Fast, Reliable Heating & Furnace Across Commerce
Commerce sits in the LA Basin heat sink where summer highs push into the low-to-mid 90s with zero coastal relief, and the industrial density surrounding your property means your furnace works harder than equipment just miles west. A typical furnace repair in Commerce runs $150–$700, and our Heating & Furnace team usually responds same-day to calls along Telegraph Road, the I-710 corridor, and the 90101 zip. We’ve spent 13 years learning what fails here and why. Call (844) 875-9451 for a free estimate.
Why Redwood Heating & Air San Diego Is Commerce’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision. That matters in Commerce, where most HVAC companies send residential technicians into industrial settings they’re not certified to handle. Gregory holds a Master Technician designation, and our 13 years in business include heavy commercial work across nine major brands.
We’ve earned 428 verified customer reviews averaging 4.6 stars, and that reputation extends into Commerce’s industrial core. Our technicians carry the certifications and lift equipment for rooftop package units, not just residential split systems.
Response time to Commerce typically runs 45–90 minutes from dispatch, depending on whether you’re near the I-710/Slauson interchange or further south toward the 5 Freeway. We know which facilities have loading dock constraints, which roofs require boom lifts versus stair access, and how to coordinate with your maintenance manager without shutting down operations.
Our Heating & Furnace Services in Commerce
Furnace Repair
Furnace repair in Commerce is a different discipline than residential work. Diesel soot from the I-710 freight corridor clogs combustion air intakes, causing flame rollout and limit switch trips within weeks of cleaning. We see this pattern constantly on rooftop units above warehouses near Telegraph Road and Bandini Boulevard. Our technicians carry combustion analyzers calibrated for high-particulate environments, and we stock replacement limit switches, ignitors, and gas valves for Trane, Lennox, and Rheem commercial units. A standard furnace repair in Commerce runs $150–$700 depending on whether we’re cleaning a fouled burner assembly or replacing a cracked heat exchanger.

Heat Exchanger Replacement
Heat exchangers crack prematurely in Commerce. The culprit is thermal cycling from oversized units short-cycling in mild weather, combined with diesel-soot accumulation that forces the furnace to run longer to hit setpoint. We recently serviced a 15-ton Trane rooftop gas furnace on a distribution center along Telegraph Road near the I-710 corridor. The unit’s heat exchanger had cracked prematurely due to thermal stress from the constant diesel-soot accumulation on the condensing coils, which had gone uncleaned for two seasons. We replaced the heat exchanger under warranty and installed a custom filter-minder system to alert the facility manager when filter loading hits critical levels. This is the level of diagnosis you get when Gregory Hahn’s Master Technician expertise guides every repair.

Furnace Tune-Up
A furnace tune-up in Commerce should happen twice yearly, not annually. Industrial-grade rooftop units here suffer accelerated corrosion of burner assemblies from airborne chemical particulates, and coil fouling progresses roughly twice as fast as comparable equipment in residential East LA. Our tune-up runs $80–$200 and includes combustion analysis, burner inspection, heat exchanger integrity testing, and coil cleaning with foaming agents formulated for diesel-soot removal. We document filter pressure drop and photo-document coil condition so your maintenance records support warranty claims.

Furnace Replacement
When replacement makes more sense than repair, we size for actual load, not rule-of-thumb. Many Commerce facilities run oversized equipment that short-cycles itself to death. We perform Manual J load calculations and match the unit to your square footage, ceiling height, and process heat loads. From a single rooftop package unit to a multi-zone commercial system, we install equipment from nine major brands including Trane, Lennox, Goodman, and Rheem.

Trusted Brands We Service in Commerce
We service your brand, not just the one we sell. Gregory Hahn built Redwood Heating & Air on multi-brand fluency across Carrier, Trane, Lennox, Daikin, Rheem, York, Goodman, Bryant, and American Standard. For Commerce customers, this means we stock common parts locally for Trane and Lennox commercial rooftop units, the dominant brands in this industrial market. We don’t wait two days for a proprietary control board. Our warehouse carries ignitors, gas valves, flame sensors, and limit switches for the equipment actually sitting on your roof. Fast turnaround matters when your distribution center can’t hold temperature.
Common Heating & Furnace Problems We See in Commerce
- Diesel soot chokes combustion air intakes. Rooftop condenser coils on Commerce warehouses along the I-710 freight corridor accumulate diesel soot and industrial particulate so aggressively that technicians here schedule coil cleanings roughly twice as often as they would on comparable equipment just a few miles west in a residential neighborhood. Skipping a cleaning cycle can cut system efficiency sharply before the next service visit, and the backpressure forces your furnace to work harder and fail sooner.
- Burner assemblies corrode from chemical particulates. Airborne emissions from nearby manufacturing plants accelerate rust and oxidation on steel burner components. We inspect for this specifically during tune-ups, not as an afterthought.
- Oversized units short-cycle into heat exchanger cracks. Commercial heat exchangers crack prematurely from the constant thermal cycling caused by oversized units short-cycling in mild weather, a common problem in Commerce’s industrial facilities. Proper load calculation at replacement prevents this expensive failure mode.
- Flame rollout from restricted airflow. When combustion air intakes clog with soot, flames don’t stay in the burner box. This trips rollout switches and creates a genuine safety hazard. We catch this before it escalates.

FAQs — Heating & Furnace in Commerce
Your Commerce furnace faces diesel soot from the I-710 corridor and industrial particulates that clog filters and coils at roughly double the rate of residential equipment in East LA. The localized air-quality conditions accelerate filter loading and condenser coil fouling well beyond what nearby residential areas experience. Skipping a cycle here risks heat exchanger damage before your next scheduled visit. Call (844) 875-9451 to set up a six-month interval that protects your equipment.
We do both, though Commerce’s housing stock is limited. The modest mid-20th-century single-family homes and small apartment buildings in 90101 represent a small fraction of our calls here. Most of our Commerce work is commercial rooftop package units, but we bring the same Master Technician standards to residential jobs when they arise. If you live in one of the residential pockets near Bandini Boulevard or the eastern edge of the city, we’ll handle your furnace with the same expertise. Call (844) 875-9451 for a free estimate.
Heat exchanger replacement and combustion air intake cleaning are the top two. Diesel soot from I-710 truck traffic clogs furnace combustion air intakes, causing flame rollout and limit switch trips within weeks of cleaning. The thermal stress from running dirty eventually cracks heat exchangers. We address the root cause with aggressive filter and coil protocols, not just the symptom. Call (844) 875-9451 to inspect your unit before it reaches that point.
Yes, we coordinate phased changeouts and temporary heating solutions for temperature-sensitive inventory. Our team plans around your receiving schedules and peak shipping periods. We’ve replaced furnaces on active distribution centers along Telegraph Road during operating hours by sectioning the work and using portable heaters for zones under construction. Call (844) 875-9451 to discuss your operational constraints.
Every six months, minimum. Rooftop condenser coils on Commerce warehouses along the I-710 freight corridor accumulate diesel soot and industrial particulate so aggressively that technicians here schedule coil cleanings roughly twice as often as they would on comparable equipment just a few miles west. A furnace tune-up in Commerce runs $80–$200 and includes the combustion analysis and coil cleaning your equipment needs to survive this environment. Call (844) 875-9451 to book your first cycle.
