How Goodman Products Fail – and How We Fix Them

Goodman builds honest equipment at a fair price. That’s why so many Alpharetta homes have them. But after years in the field, we see the same failure patterns repeat. Here’s what actually happens, model line by model line.

• GSZ/GSH split heat pumps: leaking evaporator coils at the 7 – 10 year mark. The coil’s copper tubing and aluminum fins expand and contract through Georgia’s hot-wet summers and cold snaps. That thermal cycling eventually creates pinhole leaks at the brazed joints. We find the leak with nitrogen pressure and electronic leak detection before we quote anything, because a guessed repair on a coil is a wasted repair.
• Goodman AVPTC air handlers: failed ECM blower motors. The variable-speed blower motor in the AVPTC runs nearly constantly in Alpharetta humidity. When the motor module fails, the unit still hums but the airflow collapses. We stock OEM and quality aftermarket blower modules specific to this air handler, so you’re not waiting three days on a supplier who doesn’t answer.
• Defrost control board failures on older GSZ14 units. When the defrost board quits, the outdoor coil ices up in winter and the unit starts sending cold air into the house. The board is a known weak point on early GSZ14 production. We replace it with the updated OEM board, set the defrost interval correctly, and verify the suction-line thermistor is reading true.
• Reversing valve sticking on units that sat idle all summer. In Alpharetta, heat pumps run cooling mode from April through October. The reversing valve, the part that flips the refrigerant flow between heating and cooling, rarely cycles. When it’s finally asked to move on the first cold night in November, it sticks. A stuck valve means the unit won’t heat. We test it before condemning it, because a low refrigerant charge can mimic the same symptom.
• Incorrect charge from the previous install. This isn’t a Goodman defect. It’s an installation defect. Heat pumps need the refrigerant charge set by subcooling or superheat, not by sight glass or guesswork. We recover the charge, pull a proper vacuum, and weigh in refrigerant per the data plate. On a Goodman, proper charge is the difference between a 12 SEER unit that cools fine and one that costs you $80 extra a month in August.

Our Goodman Heat Pump Installation Process

Here’s how a Goodman heat pump installation goes at Dalton Heating & Air Alpharetta, from the first call to the final walkthrough.

1. 1
   You call, we answer. A live person picks up at (229) 537-2086. We schedule a time and give you a real arrival window. Then our tech shows up inside that window, background-checked and in uniform.
2. 2
   Load calculation and assessment. We measure the house, check the ductwork, and run a Manual J load calculation. Square footage alone doesn’t cut it. East-facing windows, vaulted ceilings, and that uninsulated garage wall all move the number. We size the Goodman unit to the house, not to what’s on the slab today.
3. 3
   Written price before anything happens. We hand you a written quote that covers equipment, line-set, pad, electrical, thermostat, and any duct transitions. That number doesn’t change. No add-ons at the door, no “while we’re here” pricing.
4. 4
   Install day. We remove the old equipment, set the new Goodman outdoor unit on a level pad, replace the line-set, braze with nitrogen flowing to prevent oxidation inside the copper, pull a deep vacuum, and weigh in the refrigerant to manufacturer spec. The air handler gets inspected, the filter gets replaced, and the condensate drain gets cleared.
5. 5
   Startup and test. We fire the system, check temperature split, verify the reversing valve switches over, and calculate subcooling and superheat. The unit runs through a full heating and cooling cycle before we leave.
6. 6
   Written guarantee and cleanup. Every installation carries a written, signed guarantee. We walk the job site with you, show you the thermostat, and leave the area cleaner than we found it. That’s The Garrison Code. We have operated under it since 2003.

What Goodman Heat Pump Installation Costs in Alpharetta

Straight numbers, because you asked. A 14 – 16 SEER single-stage Goodman heat pump replacement with a matching air handler in Alpharetta typically runs $3,500 – $5,500. A 16 – 18 SEER two-stage system runs $5,500 – $7,500. That includes the outdoor unit, air handler, new line-set, electrical disconnect, pad, thermostat, and labor.

What moves the price: duct modifications, crane work if your unit sits on a steep lot, electric panel upgrades if your existing breaker isn’t sized for the new heat strip, and line-set length beyond the standard 15-foot run. Older Alpharetta homes, especially those built before 1990 around the Windward area, often need a minor duct transition because the existing plenum doesn’t line up with the new air handler. We tell you about that in the written quote, not after the old unit is in the truck. Call (229) 537-2086, and we’ll give you a free, in-writing estimate for your specific house.
