    Amazing same-day service on a Sunday night! Our aircon was leaking non-stop, but the team arranged a slot for us immediately. Yen was incredibly helpful and professional. He didn't just fix the leak; he climbed up the ceiling to find the root cause and uncovered a deeper issue we hadn't noticed. He even taped the pipe temporarily for free. Super grateful for Yen's dedication and honesty.

    1 star and that is being generous! I never write reviews but this one I could not let go. Had a contract with this company and honestly wish I never signed it. They promise quarterly servicing and contact every 3 months. Sounds great right? Except they just never bothered. Almost 4 months passed and not a single message. No call, no WhatsApp, nothing. I had to reach out myself to remind them I am a paying customer. When I brought it up the response was cold, robotic and completely unapologetic. The manager S.H. eventually came back to me after speaking to the boss and you know what the big resolution was? A $10 voucher. To spend more money with the same company that just ignored me for 4 months. I actually laughed. These people do not care about you once the contract is signed. The $10 voucher says it all, that is how much they value a paying customer. It feels less like customer service and more like a trap to keep squeezing money out of you. If you are looking for a reliable aircon company in Singapore please keep looking. There are better options out there that will actually show up and do what they promised. Never again.

    We are very sorry for your unpleasant experience. Regarding your last contract arrangement, due to a system malfunction, we are trying our best to notify every customer, but this will take some time. As per your request, we scheduled the last air conditioning cleaning at your new address for today. We are very sorry that we cannot fulfill your request for free cleaning. We also tried our best to negotiate for cleaning the outdoor unit and adding gas, but you refused this compensation. We will further train and improve our service and communication. We apologize again and hope to have the opportunity to serve you again next time.

    Got in touch with Coolest AC service for an emergency service as our regular AC technicians does not respond after office hour. Coolest AC sent their technician down within 2hrs of confirmation and they promptly resolved the issue which would have rendered our bedroom AC system inoperable. Was very impressed with their professionalism and knowledge, thus we decided to engage them again for the installation of a new AC system. The team was punctual and were very patient in listening to our request. They took time to protect our furniture from the installation process. They methodically cleaned up the site after the installation making it an exceptionally pleasant experience. Highly recommended and thank you once again!

    This is a late review but definitely one that needs to be shared. First time engaging this company. My aircon suddenly refused to switch on on 30/12/25. My usual service provider could only send someone in five days, but Coolest Aircon Service managed to arrange a check within about two hours. Really impressed with the service technician. He was clear in explaining what could possibly be the issue and what was needed to fix it. Work was done efficiently, and everything was kept clean and neat. No nonsense, no exaggeration, and no inflated pricing. Will definitely be a returning customer 👍

    Their service man came to check my aircon. My master room aircon is cool, common room is not cool. When the service man come, the common room is cool. But my kid told me his room was hot yesterday, so the service man went outside to check the issue of the condenser. Firstly, he checked there are two red light flashing, he told me it is probably thermistor or PCB problem. Then he said he would consider to change the thermistor. I asked if you change the thermistor, the aircon is still hot, how to do. he said it is probably the PCB problem. He is unsure. After that he went out to check the problem again, suddenly I heard a big loud sound. I thought it is the cover sound, don't put it in mind. later he told me the PCB is faulty and the switch of the box tripped. The incredible thing happened. My whole aircon condenser is totally down. Even worse than he came . This is the first time that I encountered that when you wanted to repair the aircon and the situation of the repairing is worse than it was before. The whole night my kids and I lied down in the living room using the fan to spend. My kids were cried because it was too hot and unable to sleep. Because of kids crying and so angry, I fail to sleep the whole night. The next day, I called other aircon company and consult if it is normal. I was told that the thermistor is impossible to cause the pcb faulty and the PCB faulty is caused by the unproper action. In order to increase the convince, I also consulted Daikin, Daikin replied "unlikely". Unfortunately, the service man keep saying he didn't touch anything and the pcb was burnt by itself. That sounds so funny. Before you come ,my aircon can use but not cool, after you checking, you made the pcb down and you said it is not your problem. This is the first time I heard in my life. Any way, on the second day, I finally contacted the manager of coolest aircon service company and I was told that the solution is to change the whole condenser with a cheaper price 900, because changing the PCB and thermistor more expensive than changing the condenser. I asked my friend and another aircon company, they come and only changed the spoiled thermistor and the faulty pcb . The problem was solved within one hour. The real problem is the thermistor spoiled causing the common room aircon sometimes hot and sometimes cold and is nothing to do with the pcb. Even we connect the old thermistor with the PCB again, the PCB won't be faulty. The PCB is faulty owing to the unproper action by the service man. Everybody knows the PCB is expensive , Coolest aircon quoted me a new PCB SGD700. They make it down and don't take any responsibility and expect I accept 700 to pay to them. Does it sound funny? I requested them to compensate my PCB ,of course they rejected. But you are a reviewer, you can judge by your common sense who is wrong and who is right. According to my experience, would you like to have the same situation with me? If you don't want , you will know how to do. Thank you for reading through my poor experience in here.

    Response from the business

    Dear customer , we apologize for the inconvenience. Our management team has investigated this matter and assigned an experienced colleague to explain the situation to you. My colleague mentioned your air conditioner issue during the inspection, and we offered a solution. If you insist that we caused the damage, we could have arranged for someone to inspect your air conditioner at Daikin, but you refused. We have been actively cooperating to resolve your issue, but we have been unable to meet your requirements. We will provide more rigorous training for all our technicians. We hope you will give us another opportunity to serve you next time. Thank you.

  23. Chiao Min T.

    Very bad customer service..can not answer call and doesn't want to take up the job without providing the reason

    Response from the business

    We're truly sorry you experienced this. We've emphasized several times in your question that an air conditioner inspection is necessary to determine if your issue can be resolved. Without arranging an inspection, we can't guarantee we can help you. We can only ask you to seek help from others since you don't want us to arrange any. We hope to serve you again next time.

    Had a fantastic experience with Coolest Aircon Service! Mr. Yan came over for servicing and to fix a cooling issue — and I was thoroughly impressed. He was humble, respectful, and incredibly detailed in explaining every step of the process. His professionalism and dedication truly stood out. I’ll definitely be signing up for their annual service plan, and I hope Mr. Yan continues to be assigned to my units. He deserves to be recognized for the outstanding service he provided. Highly recommended!

    My aircon was leaking and after “repair” it no longer even works at all (e5 error) and I paid $200 after servicing. Subsequently they mentioned that I need to pay another $250 to replace the indoor PCB and this time they said I had to pay them before they would even come down service the aircon or confirm the appointment? Update: They called me after this review to say that they would waive the deposit and only charge after servicing. Will update again after service. Update: Serviced finished quickly and smoothly and one month warranty was provided for the replaced part

    Response from the business

    Dear customer , our manager was called you and explained all the situation. Hope we can have a chance to solve your issue ,we will work hard to improve our services. So sorry for any inconvenience caused.

    I found this company on Google - out of 3 companies i reached out, I was impressed with Coolest Aircon Service responsiveness. Had an aircon pipe congestion over the weekend, and they fixed it the same day. After-hours charges were higher, but the speed and professionalism made it worthwhile. I've now added an annual servicing contract. Speedy service and reliable.
