Rheem AC repair in Marietta typically runs $150 – $650 depending on what’s failed, and most jobs are completed the same day we diagnose them. We’re an independent Rheem service provider, which means we work on your system the way a factory-trained technician would, without being tied to Rheem’s corporate service schedule. If you’re a Rheem owner in Marietta whose AC is blowing warm, short cycling, or dead altogether, this page covers what’s actually going wrong, what it costs to fix, and when it makes sense to repair versus replace. Call (762) 240-5599 and a live person answers, any hour.
Key Takeaways
- Most Rheem repairs in Marietta fall between $150 and $650, parts and labor included.
- Rheem systems have specific weak points: capacitors on RA14/RA16 condensers, ECM motor modules on RA17/RA20 units, and control board corrosion on older RAKA packages.
- We write the price down before any work starts and we honor that price at the door.
- Every repair carries our 365-Day Done Right Promise in writing. If the fix fails within a year, we come back free.

How Rheem Products Fail – and How We Fix Them
Rheem builds solid equipment, but every brand has its patterns. After years of working on Rheem condensers across Marietta, East Cobb, and the neighborhoods near Kennesaw Mountain, these are the failures we see most:
- Dual run capacitors on RA14 and RA16 condensers. This is the single most common Rheem failure in Georgia heat. A capacitor gives the compressor and fan motor the jolt they need to start. When it weakens, your outdoor unit hums but won’t kick on, or the fan spins slowly. The fix is usually a $150 – $300 replacement with an American-made capacitor that matches Rheem’s microfarad rating exactly. Swapping in a “close enough” capacitor is how you get a compressor that dies two summers later, and we won’t do that.
- ECM blower motor modules on RA17 and RA20 variable-speed air handlers. Rheem’s high-efficiency lines use ECM motors, which are great until the module the drives them fails. Symptom: the indoor fan runs at full blast constantly, or barely moves air at all. The motor itself may be fine. We test the module separately before quoting a full motor replacement, which saves you $400 – $600 over what a parts-swapper would charge.
- Refrigerant leaks at the evaporator coil on aging RAKA and RANL package units. Older Rheem package units, the kind that sit on the ground or a rooftop in a Marietta ranch home, are prone to formicary corrosion on the indoor coil. That’s a fancy way of saying the copper gets microscopic pinholes from years of Georgia humidity and household chemical exposure. A leak search and repair runs $250 – $700 depending on access, and we will tell you plainly if a coil replacement makes more sense than patching a 15-year-old evaporator.
- Condensate drain clogs and float switch trips on Rheem air handlers in humid crawlspaces. Marietta’s summer humidity means AC systems dump gallons of water. Rheem’s horizontal air handlers in crawlspaces clog at the drain pan if the trap wasn’t cleaned. Your unit shuts off and the thermostat goes dark. Simple fix: clear the line, clean the trap, test the float switch. Runs $150 – $200. Skipping this service turns into a ruined blower motor or a collapsed ceiling, and we’d rather prevent that.
- Contactor failures on Rheem Prestige and Classic series condensers. The contactor is the electrical relay that tells the compressor and fan to start when your thermostat calls for cooling. Ants love to crawl into contactors and fry them. Happens constantly in Marietta’s older tree-lined neighborhoods. A new contactor is usually under $200 installed. If we see ant activity, we’ll tell you so you can have pest control treat the area before the next one fails.
Our Rheem AC Repair Process
Victor Mancini has a rule on Rheem jobs, and it’s the same one his crew follows: “Tell me what the system is doing, and I will tell you exactly what it needs – no guesswork, no runaround.” Here’s how a typical Rheem repair goes at Cold Harbour:
- 1
You call (762) 240-5599. A live person answers. You describe the symptom: not cooling, blowing warm, loud noise, frozen coil. We schedule a firm arrival window that same day or next morning.
- 2
The technician arrives and does a full diagnostic. We check refrigerant pressures, capacitor readings, contactor condition, amp draw, and airflow. We don’t guess at the problem because guessing at Rheem parts costs you money.
- 3
You get a written price before any tool touches the unit. We hand you the number. It does not change at the door. If the repair is bigger than expected, we stop and explain the options in plain English: OEM Rheem part, quality aftermarket equivalent, or replace.
- 4
We repair with the right part. For warranty-covered Rheem systems, we use OEM parts so your manufacturer warranty stays intact. For out-of-warranty systems, we use OEM when it matters and quality aftermarket when it saves you real money without cutting corners.
- 5
We test the system, not just the part. After the fix, we run the unit through a full cooling cycle, check the temperature split at the supply and return, and verify the refrigerant charge. The job isn’t done because the part went in. It’s done because the air is cold.
- 6
You get a written 365-Day Done Right Promise before we leave. If a repair fails within a year, we return and fix it at no charge. No phone tag, no arguing, no fine print.

Why Marietta Homeowners Call Cold Harbour Heating and Air Marietta for Rheem Work
Most of our Rheem repair calls in Marietta come from neighbors referring neighbors. That’s not a brag; it’s just how we’ve worked since 2003. Here’s what keeps people calling:
- The 365-Day Done Right Promise, in writing. Every Rheem repair gets a written guarantee valid for a full year. If the same repair fails in that window, we come back and fix it at no charge. Not a pro-rated refund, not a credit toward a future job. A free second visit, stated on paper before we leave.
- A price before the work starts. You know the number before a single tool comes out. That’s how The Kingswell Way operates: 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.
- Techs who know Rheem, and eight other brands too. Our technicians are trained on Rheem, Carrier, Trane, Lennox, Goodman, York, Daikin, Bryant, and American Standard. If your Rheem is paired with a different-brand coil or thermostat, we handle it without blinking.

FAQs
No, using an independent Rheem service provider like Cold Harbour Heating and Air Marietta will not void your Rheem manufacturer warranty, as long as the repair is done properly and documented. We use OEM Rheem parts on warranty-covered systems specifically to protect your coverage, and we keep detailed service records so your warranty claim stays clean.
In most cases, yes. Common Rheem failures like capacitors, contactors, and drain clogs are fixed the same day because we carry those parts on our trucks. Bigger jobs like an ECM motor replacement may need a day for parts. Call (762) 240-5599 and we’ll tell you straight what to expect.
If your Rheem is under 10 years old and the repair is under $1,000, repairing is usually the smart call. If the system is over 15 years old and the compressor has failed, or the coil is corroding and leaking, replacement starts making more financial sense. We’ll give you the numbers for both options and recommend the cheaper long-term path, not the one that pads our invoice. A new Rheem system in Marietta typically runs $3,500 – $7,500 installed.
Yes. If your Rheem compressor or coil is still covered under the manufacturer’s parts warranty, we handle the warranty paperwork and only charge for labor. You’ll see exactly what your warranty covers and what your out-of-pocket labor cost is before we start the repairs.
A frozen Rheem coil in summer almost always means low refrigerant from a slow leak or restricted airflow from a clogged filter or dirty evaporator. Turn the system off, set the fan to “on” to thaw the coil, and call us. Running it frozen can destroy the compressor, and that’s a $2,500+ lesson no Marietta homeowner wants. Call (762) 240-5599 and we’ll diagnose it before the damage spreads.
If your Rheem AC is struggling through another Georgia summer, don’t wait until it quits entirely. Call (762) 240-5599 for a free repair estimate. We’ll give you an honest diagnosis, a written price, and a guarantee we’re proud to put on paper. Same-day service for most repairs, and a live person on the phone whenever you call.
