Lennox HVAC in Clovis, CA | Stonegate Heating & Air California
We provide independent Lennox service across Clovis’s 93611, 93612, 93613, and 93619 ZIP codes, from emergency repairs on 20-year-old Merit series units to full replacements with current Elite and Signature systems, and also handle Lennox in Sanger. What makes our Lennox work here different is simple: we’ve spent 16 years watching these specific machines fail in Clovis’s specific conditions, and we know which problems mean repair and which mean replacement before we even open the panel.

Why Clovis Residents Choose Us for Lennox Service
Jason Trent, our owner and field supervisor, grew up in the San Fernando Valley and spent enough summers without reliable AC to know exactly what 110°F inside a house feels like. He took HVAC coursework at Los Angeles Trade-Technical College before building Stonegate Heating & Air California into a 16-year operation with nearly 500 verified reviews at a 4.7-star average. Jason still shows up on the bigger jobs himself because he doesn’t trust a final walkthrough to anyone else.
That matters for Lennox owners in Clovis because these systems have quirks. The Merit 13ACD evaporator coils fail differently than Carrier or Trane coils. The Signature variable-speed boards throw codes that look like refrigerant problems but aren’t. We’ve diagnosed enough of them to know the difference without guessing. We carry OEM Lennox parts for compressors, TXVs, and control boards, plus quality aftermarket equivalents for capacitors and contactors that save you 30–50% over dealer pricing. And because we service nine major brands, not just Lennox, we won’t try to sell you a new system when a honest repair makes more sense.
Common Lennox HVAC Problems We Solve in Clovis
- Compressor oil-return failures on out-of-level condenser pads. The decomposed granite soil in 93619’s hillside tracts settles unevenly, tilting condenser units just enough to trap oil in the compressor sump. We see this on 10–15 year old Elite 16ACX systems in the Harlan Ranch area. Leveling the pad and adding an oil-return kit usually saves the compressor.
- Evaporator coil micro-leaks on mid-2000s Merit 13ACD units. Clovis’s unconditioned attics hit 140–155°F in July, and agricultural dust from nearby almond orchards accelerates fin corrosion. The combination creates pinhole leaks that bleed refrigerant slowly. We’ve replaced dozens of these coils in Harlan Ranch alone, often on houses built within months of each other.
- Blower motor and control board failures from sustained high-amp operation. When it’s 108°F for a week straight, your Lennox runs near-continuously. Voltage sags on hot summer afternoons push amperage higher than design spec, cooking bearings and capacitors. We stock both OEM and aftermarket motors for same-day replacement.
- Refrigerant line degradation at service-valve connections. Tule fog season brings weeks of 40°F mornings and 65°F afternoons. That thermal cycling, plus vibration from blowers mounted in unconditioned attics, cracks flare nuts and valve stems. We catch these with electronic leak detection before they empty the system.
- High-pressure switch trips on Signature SL28XCV units during heatwaves. The variable-speed compressor ramps to full capacity automatically, but if the condenser coil is even partially clogged with cottonwood or orchard dust, head pressure spikes. We clean with foaming cleaner and check charge by weight, not guesswork.
Lennox Service in Clovis: What Local Conditions Mean for Your Equipment
Because Clovis was built almost entirely in two master-planned waves, 1992–2000 and 2004–2009, entire neighborhoods share identical construction dates and original equipment. In Harlan Ranch and similar 93619 communities, we regularly replace multiple Lennox Merit 13ACD units on the same cul-de-sac within a single summer. The entire neighborhood was commissioned within an 18-month window, so every system hits the same failure mode at the same age. Fresno’s housing stock is more staggered; you won’t see this synchronized pattern with Lennox repair in Fresno.
That clustering shapes how we work. We keep extra Merit-series evaporator coils and EL16XC1 condensers staged during July and August. When one house on Pinot Noir Way fails, we know to ask neighbors about their unit’s age. Last August, we got a call on a 2007 Lennox Merit 13ACD that had lost its charge. We found a micro-leak on the evaporator coil, a known failure on that model series. Since the unit was 16 years old and the compressor had already been running hard during the 108°F heatwave, we quoted a replacement with an EL16XC1 and a 4-inch media cabinet. The neighbor across the street had the same unit fail two weeks later; we replaced both on the same block using one truckload of equipment.
The San Joaquin Valley’s chronically poor air quality, among the worst PM2.5 and ozone levels in the nation, means Clovis homeowners are unusually motivated to upgrade filtration when they replace equipment. We spec MERV 13 or 4-inch media cabinets on nearly every install here. It’s not an upsell; it’s a necessity.
Lennox Models & Products We Service in Clovis
We work on the full Lennox residential lineup, from legacy Merit 13ACD units still running in 1990s tract homes to current Signature SL28XCV variable-speed systems. The Elite 16ACX and EL180UHNE furnace are common in 2004–2009 builds. We stock OEM Lennox control boards, TXVs, and compressors, plus aftermarket capacitors and contactors that meet or exceed OEM specs. For Lennox sales & service questions about newer equipment, we can source factory parts within 24 hours. Our techs are trained on Lennox’s error-code diagnostics, so we’re not guessing when the board flashes a two-digit code.

FAQs — Lennox HVAC in Clovis
Replace it. At 18 years, even a successful coil replacement leaves you with an R-22 system that’s expensive to recharge and inefficient to run during Clovis’s 105–112°F summers. The compressor is also near end-of-life. We typically recommend a new EL16XC1 with a media filter cabinet. Call (855) 467-1888 for a free replacement estimate.
A 4-inch media filter with MERV 11–13 rating, not a 1-inch fiberglass throwaway. The agricultural dust and PM2.5 in eastern Clovis, especially in 93619, overwhelms standard filters in weeks. We install media cabinets on most replacements here.
Yes. The City of Clovis requires a mechanical permit for any furnace or air handler replacement. We pull permits on every job and schedule inspections so you don’t have to coordinate with the city yourself.
Most likely a dirty condenser coil, overcharge, or failing condenser fan motor. The extreme heat already pushes head pressure to the edge; any additional restriction sends it over. We clean, check charge by weight, and test amp draw. Call (855) 467-1888 if it’s happening repeatedly.
No. Short-cycling in mild weather usually means an oversized system, a failing thermostat, or a refrigerant charge issue. 2008 Lennox heat pumps in that neighborhood are right at the age where TXVs start sticking. We can diagnose it properly and discuss whether Heat Pump & Mini Split in Clovis options make sense for your home.
