My new home is in the HVAC rough in stage now. Having 4 Nutone 23 SEER IQ Drives installed. Overheard the HVAC technician say that this was the first IQ system he has installed and I asked him about that and he said he had been to the training classes and that it wasn't much different from a standard install.

Those that have installed them before, Is there anything I need to look for or be aware of while it is still in the rough in stage to make sure I will get all the benefits of the higher efficiency and comfort from our new system. Hate to feel like I am going behind my builder and HVAC contractor's back but it is my retirement home and I do owe it so myself to make sure I double check.
