Had unit installed on a Tuesday. Salesman promised that the carpenter would be put same day to reinstall attic ladder, he didn't show. Salesman didn't return the next day to check the job ( new unit and revealing all ductwork). I called on Thursday and inquired about carpenter and when work was going to be inspected. Carpenter came out Friday around 10, couldn't finish the job and returned at 4:30 with new trim. Salesman came out Friday to do the inspection and 1/2 of the duct work was not sealed at all..which we paid extra for. Now the installers and salesman have to come out again. What was promised to be a one day job has now turned into six visits. Also called Champion to speak to a supervisor around 10 this am...six hours later and no return phone call! Guess I should have checked BBB before using them
