Found unit with the compressor locked up, freed up compressor, unit sounds rough so ordering a compressor to be installed, removed and replaced with a new compressor, vacuum system down, charged with 3.5 pounds of R410A, cycled all equipment, all operations ok at this time. Unit does need condenser coil cleaned also but will have to be approved since no water is onsite we have to bring a tank and pump to clean it like we have done at other sites.
