That usually gives it away if charge is actually off.

In reply to - Edward posted an update in the group HVAC Installation Best Practices Suction 60 psi, superheat 20+, looked like low charge turned out to be airflow. Static was through the roof.

Motor can be spinning and pulling normal amps but still be running slow if the capacitor is weak. Slow fan on a 74°F day is enough to push head pressure higher than it should be.

When there’s no single failed component, you’re basically untangling years of small decisions that stacked up. Wiring gets added, rerouted, repurposed, and eventually the system still runs but not correctly. Those are always slow burns.
