    Rotolocks

    Dealing with large scrolls, 15 ton. I need to take a poll. Would you prefer sweat or rotolock terminations on the compressor? We presently use rotolocks, manufacturing would rather braze.

    When you suspect the air coil, it's good practice to disconnect the fan motor and freeze the coil. You can then see which end tubes are not freezing.

    Yes, we will be controlling the flow through the coax to satisfy a discharge air temp sensor. Not really so difficult. Reheat is inherently not efficient, so the drop in EER can be justified.
