on chillers for precise climate control. We’ve serviced Carrier and Rheem chiller systems in Valley medical plazas where temperature stability isn’t negotiable. Chiller repair requires brand-specific expertise — our certification across 9 major brands means no referral runarounds when your system needs immediate attention. We stock common chiller components locally to minimize downtime for Van Nuys businesses.
Annual Maintenance & HVAC Inspection
Given Van Nuys’s thermal extremes, annual maintenance isn’t preventive — it’s survival. Our tune-ups run $95–$235 and include coil cleaning, refrigerant level verification, duct pressure testing, and electrical connection inspection. For commercial clients, we schedule around your operations, including early-morning or weekend slots to avoid disrupting business hours.

Trusted Brands We Service in Van Nuys
Northstar is certified to work on 9 major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — which means 9 major brands, one company, no mismatches. We maintain local parts inventory for Trane, Lennox, Goodman, and Rheem systems, the four brands we encounter most frequently in Van Nuys’s postwar housing stock and 1970s–1980s commercial buildings. That inventory translates to faster repairs and fewer return trips. Whether it’s an emergency call or a full system install, you won’t wait days for a part to ship from a regional warehouse.
Common Emergency & Commercial HVAC Problems We See in Van Nuys Homes
- Attic duct collapse in 1950s ranch homes. The bulk of Van Nuys housing is postwar tract development with low-pitched roofs that superheat to 140–160°F. Original R-4 flex duct sags off hangers, cracks, or disconnects entirely. A tech familiar with Van Nuys checks attic runs first on any no-cool call — the supply air gains 10–15°F before hitting a register, and no refrigerant charge adjustment fixes that.
- Compressor failure from continuous high-load operation. Equipment that would last 18 years in Santa Monica may burn out in 10–12 in Van Nuys. Systems here run harder, longer, with fewer recovery cycles. We see premature compressor deaths every July and August.
- Clogged condensate lines in older apartment complexes. Two-story Valley apartment buildings from the 1960s often have original drain configurations that back up during Santa Ana wind events, when dust and debris load increases dramatically.
- Rooftop unit belt and bearing failure on commercial buildings. Thermal cycling between 115°F days and 70°F nights stresses rubber and metal components. We catch these during maintenance; without it, they fail during peak demand.

What moves you within these ranges? System age, accessibility, and parts availability. A failed compressor on a 20-year-old Goodman rooftop unit costs more than a capacitator swap on a five-year-old Trane split system. Commercial properties with limited roof access or after-hours security requirements add time. We quote upfront before any work begins — no open-ended billing, no “we’ll see how it goes.” Free estimates are standard for installations and major replacements. Call (855) 600-3322 for your exact quote.

FAQs — Emergency & Commercial HVAC in Van Nuys
We typically arrive within 90 minutes for emergency calls placed before 6 PM anywhere in Van Nuys, including the 91470, 91482, 91496, and 91499 ZIP codes. After 6 PM and on weekends, response time extends to 2–3 hours depending on call volume. Call (855) 600-3322 — we’ll give you a real ETA, not a placeholder.
We service the full Van Nuys area, from the postwar ranch neighborhoods near Victory Boulevard and Kittridge Street to the commercial corridors along Van Nuys Boulevard and Sepulveda. Daniel Okafor has personally worked on systems in each of these areas and understands the specific building stock and access challenges.
Our emergency rates are consistent across our service area — we don’t surcharge for Van Nuys specifically. That said, repair costs here often run toward the higher end of our ranges because systems work harder and fail more severely. A compressor that seizes after running 16 hours straight in 110°F heat usually needs full replacement, not repair. We quote your specific situation before starting work.
Yes. All repairs carry a workmanship warranty, and parts are covered by manufacturer warranty where applicable. Because we’re certified on 9 major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — we can honor manufacturer warranties without routing you through a third party. 357 customers agree: accountability matters.
Replace if your system is over 12 years old, uses R-22 refrigerant, or has required more than two major repairs in three years. Van Nuys’s thermal stress ages equipment faster than coastal markets, so the standard 15–20 year lifespan doesn’t apply here. Repair if the system is under 10 years, the failure is isolated, and efficiency has been acceptable. Daniel personally evaluates this tradeoff with you — no pressure toward the more expensive option. Call (855) 600-3322 for a free assessment.
