This page is for Alpharetta homeowners with a Trane furnace that isn’t heating right. You’ll find the failure patterns we see most often, what repairs actually cost, and the exact process we follow. No brand fluff. Just what we’ve learned fixing these units in Alpharetta homes for years.
How Trane Products Fail – and How We Fix Them
Trane makes solid furnaces. The XR and XV series units we see across Alpharetta are built to last 15 to 20 years if maintained. But they fail in predictable ways. Here are the five we run most often.
- Ignitor failure on XR80 and XR90 models. Trane uses a silicon nitride hot surface ignitor that gets brittle with age. What starts as an intermittent no-heat call in early winter often ends up being a cracked ignitor by January. The fix is straightforward: replace the ignitor, verify the flame sensor reading, and test cycle the unit. The part cost is typically $80 – $150 of the total repair bill.
- Pressure switch lockouts on XV95 and XV80 communicating systems. Trane’s two-stage and modulating furnaces use pressure switches to confirm proper venting. In Alpharetta, where we get heavy pine pollen and oak litter in the fall, the condensate drain or the vent pipe gets blocked, and the pressure switch trips. The furnace will attempt ignition, fail, and lock out. We clean the trap, clear the vent, and verify the pressure switch operation with a manometer before resetting. That’s the difference between a real repair and a call that repeats in two weeks.
- Inducer motor bearing noise on XR series. When an inducer motor starts rattling or whining, it’s almost always bearing wear. Left alone, it seizes, and the furnace won’t establish draft, so the unit won’t fire at all. We replace the inducer assembly or motor, depending on model year and parts availability, and the repair usually lands between $250 and $450.
- Heat exchanger stress cracks on 15- to 20-year-old XE and XL units. Trane heat exchangers use tubular steel with crimped joints. On older units we see cracks at the crimp points. This isn’t a parts-swap situation. A cracked heat exchanger is a safety issue and a code issue. When we find one, we shut the furnace down, show you the exact crack with a camera scope, and give you a straight repair-versus-replace price. Some XE and XL heat exchangers are still under Trane’s limited lifetime warranty, but the labor to replace one usually starts around $600, which gets you into new-furnace territory.
- Error code persistence on XV communicating systems after a power surge. Alpharetta gets its share of summer thunderstorms, and communication boards on the XV line don’t always recover cleanly after a surge. The furnace may throw an LED code or the thermostat loses communication. We reset the system, verify the board isn’t damaged, and recommend surge protection for the furnace circuit if it becomes a repeat issue.

Our Trane Furnace Repair Process
Every Trane job we run in Alpharetta follows the same sequence. It’s the same process Marco Benitez has used since he started turning wrenches in Los Angeles and then moved it to Georgia. Five steps, no shortcuts.
- 1
You call, a person answers. No voicemail queue. You tell us what the furnace is doing, and we give you a straight arrival window, not a four-hour maybe.
- 2
Diagnosis, not guesswork. The tech arrives, checks the thermostat setting, the air filter, the condensate drain, and then runs through the Trane diagnostic sequence for your specific series. On XV units, we pull the error code history, not just the current state.
- 3
Written price before any wrench turns. We show you the diagnosis, explain exactly what failed, and give you the repair cost in writing before work starts. You decide. No pressure, no surcharge for the diagnosis.
- 4
Repair with the right part. If OEM Trane parts are the warranty-safe choice, we use them. If a quality aftermarket part with equal reliability makes more sense for an out-of-warranty unit, we tell you that and let you choose. The decision is yours, with our honest recommendation.
- 5
Test, clean, and guarantee. We run the furnace through full cycles, verify the temperature rise across the heat exchanger, check for gas or exhaust leaks, clean the work area, and hand you a written one-year repair guarantee. If it fails in that window, we return at no charge.

AfterWhat Trane Furnace Repair Costs in Alpharetta

- Ignitor replacement: $150 – $250
- Pressure switch or flame sensor: $120 – $190
- Inducer motor replacement: $300 – $550
- Gas valve replacement: $250 – $450
- Blower motor replacement: $350 – $650
- Heat exchanger replacement (if under warranty): $600 – $700 labor, which often means it’s time to look at a new furnace
The price moves based on which Trane series you have, how old it is, and whether OEM parts are the right call. Every quote is written before we start, and every diagnosis is free with repair. If the furnace is over 15 years old and the repair is creeping past $700, we’ll tell you that plainly and give you replacement numbers to compare.

FAQs
No. Repairs performed by a qualified contractor using proper OEM or equivalent parts do not void a Trane warranty. As an independent Trane service provider, we follow Trane specifications on warranty-eligible repairs and document everything. If your unit is still under warranty, we handle the parts claim paperwork on your behalf.
Most Trane furnace repair calls in Alpharetta are scheduled same-day or next-day, and we offer 24/7 emergency service with a live person answering the phone at (229) 537-2086. The exact window depends on call volume and part availability, but we tell you the time frame honestly before we dispatch.
If the repair cost is under $700 and the unit is less than 12 years old, repair usually makes sense. If the heat exchanger is cracked or the repair exceeds roughly half the cost of a new furnace, we’ll walk you through the replacement math. Trane XV and XR furnaces can run 15 to 20 years with proper maintenance, but once a major component fails on an aging unit, replacement often wins on total cost.
We use OEM Trane parts when the unit is under warranty or when OEM is the clear quality choice. For out-of-warranty units where a quality aftermarket part provides equal reliability at a meaningfully lower price, we’ll show you both options in writing and let you decide.
The two most common causes on Trane XR and XV series furnaces in Alpharetta are a failing flame sensor and a blocked condensate drain that trips the pressure switch. A failing flame sensor sends a weak signal and the gas valve shuts off seconds after ignition. A blocked drain restricts venting and triggers a lockout. Both are repairable same-day in most cases. Call (229) 537-2086 and tell us the exact unit behavior, and we’ll tell you what it likely needs.
