From my experience installing air conditioners in my HDB, it's absolutely fine to use two different brands like Amyth and Daikin under one roof. In fact, when I pass by my neighborhood, I notice many homes follow this practice. For example, in my BTO in Canberra, the master bedroom and one common room use Amyth aircon, while the living room and kids’ room have Daikin units. What really impressed me about the Daikin system is its streamer technology, which focuses on health protection by killing germs and improving indoor air quality — something I deeply appreciate as a parent wanting the best for my children's health. Choosing multiple brands allowed me to tailor comfort and health benefits across different rooms without any hassle. If you’re considering Amyth Aircon, know that pairing it with another trusted brand like Daikin can offer both reliable cooling and valuable health advantages. This real-life insight might help you feel more confident in your aircon decisions!
