Lennox HVAC in Clovis, CA | Redwood Heating & Air San Diego
We provide independent Lennox service across Clovis’s 93611, 93612, 93613, and 93619 ZIP codes — no manufacturer affiliation, just 13 years of hands-on experience with the exact builder-grade Lennox Merit systems that dominate this market. What sets our Lennox work apart in Clovis is our familiarity with the specific failure patterns of ML14XC1 condensers and G60 furnaces in the city’s oversized two-story tract homes, where single-zone systems hit simultaneous end-of-life under 105°F San Joaquin Valley heat.

Why Clovis 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 with his uncle, trained in HVAC diagnostics at Miramar College, and has spent 13 years building Redwood Heating & Air into a shop that diagnoses right the first time. That matters in Clovis, where the density of same-vintage Lennox systems means a generalist wastes hours figuring out problems we’ve seen dozens of times — including in nearby communities like Lennox in Old Fig Garden.
We’re certified to service nine major HVAC brands — Carrier, Trane, Lennox, Daikin, Rheem, York, Goodman, Bryant, and American Standard — which means we evaluate your Lennox system on its actual condition, not on what a single-brand dealer wants to sell you. Our Lennox sales & service approach uses OEM parts for critical components like compressors and heat exchangers, quality aftermarket capacitors and contactors that often exceed OEM specs, and straight talk about whether repair or replacement makes sense. With 428 verified reviews averaging 4.6 stars, our reputation is built on telling homeowners their system has two good years left instead of pushing a replacement they don’t need yet.
Common Lennox HVAC Problems We Solve in Clovis
- Compressor burnout in Lennox ML14XC1 condensers. These builder-grade units from the 2000s were installed by the thousands in Clovis master-planned communities. During consecutive 105°F+ days, they run at high head pressure for weeks straight. The compressor overheats, the thermal overload trips repeatedly, and eventually the winding fails entirely. We’ve replaced dozens in northeast Clovis where the 93619 heat island effect pushes equipment harder than the original sizing calculations allowed.
- Cracked secondary heat exchangers in Lennox G60 furnaces. Clovis winters are mild enough that oversized G60 units cycle on and off all night, never reaching steady-state operation. Condensate pools in the secondary heat exchanger, and the thermal cycling stress creates cracks that leak combustion gases into the airflow. This is a safety issue that requires immediate professional attention — not a DIY inspection.
- Extreme temperature stratification in two-story homes. The 2,500–4,000 sq ft homes in Copper River Ranch and similar 93619 tracts were built with single-zone Lennox systems that can’t overcome physics. Hot air rises, the upstairs master suite bakes at 85–90°F, and the downstairs over-cools. The equipment isn’t necessarily broken; it’s fundamentally mismatched to the house. We routinely solve this with zone additions before recommending full replacement.
- Capacitor and contactor failure from continuous operation. Clovis’s June-through-September heat stretches mean Lennox systems run 16–20 hours daily for months. Run capacitors degrade, contactors pit and weld shut, and the system either won’t start or won’t stop. These are straightforward fixes, but diagnosing them correctly requires distinguishing a $200 capacitor call from a $3,500 compressor failure — something our field experience handles quickly.
- Refrigerant leaks at flare connections and evaporator coils. The thermal expansion and contraction from Clovis’s 40°F winter lows to 110°F summer highs stresses refrigerant line connections. Lennox systems from the 2000s–2010s era particularly show flare joint leaks that drop charge slowly, causing ice-up, poor cooling, and eventual compressor damage if ignored.
Lennox Service in Clovis: What Local Conditions Mean for Your Equipment
Clovis’s northeast 93619 ZIP code has over 15,000 homes built between 1995 and 2010, nearly all with identical single-zone Lennox Merit systems. This density creates predictable simultaneous end-of-life failures, unlike neighboring Fresno’s mixed-vintage stock where we also handle Lennox repair in Fresno. When we get three calls in a week from Copper River Ranch, Loma Vista, or the neighborhoods off Temperance Avenue, it’s not coincidence — it’s the replacement cycle hitting a cohort of systems that were all installed by the same builders during the same boom years.
That concentration shapes how we work. We stock common Lennox G60 heat exchangers and ML14XC1 compressors because we know the demand pattern. We understand the ductwork shortcuts those builders took — flex duct runs that are 20 feet too long, returns sized for 1,800 sq ft crammed into 3,500 sq ft footprints, master bedrooms with no return path at all. And we know the San Joaquin Valley Air Pollution Control District’s Rule 4905 low-NOx furnace requirement, which restricts equipment selection in ways that catch out-of-market contractors unprepared. A Lennox replacement in Clovis isn’t just a swap; it’s navigating local code, local climate, and local construction history simultaneously.
Lennox Models & Products We Service in Clovis
We work on the full Lennox residential and light commercial line, with particular depth on the systems that dominate Clovis’s housing stock. The Lennox Merit ML14XC1 single-stage condenser appears in probably half the 93619 calls we take — we know its failure signatures, its compatible scroll compressor replacements, and when a repair is throwing good money at equipment that won’t survive another summer. The Lennox G60 gas furnace, common in pre-2010 builds, requires careful heat exchanger inspection and low-NOx replacement planning under SJVAPCD rules. For homeowners ready to upgrade, the Lennox Signature XC20 variable-speed heat pump paired with ComfortSense zoning solves the hot-upstairs problem that single-zone systems can’t touch.
Our parts strategy is simple: OEM Lennox compressors, heat exchangers, and control boards for compatibility and warranty support; quality aftermarket capacitors, contactors, and sensors that often outlast the original spec. We keep common Lennox components stocked locally for same-day Clovis turnaround, because nobody wants to wait three days for a capacitor when it’s 108°F outside.
Lennox Service Pricing in Clovis
| Service | Price Range |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation / Replacement | $3,500–$7,500 |
| Tune-Up & Inspection | $80–$200 |
What drives cost? Compressor replacement on an ML14XC1 runs toward the high end of AC repair; a capacitor or contactor swap sits at the low end. Full AC replacement in Clovis’s large two-story homes trends higher because proper sizing, duct remediation, and potential zoning work add scope. Our free estimates include load calculation, duct inspection, and honest assessment of repair-versus-replace — no pressure, just the numbers. Call (844) 875-9451 to schedule yours.

FAQs — Lennox HVAC in Clovis
Your compressor is likely drawing excessive amperage due to high head pressure, dirty condenser coils, or failing capacitor support. In Clovis’s heat, these problems compound quickly. Don’t keep resetting the breaker — the compressor can suffer terminal damage. Call (844) 875-9451 for same-day diagnosis; estimates are free.
Your ductwork and zoning, not the equipment itself, are the problem. Single-zone systems in 3,000+ sq ft two-story homes can’t overcome stack effect and insufficient return paths. We often add a Lennox zoning system or ductless mini-split to the upper floor before replacing functional equipment, a strategy that works equally well for Lennox repair in Fowler. If I wouldn’t put it in my own house, I’m not recommending it for yours.
Yes. The San Joaquin Valley Air Pollution Control District’s Rule 4905 mandates low-NOx furnaces throughout the region. Not all Lennox models qualify, and contractors unfamiliar with SJVAPCD requirements can quote equipment that won’t pass final inspection. We verify low-NOx compliance on every Lennox furnace replacement in Clovis.
Yes — banging on startup often indicates delayed ignition or cracked heat exchanger expansion noise. Both are safety concerns. The G60’s secondary heat exchanger is particularly vulnerable to condensate damage from short-cycling in mild Clovis winters. Turn the system off and call for inspection; don’t attempt heat exchanger diagnosis yourself. Call (844) 875-9451 for priority service.
Often yes, and it’s frequently the most cost-effective solution for the hot-upstairs problem in Clovis’s two-story homes. A Lennox mini-split or compatible ductless system serving the master suite and upper hallway can drop temperatures 10–15°F for a fraction of full replacement cost, an approach we also use for Lennox in Sanger. We evaluate your existing system’s condition, your electrical panel capacity, and your long-term plans before recommending this path. Call (844) 875-9451 to discuss your specific layout.
