This morning (Fri 21 Nov 2025) my AC unit in Brunswick East’s apartment block was serviced by your employee, Josh. Both my husband and I are very impressed with the man. He was punctual, courteous, competent, quick, neat, careful in his duties and genuinely pleasant in course of our interactions. He displayed the highest level of professionalism. Thank you.
