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.

I recently reinstalled my existing AOS Bath heat pump water heater after completing my home renovation. During the installation, the team discovered that the unit had sustained some damage.
Moez and Iliias went the extra mile to help salvage and reinstall the existing unit, demonstrating excellent technical knowledge, professionalism, and a genuine commitment to helping their customer.

The installation team, consisting of Pankaj and Sumon, was outstanding. They were not only highly professional but also polite and articulate in their English. They meticulously explained every step of the installation process before proceeding, which made me feel at ease.
Moreover, they maintained a tidy workspace, cleaning up as they went along, which I greatly appreciated.

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!
