Our master bedroom AC was leaking, so we engaged Billy AC Servicing & Repair after they were recommended by both my in-laws and my parents. We never mentioned the recommendations to them. Initially, we had a good impression. They were able to offer a next-day appointment and arrived within the timeframe given. During the appointment, they told us the master bedroom unit was very dirty and required additional flushing of the drain pipe using water, as well as a chemical wash of the fan blower and water tray. This added another $200 to our bill. This was the first time we'd been told this was necessary, as our usual AC technicians from Gain City have always just vacuumed the unit with no problems afterwards. We didn't question it at the time, assuming they knew better than us. However, both my parents and my husband's parents were shocked by how much we were charged. When we explained what had been done, they felt we'd been overcharged and that some of the services didn't sound like they had been carried out properly. Another thing we found strange was that they didn't run the AC units after servicing them. Our usual technicians, as well as others we've used in previous homes, have always run each unit for 10–20 minutes afterwards to make sure there are no issues. That evening, we noticed a puddle of water underneath the master bedroom unit and initially assumed it was leftover from the cleaning. We cleaned it up, only for the puddle to return. When we switched the AC on, it continued leaking, despite this being the exact issue we'd called them to fix. This happened on Saturday and we messaged them immediately. We received no response on Sunday and only heard back on Monday afternoon. Eventually, my husband spoke to them and they returned to fix the issue. I've decided to give two stars because the cost genuinely felt excessive and left us feeling like they were taking advantage of two young homeowners who didn't know any better, particularly when the original problem wasn't even resolved after the initial service. That said, I appreciate that they were able to give us an appointment quickly and that they did ultimately come back to rectify the issue rather than disappearing.

Beware of deceptive upselling tactics! I booked a basic multi-unit servicing package with this company. The technicians did the base cleaning, but then immediately used high-pressure scare tactics regarding my outdoor compressor. They claimed it was dirty and would heavily affect the cooling, pushing a steep $150 add-on fee to clean it. While watching them work, I realized the "cleaning" was a complete joke. They did not dismantle the compressor at all; they just sprayed some water and basic chemical over the fully assembled outdoor unit. To try and justify the high price, the technician even showed me a prerecorded video on his phone of dirty water flowing, pretending it was from my own unit. After they left, I checked Billy Aircon's official website. Their own price sheet explicitly states that a non-dismantle compressor chemical wash is only $80 to $100. They use a low base price just to get into your house, then use fake videos and scare tactics to overcharge you by an extra $50 to $70 on the spot. Highly dishonest business model. Avoid!

I would like to feedback my bad experience with Billy Aircon. Had been using their service for few years, all along was good. But recently bad experience and was very disappointed. 28 Feb - came for servicing and do chemical overhaul. Checked no need gas topup. 4 Mar - Suddenly aircon not cooling. Found one of the hose not tighten. 4 May - Came check and say that the outdoor unit coil was not clean well. Need to add $100 for water jet cleaning. 3months ago chemical cleaning did not clean well? Also need to add $100 for gas top up. 4 Mar the hose loose cause the gas to leak. Now I have to top up for mistake they made?

Unfortunate to have to downgrade this review for Billy Aircon. After 3 - 4 years, it seems their modus operandi has shifted from honest and trusty service to downright questionable. I have never heard of chemical wash for split aircon systems requiring complete purging of refrigerant gas in my line of work. The conflicting statements after questioning them on "why the need to purge all the gas and top up for chemical wash" came with two different reasons: (1) My gas was low and need to top up. (2) It is part of Billy Aircon's process to purge and top up. Unfortunely again, this was told to my parents when I wasn't home. My parents know nuts about aircon and let them went ahead and did it. There is no evidence given for (1) when asked. They took photos of the chemical wash process before and after but when I asked for photo evidence for topping up for low gas, they don't do it "unless customer requests". For (2), the need to top up as part of the chemical wash process wasn't mentioned anywhere in their website. While they maintained a very firm posture in their responses on the need to purge and refill gases, it is still not the right procedure, and definitely not one with decades of air-con servicing experience will advise. Maybe NEA will be very interested that this company has a practice from "25 years of professional experience" (from their website) of releasing HFCs into the environment to pollute it every time they do a chemical wash for their customer. Even if the story changed to low gas, topping up of gas is usually done after troubleshooting and the topping up of gas will be not full refill but refilling up to the right pressure. They have the audacity to do such false upselling to a returning customer like myself. I advise anyone to stop being ignorant and falling prey to such practices.

Contacted coolbest Aircon and billy Aircon came instead. Only wanted a $70 general ac servicing but ended up with a bill of $390: $200 gas top-up; $120 outdoor compressor cleaning; $70 general ac servicing. Read all the 1 star reviews and realised these are their typical tactics: very dirty need chemical wash; need wash compressor; need top-up gas. Came on time, said the Aircon is very dirty and suggested chemical wash. I refused. Then say compressor is very dirty need to wash also – I wanted to refuse but he said he's washing already – okay – didn't use the water jet to spray because it wasn't raining and people are doing laundry downstairs so it wasn't very clean. Need to top-up gas too – showed me the manifold gauge – not that I know how to read but okay. There were no issues with my Aircon not being cooling – and other technicians who came to repair and replace the PCB did not mention anything about low gas pressure. As much as you wanted to trust them and give them the space to do their stuff, you need to watch them. You either watch them and be firm with what you want; or get ready for their hard selling and be charged more than your intended services. What's done cannot be undone. Now I just hope there wouldn't be any issues after servicing like the others reviewing that they have leaking problems.

My aircon got problem as the indoor unit can not start the outdoor unit along and has to use another indoor unit to start the outdoor unit. I called Billy Aircon and they sent two people around 7:00pm. They spent almost one hour trouble shooting and tried every steps still have no clue. In the end the service worker told me to either replace out unit power board and control board @ S$1200 or get a second hand outdoor unit @ $1700. As my aircon can still work I declined and paid $50 trouble shooting fee. Realising they do not really know how to trouble shooting Mitsubishi aircon I called Mitsubishi Singapore service centre and they asked us to contact one of their authorised service provider. The service provider came and used 15 min to conducted a system software reset and told us everything should be back to normal and there is no need to replace any thing at all. Then I happily paid $60 trouble shoot fee. The lesson I had here is that when your aircon got problem call your aircon brand centre and get the authorised service provider to trouble shoot. Billy Aircon only understand aircon cleaning service and they have no way to understand how to trouble shooting all brands of the aircons. What makes me confused that they would like to sell you all second hand units to make money and I think by the end you would have to replace your whole aircon system by following their advice./

If more than one tech shows up (3-5 ACs), your budget is blown/ rip off. If more than two techs show up, you're getting hosed.

An aircon breakdown in Singapore’s heat is an urgent issue, but this company took over 24 hours just to reply—an unacceptable delay. After being a loyal customer for years, my family expected better service, especially during emergencies.
