Call (478) 662-5175

If you own a Goodman and you live in Marietta, you already know the drill: our summers don’t mess around. June through September, your condenser is out there working in 90-plus degree heat, often sitting in full sun on the west side of the house. That’s the reality of this market, and it’s why we treat Goodman maintenance as preventive work, not a formality. Call (478) 662-5175 and we’ll send a technician by name and photo before they arrive.

How Goodman Products Fail – and How We Fix Them

Goodman builds a solid, affordable unit, and we’ve worked on hundreds across Cobb County. But every manufacturer has its patterns. Here’s what we see repeatedly on Goodman systems in Marietta, and what we do about it:

• Capacitor fatigue on the GSX and GSZ lines. The GSX13, GSX14, and GSZ14 series are everywhere in Marietta. Their capacitors run hot in our climate, and when one fails, the compressor tries to start, hums, and trips. We check capacitor microfarad readings on every maintenance call, not just the ones where the unit won’t start. We replace failing capacitors before they strand you in July.
• Condensate drain clogs on horizontal units in attics and crawlspaces. Many Marietta homes, especially the older ones near Marietta Square and the Kennesaw Avenue corridor, have horizontal Goodman air handlers installed in tight attic spaces. Algae and dust build up in the drain pan and line faster than in vertical installs. We flush the line, treat the pan, and check the float switch every time. A ten-minute drain cleaning prevents a water stain on your ceiling.
• Contactor wear on 10-plus-year-old systems. The contactor is the electrical switch that tells your compressor to run. On older Goodman units, pitted or burned contacts cause intermittent cooling or a unit that won’t shut off. This is not a part Goodman’s own documentation tells you to watch closely, but it’s on our maintenance checklist. We test it under load and replace it with a sealed contactor when needed, usually under $100.
• Thermostatic expansion valve (TXV) sticking on higher-end comfort series. The Goodman ComfortNet and DSXC lines use more sophisticated refrigerant controls, and a sticking TXV causes uneven cooling and low refrigerant readings that look like a leak at first. We diagnose the difference before quoting a recharge, because misdiagnosing this costs you money and doesn’t fix the problem.
• Filter neglect damaging blower motors across every line. This is the one that costs Marietta homeowners real money regardless of model. A clogged filter starves the blower, overheats the motor, and shortens its life. When we replace a blower motor on a Goodman, the cost is typically several hundred dollars more than the filter changes that would have prevented it. We’ll tell you exactly which filter your unit needs and when to change it based on your house, pets, and return-air setup.

Our Goodman AC Maintenance Process

1. 1
   Call and scheduling. A live person answers at (478) 662-5175, 24/7. We confirm the call is for a Goodman, get the model number if you can read it, and schedule a window that works for you. Before the technician arrives, you get their name and photo by text.
2. 2
   Arrival and verification. The technician shows a photo ID badge at the door. You already know who to expect. No badge, no entry, and you should call us immediately if anyone else shows up claiming to be us.
3. 3
   Full system inspection. The technician checks the condenser outside, the air handler or furnace cabinet inside, refrigerant pressures and temperatures, electrical connections, the capacitor, the contactor, the drain system, and air temperature drop across the coil.
4. 4
   Written findings and price. If anything needs attention, you get the exact price in writing before any work begins. If the unit is healthy, we tell you that plainly and hand you the test results. Devin built this company around one habit: tell people the truth and charge a fair number.
5. 5
   Maintenance work, when approved. We use OEM Goodman parts when warranty or age demands it, and quality aftermarket parts when they’re the better value. We explain the difference and let you decide.
6. 6
   Cleanup and the guarantee. We leave your equipment and property cleaner than we found it. Every repair is covered by our 365-Day Done Right Promise: if it fails within a year, we come back at no charge. Period.

What Goodman AC Maintenance Costs in Marietta

A standard Goodman tune-up in Marietta runs $80 – $200, depending on system type and condition. That includes the inspection, coil cleaning, drain flush, capacitor test, and refrigerant check. If we find a real problem, repairs on Goodman units typically fall between $150 and $650, with the most common items being capacitors, contactors, and drain repairs.

What moves the price: accessibility of the air handler, age of the system, whether it uses R-22 or R-410A refrigerant, and whether the failure happened during a heat wave when we’re running calls back-to-back (our pricing doesn’t change with the temperature, but the diagnosed repair scope does). Every quote is written, fixed, and agreed to before work starts. Call (478) 662-5175 for a free estimate on Goodman maintenance or repair.
