Typically if I remember right, you'll have about a 30 degree drop across the evaporator, so 100 degree air coming in, will drop to 70 degrees coming out. Eventually it'll drop down to a comfortable level. Also R134A isn't as efficient as good old R12.

If you have a sight glass, you can back-yard it and add refrigerant untill the bubbles stop. They should have given you the correct amount for the charge for that system or some specs as far as superheat temps ect.

Do you have tinted windows? Otherwise the heat gain my be greater than thee unit can handle.

You can do anything you want to......ONCE!

Hale Boppe comet shot off my roof. See you can use 100 iso at night with no flash!
