I thinking we need a CODE that demands a proper sequence be followed when installing & also when doing Energy Efficiency work; perhaps with some kind of independent follow-up checking system.
Far too many customers are getting obscene install & service work.
Customer's also need education concerning these procedures.
Wisconsin's (R) governor Scott Walker is implementing a workforce SKILLS training program, with some money even allocated to K-12 students.
We need a very high % of HVAC folks RETRAINED to meet New Higher Standards of Performance!
If our elected reps & us HVAC folks along with everyone in the media would began to explain the tremendous economic stimulus that would occur were there to be this kind of useful high-utility-content on Radio & Television; also, linking to Internet Videos/Audios; plus links to local forums, the economy & jobs would begin to take-off...
Our World is trying to lower our fossil fuel carbon pollution...by investing wisely, everyone can save a lot on their utility bills while helping to solve a multiplicity of the core economic problems facing our World; a mutual win/win/win, reducing budget deficits & prospering everyone...
I fully agree with codes, maintained by the industry. Some that come to mind:
ASME ------ For pressure vessel design, and other joint uses.
ASTM ------ Materials and test procedures ( good posibility )
In my case there is a poor connection from one tech's work, some cryptic notes on what was done and/or what needs to be done by next guy ... poor continuity.
Taking a longer view, the attic access should probably be improved to allow better access to the equipment. This will head off future frustration, even by a more competent crew.

Probably took the stairs out before. With these massive indoor units and standard trusses @ 22 -- no way to get it past the stairs. I have on occasion removed the drain pan/baffles etc... and got them to squeeze through.
They got the new evaporator up the stairs by removing the trim around the ceiling opening.
