- 5 stars, 18 Jun 2021: I had a problem with my air-con unit's circuit board causing it to turn on and off intermittently. Sunny not only diagnosed the problem quickly and accurately over the phone, he promptly came down to do the repair and completed the job in a flash. What a relief! Thank you very much!

- 5 stars, 11 Jul 2020: Sunny has been taking care of our aircon servicing and maintenance for many years. He is also very skilled in changing, replacing and installing new aircon, when necessary. He is reliable, prompt and does a great job always!

They finished cleaning my 4 air cons w
- 1 stars, 11 Sep 2018: Doesn’t stand by their work. Recently came to install an AC and remove the old one. Had reminded them to cap the pipes of the old one and they said yes.

He said put green dye into the AC unit and see if the leaking wall turned green. It did, so it’s completely linked to the AC he had just installed. After looking into the issue, pipe was never capped as he assured me he would do. He then said it wasn’t his responsibility and his job was only to
