Commerce sits in a strange spot for an HVAC company. Roughly 90% of this city is zoned commercial or industrial, which means most heating companies in the area chase warehouse contracts and treat the remaining residential pockets as an afterthought. We don’t. Those mid-century homes near Slauson Avenue and the small residential clusters tucked between distribution centers deserve the same expertise as a 50-ton rooftop unit. And they need more of it, because many of these houses were built in the 1940s through 1960s without central heating, then retrofitted decades later with ductwork squeezed through cramped attics. The static pressure problems and airflow imbalances those retrofits create are exactly the kind of puzzle Daniel has spent ten years solving.

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

357 customers have left verified reviews averaging 4.9 stars, and a growing share of them come from right here in Commerce. That’s not an accident. Word travels fast in a city this size, especially when your neighbor mentions that the same person who answered the phone also showed up with the tools, diagnosed the problem in twenty minutes, and didn’t try to sell a replacement furnace on a unit that just needed a gas valve.

Daniel Okafor serves as both Owner and Lead Technician on every Commerce call. No rotating crews. No “my guy will be there between 8 and 5.” When you schedule with Northstar, you’re scheduling with the person whose name is on the truck and whose reputation is tied to every weld, every pressure test, every combustion analysis.

Response time to Commerce averages under 90 minutes during standard hours for heating emergencies. We’re familiar with the traffic patterns on the 5, the 710, and surface routes like Atlantic Boulevard — knowledge that matters when a furnace goes down during a cold snap and every minute without heat risks frozen pipes in these older wood-frame structures.

Our local knowledge runs deeper than directions. We know which Commerce blocks still have original 1950s ductwork with asbestos wrapping that requires special handling. We know the commercial corridors near Vernon where industrial particulates from rendering and tire manufacturing foul air handlers at rates that would shock a technician from a cleaner suburb. That expertise protects your system and your wallet.

Our Heating & Furnace Services in Commerce

Furnace Repair

A dead furnace in Commerce demands fast action, especially in homes with original single-pane windows and minimal insulation. Our Heating & Furnace team responds with fully-stocked trucks carrying ignitors, gas valves, flame sensors, and control boards for York, Daikin, Bryant, and American Standard units. Most Commerce furnace repairs fall between $175–$825 depending on whether we’re replacing a failed ignitor or addressing a more complex control issue. Daniel diagnoses on-site, explains exactly what’s wrong, and fixes it — no mystery charges, no “we’ll have to come back with parts.”

Furnace Replacement

When a heat exchanger cracks or a 25-year-old furnace finally gives out, replacement becomes the only safe option. In Commerce’s retrofitted homes, this gets complicated fast. Those cramped attic spaces often require creative solutions: downflow conversions, compact 80% units when venting won’t support 90%+ efficiency, or duct modifications to handle proper static pressure. We size every replacement using Manual J load calculations that account for Commerce’s urban heat island effect — the dense pavement and metal roofing surrounding residential pockets drives cooling loads higher than textbook calculations suggest, and heating systems must compensate for the thermal inefficiency of these older structures. Typical furnace replacement in Commerce runs $4,130–$8,850 including unit, labor, and necessary duct adjustments.

Furnace Tune-Up

Annual furnace maintenance in Commerce costs $95–$235 and pays for itself in prevented breakdowns. Our tune-ups include combustion analysis, heat exchanger inspection with borescope, gas pressure verification, and airflow measurement. In Commerce specifically, we pay extra attention to filter loading rates — homes near the Vernon industrial corridor see far more airborne particulates than typical LA Basin residences, and a clogged filter strains blowers, cracks heat exchangers from overheating, and pumps unburned gas into living spaces. We also check for duct leakage in these retrofitted systems; it’s common to find 30% or more conditioned air escaping into attics that were never designed to handle it.

Heat Exchanger Inspection & Replacement

A cracked heat exchanger is a silent killer — odorless carbon monoxide leaking into your home while the furnace runs normally. In Commerce’s older furnaces, especially those cycling heavily through poorly balanced duct systems, heat exchanger fatigue shows up earlier than manufacturer estimates suggest. Daniel inspects every heat exchanger with a fiber-optic borescope, documents findings with photos you can see, and explains exactly why replacement is or isn’t necessary. When replacement is needed, we handle the full job: furnace removal, new unit installation, combustion testing, and CO detector verification. We also offer Air Quality & Ventilation in Commerce services to address the broader indoor air challenges these older homes face.

Ignitor & Gas Valve Repair

Hot surface ignitors fail every 3–5 years in normal conditions; in Commerce, voltage fluctuations from aging grid infrastructure and the thermal stress of frequent cycling in inefficient systems can shorten that lifespan. Gas valves stick from sediment in lines or fail from coil burnout. Both failures leave you cold, and both are same-day fixes when your technician carries the right parts. Daniel stocks ignitors and gas valves for all nine major brands we service, which means one trip, one fix, one invoice.

Trusted Brands We Service in Commerce

We carry factory-authorized parts and technical documentation for nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Commerce customers, this means no referral runarounds when your Daikin furnace throws a fault code or your York unit needs a proprietary control board. Daniel is certified to work on all nine brands, so the same person who diagnosed your system can repair it without waiting for a “specialist” who may or may not show up. We also handle Heat Pump & Mini Split in Commerce for properties where ducted heating isn’t practical — a common scenario in those converted garage apartments and small commercial spaces near the Citadel Outlets.

Common Heating & Furnace Problems We See in Commerce Homes

• Uneven heating from retrofitted ductwork. The mid-century homes in Commerce’s residential pockets were never designed for forced-air systems. Ducts run through attics with sharp bends, improper sizing, and too few returns. We measure static pressure and airflow room-by-room, then rebalance dampers or add returns where possible.
• Short cycling from oversized furnaces. Previous installers often sized replacement units by matching the old equipment’s BTU rating — but those original units were frequently oversized themselves. The result: furnaces that blast heat, satisfy the thermostat too quickly, and never run long enough to dehumidify or distribute air evenly.
• Failed ignitors in high-cycling systems. When a furnace starts and stops constantly, the ignitor undergoes repeated thermal shock. In Commerce’s older homes with poor insulation, that cycling happens more often, and ignitor replacement becomes a recurring expense until the underlying cause is fixed.
• Corroded heat exchangers from combustion byproducts. Furnaces with improper gas mixture or inadequate venting produce acidic condensation that eats exchangers from the inside. We catch this with combustion analysis during tune-ups, before CO enters your living space.
