Carrier furnace repair in San Antonio typically runs $150 to $700 depending on the part that failed, and most jobs are completed the same day we diagnose them. We’re an independent Carrier service provider, which means we fix your furnace without being tied to Carrier’s corporate pricing or parts pipeline. If your Carrier furnace is acting up, call (903) 623-6784 and you’ll get a real person, a straight answer, and a written price before any work starts.
This page is for homeowners in San Antonio who own a Carrier furnace, need it fixed, and want to know exactly what they’re dealing with before anyone shows up at the door. No jargon, no mystery pricing, no runaround.
How Carrier Products Fail – and How We Fix Them
- Infinity and Performance series pressure switch faults. Carrier’s higher-end Infinity and Performance 96 models are notorious for throwing pressure switch codes when the condensate drain backs up. In San Antonio, the real culprit is often the humid air we run for months. The fix is rarely the switch itself. We clean the trap, clear the drain line, and verify the inducer motor is pulling proper draft before replacing anything. That saves you money.
- Comfort series hot surface ignitor failures. The Comfort 92 and Comfort 95 lines use silicon nitride ignitors that get brittle after three to five years of cycling. We see them crack most often in older San Antonio homes where the furnace sits in a dusty attic or utility closet. We carry OEM Carrier ignitors and quality aftermarket equivalents, and we’ll show you the old part before we install the new one.
- Infinity communicating control board issues. The Infinity’s communicating thermostat and board are smart, but when the board fails, you lose everything: heat, diagnostics, even the ability to read error codes. These boards cost more than standard controls. Before you spend $600 or more on a board, we bench-test it so you’re not replacing a part that wasn’t bad.
- Heat exchanger concerns on 90%+ units. Carrier’s high-efficiency condensing furnaces have secondary heat exchangers that can clog or corrode over years of San Antonio’s mineral-heavy condensate. This is the job where you want a tech who knows what to look for. We inspect with a camera and give you an honest repair-or-replace recommendation. If the exchanger is cracked or the condensate has eaten through, we tell you straight, with numbers to back it up.
- Blower motor failures across all lines. From the base Comfort 80 to the top-end Infinity 98, the ECM blower motors can fail after years of pushing air through San Antonio dust. A failing motor often hums or runs at odd speeds before it quits. We test the motor and module separately because sometimes the module is the only bad part, and that’s a cheaper fix than a full motor replacement.

FAQs
In most cases, yes. If the failed part is something we carry on the truck, like an ignitor, flame sensor, or pressure switch, we’ll have your furnace running the same day we diagnose it. If it’s a less common part, like a Carrier Infinity control board, we can usually source it from a San Antonio supplier within a day or two. Call (903) 623-6784 and we’ll tell you what’s realistic for your specific model.
No. As long as the repair is done by a licensed HVAC contractor using proper parts, your Carrier factory warranty remains intact. We’re an independent Carrier service provider, which means we’re not tied to Carrier’s corporate pricing, but we perform warranty-safe repairs and can often handle the paperwork if a covered part needs replacement.
If the repair is under $500 and your furnace is under ten years old, repair usually makes sense. If you’re looking at a heat exchanger failure on a 15-year-old Carrier, or multiple failures piling up, replacement may be the smarter money. We’ll give you real numbers for both paths and let you decide. No pressure, just straight math.
We use OEM Carrier parts when they’re available and make sense for the job. But not every repair needs OEM. A quality aftermarket ignitor or pressure switch can perform just as well and save you money. We’ll show you the part, explain the difference, and let you choose.
We staff for same-day and next-day service across San Antonio, including Alamo Heights, Stone Oak, the Pearl District, and surrounding areas. You’ll get a live arrival time when you book, so you’re not waiting around on a four-hour window. If it’s cold and your furnace is down, say so when you call and we’ll prioritize you.
