Shoddy Installation - respond

“We were building a new house. I found that installation was lacking care and precision. Venting holes for first floor was "forgotten" until we brought it to their attention. Ductwork not connected properly, piping leading nowhere, ducting coming apart, installing the ductwork in a way that created the necessity for multiple bulkheads which could have been avoided. The company had to be called back many times to repair/finish work. The company has now been sending an employee that seems to know what he is talking about and has made this process easier for now. They have been making the effort to correct problems and open the lines of communication. ”
