Van Nuys isn’t coastal LA. It sits in the deepest interior of the San Fernando Valley heat sink, where the Santa Monica Mountains block marine air and summer attic temperatures regularly hit 150°F. That thermal punishment cracks heat exchangers, degrades flex duct from the 1994 Northridge earthquake, and forces furnace blowers to work in conditions no coastal homeowner faces. We’ve spent 13 years diagnosing these exact Valley-floor failure patterns.

Why Redwood Heating & Air San Diego Is Van Nuys’s Preferred Heating & Furnace Company

Gregory Hahn founded this company and still leads every technical decision. When you call Redwood Heating & Air, you’re not getting a dispatcher sending whichever crew is available. You’re getting a Master Technician who has spent 13 years in the field, certified across nine major HVAC brands including Carrier, Trane, and American Standard.

Our 428 verified reviews averaging 4.6 stars include plenty from Van Nuys homeowners who found us after frustrating experiences with one-brand dealers or rushed seasonal contractors. They mention the same things: we diagnose the actual problem, we explain why it failed, and we fix it without upselling equipment they don’t need.

Response time to Van Nuys matters when your furnace quits on a 35°F January night. We keep common parts stocked for Bryant, Carrier, and Trane systems, the brands we see most often in local 1950s–1970s housing stock. That means fewer return trips and faster restoration of heat.

Our local knowledge runs deep. We know the post-WWII tract homes near Van Nuys Boulevard were built without central heating and later retrofitted with attic duct systems that bake all summer. We know the 1960s apartment buildings on Sepulveda still run original package units. And we know the 91405–91406 corridors still harbor foil-taped flex-duct repairs from 1994 that fail on today’s service calls.

Our Heating & Furnace Services in Van Nuys

Furnace Repair

A typical furnace repair in Van Nuys runs $150–$700. We handle ignitor replacements, blower motor failures, limit switch trips, and the control board issues that surface when 150°F attic heat has been stressing components for decades. On a recent call near Hazeltine Avenue, a homeowner’s 1980s Goodman wouldn’t ignite. We traced it to a cracked inducer housing, replaced it with an OEM part, and had heat restored that afternoon. The salt-laden air drifting over the Santa Monica Mountains from the coast accelerates corrosion on gas valves and flame sensors here, even though Van Nuys feels inland.

Furnace Replacement

Furnace replacement in Van Nuys costs $3,500–$7,500 depending on size, efficiency rating, and ductwork condition. We emphasize this sub-service because so many local furnaces are original to 1950s–1970s construction, running well past their design life in attics that hit 150°F every summer. On a 1950s tract home near Van Nuys Blvd and Osborne St, we found an original gas furnace with a cracked heat exchanger caused by 30 years of thermal stress from 150°F summer attics. We replaced it with a high-efficiency 96% unit and upsized the return duct to handle the Valley’s heat load, all while ensuring the condensate line wouldn’t freeze on the rare 35°F winter nights. Proper sizing matters here. A furnace rated for generic Southern California loads will short-cycle and fail prematurely in Van Nuys’s thermal environment.

Furnace Tune-Up

A furnace tune-up in Van Nuys runs $95–$235 and should happen annually, ideally in October before the first cold snap. Our tune-ups include heat exchanger inspection, gas pressure verification, combustion analysis, and blower amp draw testing. We pay special attention to flex-duct connections in the attic, because the 1994 Northridge earthquake epicenter was just two miles away in Reseda, and those vibrations still surface as separated boots and collapsed duct runs. Catching a cracked heat exchanger during a tune-up prevents carbon monoxide risk. Finding a separated duct prevents you from heating your attic instead of your bedroom.

Heat Exchanger Inspection & Replacement

This is critical work in Van Nuys. The extreme attic heat cycling, summer after summer, fatigues heat exchanger metal far faster than in coastal climates. We inspect with visual borescopes, combustion analyzers, and carbon monoxide testing. If we find cracks, we replace the heat exchanger or recommend furnace replacement depending on age and overall condition. Never ignore a cracked heat exchanger. Carbon monoxide is odorless and deadly, and Van Nuys’s tight 1950s construction can trap it indoors.

Gas Valve Repair

Gas valve failure in Van Nuys often traces to corrosion from salt-laden air that drifts over the Santa Monica Mountains. We test inlet and outlet pressure, check for proper modulation, and replace valves when corrosion compromises the diaphragm or solenoid. This is specialized work that requires proper gas leak detection and line purging. If you smell gas near your furnace, exit the home and call your gas utility first, then call us.

Ignitor Replacement

Hot surface ignitors fail every 3–5 years in normal conditions, but Van Nuys’s thermal stress and voltage fluctuations from heavy summer AC loads can shorten that. We stock ignitors for Carrier, Trane, Bryant, and American Standard systems common in local housing stock. Replacement is typically same-day.

Trusted Brands We Service in Van Nuys

We service your brand. Gregory Hahn holds factory training or equivalent field experience across nine major HVAC manufacturers: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Van Nuys, we see Bryant and Carrier most often in 1970s-era homes, with Trane and American Standard appearing in later renovations. We stock common ignitors, gas valves, blower motors, and control boards for these brands locally, which means faster turnaround when your furnace quits. We’re not tied to any single manufacturer’s product line, so our diagnosis is brand-agnostic. The right fix, not the convenient upsell.

Common Heating & Furnace Problems We See in Van Nuys Homes

• Cracked heat exchangers from extreme attic heat cycling. Van Nuys attics hit 150°F in summer, then drop to near-ambient in winter. That thermal shock fatigues heat exchanger metal year after year, producing cracks that leak combustion gases into conditioned air. We find this most often in furnaces 15+ years old located in unconditioned attics.
• Failed inducer motors and pressure switches from attic dust and debris. Post-WWII insulation in Van Nuys tracts sheds particles that clog inducer ports and pressure switch tubing. The furnace throws an error code or refuses to ignite. We clean or replace components and recommend better air sealing if the attic environment is particularly harsh.
• Gas valve corrosion from salt-laden coastal air. Despite feeling landlocked, Van Nuys receives marine air that clears the Santa Monica Mountains, carrying salt that corrodes gas valve bodies and electrical connections. We see this on furnaces 10+ years old, especially those in homes near the 405 corridor where air movement is stronger.
• Separated flex-duct boots from 1994 Northridge earthquake repairs. Techs working the 91405–91406 corridors quickly learn to pull the attic hatch before diagnosing a refrigerant call: 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. The same failure mode affects heated air in winter.
