Rheem furnace repair in Jacksonville typically runs $150 – $700 depending on the part that failed, and most jobs are completed the same day we diagnose them. We’re an independent Rheem service provider, which means we work on every Rheem line that’s common in Jacksonville homes and we give you a written price before any work starts. If you own a Rheem and your heat is out, call (904) 456-0205 and a live person answers, any hour, any day.
How Rheem Products Fail – and How We Fix Them
- Ignitor failure on Rheem Classic 90 and 95 series. Rheem’s hot-surface ignitors aren’t more fragile than other brands, but they’re exposed to Jacksonville’s damp air most of the winter. Humidity settles on the ignitor during the off-season, and first start of the season cracks it. We replace these with either OEM Rheem nitrile ignitors or a quality aftermarket direct-fit, and the part plus install usually runs $150 – $300.
- Flame sensor carbon buildup across Rheem Criterion II furnaces. Older Criterion II units have a flat-shaped flame sensor that loves to collect residue. The furnace lights, runs about five seconds, then shuts off. A homeowner sees a furnace that “keeps turning off.” Nine out of ten Criterion II no-heat calls near Riverside and Avondale come down to a dirty flame sensor. We clean it first and confirm a stable microamp reading, rather than replacing a sensor that still has life.
- Pressure switch faults on Rheem 80% AFUE models with longer vent runs. Jacksonville homes frequently have furnaces in closets or utility rooms, and the venting gets creative: tight elbows, long horizontal runs, dips that collect moisture. Rheem’s pressure switches read the vent vacuum, and a sagging vent pipe makes the switch trip. Before we sell a new pressure switch, we inspect the full vent run because we’d rather fix a sagging pipe for a fraction of the cost.
- Draft inducer motor noise on Rheem Classic Plus and Prestige lines. A rattle or whine from the inducer area usually means bearing wear or a cracked fan wheel. On a Rheem, the inducer assembly is a common 10-to-15-year wear item whether you live in Arlington or Mandarin. We replace the entire assembly rather than just the motor, because a new motor on a brittle fan wheel means you’ll see us again sooner than you should.
- Gas valve intermittent failure on Rheem Criterion and older RGP models. Rheem gas valves from the late 90s and early 2000s develop a known issue where the valve clicks but doesn’t open consistently. The furnace works fine for a week, then won’t fire on a cold morning. We test valve inlet and outlet pressure, verify electrical load, and replace with a correct Rheem-spec valve so the manifold pressure stays correct for Jacksonville’s gas supply.

Our Rheem Furnace Repair Process
Here’s how a Rheem repair goes when you call us, from first ring to final walkthrough:
- 1
You call (904) 456-0205. A live person answers. No menu, no hold queue, no voicemail that hope-you-get-a-callback. You tell us what the furnace is doing, we book a window that works.
- 2
You get the tech’s name and photo before arrival. That’s the Threshold Verified standard. The person at your door matches the photo we sent. They show you a photo ID badge before they step inside.
- 3
Diagnosis happens before any work is approved. We test the sequence of operation, isolate the failed component, and tell you the real problem in plain words. No repairing guesses.
- 4
You get a written price first. Before we turn a wrench, you see the cost on paper. If we’re deciding between an OEM Rheem part and a quality aftermarket part, we’ll tell you the difference and the price difference.
- 5
The repair gets done, then tested. We don’t just fire the furnace and leave. We cycle the heat multiple times, check temperature rise, verify flame signal, and confirm safety limits.
- 6
You get a written guarantee. Every repair includes a 365-day written guarantee. If the same repair fails inside that year, we return at no charge and fix it again. That’s the Done Right Promise.

AfterWhat Rheem Furnace Repair Costs in Jacksonville
Most Rheem furnace repairs in Jacksonville fall between $150 and $700, parts and labor included, with the written price confirmed before we start. Ignitor replacement on a Rheem Classic 90 runs about $150 – $300. A flame sensor cleaning or replacement lands around $120 – $250. A draft inducer assembly on a Rheem Classic Plus or Prestige typically costs $350 – $650. Gas valve replacement runs $300 – $600 depending on the model. Heat exchanger work, when a Rheem furnace is still under the 20-year heat exchanger warranty, often costs labor only, which can range $400 – $700 for the labor involved. The thing that moves a price is the part itself. We’ll tell you the exact cost before we order anything. Call (904) 456-0205 for a free estimate on your Rheem.
Why Jacksonville Homeowners Call Brandt HVAC Co Jacksonville for Rheem Work
Devin Marlowe and our crew have turned wrenches on Rheem furnaces across Jacksonville for years. We know which Rheem series fail in which ways, and we won’t make you stand there wondering if the fix is right. Every job carries the 365-Day Done Right Promise: if a repair fails within a year, we come back and do it again without charge. Our technicians are background-checked, uniformed, and introduced to you by name and photo before arrival, backed by the Threshold Verified standard. And if you ever need service on a different brand – Carrier, Trane, or Lennox included – we handle those too. The name Brandt comes from an old word for firebrand, and keeping Jacksonville homes warm is exactly what that spelling was made for.
FAQs
Most Rheem furnaces carry a 10-year parts warranty if registered, and heat exchangers are often covered for 20 years. You’ll need the model and serial number from the inside of the furnace cabinet, and we can check those numbers for you during the visit before any paid repair is approved.
We use genuine Rheem OEM parts by default, and we’ll tell you when a quality aftermarket direct-fit part makes more sense. On anything inside the furnace cabinet that affects safe combustion, OEM Rheem is what we recommend and quote first. The choice is always yours, and the price difference is on paper before the work starts.
Most Rheem ignitor, flame sensor, and pressure switch issues are same-day repairs for Jacksonville homeowners. If a specialty part has to be ordered – an uncommon inducer assembly on a Prestige line, for example – we’ll tell you honestly up front and set a return appointment. Call (904) 456-0205 and we’ll tell you whether the part you need is on a local shelf or has to come from the warehouse.
If the repair is under $700 and the furnace is less than 12 years old, repair is usually the right call. If the heat exchanger has failed and the unit is an older Rheem Criterion, replacement starts to make more sense – and on most Rheem models, we’ll put that comparison in writing so you can decide with real numbers, not a sales pitch.
Every repair includes a written 365-day guarantee. If the same part or repair fails within that year, we return at no charge and make it right. That guarantee is in writing before we leave the driveway. Know what it is, know what it costs, know it’s covered – that’s the whole deal.
