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.
