Manifold gauges are attached to the high and low side service ports, the system is run for a few minutes, then readings are taken of the gauges. IF the system were blocked, and that is likely, the gauges would tell us by the readings. Temp in the mid 70's, the compressor SHOULD be cycling on and off every 90 seconds or so. If not cycling, something is wrong.
