1.5 ton Goodman Heat Pump > putting out cool air while in heat cycle. While, I don't expect you to gauge this accurate but, what is the norm Psi setting low side and High side for this size unit? Thank you!

Accuracy is absolutely necessary!

There is NO normal PSI setting. It changes with every degree of temp difference inside and outside. Recover refrigerant with a recovery machine and charge by ounces/pounds. Do not forget to calculate in your line set. All this info is listed right on the HP.
