How Rheem Products Fail – and How We Fix Them

Rheem builds solid equipment, but every brand has its weak spots. Here are the Rheem-specific failure patterns we see on AC installation jobs across Marietta neighborhoods, from East Cobb to Sandy Plains to the Whitlock Avenue corridor.

• Rheem Classic Series (RA14/RA16) – evaporator coil corrosion. The Classic Series is a workhorse, but in older Marietta homes with high attic humidity, we regularly find corroded evaporator coils that leak refrigerant slowly. The symptom is a system that cools fine in the morning and struggles by late afternoon. On an install, we always pressure-test the coil before reusing it with a new outdoor unit. If it’s marginal, we replace it.
• Rheem Prestige Series (RA17/RA20) – variable-speed fan motor failures. The Prestige line’s variable-speed blowers are great for humidity control, but Georgia summers run them hard. When the fan motor fails, the outdoor unit still runs, the house just never reaches temperature. We always check the blower module and ECM motor when we install a new system, because a failing motor can take down a brand-new condenser.
• Rheem water heater thermostat fail-safe mode. This one is not an AC issue, but we see it often enough on Rheem households getting a full HVAC install that it is worth a heads-up. Rheem water heaters can enter a fail-safe state that shuts down the heater after a power flicker. If your hot water goes cold after a Kennesaw-area storm, check the thermostat reset buttons before calling anyone.
• Rheem RA14 heat pump – defrost control board failures. On heat pump installs in west Cobb homes, the defrost board is a common failure point. When it goes, the outdoor unit freezes up in winter and the system switches to emergency heat, sending your power bill through the roof. We replace these boards with OEM or high-quality aftermarket parts, and we wire in a defrost sensor check on every new install.
• Rheem control board capacitor failures across most series. Rheem units use a dual-run capacitor that sees brutal heat on Marietta rooftops and side yards. A failing capacitor is the most common no-cool issue we see on Rheem systems in the middle of a Georgia summer. It’s a simple fix, but if you ignore it, it can take out the compressor. We test capacitor health on every visit and replace weak ones before they strand you in July.

Our Rheem AC Installation Process

Here is what a Rheem AC installation looks like when we handle it, from the first call to the final walkthrough. No mystery steps, no surprises.

1. 1
   You call, a live person picks up. No voicemail tree, no “press 2 for new installations.” We ask what the system is doing, what the house feels like, and when you need it done.
2. 2
   We come out and measure. Before we quote a dollar, we do a load calculation on the house. Square footage, window orientation, insulation, duct condition, the whole picture. A properly sized Rheem system is the difference between a comfortable Marietta summer and one where the AC never shuts off.
3. 3
   We hand you a written price. Not an estimate with a range that might change. A price. It covers equipment, labor, refrigerant, electrical, permits, and disposal. It does not change at the door.
4. 4
   We do the install. This is where we pull the old unit, inspect the lineset, test the ductwork, and set the new Rheem condenser and evaporator. We use nitrogen to check the line for leaks, pull a proper vacuum, and charge the system to the manufacturer’s spec, not a guess.
5. 5
   We test, then we test again. The system runs through a full cycle with temperature probes on the supply and return. We check the amp draw on the compressor, the capacitor, and the blower. You get a written report of what we found.
6. 6
   You get your 365-Day Done Right Promise in writing. If the installation fails within a year, we come back and correct the work at no charge. That is not a verbal promise. It is on paper before we leave.

What Rheem AC Installation Costs in Marietta

Most Rheem AC installations in Marietta run between $3,500 and $7,500, parts and labor included. Here is how that breaks down based on what you choose:

• 13 – 14 SEER Rheem Classic central AC: $3,500 – $4,800. This is the budget-friendly workhorse. Good efficiency, lower upfront cost, ideal for rentals or homes you may sell soon.
• 16 – 17 SEER Rheem Prestige central AC or heat pump: $5,000 – $6,500. The sweet spot for most Marietta homeowners. Better humidity control, quieter operation, lower summer power bills.
• 18 – 20 SEER Rheem Prestige variable-speed heat pump: $6,000 – $7,500. Top of the line for comfort and efficiency. Great for homes with older ductwork that needs a gentler airflow.

What moves the price? Ductwork, mostly. If your existing ducts are leaky or undersized, we may need to repair or replace them. Some older east Cobb homes have ducts that were designed for a furnace, not a heat pump, and that matters for efficiency. The thermostat is another variable: a communicating Rheem thermostat for variable-speed systems costs more than a basic digital model. We’ll show you the full picture before you sign anything.
