The project was supposed to have been finished in three days, but it actually took five months to complete. They didn't tell me that the ductwork going through the dining room and my son's bedroom would be exposed, they mistakenly disconnected my doorbell and my Internet cable, and they left a hole in my roof's soffit. There were several other issues that arose during the installation such as creating a hole in one of my living room's walls. They did address these issues when I brought it to their attention the first time, but I had gone through such frustrations with them that I didn't push them to do as much as they should have. As an example, they merely patched the hole in the living room but didn't bother to paint over the repairs. Additionally, certain parts of the house aren't receiving enough airflow due to poor ductwork, the air conditioner is using more energy than it actually should, and the ventilation is running at times when it shouldn't be. At this time, the company is telling me that I have to pay for any additional work they do to resolve these problems since it has been one year since the work was completed. Furthermore, I had issues with one of the men working on the project. I asked that he avoid playing country music in the house because I'm not a fan of it, and he said he would stop playing it if I didn't play my music. I found this to be disrespectful and unprofessional since it's my house, but I didn't want to rock the boat because he seemed to be the only who knew what he was doing. The workers also showed up consistently later than scheduled during the project, and the lady in the office was a bit gruff and disrespectful when I called to ascertain when I should expect them to be out. She gave me a time, and I asked if she was referring to a window period or if the men would be at the house at that time specifically. She then stated not to make a big fuss of things and that I should have realized that she was giving me a timeframe as opposed to a specific arrival time.
