Rheem furnace repair in Alpharetta typically runs between $150 and $700 depending on the part that failed, and most jobs are done in a single visit. We’re an independent Rheem service provider, not a Rheem-authorized dealer, which means we answer to you, not a manufacturer quota. If your Rheem furnace is down, call (229) 537-2086 and a live person picks up, day or night.
This page is for Alpharetta homeowners who own a Rheem furnace and want straight answers before a tech ever pulls into the driveway. Marco Benitez and our crew work on Rheem equipment every week across Alpharetta, including the neighborhoods off Windward Parkway and along Kimball Bridge Road. You’ll get a written price before any work starts. No exceptions.
How Rheem Products Fail – and How We Fix Them
- Classic 90 Plus inducer motor failure. This is the single most common Rheem repair we see in Alpharetta. The inducer motor pulls combustion gases through the heat exchanger and vents them outside. On Rheem’s 90 Plus line, the bearing wears out over time and you’ll hear a grinding or whining sound from the upper cabinet before the furnace refuses to fire. We replace the inducer assembly, usually same day, and the fix typically lands in the $300 – $550 range.
- Criterion II hot surface ignitor cracking. Rheem’s Criterion II furnaces from the early 2000s use a silicone nitride ignitor that gets brittle after years of heating cycles. When it cracks, the gas valve opens but nothing lights. The symptom is a furnace that runs the blower but never produces heat. This is a straightforward repair: new ignitor, and the furnace fires again. You’re usually looking at $180 – $300.
- Prestige series flame sensor fouling. The Rheem Prestige line has a flame sensor that confirms the burners actually lit. In Alpharetta, our humid summers and dusty springs coat that sensor with residue faster than in drier climates. The furnace lights, runs for a few seconds, then shuts off and tries again. Cleaning the sensor fixes most cases for under $150. If the sensor is cracked or the ceramic is damaged, we replace it.
- Classic Plus gas valve intermittent failure. On Rheem’s Classic Plus series, we occasionally see a gas valve that opens inconsistently. The furnace might fire fine for a week, then refuse to light on a cold morning. That’s a safety-critical part, not a DIY repair. The valve replacement usually runs $250 – $500, and we test every connection before we leave.
- Heat exchanger corrosion on older Rheem units. Any furnace over 15 years old, including earlier Rheem 80% efficiency models, can develop hairline cracks in the heat exchanger. These cracks let combustion gases leak into the airstream. This is a serious safety issue. If your furnace is older and you’re noticing a metallic smell when it runs or the burner flame flickers yellow when the blower kicks on, call us. We’ll camera-inspect the exchanger and give you an honest repair-or-replace recommendation. If it’s cracked, we’ll recommend replacement, not a patch job.
Styles & brands we work with







Our Rheem Furnace Repair Process
- 1
You call, a person answers. No voicemail queue. We schedule a window and we hit it, per The Garrison Code.
- 2
Diagnostics first. The tech checks the thermostat signal, the ignitor or pilot, the gas valve, the flame sensor, and the inducer. We show you what failed and explain it in plain English before quoting anything.
- 3
Written price before work begins. The price you see is the price you pay. Parts and labor, line by line, on paper. No surprises at the door.
- 4
Parts decision, made with you. We use OEM Rheem parts when it matters for warranty or fit, and quality aftermarket parts when they’re equivalent and save you real money. You’ll know which is which and why.
- 5
The repair and the test. We make the fix, then cycle the furnace at least three times to confirm it lights, heats, and shuts off correctly. We check for CO at the vents.
- 6
Cleanup and the written guarantee. We leave the work area cleaner than we found it, and you get a full-year written guarantee on the repair. If it fails within 365 days, we return at no charge.

AfterWhat Rheem Furnace Repair Costs in Alpharetta
Most Rheem furnace repairs in Alpharetta land between $150 and $700. The parts price drives most of the cost. Here’s what we typically see:
- Flame sensor cleaning or replacement: $120 – $180
- Hot surface ignitor replacement: $180 – $300
- Inducer motor replacement: $300 – $550
- Gas valve replacement: $250 – $500
- Blower motor replacement: $350 – $700
- Heat exchanger inspection: $90 – $150 (credited toward repair if you proceed)
What moves the price is age of the unit and parts availability. Older Rheem models sometimes need a part ordered, which adds a day but not much cost. Every quote is in writing before we start. Call (229) 537-2086 for an exact number on your Rheem furnace, free of charge.

FAQs
Yes, in most cases. We stock common Rheem parts like ignitors, flame sensors, and pressure switches on our trucks. For less common parts on older Rheem models, we may need to order overnight. When you call (229) 537-2086, tell us your furnace’s symptoms and model number if you have it. That speeds things up. We’ll give you a realistic arrival window, not a vague “sometime today.”
Yes. As an independent Rheem service provider, we follow Rheem’s documented repair procedures and use OEM parts when the job calls for it. Your registered manufacturer warranty stays intact. We don’t cut corners that would void coverage, and we’ll tell you flat-out if a repair is worth doing under warranty versus paying out of pocket.
If your furnace is under 12 years old and the repair is under $700, repair almost always makes sense. If it’s over 15 years old, has a cracked heat exchanger, or needs a repair north of $700, we’ll walk you through the replacement math: efficiency gains, rebates, and what a new properly sized unit costs in Alpharetta. We’ll show you the numbers and let you decide. No pressure either way. Call (229) 537-2086 and ask Marco to come take a look.
Our phones are answered by a live person 24/7. In a no-heat situation during Alpharetta’s cold snaps, we prioritize emergency calls and often have a tech out the same day. The dispatcher will give you a straight answer on timing when you call, not a callback window. (229) 537-2086.
That’s almost always a failed ignitor or a gas valve that isn’t opening. On Rheem Criterion II and Classic models, the ignitor is the usual suspect. On the Prestige line, we see more pressure switch issues. Tell us what it’s doing, and we’ll tell you what it needs – no guesswork, no markup on confusion. Call for a diagnostic, and you’ll get a written price before any repair begins.
