Arrived to inspect and repair a 3 indoor headed minisplit. Unit is low on refrigerant, has a standing pressure of 132 / 46*, should be 170 / 60* based on indoor and outdoor ambient. Searched all 3 indoor coil and flare fittings as well as outdoor coils and flare fittings. Identified 2 leaks at outdoor flare reducers. During initial installation some type of putty was used on fittings and has now dried and is leaking. Photos attached Need to return to fix leaks and clean indoor blower wheels. Leaks are at flare fittings, it is possible the flares were over tightened at installation. Tightening of those fittings presents a risk that the flares will tear and system can lose a portion or all of the refrigerant charge. Completed moving outdoor unit from blocks to pad
