A fan that sounds healthy while the room never cools is usually electrical rather than mechanical. A tired run capacitor stops the compressor turning while the rest of the system carries on as though nothing is wrong.
We measure amp draw against the data plate, check the contactor faces, test the capacitor under load rather than at rest, and confirm the winding resistances before condemning anything expensive.
Where a compressor genuinely has failed we say so plainly, show you the numbers behind that verdict, and price the repair against a replacement so the decision is yours to make.
