Heating & Furnace in Van Nuys — Same-Day Service, Done Right the First Time

Fast, Reliable Heating & Furnace Across Van Nuys

Van Nuys sits in one of the most punishing thermal environments in California. When your furnace quits on a January morning or your heat exchanger starts showing cracks after a decade of Valley temperature swings, you need a technician who understands what this climate does to equipment. We’re Northstar Heating & Air, and we make the run to Van Nuys from our base in the broader metro area with the tools and parts to fix it right the first time. Daniel Okafor, our owner and lead technician, handles the diagnostics personally — not a rotating subcontractor, not a dispatcher sending someone you’ve never met.

Why Northstar Heating & Air San Francisco Is Van Nuys’s Preferred Heating & Furnace Company

Our Heating & Furnace team has built a 4.9-star reputation across 357 verified reviews by showing up, diagnosing honestly, and standing behind the work. Van Nuys customers specifically tell us they chose us after getting vague quotes from franchise operations that couldn’t name the technician who’d actually arrive.

Daniel personally handles every Van Nuys call. That means the person quoting your furnace replacement is the same person installing it, with 10 years of field experience and certification on 9 major brands including Trane, Lennox, Goodman, and Rheem. No handoffs, no surprises.

Response time to Van Nuys typically runs same-day for furnace repairs, and we carry common ignitors, gas valves, and heat exchanger inspection tools on every truck. We’ve learned the hard way that a 1950s ranch on Kittridge or a two-story apartment complex near Van Nuys Boulevard can’t wait three days for heat.

Our local knowledge runs deeper than GPS. We know which Van Nuys neighborhoods built during the 1945-1968 tract boom still run original ducting through attics that hit 140°F in summer, and we check those runs first when winter heating performance drops off.

Our Heating & Furnace Services in Van Nuys

Furnace Repair in Van Nuys

A typical furnace repair in Van Nuys runs $175–$825, depending on whether we’re replacing a failed ignitor or tracing a more complex gas valve issue. The Valley’s extreme temperature swings — from 115°F summer peaks to occasional 38°F winter lows — stress expansion joints, heat exchangers, and ignition systems on a different cycle than coastal equipment. We see cracked heat exchangers earlier in Van Nuys than in Santa Monica or Venice, not because of installation quality, but because the thermal delta here forces metal to expand and contract more aggressively across its service life. Daniel diagnoses these patterns personally, and we stock ignitors and gas valves for Goodman, Rheem, and Lennox systems commonly found in local tract housing.

Furnace Replacement in Van Nuys

When a furnace hits 15-20 years in Van Nuys, replacement often makes more sense than sinking money into a failing heat exchanger or corroded gas valve. We size replacements for the actual load this climate demands, not a generic square-footage chart. A 1950s stucco ranch near Victory Boulevard with original single-pane windows and minimal attic insulation needs a different calculation than a 1980s two-story near Burbank Boulevard with upgraded envelope. We install Trane, Lennox, Goodman, and Rheem systems with proper static pressure testing after install, because we’ve seen too many replacements underperform when ductwork designed for a 1950s blower gets paired with a modern high-efficiency unit.

Furnace Tune-Up in Van Nuys

A furnace tune-up in Van Nuys costs $95–$235 and should happen every fall before the first cold snap. Our tune-up includes combustion analysis, heat exchanger inspection with a borescope, gas pressure verification, and amp draw on the blower motor. In Van Nuys specifically, we also inspect attic duct connections because the summer heat cycling in those 140-160°F attics loosens tape and separates flex duct from collars. Catching that in October beats discovering it when your furnace runs constantly in January and still can’t hold temperature. We also handle Air Quality & Ventilation in Van Nuys for customers who want their full system optimized.

Heat Exchanger Inspection & Replacement

This is the safety-critical one. A cracked heat exchanger can leak carbon monoxide into your living space, and in Van Nuys’s tightly sealed postwar ranches with minimal fresh air infiltration, that risk concentrates faster than in draftier construction. We inspect with visual borescope and combustion analysis; if we find cracks, we red-tag the unit and walk you through replacement options. We don’t patch heat exchangers — it’s not a repair that meets our standard, and it won’t meet yours. For homes with aging systems near Hazeltine Avenue or the older apartment stock along Van Nuys Boulevard, we recommend annual heat exchanger checks once the unit passes 12 years.

Trusted Brands We Service in Van Nuys

We’re certified to work on 9 major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — which means no referral runarounds when your system needs parts. For Van Nuys customers, we stock common ignitors, gas valves, and blower components for Trane, Lennox, Goodman, and Rheem systems locally, cutting wait times on repairs that might otherwise stretch days. Nine major brands, one company, one technician who owns the outcome. That’s the difference between a franchise dispatch board and an owner who answers his own phone.

Common Heating & Furnace Problems We See in Van Nuys Homes

• Heat exchanger cracks in 15+ year systems. The Valley’s extreme thermal cycling — 80°F daily swings are normal — fatigues heat exchanger metal faster than in moderate climates. We catch these with borescope inspection during tune-ups, and we red-tag immediately when found.
• Failed ignitors after summer dormancy. Van Nuys furnaces sit idle for 6-8 months while AC runs hard, then fire up in November. That long layover lets ignitors collect attic dust and moisture; the first cold snap kills weakened ones. We replace with OEM parts, not universal knockoffs.
• Gas valve failures from sediment. Older Van Nuys neighborhoods with original gas piping can deliver particulate that gums valve seats over years. We test inlet and manifold pressure, clean where possible, and replace when calibration drifts outside spec.
• Duct separation in superheated attics. The 140-160°F attic temperatures in Van Nuys’s low-pitched ranch roofs degrade duct tape and sag flex duct off hangers. Your furnace runs, but 20% of the heat never reaches the rooms. We check this on every no-heat call in pre-1970 housing stock.
