Fast, Reliable Emergency & Commercial HVAC Across Van Nuys

Call (844) 875-9451 and we’ll get a technician moving.
Why Redwood Heating & Air San Diego Is Van Nuys’s Preferred Emergency & Commercial HVAC Company
Gregory Hahn founded this company and still leads every technical decision. That means when you call us for a no-cool emergency on a 1960s tract home near Victory Boulevard, you’re getting a Master Technician’s judgment, not a dispatcher reading from a script. Our 428 verified reviews averaging 4.6 stars include plenty from Van Nuys property managers who learned the hard way that one-brand-only dealers can’t diagnose what they weren’t trained to sell.
We’re typically on-site in Van Nuys within 90 minutes for emergency calls, and we carry parts for Carrier, Trane, Bryant, and American Standard systems so we’re not ordering overnight while your tenants sweat. Our techs know to pull the attic hatch first on refrigerant calls in the 91405–91406 corridors. Post-Northridge flex-duct repairs done with foil tape in 1994–1995 have long since failed, and a system that tests low on charge is often just pumping expensively conditioned air into a 150°F attic through a boot that separated three administrations ago. That local knowledge saves you a misdiagnosis and a second truck roll.
Our Emergency & Commercial HVAC Services in Van Nuys
24/7 Emergency HVAC
Van Nuys sits in the deepest interior of the San Fernando Valley heat sink, geographically cut off from coastal marine cooling by the Santa Monica Mountains, so it routinely hits 105–115°F on days when Santa Monica is 72°F — a 30°F+ swing on the same afternoon. Every sizing, ductwork, and equipment-longevity decision here must be calibrated for that Valley-floor thermal punishment, not for generic Southern California conditions. When your compressor locks out on high-pressure limit at 9 p.m. on a 108°F Saturday, we’re answering. Our emergency line routes directly to Gregory Hahn’s on-call rotation, not an offshore answering service. We service your brand, whether it’s a 15-year-old Goodman on a Sherman Way duplex or a Bryant commercial package unit behind a Van Nuys Boulevard retail strip.

Commercial HVAC
Van Nuys’s commercial corridors — Van Nuys Boulevard, Sepulveda Boulevard, and the industrial pockets near Saticoy Street — run a mix of 1960s–1980s low-rise buildings with rooftop package units and newer construction with split systems. We’ve replaced failed economizer controls on Trane units above auto parts stores and diagnosed refrigerant leaks in American Standard splits serving medical offices. From a single mini-split to a full commercial system, we handle the permitting, load calculations, and post-install commissioning. Our 13 years in business means we’ve outlasted most of the fly-by-night operators who used to underbid these jobs and vanish.

Rooftop Unit Service
Rooftop units in Van Nuys take a beating. The combination of continuous summer operation and radiated heat from tar and gravel roofing surfaces pushes discharge air temperatures past design specs. We find cracked heat exchangers, failed blower belts, and economizer dampers seized open from Valley dust. On a 105°F July afternoon, we responded to a no-cool call on Sepulveda Blvd. The Goodman condenser was cycling on high-pressure limit — attic temp was 158°F, and the original flex-duct trunk had separated from the boot. We performed an emergency repair, replaced the duct section with insulated flex, and reset the charge. Diagnosed right the first time.

Chiller Service
While less common in Van Nuys than central LA, chillers serve several medical and light industrial facilities near the 405 corridor. We handle chiller startups, refrigerant analysis, and cooling tower maintenance. The hard water in the Valley municipal supply scales condenser tubes faster than coastal systems, so we factor that into maintenance intervals. If your chiller’s leaving-water temperature is creeping up, call before it fails completely — chiller rentals in August aren’t cheap.

Trusted Brands We Service in Van Nuys
We service your brand. Gregory Hahn holds factory-trained or equivalent experience across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Van Nuys customers, that means we’re not guessing at control sequences or ordering wrong parts. We stock common capacitors, contactors, and blower motors for Carrier and Trane systems locally, and our relationships with Bryant and American Standard distributors get us next-day access to larger components. A technician who only knows one brand’s diagnostic tree will replace parts until something works. We read the actual pressures, temperatures, and amp draws, then fix what’s actually broken.
Common Emergency & Commercial HVAC Problems We See in Van Nuys Homes
- Original flex-duct boots separated during the 1994 Northridge earthquake, taped over with foil tape that fails in 150°F attics. We find this constantly in 1950s–1970s tract homes near Victory Boulevard and Vanowen Street. The system “works” but delivers half the airflow, so the thermostat never satisfies and the compressor runs continuously.
- Oversized units installed for fast cooldown short-cycle in Valley-floor heat, stressing compressors on 105°F+ days. A 5-ton condenser on a 1,200-square-foot house sounds generous until you realize it never runs long enough to dehumidify or reach steady-state efficiency. We see premature compressor failures from this mismatch all summer.
- Undersized package units on 1960s apartment buildings on Van Nuys Blvd can’t handle continuous cooling demand, leading to compressor burnouts. These buildings were designed for window units, and the retrofit package units are often one ton short for the solar load through uninsulated stucco walls.
- Heat pump defrost boards failing in “mild” winters that still hit 35°F at 5 a.m. Van Nuys doesn’t freeze, but it gets cold enough to trigger defrost cycles. Failed sensors or stuck reversing valves leave tenants with electric heat strips pulling 20+ kW all night.
Pricing for Emergency & Commercial HVAC in Van Nuys, CA
We don’t quote blind over the phone, but we won’t leave you guessing either. Here’s what typical Emergency & Commercial HVAC work runs in Van Nuys:

Van Nuys pricing tracks slightly higher than coastal San Diego for equivalent equipment because Valley-floor heat loads demand heavier-gauge electrical, larger condenser pads, and more robust attic insulation on duct runs. Emergency after-hours calls add a trip charge, but we diagnose for free once we’re there — no fee to tell you what’s wrong. Call (844) 875-9451 for an exact quote. Estimates are free.

FAQs — Emergency & Commercial HVAC in Van Nuys
Yes, and we’ll design it specifically for your attic conditions and heat load, not a generic Southern California specification. We typically spec insulated flex-duct with R-8 wrap minimum, sealed with mastic (never foil tape), and routed through the coolest available chase. We may also recommend a high-velocity mini-duct system or ductless mini-split if your attic is too compromised for conventional trunk lines. Call (844) 875-9451 for a load calculation and exact quote — estimates are free.
Usually yes, but the root cause matters. Dirty condensers, failed condenser fans, and overcharge from a previous technician’s “top-off” are common. In Van Nuys, we also find radiated roof heat pushing head pressure past design limits on older units. We clean, measure actual subcooling and superheat, and verify airflow before resetting anything. Call (844) 875-9451 — we’ll diagnose before replacing parts.
Yes, and for many Van Nuys landlords this pays back in 3–5 years through reduced tenant turnover and lower electrical costs. We design multi-zone Mitsubishi or Daikin systems with individual metering capability, mounted on exterior walls or roof frames to preserve parking. The permitting through LA Department of Building and Safety is straightforward for our team — we’ve done dozens. Call (844) 875-9451 to walk the building.
If the heat exchanger is cracked, replace immediately — carbon monoxide risk isn’t negotiable. For other failures, we weigh repair cost against remaining life and efficiency. A $400 ignition module on a 80% furnace with a sound heat exchanger can buy 3–5 more years. A $1,200 blower motor and cracked collector box usually means replacement makes sense. We’ll give you both numbers honestly. Call (844) 875-9451 for an inspection.
Yes, for facilities with chillers up to 100 tons. We carry refrigerant recovery equipment and common gasket sets, and we can stabilize your system while sourcing larger components. Response time to Van Nuys commercial addresses is typically under two hours for chiller emergencies. Call (844) 875-9451 — if we can’t solve it immediately, we’ll tell you straight and help coordinate a rental.
