Carrier furnace repair in Pasadena typically runs $150 – $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, not a factory-authorized dealer, which means we make repair decisions based on what’s actually best for your system and your budget, not on what the manufacturer pushes. You get a written price before any work starts, a written guarantee on the repair for a full year, and a real person on the phone 24/7 at (626) 657-5344.
If you own a Carrier furnace in Pasadena and it’s blowing cold air, cycling erratically, or making a sound it never made before, this page will tell you what’s actually going wrong, what it should cost to fix, and how we handle the job from first call to final test.
How Carrier Products Fail – and How We Fix Them
- Infinity and Performance series: failed hot surface ignitors. Hot surface ignitors are the glowing element that lights your gas. On Carrier Infinity and Performance series furnaces, these are designed to ignite quickly, which means they run hot and eventually crack. The symptom is usually a furnace that tries to start, you hear the induced draft motor spin up, then nothing. No flame. We replace the ignitor with either an OEM Carrier part or a high-quality Nitride-style aftermarket unit, and we’ll tell you the difference before we order anything.
- Comfort series: dirty flame sensors. The flame sensor is a thin metal rod that confirms the burners actually lit. On Carrier Comfort series furnaces, especially in older Pasadena homes where dust gets pulled into the return air, these sensors collect a layer of oxidation and start sending a false “no flame” reading. The furnace lights for 3 to 5 seconds, then shuts off, and repeats. This is frequently a cleaning job we’ll handle during a tune-up, but if the sensor is too far gone, replacement is inexpensive.
- Infinity series: failing gas valves due to pressure issues. Carrier Infinity furnaces use modulating gas valves that adjust flame output in small increments. When gas pressure from the street is inconsistent, or when the internal diaphragm starts to harden after years of cycling, the valve can fail to open fully or fail to close completely. We test inlet and outlet gas pressure with a manometer, not by guesswork, and we replace the valve when it’s not holding spec. We never tell a customer to live with an intermittent flame.
- Performance and Comfort series: blower motor capacitor failures. The blower motor pushes heated air through your ducts. On older Carrier Performance and Comfort series furnaces, the run capacitor that starts the blower motor degrades over time, particularly in Pasadena attics where heat accelerates electrical component wear. The classic symptom is a furnace that produces heat but barely moves air, or a blower that hums without turning. We stock common capacitor values on our trucks and can usually restore full airflow the same visit.
- Infinity series: heat exchanger stress in old units. Heat exchangers on any furnace are the metal chamber where combustion happens. On early Infinity series units, especially those from the mid-2000s that have been running hard through Pasadena’s winter mornings, microscopic cracks can develop at weld points. This is the one repair where we’ll tell you plainly: a cracked heat exchanger on a 15-plus-year-old furnace usually means replacement, not patchwork. We’ll show you the crack on our inspection camera, not describe it from memory.

Our Carrier Furnace Repair Process
- 1
You call, a human answers. We answer 24/7 at (626) 657-5344. No call center, no voicemail queue. You tell us what the furnace is doing or not doing, and we’ll give you a straight arrival window.
- 2
We show up inside the window. The Garrison Code requires it. We’re not late because we don’t schedule in a way that makes lateness likely. The truck arrives, the tech is background-checked and in uniform.
- 3
Diagnosis, with a written price. We run through the sequence of operation: thermostat call, induced draft, ignitor, gas valve, flame sensor, blower. We find the problem. Then Marco Benitez’s rule applies: you get the price in writing before anything is touched. Not after. Not “we’ll see.” Written.
- 4
The repair, by the book. We use OEM Carrier parts when the warranty or the system’s age calls for it, and quality aftermarket parts when we can honestly say they’ll perform as well for less. We’ll explain which one we’re recommending and why, in plain English.
- 5
We test the full cycle. We don’t just fix the broken part and leave. We run the furnace through 3 full heat cycles, check temperature rise across the system, verify the flue is drafting correctly, and make sure nothing else is about to fail.
- 6
Cleanup and a written guarantee. We leave the space cleaner than we found it, and you get the repair guaranteed in writing for a full year. If it fails in that time, we return at no charge.

Why Pasadena Homeowners Call Dalton Heating & Air Pasadena for Carrier Work
We fix what’s broken and we stand behind it in writing. The Garrison Standard, which we’ve followed since 2003, means every repair carries a 365-Day Done Right Promise: if it’s not done right, we make it right. That’s not a warranty with fine print. It’s a full year of coverage on every job, and a free second visit if the repair fails within that period.
Our technicians are factory-trained on Carrier and eight other major residential brands: Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters when you have a Carrier furnace and we’re cross-referencing motor mounts or control board voltages against comparable Trane and Lennox units. The multi-brand experience means we don’t guess when a Carrier system acts like a Carrier system.
FAQs
We answer the phone 24/7 and can usually have a technician at your Pasadena home the same day, often within a few hours, depending on call volume. The exact window is given when you call. Call (626) 657-5344 now for a live answer and a straight arrival time.
We use OEM Carrier parts whenever the manufacturer warranty calls for them or when the system’s age and condition make OEM the honest best choice. When a quality aftermarket part will perform as well and save you real money, we’ll tell you that, with the price difference spelled out before anything is ordered. You always get the decision in writing.
We install and repair using OEM Carrier parts when warranty coverage applies to the part. As an independent Carrier service provider, we can’t file warranty claims as a dealer would, but we’ll provide the documentation and part details you need to file a parts warranty claim directly with Carrier or through the installing contractor. The repair itself is guaranteed in writing for a year by us, regardless of Carrier’s warranty.
If your Carrier furnace is under 12 years old and the repair is a single part like an ignitor, gas valve, or capacitor, repair is almost always the right call. If the heat exchanger is cracked, or if the unit is over 15 years old and you’re facing a second major repair within two years, replacement starts to make more financial sense. We’ll show you the numbers both ways, and when replacement is the honest answer, we’ll say so plainly.
No. Dalton Heating & Air Pasadena does not charge an overtime rate for nights or weekends. The price is the price, it’s in writing before work starts, and it doesn’t change at the invoice. Call (626) 657-5344 any time.
