"Friendly, Professional, Efficient" Meet the AOS Bath Team!

I want to express my gratitude to Ada Goh and her fantastic installers for their exceptional service.

Ada Goh deserves praise for her responsiveness. I initially reached out to her in 2021, and she guided me through the entire process, helping me choose the right unit which I purchased in 2022 and the installation was only recently completed in 2023. Despite reaching out to them in 2021 and finally installing in 2023, their response time remained remarkably quick.

The installers were extremely cheerful and efficient, completed the installation quickly, and patiently explained how the system works, which was crucial for a first-time user like me.

Thank you for making the entire process incredibly smooth. I highly recommend their services for both home and commercial needs.

This is a review of customer service and installation, I will have to follow up hopefully in 10 or more years when I see how the water heater performs. But both times when I have called up AOS I was in contact with customer service immediately. Extremely responsive, which is a very different experience from my existing water heater company where communication is slow.
My old water heaters barely lasted 3 years before malfunctioning. I had to pay labour on replacements done under warranty, one replacement only last 6 mths so not a reliable brand and the replacements are not covered by a warranty unlike AOS.
Kalam and Shamemul did the installation, they were on time, very polite, offered useful advice and were very diligent. It was not an easy installation because they had to get all the way inside my false ceiling with aircon pipes also in the way. If the heater really last 10 years (or more) this will be my go to brand

The installation process for my Gen 6 water heater was seamless and tidy, thanks to the professionalism and expertise of your technicians, Kalam and Shamemul.

From the moment they arrived, Kalam and Shamemul exhibited a high level of professionalism. They were punctual and ask me how would I like to install. They explain how the system works and addressing any questions or concerns I had.
Before completing the installation, they took the time to test the water heater and ensure everything was functioning perfectly. They physically test the hot water, leaving no room for doubt about the system's effectiveness.

I must also commend your company's Whatsapp services prior the installation, which proved to be efficient and convenient. Whenever I had a question or needed assistance, the responses were prompt and helpful. This level of customer service truly sets your company apart.

I got an AOS 80L micro heat pump recently to replace my electric heater.

My electricity bill has been reduced by a lot and also have never run out of hot water since the installation due to the large tank.

Not to mention my toilet is much cooler due to the cold air emitted from the heater when heating the water.

Highly recommended!

We purchased a heat pump water heater from AOS Bath and have had a positive experience.

They were quite helpful in answering presale questions and explaining the system operation.

The installation was on time and professionally done, and in efficiency mode (the best choice for our needs).

There's a big improvement (reduction) in our monthly electric bills compared to a conventional electric water heater.

I am a return customer of AOSBath.

The most recent purchase was for the heat pump water heater, which promises to be energy efficient. One thing is for sure: I enjoy the cool air exhaust a lot and I find myself sitting/standing near the heater when it is in operation a lot.

1st purchase was for a digital water heater and it worked reliably over 6 years. I have also recommended my sisters to get the same heater and they are happy users as well!
