This page is for Los Angeles homeowners whose Rheem system is misbehaving. Whether it’s a Classic 90 Plus in a 1950s Pasadena bungalow or a Prestige series condensing unit in a West Hills newer build, you’ll find the repair costs, the likely culprits, and what we do differently. The short version: we show up when we say, we diagnose honestly, and every repair is covered in writing for 365 days.

How Rheem Products Fail – and How We Fix Them

Rheem builds dependable equipment, but every brand has patterns. Here are the failure modes we see most often on Rheem furnaces across Los Angeles:

• Ignitor failure on Classic 90 Plus and Criterion II units. Rheem’s older silicon nitride ignitors are durable, but after 10 – 15 years they develop hairline cracks that prevent the gas from lighting. The furnace tries three times, then locks out. We confirm with an ohm reading, then install an OEM or equivalent nitride ignitor and verify the flame sensor signal before we leave. Most ignitor jobs run $150 – $280.
• Flame rollout trips on Prestige series condensing furnaces. Rheem’s high-efficiency heat exchangers run hot, and if the secondary heat exchanger gets restricted by dust or a failing inducer motor, the rollout switch trips. Some companies just reset the switch. We trace the actual cause. In a Prestige R96V, that’s usually a weak inducer or a blocked condensate trap, not the switch itself.
• Blower motor run capacitor degradation. This is the most common Rheem repair we see in Los Angeles because our winters are mild, so furnaces sit idle from March to November, and capacitors dry out in the heat. A weak capacitor means the blower hums but won’t spin, or it overheats and trips the limit. We test capacitance under load, not just visually. Replacement runs $175 – $325 parts and labor included.
• Gas valve pressure drift on R801T and R802T 80% models. The valve assembly on these mid-efficiency units can drift slightly out of spec over years of thermal cycling. The symptom is usually a lazy, orange flame or intermittent ignition failures. We verify inlet and manifold gas pressure with a manometer (a gauge that measures gas pressure), then adjust or replace the valve as needed. A new valve runs $275 – $525 installed.
• Limit switch fatigue on older 80% Rheem models from the 1990s and early 2000s. Los Angeles has a lot of these still running. The limit switch is a little heat-sensitive disc that shuts the burner off if the furnace overheats. After 20 years, the metal fatigues and the switch trips at lower temperatures or refuses to reset. We stock common limits for Rheem 80% units, so these are often a one-visit fix, typically $160 – $240.

Our Rheem Furnace Repair Process

Every Rheem repair at Cold Harbour Heating and Air Los Angeles follows the same sequence. Here’s what happens when you call:

1. 1
   You talk to a person, not a recording. A live dispatcher answers 24/7, takes the details, and gives you a firm arrival window. If your furnace is out, we move you into the emergency queue, no overtime surcharge.
2. 2
   Our technician arrives in the window we gave you. Uniformed, background-checked, and driving a marked vehicle. Victor Mancini grew up in Boyle Heights, and he’s seen every heating setup Los Angeles has to offer, so whatever you’ve got in the closet or attic, we’ve handled it before.
3. 3
   Diagnostics run before any tools touch the unit. We test the ignitor, flame sensor, gas pressure, blower motor, and control board, then tell you exactly what failed and why. You get a written price for the specific repair, no work starts until you approve it, and that price doesn’t change at the door.
4. 4
   We repair using OEM or equal-quality aftermarket parts. For Rheem furnaces, we’ll always give you the choice. On safety components like gas valves and flame rollout switches, we recommend OEM. On things like capacitors and ignitors, quality aftermarket often performs identically for less.
5. 5
   We test the full sequence of operation. The furnace fires, cycles through all safety checks, and delivers correct temperature rise. Then we walk you through what we found and what we did, in plain English, no jargon.
6. 6
   You get the 365-Day Done Right Promise in writing before we leave. If that repair fails within one year, we come back and make it right at no charge. We don’t just say it. We hand it to you on paper.
