Why Old Fig Garden Residents Choose Us for Lennox Service
Gregory Hahn founded this company and still leads every technical decision. He grew up in Mira Mesa patching ductwork in houses that had no business being as hot as they were, trained in HVAC diagnostics at Miramar College, and has spent 13 years building Redwood Heating & Air into a shop that carries factory-trained experience across nine major brands, including Lennox. Our coverage extends to Lennox in Clovis and throughout the San Joaquin Valley. We’re not a Lennox dealer. We’re an independent service provider who knows these systems inside and out.
That independence matters in Old Fig Garden. When your 1930s Tudor on First Street needs a compressor replaced, you don’t need a salesman pushing a full system swap because that’s all the dealer is authorized to sell. You need someone who can source an OEM Lennox compressor, install it correctly, and tell you honestly whether the rest of the system has five years left or five months. Our 428 verified reviews averaging 4.6 stars reflect that approach. We service your brand, we diagnose right the first time, and if Gregory wouldn’t put it in his own house, he’s not recommending it for yours.
Common Lennox HVAC Problems We Solve in Old Fig Garden
- Secondary heat exchanger corrosion in SLP98V furnaces. The condensate drainage in these high-efficiency units assumes a modern floor drain or pump setup. Old Fig Garden’s plaster-walled homes from the 1920s often have basement configurations with no floor drain at all, and the acidic condensate backs up, rotting the secondary exchanger from the inside out. We’ve replaced dozens of these in homes near Vassar Avenue where the original gravity furnace left no provision for condensate management.
- High-pressure lockouts in XC20 condensers. Old Fig Garden’s dense mature tree canopy is beautiful, but it sheds debris that collects in attic-mounted air handlers and clogs the coil fins on outdoor units. The XC20’s variable-capacity compressor is sensitive to restricted airflow, and during July weeks when the San Joaquin Valley hits 105–110°F, that debris triggers repeated lockouts. We clean the coils and modify intake screening to prevent recurrence.
- Failed iComfort thermostat sensors from voltage spikes. Many Old Fig Garden homes still run original 60-amp electrical panels that struggle during summer peak demand. The iComfort system in Lennox Signature units expects stable voltage, and when the panel sags under load, the control board throws communication errors or the thermostat goes blank. We diagnose whether it’s a power quality issue or a failed board, and we coordinate with electricians when the panel needs upgrading.
- Cracked heat exchangers in aging ML180UH furnaces. The ML180UH is a workhorse, but 40 years of thermal cycling through Tule fog season takes its toll. December through February brings sustained damp cold to Old Fig Garden, and furnaces that ran minimally for decades now cycle heavily through foggy mornings. Hairline cracks develop where the metal fatigues, creating carbon monoxide risk. We inspect with combustion analyzers and scope cameras, never guess.
- Undersized ductwork in retrofitted systems. When a previous contractor replaced a gravity furnace with a forced-air Lennox without recalculating for the home’s actual load, the blower works against static pressure it wasn’t designed for. We see this in Spanish Colonial Revivals with 12-foot ceilings where the original Manual J was never updated. The result: noisy operation, poor airflow to second-floor rooms, and premature blower motor failure.
Lennox Service in Old Fig Garden: What Local Conditions Mean for Your Equipment
Old Fig Garden sits in a unique spot. The San Joaquin Valley heat sink drives summer temperatures past 105°F routinely, while the same Valley geography produces Tule fog in winter that traps damp cold against your home for weeks. Your Lennox system fights both extremes. But the real challenge here isn’t the climate, it’s the housing stock.
Many Old Fig Garden homes on streets like Vassar Avenue and First Street still have original gravity floor furnaces from the 1920s–30s. A homeowner calls saying “I need a new furnace,” and a contractor unfamiliar with the neighborhood bids a swap, not realizing there’s zero ductwork to connect to. We’ve seen this underbid turn into a $10,000 surprise mid-project. Our crew routinely converts these gravity systems to forced-air Lennox units with custom duct chases routed through closets, preserving original crown molding and lath-and-plaster walls that can’t be replicated. At a 1932 Spanish Colonial Revival on Vassar Avenue, we found a homeowner expecting a simple furnace swap for their no-heat call, but the original gravity floor furnace had no ductwork. Our crew designed a full Lennox SLP98V forced-air system with duct chases hidden inside hallway closets and a fresh-air intake routed through the basement, preserving the original plaster and crown molding while delivering 95% AFUE efficiency. That’s the difference between a technician who knows Old Fig Garden and one who’s just passing through.
Lennox Models & Products We Service in Old Fig Garden
We work on the full Lennox residential and light commercial lineup. The Signature Series includes variable-capacity systems like the XC20 air conditioner and SLP98V furnace, precision equipment that demands proper commissioning, especially in homes where ductwork was retrofitted decades after construction. The Elite Series covers the EL16XC1 single-stage AC and EL296E two-stage furnace, reliable mid-range systems we see frequently in 1990s-era updates to older Old Fig Garden homes. The Merit Series includes the ML14XC1 and ML180UH, straightforward equipment that holds up well when maintained, though the ML180UH’s age in this neighborhood means we’re often discussing replacement timelines honestly.
For critical repairs, we source OEM Lennox compressors, heat exchangers, and control boards. When capacitors or contactors need replacement and OEM is backordered, we use quality aftermarket parts that meet or exceed factory spec, saving you a week of waiting without gambling on reliability. Our truck stock covers the most common Lennox failures for same-day resolution in 93704.

What drives cost? For repairs, it’s parts availability and accessibility. A control board replacement on an accessible attic unit runs toward the lower end. A heat exchanger in a basement with a 6-foot clearance and original plaster to protect lands higher. For installations, the spread reflects whether we’re connecting to existing ductwork or building from scratch, which in Old Fig Garden is often the central question. Our free estimate includes a full load calculation, duct inspection, and honest assessment of repair-versus-replace. Call (844) 875-9451 to schedule.

FAQs — Lennox HVAC in Old Fig Garden
Yes. We’ve developed specific retrofit techniques for Old Fig Garden’s pre-war homes, including duct chases through closets and soffits that avoid cutting into irreplaceable plaster. Our crew treats original millwork as non-negotiable. Call (844) 875-9451 for a walkthrough of your specific layout.
Usually not if the heat exchanger is cracked or the control board is obsolete. The ML180UH is a solid unit, but at 25–30 years old in Old Fig Garden’s climate, replacement often makes more sense than chasing intermittent failures. We assess based on repair cost versus a new system’s efficiency gains and your home’s actual heating load. Call (844) 875-9451 for an honest evaluation.
Yes. Old Fig Garden falls under Fresno’s permitting jurisdiction, and we pull all required mechanical permits for new installations and major modifications. We also coordinate inspections so you’re not chasing city schedules. This is standard on our jobs, not an add-on.
Usually not. In Old Fig Garden, the culprit is typically debris from mature tree canopy clogging the outdoor coil or restricted airflow from attic-mounted air handlers fighting summer heat. We clean the system, check refrigerant charge to spec, and modify intake screening if needed. Refrigerant leaks are less common than airflow problems here. Call (844) 875-9451 for same-day diagnosis.
Yes. This is one of our most common calls in Old Fig Garden. The conversion requires designing a full duct system from scratch, which we route through closets and basement chases to protect original finishes. We size the Lennox equipment to the home’s actual load, not the old furnace’s output. Expect this scope to run toward the upper end of our installation range due to the custom ductwork involved. Call (844) 875-9451 for a detailed estimate.
