This page is written for Houston homeowners who own a Rheem furnace and want straight answers about what’s failing, what it should cost, and whether the repair makes sense versus replacement. We’ll walk through the specific ways Rheem furnaces fail in Houston’s climate, which models we see most often, and exactly how we diagnose and fix them. No brand fluff, no vague estimates.

How Rheem Products Fail – and How We Fix Them

• Classic 90 Plus and Classic 95 pressure switch lockouts. These mid-efficiency Rheem lines use a pressure switch that confirms the inducer fan is pulling combustion gases correctly. In Houston’s humidity, the rubber tubing to the switch collects condensation and clogs with dust. The furnace throws a pressure switch fault and won’t fire. We clean or replace the tubing, verify the switch’s threshold with a manometer, and clear the code. It’s a 40-minute job, not a new control board.
• Rheem Prestige and R95T/R96T ignitor failures. Rheem’s newer high-efficiency lines use a silicon nitride ignitor. It’s durable, but voltage spikes from Houston’s storm season or a weak ground at the power source can crack it. Symptom on the thermostat: the furnace attempts ignition, you hear the gas valve click, but no flame. We test ignitor resistance before replacing it, and we check the incoming voltage to make sure the next ignitor doesn’t die in six months.
• Rheem Classic 80 and older standing-pilot units at the gas valve. Homes in older Houston neighborhoods like Timbergrove or Meyerland still run these. The gas valve solenoid burns out or the valve seat gets gummy from years of humid air infiltration. We test gas pressure at the manifold and verify the valve’s output with a digital manometer. If the valve is bad, we replace it with an OEM Rheem valve – this is not the part to save thirty dollars on aftermarket.
• Heat exchanger cracking on Rheem furnaces 12 to 15 years old. We see this on Rheem 90s and early R92T units that ran hard through hot Houston summers with dirty filters, forcing the exchanger to overheat repeatedly. The symptom is a faint metallic smell in the first few minutes of a cycle, or a flame that rolls back when the blower kicks on. We inspect with a borescope and combustion analysis. If the exchanger is cracked, the repair rarely makes sense – we’ll tell you straight and give you replacement numbers.
• Blower motor capacitor failures on Rheem R96 and R97 mods. These modulating furnaces use ECM blower motors that ramp gradually. When the capacitor that smooths the motor’s power supply degrades, the blower stutters or runs at full speed constantly, and your utility bill in Houston shows it. We replace the capacitor and test the motor’s amp draw to confirm the motor itself is still healthy before calling the repair done.

Our Rheem Furnace Repair Process

1. 1
   You call (903) 494-7686. A person picks up, not a queue. You tell us what the furnace is doing or not doing. We schedule a window and we arrive inside it.
2. 2
   We listen and look. Before opening the cabinet, we ask when the problem started and what the thermostat was doing. Marco’s rule: “Tell me what the system is doing, and I’ll tell you what it needs – not what sells.”
3. 3
   We test, not guess. We run the furnace through a full cycle. Gas pressure, inducer pull, ignitor resistance, flame sensor microamps, blower amp draw, temperature rise across the exchanger. We show you the readings if you want to see them.
4. 4
   You get a written price. The cost, the specific part, OEM or aftermarket, and the labor are on paper before any work starts. No verbal estimate, no add-on surprises.
5. 5
   We fix it and prove it. We install the part, run multiple cycles, and verify the furnace fires reliably and within spec. We clean the work area and take the old part unless you want to see it.
6. 6
   You get the 365-Day Done Right Promise in writing. If the repair fails within a full year, we return at no charge, no questions. That’s the Garrison Standard. It’s been that way since 2003, and it applies to every Rheem job we do in Houston.

What Rheem Furnace Repair Costs in Houston

Most Rheem furnace repairs in Houston fall between $150 and $450, with the full range running $150 to $700 depending on the part. Here’s the breakdown we use when we quote:

• Flame sensor cleaning or replacement: $150 – $250
• Ignitor replacement: $225 – $400
• Pressure switch or tubing repair: $180 – $320
• Gas valve replacement: $350 – $600
• Blower motor or capacitor: $200 – $500
• Control board replacement: $300 – $700
• Heat exchanger inspection (with borescope and combustion test): $150 – $250, waived if you proceed with the repair

What moves the price: the part itself, whether we use OEM Rheem or a quality aftermarket equivalent, and how long diagnostics take on a furnace that’s been intermittently failing. We give you a written price before any work begins, so the number we quote is the number you pay. For a free estimate on your Rheem furnace, call (903) 494-7686.
