    Very good aircon servicing. Prompt response always. Keep the place clean while carrying out their work. Had been using them for years now, highly recommended.

  2. Lalitha L.

    The worst aircon servicing there is! Do not engage them unless you want to be lied to & be charged a bomb! Very rude also! When you don't agree to their ridiculous up-selling, they get very upset & rude with you & just leave without servicing the aircons! They don't even respect the customer's decision & only wants you to listen to them instead! Worst company ever!

    Review: Turns out they did a terrible job. New technician found out that this company did a poor job of servicing the aircon. Blower was full of dust and they never cleaned properly. Switched to new servicing company.

  5. Leon

    Before and after a chemical wash. They are prompt in replying to my queries. For 1 unit

    I have used Sub Cool Engineering to maintain my 5 air conditioned units in my home for 6 years! I used them also to install and maintain one more unit during my last year of tenancy and remove it and repair walls at the end of the tenancy. They have always done an impeccable job, always delivering consistent quality, very polite and carefull, keeping things clean, with a fair price for service delivered. If I return to Singapore one day I will ask them again for their services, I would look no further, thanks!

    My house 3units aircon trunking replacement job was done recently; they did a good job.

  8. Janice C.

    Have been using this company since 2017, service is good and reliable. Special shout out to Masud, he has been very helpful and approachable as one of the oldest staff I know in the company 👍

  9. Sushant H.

    Highly Unprofessional and shady service provider. Came to house took 1 min per aircon and then my bedroom aircon become faulty just after 1 week of service (never had issue) they said charge 50$ extra for repair now. They won't service, rather damage the aircon. DO NOT INDULGE

  10. Do not recommend. They did a quick job each time they are here and I’m always asked to do chemical cleaning. The manager, admin and the person who did the maintenance is the same person, based on my experience.

  11. Matthew S.

    Bought a quarterly servicing plan a year ago, however they’ve only fulfilled 2 of the servicing cycles with the most recent being in May. No communication or reminder since then. Tried to text a number of times in the past 2 weeks to zero response. Company finally replied asking to go down on Saturday however I was not able to confirm, yet I received calls on the day itself saying I have an appointment which I did not make. Will not be engaging them any further due to poor communication.

    When we first time use their service on Feb 2022, their technician propose to replace the insulation and he guarantee that it will last at least for one year and half after that. This year Oct we call for their service again for chemical wash, their another technician mentioned that we need to replace the insulation again and another filter which cost SGD 370(for one unit), after which they again promised which can last at least one and half year.My husband gave the deposit SGD 50, without knowing that we actually replaced insulation once, I trace back the record found that they did replace the insulation this year Feb, and ask them why we need to replace the insulation in 8 months, they replied there is no record in their system for us, even though we show the full WhatsApp conversation in Feb this year with the same contact number provided on their website still. This techinician and their company contact also never follow up even though they promised would reply me within one day, the message status is sent but ignored as well, why I say so is their WhatsApp status is online but purposely not read my message.

    Good service!

    Did an entire overhaul of aircon system in our home and the units still ended up leaking after spending so much money. The amount of fake reviews here is astounding. Hire them at your own risk.

    Never on time. At LEAST an hour of tardiness to be expected. Technicians do not adhere to clients’ instructions, damaging property with shoddy work. 5 stars reviews from profiles just posting for this company? Obviously FAKE. Update: After seeing the original review, the company promptly apologised and relayed the feedback to their technicians whom no doubt showed their displeasure whilst patching up our home due to the installation of an entirely new air conditioning system that is now running through our walls and ceiling. While I do appreciate the management for following up with the on site works, these were done [replies via whatsapp came in at the later half of the work day] only after many attempts to reach them (one person hotline) and posting this review. Aside from that, there were still many hiccups which occurred within the two days installation. In short, time management and project management were lacking from the on-site technicians and backend support respectively. Agreements were not honoured due to either ‘miscommunication’ or plainly ignored. It was overall an extremely frustrating experience having to deal with both parties from start to end. Not recommended.

    The technicians are professional and honest in informing me of my aircon needs to refill gas which is more appropriate. I appreciate them for that.

  21. kingsley N.

  25. Andy S.

    I’ve used several a/c provider but must say Subcool is the best service ever rendered.

  26. Kent B.

    Good and efficient. Promo code for new customer awesome. Most importantly, they solved my aircon problem.

  27. Wee S.

    Prompt and responsive to query. They gave reasonable price packages for the aircon and other supplementary services. Highly recommended :)

  28. FY W.

    Booked my aircon servicing appointment with them last week. They called before arriving. Experienced technicians. Explained patiently on my aircon condition. They did a good job! Will book again.
