Lennox HVAC in Palermo, CA | Redwood Heating & Air San Diego
Independent Lennox service in Palermo runs $150–$700 for most repairs, and we stock OEM and quality aftermarket parts to finish most jobs same-day, just as we do for Lennox in Oroville East. What makes our Lennox work different here is the post-2018 housing reality: Palermo’s sudden influx of displaced residents moved into manufactured homes and older stick-built properties with mismatched, neglected systems that need brand-specific diagnosis, not generic troubleshooting.

Why Palermo Residents Choose Us for Lennox Service
We’ve been working on Lennox equipment since before the Merit Series even existed, and that matters in Palermo because your system isn’t failing in a vacuum. It’s failing in 105°F valley heat, or through Tule fog cycles, or inside a manufactured home with belly-wrap ductwork that was never designed for the air handler someone bolted to it.
Gregory Hahn founded this company and still leads every technical decision. He trained at Miramar College and spent 13 years building Redwood Heating & Air into a shop that carries factory-level fluency across nine major brands, including Lennox. We don’t dispatch interchangeable crews who learned one product line at a dealer seminar. When we pull up to a Palermo job, we’re reading the unit’s history in the refrigerant pressures, the capacitor bulge, the heat exchanger color. That’s the difference between a parts-changer and a technician who can tell you whether your SL28XCV coil leak is isolated or systemic.
Our Lennox sales & service approach is independent. We’re not a Lennox authorized dealer, which means no corporate script pushing new equipment when your existing unit has honest life left. We source OEM Lennox compressors and heat exchangers for critical repairs to maintain factory clearances, but for capacitors, contactors, and fan motors we often choose quality aftermarket equivalents that ship faster and cost less. If I wouldn’t put it in my own house, I’m not recommending it for yours.
428 verified reviews averaging 4.6 stars across 13 years. That’s not a marketing number; it’s the record of homeowners who got straight answers instead of upsells.
Common Lennox HVAC Problems We Solve in Palermo
- Evaporator coil leaks in Signature SL28XCV units. Formicary corrosion eats these coils from the inside out, and Palermo’s post-Camp Fire dust load accelerates it. Ash-laden particulate settles on wet coils, changes the pH, and turns a 10-year coil into a 5-year failure. We pressure-test, isolate the leak zone, and replace with OEM copper rather than patching.
- Compressor failures in Merit ML14XC1 condensers. The 105°F+ Sacramento Valley heat dome pushes run capacitors past their tolerance. Weak caps cause hard starts, and hard starts cook compressors. We test inrush current under load, not just microfarads on a bench, because a cap that reads fine at 75°F can collapse at 105°F.
- Heat exchanger cracks in older G60 furnaces. Palermo’s Tule fog mornings drop temps to the mid-20s, then afternoons climb to the 60s. That thermal cycling fatigues steel. We scope every heat exchanger with a borescope camera during furnace service, because a cracked exchanger in a tight manufactured home is a CO risk you don’t gamble with.
- Ignitor failures in SLP98V ultra-low NOx furnaces. Sediment from corroding gas lines in Palermo’s 1960s–80s stick-built homes fouls the ceramic ignitor surface. We clean the manifold orifice and replace the ignitor with an OEM silicon nitride part that tolerates the contamination better than the original.
- Ductwork collapse in manufactured home retrofits. Belly-wrap duct systems in Palermo’s high-density manufactured housing deteriorate under summer heat and rodent pressure. We fabricate transition plenums to adapt 10-inch round openings to 14-inch supplies when the original Lennox air handler gets replaced with a mobile-home-rated unit.
Lennox Service in Palermo: What Local Conditions Mean for Your Equipment
Palermo sits on the Sacramento Valley floor in Butte County just west of the Camp Fire burn zone, and that geography rewrote the HVAC playbook here in 2018. The Paradise disaster pushed thousands of displaced residents into this community almost overnight, creating a surge of occupied manufactured homes, hastily-rented older properties, and new infill construction similar to what we see with Lennox in South Oroville. All of it came with wildly mismatched or neglected systems that local technicians now triage daily.
For Lennox owners specifically, this means a failure pattern you won’t see at the same frequency in Chico or Lennox in Oroville. Homes that sat vacant for years after 2018 developed evaporator coils packed with ash-laden dust, and ductwork sealed with mastic that crumbles on contact. We recently serviced a Lennox Merit ML14XC1 in a manufactured home off Pentz Road where the compressor had locked from a swollen start capacitor after three days without cooling in 105°F heat. We bypassed the hard-start kit temporarily, swapped in a new capacitor, added a PTCR relay to prevent recurrence, and fabricated a transition plenum to adapt the existing belly-wrap duct’s 10-inch round opening to the 14-inch supply. That’s not a standard repair. That’s a Palermo-specific repair.
The valley floor heat dome makes cooling capacity a life-safety concern, not a comfort issue. Winters bring dense Tule fog and overnight lows in the mid-20s. Your Lennox system isn’t just fighting seasonal change; it’s fighting a climate that stresses every component differently than the foothill towns ever did.
Lennox Models & Products We Service in Palermo
We work on the full Lennox residential and light-commercial lineup: Merit Series (ML14XC1, ML180UH), Elite Series (EL18XPV, EL296E), Signature Series (SL28XCV, SLP98V), and XC Series (XC25, XC20). We also service legacy G60 furnaces and earlier R22-era condensers still running in Palermo’s older ranch homes.
Our parts strategy is specific to the repair. For compressors and heat exchangers, we use OEM Lennox components to maintain factory clearances and warranty compatibility. For capacitors, contactors, and fan motors, we stock quality aftermarket equivalents that ship faster and perform identically in field conditions. We advise replacement over repair when compressor labor exceeds 60% of new system cost, or when an 8+ year old unit has already had one major component failure. No one benefits from throwing good money at a heat exchanger when the coil is leaking next season.
For manufactured homes on permanent foundations, we carry mobile-home-rated air handlers and understand the non-standard duct configurations that come with them, a specialty we also apply to Lennox service in Thermalito. That’s a specialty you don’t find at every shop.
Lennox Service Pricing in Palermo
| Service | Price Range |
|---|---|

What drives cost? Access difficulty matters in Palermo’s manufactured homes, where belly-wrap ducts and tight utility closets add labor time. Parts availability matters too; we stock common Lennox capacitors and contactors locally, but a Signature Series variable-speed blower module might need overnight shipping. Age of equipment matters most of all. A 15-year-old ML14XC1 with a locked compressor is a different conversation than a 5-year-old EL18XPV with a failed sensor.
Every estimate is free, and we itemize before any work starts. Call (844) 875-9451 for exact pricing on your specific Lennox unit.

FAQs — Lennox HVAC in Palermo
My Lennox furnace keeps short-cycling — is it the gas valve or something else in Palermo’s Tule fog?
It’s usually not the gas valve. Short-cycling in Palermo’s fog season is most often a dirty flame sensor or restricted condensate drain. The moisture load from dense fog trips pressure switches or causes the control board to read weak flame signal. We clean the sensor with fine steel wool and test microamps under load, then verify the drain slope because standing water in a trap will lock out the furnace before the house warms. Call (844) 875-9451 and we’ll diagnose it properly.
I need a new Lennox AC for my manufactured home on a permanent pad near Palermo — do I need a mobile-home-rated unit?
Yes. California HUD code and Title 25 require mobile-home-rated air handlers for manufactured housing, even on permanent foundations. Standard residential Lennox cabinets won’t pass inspection, and the duct connections are wrong for belly-wrap systems. We install mobile-home-rated EL296E and ML180UH configurations with proper transition plenums. Call (844) 875-9451 for a free sizing estimate.
My Lennox Signature SL28XCV is new but the air doesn’t feel cold — could it be the ductwork from the original 1960s house?
Almost certainly. The SL28XCV is a 28 SEER variable-capacity system that modulates between 35% and 100% output. Original 1960s ductwork in Palermo’s ranch tracts was sized for single-stage 8–10 SEER equipment and leaks 25–40% of conditioned air into the attic. Your system is producing cold air; it’s losing it before it reaches the rooms. We perform duct blaster testing and seal with mastic, not tape. Call (844) 875-9451 for a duct evaluation.
After the Camp Fire, my home sat empty for years — the old Lennox ML14XC1 still runs but smells musty. What’s that?
It’s microbial growth on the evaporator coil and in the drain pan from years of stagnant moisture plus ash-laden dust that settled during vacancy. The ML14XC1’s coil design traps debris, and Palermo’s post-2018 reoccupation pattern means we see this constantly. We deep-clean the coil with foaming cleaner, treat the pan with antimicrobial, and verify the drain line is clear. Sometimes the ductwork needs attention too if rodents nested during the empty years. Call (844) 875-9451 — estimates are free.
My Lennox heat pump’s outdoor fan runs but the compressor won’t start — could the capacitor be bad from the valley heat?
Yes, and it’s the most common summer failure we see in Palermo. The run capacitor weakens under repeated 105°F+ thermal stress, losing microfarad capacity until the compressor can’t generate enough torque to overcome refrigerant pressure. The fan runs on lower amperage, so it keeps spinning while the compressor hums and trips on thermal overload. We test capacitance under load, not just with the power off, because a failing cap can read borderline at rest and collapse under start-up demand. Call (844) 875-9451 — we stock replacements for most Lennox models and can usually get you running same-day.
