I am about to bring in a contractor to install central AC in my house. I am in the final stage of a rather comprehensive remodeling effort, all of which was done either by me directly (cca. 85%) or by closely micromanaged contractors. To explain the need for this inquiry, I will admit to being a control freak and never liking to get into any projects into which I do not have the closest insight.
Since HVAC is currently not my specialty as I have never done it, and I generally do not like to confide in contractors (albeit I admit there are some honest ones out there but I am just too much of a control freak to trust a single person without an X number of other opinions), I am looking for a testing methodology/heuristics to verify that he is doing the thing right.
The pump/condenser equipment is the easiest part and I will choose those so I am not worried about that. But the one think I am skeptical about is whether he will do a good job setting ductwork because that is specific to each case. E.g. is there an easy way (online calculator?) for me to plug in the sizes and types and angles of all the ductwork to evaluate his proposal?
Another question is whether there is some device that can measure the flow out of registers when the pump is blowing and to make sure that remote registers get proper air circulation? Also does it make sense to pump up the system (like with black pipes for gas) to make sure there is no leaks along joints anywhere in the ductwork?
Or generally, any checklist/guidelines by which to evaluate and monitor the work my contractor does.
