Over-charge → compressor overheats and capacity drops.
Cure: leak-test, repair, then weigh in factory charge. -

Set-point too high in summer or too low in winter, or sensor is in a draft / sun patch.
Cure: check set-point, calibrate or relocate sensor. -
Blocked or leaky ductwork
Closed dampers, crushed flex, torn insulation, or open crawl-space return steal capacity.
Cure: inspect ducts, seal leaks with mastic, balance dampers.
