Trane AC repair in Pasadena typically runs $150 – $650 depending on the failed part, and most jobs are diagnosed and fixed the same day. We’re an independent Trane service provider – not a manufacturer-authorized shop – which means we make repair decisions based on what’s right for your system and your budget, not what a corporate program tells us to do. This page is for Pasadena homeowners with a Trane unit that’s blowing warm air, short-cycling, making noise, or not running at all. Call (626) 657-5344 and you’ll get a live person, a straight answer, and a written price before any work starts.
Every repair includes a full-year written guarantee. If the same part fails within 365 days, we return and fix it at no charge – that’s The Garrison Standard, and we’ve operated under it since 2003.
How Trane Products Fail – and How We Fix Them
- Trane XR14/XR16 – capacitor failure on hot starts. On Pasadena days above 95°, we see the run capacitors in XR-series condensers swell and leak. The unit hums but the fan won’t spin. We test microfarad readings under load, replace with an OEM-spec dual-run capacitor, and verify the compressor starts clean before we leave.
- Trane XL16i/XL18i – thermostatic expansion valve (TXV) sticking. These higher-efficiency lines use a TXV to meter refrigerant. When it sticks, you get poor cooling and higher head pressure. The tell is a frosted line at the evaporator coil with a warm house. We recover refrigerant, replace the TXV, pull a proper vacuum, and recharge to the exact ounce specified on the nameplate.
- Trane XR80/XR90 furnaces with AC coils – condensate drain clogs. In older Pasadena homes, especially bungalows with original duct runs, dust and pet hair accumulate in the evaporator coil and clog the condensate line. We clear the drain, check the float switch, and treat the pan to slow regrowth. Skipping the drain check turns a $200 call into a $1,200 ceiling repair.
- Trane variable-speed air handlers (Hyperion) – ECM blower motor faults. These motors fail differently than standard PSC motors: they throw control-board fault codes rather than just dying. We read the flash codes on the board and test motor windings before condemning the blower. Aftermarket ECM motors exist, but we’ve seen too many fail within a year – on Hyperion units we recommend OEM or a factory-remanufactured unit.
- Trane communicating systems (ComfortLink II) – thermostat losing handshake. If a Trane 900-series thermostat loses communication with the outdoor unit, the compressor may not engage at all – even when the fan runs. We check the low-voltage wiring, re-establish the handshake, and update firmware if needed. This is a repair that gets misdiagnosed as a bad compressor more often than it should.
Styles & brands we work with




Our Trane AC Repair Process
- 1
You call (626) 657-5344. A live person answers – not a voicemail tree. We set an arrival window that works for your schedule.
- 2
We diagnose the unit at your home. Gauges on the manifold, electrical readings at the contactor and capacitor, and a check of the thermostat’s call for cooling. You hear the findings in plain English before any money changes hands.
- 3
You get the written price. The cost of parts, labor, and refrigerant (if needed) goes on paper. That number doesn’t move. Signature phrase from Marco: “You get the price in writing before I touch anything. That’s not a policy – it’s just how this should work.”
- 4
We make the repair. We use Trane OEM parts when they’re the right call, and quality aftermarket replacements when they’re the honest value – and we tell you which we’re doing and why. No silent substitutions.
- 5
We test, verify, and clean up. Delta-T checked across the coil, refrigerant pressures confirmed, drain line cleared, and the work area left the way we found it.
- 6
You walk away with a written guarantee. One year, in writing, covering the repair. If it fails in that time, we come back at no charge.

AfterWhy Pasadena Homeowners Call Dalton Heating & Air Pasadena for Trane Work
Trane builds equipment that lasts, and when it breaks, it deserves a technician who actually knows the equipment – not a guy with a meter and a prayer. Marco Benitez trained in refrigeration and HVAC systems at Los Angeles Trade-Technical College, and he’s spent years turning classroom work into field experience. He and our crew service all nine major residential brands – Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard – so when we walk up to a Trane, we know what it’s supposed to do and what it’s doing instead.
Here’s what that means on a job: we arrive on time, in uniform, background-checked. We quote a flat price in writing before turning a wrench. We do the work by the book under The Garrison Code, and if it’s not done right, the 365-Day Done Right Promise means we make it right – for a full year, not a 30-day window. As an independent Trane service provider, we’re not tied to a factory program that pushes replacement over repair. We’re tied to getting your system cooling again.
FAQs
No. As long as the repair is done by a licensed HVAC contractor using compatible parts, your Trane warranty remains intact. We’re an independent Trane service provider – not warranty-affiliated – but we document every repair properly so your warranty claim stays clean. We’ll also tell you upfront if a repair is covered under warranty before you pay for anything.
Most Trane repairs are completed same-day. Capacitors, contactors, and drain clogs are stocked on our trucks, and we cover Pasadena daily. Compressor failures or ECM blower motor issues may need a parts order, which adds one to three business days depending on local supply. Call (626) 657-5344 and we’ll give you a straight answer on timing for your specific issue.
For systems under 10 years old, repair is usually the right call – especially for mechanical parts like capacitors, contactors, or fan motors. For Trane units over 12 years old with a failed compressor or leaking evaporator coil, replacement often pencils out better long-term. We’ll give you the repair cost and an honest assessment of remaining lifespan. No pressure to replace – this is a free estimate, not a sales call.
Most common Trane parts – capacitors, contactors, thermostats, fan motors – are on our trucks. Specialty items like OEM ECM blowers or TXV valves for XL-series units are available from local supply houses same-day or next-day. If a part is backordered, we’ll tell you before you pay a diagnostic fee.
Yes. We service all nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If you have a mixed system – say a Trane outdoor unit paired with a Carrier air handler – we can service both without calling two companies. Call (626) 657-5344 to get a live person and a written diagnostic quote.
