How Lennox Products Fail – and How We Fix Them

Lennox builds solid equipment, but every brand has its patterns. After well over a decade of furnace repair in Austin, here’s what we actually see on Lennox units:

• Ignitor failures on the Elite series (EL195, EL296): The silicon nitride ignitor on mid-tier Elite furnaces runs hot and can crack after 8 – 12 years. The symptom is a furnace that hums, the draft inducer spins up, but no flame ever catches. We stock both OEM ignitors and quality aftermarket equivalents, and most ignitor replacements run $150 – $280 parts and labor included.
• Pressure switch faults on the SLP98V: The variable-speed SLP98V is a great furnace, but its condensate lines are narrow. In Austin’s humid winters, algae or dust can clog the condensate trap, which fools the pressure switch into thinking the vent is blocked. The furnace locks out. We clear the trap, verify the switch with a manometer (a gauge that measures gas pressure), and usually have you running again in under an hour for $150 – $250.
• Heat exchanger corrosion on older G26 and G40 units: If your Lennox is 15+ years old and you’re getting a slight smell or the flame looks orange instead of blue, the heat exchanger may have a crack. This is the one repair where we’ll be straight with you: if the exchanger is bad on a unit that old, replacement usually makes more sense than a $600 – $900 patch on a furnace nearing the end of its life.
• Control board failures on the Merit series (ML193, ML296): The Merit line is Lennox’s value tier, and its control boards are sensitive to power surges. After a Central Texas lightning storm, we get calls for dead furnaces where the board shows no LED diagnostic light at all. A replacement board runs $300 – $500 installed, and we keep common Lennox board part numbers on our trucks.
• Gas valve sticking on two-stage units: The two-stage gas valves on Elite and Signature furnaces occasionally stick on low fire, which means the furnace runs but never reaches full heat. That’s why an Austin home feels lukewarm even though the system never shuts off. We clean or replace the valve depending on its condition, usually $200 – $400.

Our Lennox Furnace Repair Process

Here’s how a typical Lennox repair goes at Cold Harbour Heating and Air Austin, from the first call to the final cleanup:

1. 1
   You call, a person answers. Day or night. We ask what the furnace is doing, what you’ve noticed, and whether it’s the original Lennox system or a newer install. That helps us stock the truck right the first time.
2. 2
   We show up in the window we gave you. Not a four-hour arrival span either. Our techs arrive in uniform, introduce themselves, and put on shoe covers before stepping inside.
3. 3
   Diagnosis first, price second. We test the system with the proper meters and gauges, find the actual fault, and then hand you a written price before a single tool comes out of the bag. That price does not change at the door. This is what we call The Kingswell Way, and it’s written down, not just talked about.
4. 4
   Parts decision, made together. If your Lennox needs a part, we tell you the OEM option and any quality aftermarket option if one makes sense. You get the price difference and our honest recommendation. No games.
5. 5
   The repair and the test. We fix the furnace, then run a full heating cycle to verify the flame, the airflow, the safety switches, and the temperature rise across the heat exchanger. We don’t leave until it’s right.
6. 6
   The guarantee, in writing. Every repair gets the 365-Day Done Right Promise. If the same repair fails within a year, we come back and make it right at no charge. It’s on paper before we leave your driveway.
