OK. I've been reading the site for about a week now. I've chosen a contractor that comes with good references, I've chosen a Trane xl14i unit with matching coil for a dual fuel system. This is a system that is high efficiency and doesn't break my bank.
I would like to know what checks should be done after the install to make sure the unit is working to it best capabilities. I feel I've chosen a good firm, but I want to know what need checked after everything is put in. I want to avoid some of the problem others have experienced after the install with air flow, maintaining temperature and humidity problem after the system is accepted and the contractor paid. I know the firm isn't going away-they have been in business over 40 years-I just want the knowledge to know they did it right.
