On arrival system running and cooling as intended. Indoor unit passed all electrical testing. Scoped supply plenums and heat strips to try to identify the cause of the breaker tripping at the panel in heating but found no issues and had no issues in heat mode. Outdoor unit passed all electrical testing but the compressor overamped on start up. Recommended a compressor saver kit to reduce wear and tear and increase life of compressor. Customer would like an electrical and plumbing visit scheduled.
