How Lennox Products Fail – and How We Fix Them
Lennox builds a solid furnace, but every manufacturer has patterns. Here are the five we see most often on Lennox systems in Henderson homes.
- Ignitor failure on Merit and Elite series units. Lennox furnaces from the mid-2000s through the mid-2010s shipped with silicon nitride ignitors that get brittle with age. The symptom is usually a furnace that clicks, the inducer motor runs, but no flame ever lights. We replace these with updated OEM ignitors that handle the cycling better. This is the single most common Lennox repair we do, and it’s typically a $200 to $350 job.
- Pressure switch faults on condensing models. The Elite EL296 and Signature SLP98 lines are high-efficiency condensing furnaces. Their pressure switches read airflow through the collector box and exhaust. In Henderson, where dust is a daily reality, the port on the collector box clogs and the switch reads a false negative. The furnace locks out. The fix is cleaning the port and the switch tubing, not necessarily replacing the switch itself. We check both before quoting a part.
- Flame sensor carbon buildup across all Lennox lines. This is a maintenance issue that becomes a repair issue. Lennox flame sensors collect a carbon layer over time, and when that layer gets thick enough, the sensor can’t confirm the flame is lit. The furnace fires up and shuts down repeatedly. The fix is a cleaning and resurfacing of the sensor, a $150 to $250 job depending on accessibility. We also check the burner alignment while we’re in there because a misaligned burner produces the same symptom.
- Heat exchanger issues on older Pulse and G-series units. Lennox Pulse furnaces have been out of production since the late 1990s, but plenty are still running in Henderson’s older neighborhoods around Green Valley and Whitney Ranch. When a heat exchanger develops a crack on those units, the smell of aldehydes is usually the first sign. We inspect with a camera and certify the part before quoting. If it’s cracked, repair is not a sensible option on a furnace that old. We’ll give you the replacement number straight.
- Variable-speed blower motor failure on Signature units. The SLP98V and EL296V use ECM blower motors. They fail differently than the fixed-speed motors in Merit furnaces. You’ll hear a whining or clicking from the blower compartment, or the fan won’t ramp up properly. We test the motor and module separately, because the module often fails while the motor body is fine. That’s a $400 to $700 repair versus a full motor, which can push past $1,100. We only quote the part that’s actually dead.

Our Lennox Furnace Repair Process
You’ll know the price before any work starts. That’s not a slogan, it’s the Garrison Standard we’ve operated under since 2003. Here’s how a Lennox repair call goes at Dalton Heating & Air Henderson.
- 1
Call comes in, live person answers. You talk to a human, not a voicemail tree. We ask what the furnace is doing or not doing, and we schedule a window that we actually hit.
- 2
Technician arrives, backgrounded and uniformed. Marco Benitez and his crew wear Dalton gear and shoe covers at your door. You know who’s coming before they ring the bell.
- 3
Diagnostic first, written price second. The tech opens the cabinet, runs the fault codes, and tests the suspect component. Then you get the repair cost in writing before any tools come out. “If the price surprises you, something went wrong before I even opened my toolbox.”
- 4
Parts decision, OEM vs quality aftermarket. For warranty-sensitive Lennox repairs, we use OEM parts. For out-of-warranty ignitors, sensors, and pressure switches, we’ll offer a quality aftermarket option when it performs equal to or better than the factory part. You decide with the prices in front of you.
- 5
Repair, then load test. We don’t just replace the part and leave. The furnace runs through a full cycle, then it runs again. We check the temperature rise, gas pressure, and flame pattern. If it’s a condensing unit, we check the drain.
- 6
Cleanup and the 365-Day Done Right Promise. The work area is left cleaner than we found it. Your repair is guaranteed in writing for a full year. If it fails in that time, we return at no charge. No fine print, no trip fee, no argument.

| Lennox Repair | Typical Price Range |

What moves the price is the part, not our mood. An EL296 gas valve is a different component than an older G-series valve, and we don’t pad the difference. Estimates are free, and if the furnace isn’t worth fixing, we’ll tell you that instead of selling you a patch job. Call (775) 593-7060 for an exact quote.

AfterWhy Henderson Homeowners Call Dalton Heating & Air Henderson for Lennox Work
Lennox equipment has specific engineering choices that a generalist can miss. We see those units every week in Henderson, so the diagnostic goes faster and the repair gets done right the first time. Our techs are factory-trained across nine major brands, including Lennox, Carrier, and Trane, which matters when you have a Lennox furnace paired with a different brand’s condenser or thermostat.
Every repair gets a written price before work starts, a written guarantee for a full year, and a free return visit if the repair fails inside that window. That’s the Garrison Code, and it’s been the standard at every Garrison Partners location since 2003. If we tell you the furnace needs a repair, we stand behind that call for 365 days. No 30-day window, no upgrade fee to get the real guarantee.
FAQs
No. As an independent service provider, we perform repairs that keep your Lennox warranty intact. The Magnuson-Moss Warranty Act protects your right to choose any qualified service provider, and Lennox honors their warranties with independent companies as long as OEM or approved aftermarket parts are used where required. We’ll flag any repair that could touch a warrantied component before we quote it.
In most cases, same day or next morning. We keep ignitors, flame sensors, pressure switches, and common Lennox gas valves stocked on our trucks, so a single visit handles most furnace repairs. Call (775) 593-7060 and a live person will give you the next available window, not a callback time.
If the repair is under $700 and the furnace is under 15 years old, repair usually makes sense. If the heat exchanger is cracked on a Pulse, G-series, or any unit past 18 years, replacement is the honest answer. We’ll give you both numbers: the repair cost and a replacement quote for a properly sized Lennox or alternative system. You decide with accurate information.
Yes, on all warranty-sensitive repairs and whenever the factory part is the better choice. For out-of-warranty ignitors, flame sensors, and pressure switches, we may offer a quality aftermarket option at a lower price, and we’ll tell you the difference in plain terms. The choice is always yours with the prices in writing.
The repaired component and the labor to fix it are covered in writing for a full year. If the same repair fails inside those 365 days, we return at no charge, no trip fee, no parts cost. That’s the 365-Day Done Right Promise, and it’s included on every Lennox furnace repair we do in Henderson.
