What recent reviews say

Most reviews praise O2's skilled technicians and fair pricing, with several customers noting prompt weekend service and reliable multi-year maintenance. However, a subset report chronic no-shows on booked appointments, delayed replies, and weak after-service support when problems arose, with at least one customer claiming workmanship defects in trunking installation.

Based on limited recent reviews, so treat this as low-confidence.

Watch-outs

STL Air Conditioning

Two of three reviews describe poor installation quality and weak follow-up support. The warranty appears to lock customers into using STL for all future servicing, or coverage is voided. Evidence is limited and spans several years.
