My installer is about to startup my new AC system, and I am wondering what is considered "reasonable" to expect from him.
Between reading all the installation instructions and lurking here, I have just enough understanding of how things "should be done" to probably be a total pain to him - on the other hand, I would like things done by the book.
So, where is the line between me wanting to make sure that he does things by the book (or explain to me why he is doing things differently) and him expecting me to trust him as the professional without keeping an eye on things?
For example, if the Goodman instructions say to add 0.6 oz of R410 per ft of lineset above 15 ft before opening up the valves, and he does not follow that, do I question him? If the instructions say to charge on low stage and aim for 5-7 deg of SC and he does something different, what do I do?
Finally, what is normal to expect at the end to know that the system is set up and running correctly - would he give me the measured SC and SH values, ESP, etc?
Would really appreciate your thoughts,
