Foundation is going in the first part of September and am at a loss as far as who to use for my HVAC. I have talked to a couple companies and recieved bids that aren't to out of line for what needs to be done but am unsure who to use. What questions should be asked to get a feel for who is going to do the best job? I have read all kinds of horror stories of over sized units, poor duct layout, mold and so on. How do you know who to use? Anyone know of a reputable company in the Kansas City area? Sorry if theese are stupid questions. Don't know much about HVAC except that it needs to be done right with the proper load calculations and duct layout. Thanks.
