Air Conditioning Waterfall Simple, Safe Comfort for Every Age

- What matters
- Reliable heating and cooling with easy controls
Air conditioning in Waterfall needs to handle hot summer days and cold winter nights at the highest point in the Shire. For many families, it also needs to be easy for older parents or grandparents to use, because NSW Health says air conditioning is one of the best defences against heat. Alpha & Omega sets up simple, reliable reverse cycle systems and has worked across the Shire since 1989.

Waterfall FAQs
Waterfall Air Conditioning Questions
What temperature should air conditioning be set to on a hot day?
NSW Health suggests around 26 to 27 degrees, combined with a fan, as a comfortable and energy-saving setting. Turn the system on before the room heats up.
Can family members control the air conditioning remotely?
Yes, with Daikin Wi-Fi on compatible systems. Family can check whether it is on and adjust it from a phone.
What is the easiest air conditioner for an older person to use?
A reverse cycle split with a simple remote, pre-set temperatures and timers is usually the most straightforward. We can set it up and show everyone how it works.
Is reverse cycle good for heating in Waterfall?
Yes. Reverse cycle systems heat efficiently, and modern inverters cope with cold, frosty mornings. We size them for heating as well as cooling.

Before summer, so it is ready for the first hot days. A second check before winter is worthwhile if you rely on it for heating.
