Rheem furnace repair in Pasadena typically costs $150 – $700 depending on the part that failed, with most jobs landing between $250 and $450. We’re an independent Rheem service provider, not a factory warranty center, so we diagnose the actual fault and give you the price in writing before we touch anything. Same-day visits are available most days from November through February, when Pasadena mornings drop into the 40s and a dead furnace stops being an inconvenience and starts being a cold night.
If you own a Rheem and it’s blowing cold air, short-cycling, or throwing an error code, this page covers what’s probably wrong, what it’ll cost, and who’s showing up. Call (626) 657-5344 for a free estimate. The person who answers will be a real human, not a queue.
Key Takeaways:
- Most Rheem furnace repairs in Pasadena run $150 – $700, with no overtime charge and a written price before work starts.
- We service every Rheem furnace line commonly installed in Pasadena: Classic, Classic Plus, Prestige, and older Rheem 90+ units from the mid-1990s.
- Every repair is guaranteed in writing for a full year. If it fails within that time, we come back at no charge.
- We’re the Rheem-focused team within Dalton Heating & Air Pasadena, and we also service Carrier, Trane, and Lennox furnaces when a household runs mixed brands.
How Rheem Products Fail – and How We Fix Them
Rheem builds solid furnaces, but every line has habits. Here’s what we actually see in Pasadena homes:
- Prestige series (RGRA/RGRB, 90%+ AFUE): flame sensor corrosion. The Prestige line’s burner box runs tighter than older models, which can trap combustion byproducts and coat the flame sensor faster than you’d expect. The symptom is a furnace that lights for three seconds, then shuts off. We clean the sensor with a proper abrasive, test microamp signal, and if it won’t hold spec after cleaning, we replace it with an OEM Rheem sensor. This is a $150 – $250 repair on most Pasadena visits.
- Classic series (R801/R802, 80% AFUE): hot surface ignitor cracking. The Classic’s nitride ignitor gets brittle after six to eight years, especially in Pasadena’s temperature swing between January nights and forced-air cycling. The furnace tries to ignite, you hear the gas valve click, and nothing happens. We swap in an OEM ignitor – aftermarket silicon-carbide versions fail early and aren’t worth the $40 savings. Typical cost: $200 – $300.
- Classic Plus series (R96/R97, high-efficiency condensing): pressure switch trips on blocked drains. Pasadena’s hard water leaves mineral deposits in the condensate trap and drain lines of condensing Rheem furnaces. The pressure switch opens, the furnace locks out, and the board flashes a code most homeowners read as a bigger problem than it is. We flush the trap, clear the drain, and verify the inducer is pulling proper inches of water column before calling it done. If the switch itself is dead, it’s a $175 – $275 replacement.
- Older Rheem 90+ units (installed 1995 – 2005): control board capacitor failure. These units are getting to the age where the integrated furnace control boards start losing capacitors. Symptoms are random lockouts, error codes that change each cycle, and intermittent blower operation. We test voltage at the board and replace with OEM Rheem boards when available. On some 25-year-old units we’ll have an honest conversation about whether the repair makes sense versus replacing the furnace.
- All Rheem lines: blower motor bearings. Pasadena homes with original duct systems often run restrictive static pressure, which puts extra load on the blower motor. The first sign is a whine or rumble when the fan ramps up. We check the capacitor first, then the bearings. A replacement blower motor runs $300 – $550 depending on whether it’s the ECM or PSC style.

Our Rheem Furnace Repair Process
- 1
You call, a person answers. We take the model number, the symptoms, and your Pasadena neighborhood. No callback window.
- 2
We arrive inside the two-hour appointment window. Background-checked, uniformed technician. You’ll know the name of the person coming before they ring the bell.
- 3
Diagnosis first, price second. We test the ignitor, flame sensor, pressure switch, control board, and gas valve in that order – the sequence Rheem uses to light. Then you get a written price for the exact part and labor. You approve it before anything is unbolted.
- 4
Parts policy. For Rheem furnaces, we use OEM Rheem parts whenever the unit is under warranty or within its serviceable life. For out-of-production parts, we use quality aftermarket components only when OEM is discontinued and we can verify the specs match.
- 5
The repair and the test. We replace the part, then run a full cycle test – ignition, flame signal, safety switches, blower ramp. If it doesn’t hold, we don’t call it fixed.
- 6
Cleanup and the written guarantee. We leave the furnace area cleaner than we found it. You get a written guarantee on the repair for one full year. If it fails in that time, we return at no charge. That’s the Garrison Standard, and it’s not optional.

AfterWhat Rheem Furnace Repair Costs in Pasadena
Here’s the honest range for the Rheem furnace repairs we do most often in Pasadena. Every price below is a written quote, not a starting point that grows by the time we’re at the invoice.
- Flame sensor cleaning/replacement: $150 – $250
- Hot surface ignitor replacement: $200 – $300
- Pressure switch replacement: $175 – $275
- Gas valve replacement: $350 – $550
- Blower motor replacement: $300 – $550 (ECM motors run higher)
- Heat exchanger replacement: $550 – $700 if the unit is still worth repairing
What moves the price is the part, not our mood. Labor is a fixed diagnosis plus a fixed install, and we don’t add overtime charges for evening or weekend calls in Pasadena during the heating season. If the heat exchanger is cracked on a 20-year-old furnace, we’ll tell you the repair number and the replacement number side by side, then let you decide. Call (626) 657-5344 for an exact quote. Estimates are free.
Why Pasadena Homeowners Call Dalton Heating & Air Pasadena for Rheem Work
We’re the crew who shows up when someone else didn’t. Marco Benitez, owner and lead technician, trained at Los Angeles Trade-Technical College and has been working on Pasadena furnaces long enough to know that a Rheem Classic in a Bungalow Heaven craftsman behaves differently than a Rheem Prestige in a 2005 tract home. Different ductwork, different static pressure, different failure patterns. He quotes the job the same way either way.
Every repair includes the 365-Day Done Right Promise: if the work doesn’t hold for a full year, we return at no charge. You get the price in writing before anything is taken apart. The technician arrives in uniform, background-checked, and inside the window we set. And because we service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, we’re not going to invent problems just because Rheem is the only brand we can bill.
Frequently Asked Questions About Rheem Furnace Repair in Pasadena
No. Using an independent service provider never voids a Rheem warranty, as long as the repair itself is done correctly and the parts used meet or exceed spec. We use OEM Rheem parts on warranty-covered units and document the work so you have a paper trail if you ever file a claim. We’re not a Rheem-authorized service provider, but we follow the same repair procedures Rheem publishes for every model line.
Same-day visits are available most days, and during a cold snap we prioritize no-heat calls across Pasadena, Altadena, South Pasadena, and San Marino. Call before noon and we can usually have a technician at your door that afternoon. Calls after 6 p.m. are handled on a next-morning schedule unless it’s an emergency and a technician is already in your area.
If your Rheem furnace is under 12 years old and the repair is under $500, repair almost always makes sense. If it’s over 18 years old and the heat exchanger is cracked, replacement usually wins on both cost and safety – a new heat exchanger on an old Rheem 90+ can run $700, and you’re still left with a furnace that has other aging parts. We’ll show you both numbers and make a recommendation based on what we’d do in our own homes.
We stock the most common Rheem failure components on our trucks: flame sensors, hot surface ignitors, pressure switches, and capacitors for Classic, Classic Plus, and Prestige lines. Less common parts like control boards or gas valves are sourced from local Pasadena-area supply houses, usually same day. If a part has to be ordered, we’ll tell you that before we leave and give you a written estimate with a firm install date.
It means the repair is covered in writing for one full year from the date of service. If the same part fails or the same symptom returns within 365 days, we come back at no charge – no diagnostic fee, no parts fee, no labor fee. You get the guarantee in writing on every Rheem furnace repair we do in Pasadena. It’s not an upgrade, not a warranty you have to register for, not a promise we hedge. You get the price in writing before we touch anything. That’s not a policy – it’s just how this should work.
