If you're dealing with warm air blowing from the vents, ice forming on the copper line, or a condenser fan that's stopped spinning outside, you already know a system that's technically running but not actually cooling the house is one of the most misdiagnosed HVAC complaints there is.

Turned out to be a slow leak at the schrader valve — they found it with dye, fixed it, and recharged properly.
Outdoor unit had ice forming on the copper line which I'd never seen before.
They caught it before the compressor overheated and swapped the fan motor same visit.
Their tech knew it on sight and had a replacement part on the truck.

A full diagnostic checks all three before we touch the refrigerant charge.
Turn the system off, set the fan to run, and call — running a frozen coil makes the underlying problem worse.
Adding refrigerant without finding the leak just means another service call later.
