Reviewers keep coming back to the same picture: clean jet-wash work, careful handling of furniture, and a tidy finish. Many say the units run better afterwards, with stronger airflow and less dust on the fan blades. Most praise names specific technicians, especially Team 3 and Ah Hao. One customer described a mix-up that pushed a job back, but the team apologised and offered a discount. Some reviews are very short, so detail on repairs is thinner than on cleaning.
