The AOS Bath Promise: Friendly, Professional, Efficient
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.
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.

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 months.
Kalam and Shamemul did the installation, they were on time, very polite, offered useful advice and were very diligent.

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. They were punctual and ask me how would I like to install. They explain how the system works and addressed my questions and concerns.
The Whatsapp services prior to the installation are 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.

Smart Water Heaters for SAFRA
When SAFRA Yishun took on a huge upgrade, we worked with them to create an easy-to-use, energy saving heat pump solution.
The water heater from AO Smith is really next gen. It heats up really fast. I love the control panel that tells me exactly how much hot water I have inside."

My new micro heat pump reduced my electricity bill and my toilet is much cooler due to cool air emitted from the heater. Highly recommended!

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!
