Rheem furnace repair in Marietta typically runs $150 – $700 depending on the part that failed, with most jobs diagnosed and fixed in a single visit. We are an independent Rheem service provider, not a factory-authorized shop, which means we give you a straight answer on parts and price rather than a corporate script. If your Rheem is blowing cold air, making noise, or refusing to start, call (762) 240-5599. This page is for Marietta Rheem owners who want to know what is actually wrong, what it costs, and whether it is worth fixing.
How Rheem Products Fail – and How We Fix Them
Rheem builds a solid furnace, but every brand has its patterns. After years of opening these cabinets in Marietta homes from East Cobb to Powder Springs, here is what we actually see:
- Classic 90 Plus pressure switch trips. Rheem’s 90 Plus line uses a pressure switch to confirm the inducer draft is pulling correctly before the burners light. In Georgia humidity, condensation lines inside the furnace trap water, the switch reads low draft, and the unit locks out. The fix is usually clearing the trap and verifying the inducer, not replacing the switch.
- Rheem gas valve solenoids sticking on older RGPS models. The RGPS series (installed in a lot of Marietta homes built in the late 1990s and early 2000s) uses internal solenoids that wear unevenly. The symptom is intermittent ignition: it lights some mornings and not others. We test the valve for resistance before condemning it. A quality aftermarket replacement often outlasts the OEM in this case.
- Spark ignitor buildup on R95T and R96V models. The direct-spark ignitor gathers oxidation over three or four heating seasons and stops throwing a strong enough arc. The classic Rheem tell is a clicking sound with no flame. A cleaning sometimes works; a failed ignitor is an honest $150 – $280 repair, parts and labor.
- Inducer motor bearing whine on Rheem Prestige series. Prestige units (the R97V mod range) run quiet when new, which makes a failing inducer bearing extremely obvious. That high-pitched whir that starts at call-for-heat and fades after the burners light is almost always the inducer wearing out, not the blower. We replace it before it locks up mid-winter.
- Heat exchanger rust at the primary cell welds on older drum-style Rheems. Any furnace that has seen 15-plus Georgia winters will show some rust, but Rheem’s older drum-style heat exchangers rust at the weld seams first. That shows up as a faint metallic smell at startup. We scope the cell. If it is cracked, we recommend replacement, not patchwork.
Styles & brands we work with







Our Rheem Furnace Repair Process
A Rheem job at Cold Harbour follows the same steps whether it is a $160 ignitor or a $700 gas valve. No shortcuts, and a written price before any work starts.
- 1
You call (762) 240-5599. A live person answers, day or night, and schedules a firm arrival window. No voicemail tree, no waiting until Monday morning.
- 2
We arrive, boot covers on, and listen. Victor Mancini trained the crew to ask the question he always asks: what is the system doing, and when does it do it? Half of Rheem diagnoses happen in that conversation.
- 3
We test, not guess. Manometer on the pressure switch, multimeter on the ignitor, visual scope on the heat exchanger. The multimeter does the talking.
- 4
We price the repair in writing. OEM Rheem part cost versus quality aftermarket, explained in plain English, with our recommendation. You see the number before a single tool comes out.
- 5
We fix it, test it, and document it. Three full cycle tests before we pack up. Photos of the old and new parts go in your job record.
- 6
You get the guarantee on paper. The 365-Day Done Right Promise: if that repair fails inside a year, we come back and correct it at no charge.

Why Marietta Homeowners Call Cold Harbour Heating and Air Marietta for Rheem Work
We are an independently operated part of the Kingswell network, founded in 2003. Being independent means no corporate overlord sets our parts markup and no regional manager pushes a sales quota on every truck. The Kingswell Way is five written promises: say the price before the work, show up in the window given, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. That last one has teeth. The 365-Day Done Right Promise is printed on your invoice, not just mentioned in passing. And if your Rheem is beyond saving and you want to compare brands before replacing, our crew works on Carrier, Trane, and Lennox systems too. We are not married to one manufacturer. We are married to the house staying warm.
One more thing. A cold harbour was a roadside shelter where travelers waited out the weather. Comfort in any season is the job. We take that literally.
FAQs
Most calls are scheduled within 24 hours, and because we keep Rheem-specific ignitors, flame sensors, pressure switches, and gas valves in our truck stock, many repairs finish on the first visit. If the system is down on a cold night, tell the live person on the phone; we prioritize no-heat calls. Call (762) 240-5599.
No. Under federal Magnuson-Moss law, a manufacturer cannot require factory-authorized service to keep the warranty valid. We perform warranty-safe repairs using OEM Rheem parts or quality aftermarket equivalents, and we document everything for your records.
The honest rule: if the repair costs more than half the value of a new furnace, replace the furnace. Rheem furnaces from the RGPS and early 90 Plus era are 20 to 25 years old now. A gas valve and inducer on the same unit often pushes past that line. We will tell you which side of it you are on. Call us for a free assessment.
Yes. Every Rheem repair we perform carries a written 365-day guarantee. If that repair fails within the year, we return and correct the work at no charge. It is printed on your paperwork before we leave. No fine print, no phone argument.
In East Cobb and around Kennesaw Mountain, we see a lot of Rheem 90 Plus, RGPS, and R95T furnaces from the mid-1990s through late 2000s. In newer construction, the R96V two-stage and R97V Prestige mod units are common. Each line has its own failure patterns, and we diagnose them accordingly.
We would rather you did not open a gas appliance on your own. A furnace gas line, burner assembly, and flue are not a hobby job. Leave the cabinet closed and call us: (762) 240-5599. The diagnostic tells us whether it is even the ignitor, and the repair carries a guarantee that a DIY fix never will.
