- 1 stars, 26 Jun 2025: The after service was really bad. My air con flap was loose after the service and we tried contacting them and they mia us. After multiple attempts then did they reply and said they would come over. However for 3 days which they liased with us to come, they failed to turn up and wasted our time waiting for them. Totally unacceptable. No one deserves such service.
- 1 stars, 21 Oct 2022: Dear friends don't use the O2 aircon they no response your calls and msg and you take yearly contract (YCM) they no response and Dear Tamilnadu and other workers don't join the company they no pay properly your salary...
- 5 stars, 17 Oct 2022: I am Francis as ERA Agent and having more professional aircon service providers. But I would like to use only O2 Aircon Engg for my own house. The existing aircon compressor was failure due to wear and tear getting old. O2 professionals identified the issues and gave two suggestions. I decided to replace new aircon fan coil units & compressor only and remain same piping. O2 Aircon Engg quoted reasonable price and replaced it on the same day to settle the issues. Really appreciated & recommend O2 Aircon Engg for your first choice.
- 5 stars, 12 Oct 2022: Just recently I use O2 service to change my house aircon using back same pipes. O2 was professional in sending team for a site visit without any obligation. The team was confident to install FC without touching the false ceiling which was very good. And they delivered.
