Goodman AC Not Cooling? Common Causes & How to Fix It

First, the fast checks

If your Goodman AC is running but not cooling, run through the five checks that resolve most no-cool calls:

1. Thermostat - set to COOL, target below room temp, fresh batteries.
2. Air filter - a clogged filter is the #1 sneaky cause; it chokes airflow and freezes the coil. Replace it if it's dirty (how to).
3. Breakers - reset the indoor and outdoor AC breakers once. Repeated trips = call a pro.
4. Outdoor unit - confirm the fan is spinning and the disconnect is in; clear debris around it.
5. Frozen coil - ice on the lines means shut the AC off (fan ON) to thaw, then run with a clean filter.

Still not cooling? Here's what's most likely on a Goodman.

The Goodman-specific causes we see most

• Failed run capacitor or contactor. By far the most common Goodman no-cool cause - and good news, it's a cheap, fast fix thanks to Goodman's inexpensive, widely stocked parts. If the outdoor fan hums but won't spin, this is usually it.
• Evaporator-coil refrigerant leak. The classic Goodman complaint, especially on older units (the R-22-era coils were leak-prone; modern units are much better). Low refrigerant shows up as ice on the lines and weak cooling.
• Condenser fan-motor failure - the outdoor fan won't run, the system overheats and shuts down on a hot day.
• Control-board faults.

See the full list on our Goodman repair page, and our general guide to why an AC stops cooling covers the rest.

When to call a pro

Call a licensed tech if the coil keeps freezing, the outdoor fan won't spin, you suspect a refrigerant leak, or the breaker trips repeatedly. The upside with Goodman: parts are cheap and everywhere, so these repairs are among the most affordable of any brand - see our Goodman brand review.
