Lennox Air Duct Cleaning in East Palo Alto, CA | Northstar Air Duct Cleaning Service San Francisco
Independent Lennox air duct cleaning in East Palo Alto runs $280–$520 for most residential systems, with same-day scheduling available when we’re already on the Peninsula. What separates our work here is the pairing: we know Lennox Merit, Elite, and Signature equipment inside-out, and we’ve spent 14 years in East Palo Alto’s specific conditions — the diesel corridor along US-101, the bay moisture in crawl spaces, the original 1950s galvanized ductwork that neighboring cities replaced decades ago. Brian Rivera — owner and lead technician — handles your job personally. Call (855) 908-0725 for a free estimate.
Why East Palo Alto Residents Choose Us for Lennox Service
We’ve cleaned Lennox systems in East Palo Alto long enough to recognize the patterns. The G16 gas furnace in a Weeks neighborhood tract home isn’t the same machine as a G16 in a Menlo Park remodel — not when it’s been breathing bay-moist air through degraded flex duct for forty years.
Brian Rivera grew up in San Francisco’s Excelsior District and built his mechanical foundation at City College of San Francisco. For 14 years he’s run Northstar with one rule: he shows up on every job himself. That means the person with 1,209 verified reviews and a 4.9-star average is the same one crawling under your house with a Rotobrush and Nikro vacuum, not some dispatched subcontractor you’ve never met.
We carry OEM Lennox heat exchangers and blower motors for critical repairs, and we stock high-quality aftermarket flex duct, mastic, and insulation for the rebuilds East Palo Alto’s aging housing stock demands. Professional-grade Abatement Technologies HEPA equipment, not the side-van tools a generalist HVAC company brings. “I’ve been in San Francisco ducts for 14 years — I’ll tell you what’s there, not what sells.”
Common Lennox Air Duct Cleaning Problems We Solve in East Palo Alto
- Cracked G16 heat exchangers from decades of deferred maintenance. East Palo Alto’s rental-heavy housing stock means many Lennox G16 gas furnaces in 1950s tract homes haven’t seen proper combustion analysis in a generation. We inspect every duct cleaning job for carbon monoxide risk — because a cracked exchanger in a sealed crawl space isn’t a maintenance issue, it’s a safety issue.
- Merit Series evaporator coil corrosion from salt-laden bay humidity. Homes near the Bay Levee pull marine air straight off the water. Lennox Merit coils in these conditions develop accelerated pitting and fin degradation. Our evaporator coil cleaning includes treatment with Guardsman-grade protectants, not just a rinse.
- Signature Series blower motor failure from clogged return plenums. Tenant turnover in East Palo Alto rental units often means filters that haven’t been changed in years. Debris chokes the return, the Signature blower works harder, bearings fail prematurely. We video-inspect the plenum before quoting — you’ll see what we see.
- Collapsed flex duct in raised-foundation crawl spaces. On streets throughout the Weeks neighborhood, we’ve pulled flex runs where bay moisture has degraded the insulation wrap so completely the duct has flattened against the crawl space floor. Zero airflow to the register. Homeowner thinks it’s a furnace problem.
- Mold contamination from dual particulate exposure. East Palo Alto’s position between US-101’s diesel corridor and the Bay shoreline creates a combination we don’t see in single-exposure cities: black carbon particulates on return grilles, mold spores in supply ducts. Lennox systems here need more than standard cleaning — they need source-removal protocols designed for this specific burden.
Lennox Service in East Palo Alto: What Local Conditions Mean for Your Equipment
East Palo Alto’s location between the US-101 diesel corridor and the Bay shoreline creates a dual particulate burden: black carbon from truck exhaust settles on return grilles while bay moisture in crawl spaces fosters mold — a combination that contaminates Lennox ductwork faster than in any single-exposure city on the Peninsula.
Here’s what that looks like in practice. On a call in the Weeks neighborhood, our crew found a Lennox Elite gas furnace pulling air through a flex duct run in a raised foundation crawl space that had been waterlogged during a king tide. The interior liner was black with mold, and the insulation wrap had collapsed, choking off airflow to the supply registers. We removed the damaged flex, treated the crawl space with antimicrobial, and replaced the run with new insulated flex and airtight mastic seals — restoring the Lennox system’s efficiency and clearing the musty odor the tenant had smelled for years.
That job required three things most generalists don’t bring: Rotobrush and Nikro equipment for source removal, knowledge of Lennox Elite airflow specs to size the replacement flex correctly, and the crawlspace experience to spot that king-tide waterline on the foundation wall. Brian Rivera was on-site for all of it.
Lennox Models & Products We Service in East Palo Alto
We work on the full Lennox residential line: Merit Series single-stage systems common in original East Palo Alto tract homes; Elite Series two-stage equipment in properties that saw partial HVAC updates; Signature Series variable-capacity units in the minority of renovated properties; and the venerable Lennox G16 gas furnace — still running in more East Palo Alto homes than you’d expect, given its age.
For critical components — heat exchangers, blower motors, control boards — we specify OEM Lennox parts. For duct infrastructure repairs, we use high-quality aftermarket flex duct, mastic, and insulation that meets or exceeds original specifications. We stock common Lennox blower assemblies and heat exchanger gaskets locally for Peninsula jobs, which means most East Palo Alto repairs don’t wait on shipping.
Every Lennox duct cleaning we perform includes video inspection of the trunk line, evaporator coil assessment, and return grille particulate analysis — the diagnostics that tell us whether you’re looking at maintenance or a deeper system issue.
Lennox Service Pricing in East Palo Alto
Most residential Lennox air duct cleaning in East Palo Alto falls between $280 and $520, depending on system size, accessibility, and contamination level. Here’s how that breaks down:
- Standard Lennox duct cleaning (single system, up to 12 vents): $280–$380
- Lennox duct cleaning + evaporator coil treatment: $380–$460
- Full Lennox service with crawlspace flex duct repair/replacement: $420–$520+
- Video inspection and written assessment: included with all cleanings
- Dryer vent cleaning bundled with Lennox duct service: $85–$120 add-on
What drives cost? Crawlspace access in East Palo Alto’s raised-foundation homes takes longer than slab-grade work. Mold remediation adds treatment steps. And rental properties with decades of deferred maintenance often need joint sealing and insulation wrap replacement beyond basic cleaning.

FAQs — Lennox Air Duct Cleaning in East Palo Alto
Yes, restricted airflow from clogged ducts or collapsed flex runs forces a Lennox furnace to hit high-limit and shut down prematurely. In East Palo Alto, we see this most in rental properties near the Bay Levee where crawlspace moisture has degraded ductwork. We video-inspect first to confirm the cause before quoting any work. Call (855) 908-0725 for a free diagnostic — estimates are free.
Yes. We use Abatement Technologies HEPA-negative-air equipment on every East Palo Alto job, with particular attention to Lennox systems in bayside homes where marine humidity drives mold colonization. Source removal — physically extracting contamination — outperforms chemical-only approaches. The HEPA protocol is standard on our jobs, not an upsell.
Every 2–3 years for Lennox systems within two blocks of US-101, given the elevated diesel particulate load. Homes closer to the Bay Levee with crawlspace moisture issues may need annual evaporator coil treatment even if full duct cleaning isn’t yet required. We assess particulate loading with a visual inspection — call (855) 908-0725 and we’ll tell you where your system stands at no charge.
Regularly. East Palo Alto’s rental-heavy housing stock means we’ve worked on Lennox systems that haven’t been opened in 20–30 years. We document everything with video, provide written condition reports for property managers, and prioritize safety issues like G16 heat exchanger integrity. Owner Brian Rivera coordinates directly with landlords or property management — no tenant middleman required.
Coil treatment is a foaming clean and antimicrobial protectant application to your Lennox evaporator coil — the component that sits above your furnace and actually removes humidity from your air. Dirty ducts often mean dirty coils, since the same airflow passes through both. In East Palo Alto’s salt-humidity environment, we recommend coil treatment with every duct cleaning for Lennox Merit and Elite systems. The add-on runs $100–$120. Call (855) 908-0725 for exact pricing on your unit — estimates are free.
