Welcome! Here are some tips for using this forum.
Trying to treat a problem AC two air handlers set to one condensor with tees.
That when left on overnight, trips the breaker. when running in the day pressure reads 162/58. Cleaned coils no airflow obstructions. cools the space fine. The condensor may be oversize. I would suspect that the breaker trips when ther is some return liquid due to cooler nights.
two quick fix solutions? Add a condersor fan control to keep pressure higher. or Add a bypass to the compressor and set it to raise the pressure enough or is there a self regulating valve that can do this with prescision. Whats your take on this??
