I have a customer who want to do a dry ship. The indoor is an American Standard. He wants to install a York dry ship. I told him that since ,they are not the same brand,I have no information to charge the system . Does anyone know of a web site that will address this, or have some info I can down load.
Is there some reason your customer won't choose an AS dry unit? You and your customer are taking a huge risk, as there is no AHRI rating for that combination, you can't guarantee the machine's performance, and there is technically no warranty coverage. If your customer insists and you still want to do the work, at least you have a TXV. weigh in York's recommended charge for your OD unit and lineset (find out if the OD charge includes 15' of lineset) and fine-tune to 10 degrees of sub cooling. Check your superheat too. At least you have done the best you can in a not very healthy situation. All of this is assuming you have cleaned both coils, checked the blower, and done your air flow calculation.
