- 5 stars, 10 Aug 2026: I had engaged a 3rd party aircon company to Jet-wash Mitsubishi Starmex system, however after the major servicing I noticed a significant drop in performance, the indoor aircon never reach the temperature set even after on for more than 5 hours. Further more, the outdoor condenser unit was a little noisy than normal/usual and there was no water or condensation in the outdoor unit. The technician had broke my aircon system. I quickly called and engaged Coolserve the next day. Coolserve technicians came early and they did a fantastic job. I would especially like to commend Coolserve technicians 
- 5 stars, 27 Jul 2026: I wanted to thank all coolserve team from service to technician. I've hired them to install aircon for my parents, my bto and my parent in law bto. We have some issues with my parent in law bto. First was aircon placement second was our water heater electrical wire. They are willing to help us settle even by helping out to change water heater wire to a thick wire in short notice! When we offer our Ang bao, they rejected and only asked us to give Google reviews. Thanks Evan and Yong for helping us throughout. And other staffs that came down to help!

Over the years, they have never disappointed me. The service and workmanship have always been consistent and up to standard, which is why I keep going back to them. Recently, I installed 4 units at my place and installer Yong with his team did a great job. The installation was swift, neat, and they cleaned up after everything was completed. I also want to mention Evan, who handled my enquiries. His replies were always quick and strai
