The estimator was quite accurate in what was needed for my old house that is divided into three apartments. When I realized as the installation was beginning that the apartments needed separate outdoor units to avoid conflicts between one person wanting heat and another wanting AC, the estimator quickly reconfigured the equipment without changing the price even though the original equipment had already been ordered. The installers came exactly when they said they would, were fastidious about clean up and thorough about instructions. They navigated some challenging location issues (low hanging power lines, tight crawl spaces, very high 2nd floor ladder requirements) without complaint. Passed city inspection with no problems.
