Bringing a newborn home is a beautiful milestone, but the hot Australian weather often leaves new parents feeling a bit worried.

At DEEPCHILL – air conditioning Gold Coast, we want to help you create the perfect environment for your little one. Let’s look at the best ways to manage your cooling system.

At what age can a newborn safely sleep in AC?
According to My Blooming Baby, many parents worry that a fresh, young baby is too fragile for artificial cooling. However, if you have a healthy, full-term baby weighing over 3.5kg, they can safely sleep in an air-conditioned room right from birth. Their little bodies already have enough natural fat to help keep them warm.
On the other hand, if your newborn was premature or weighs less than 3.5kg, they need a bit more time to build up their strength. In this case, it is best to wait until they are 1 to 2 months old before using the cooling system in their room. Always check with your local general practitioner or paediatrician if you are unsure.

Expert-backed tips for the safest AC settings for infants
To keep your baby healthy and support their best development, keep these simple rules in mind:
Set a safe and comfortable temperature
A baby cannot control their body heat as quickly as an adult. The safest room temperature for a. newborn is comfortably cool – usually around 22°C to 24°C, according to Red Nose Australia. A good rule of thumb is this: if the room feels comfortable for you in a light t-shirt, it is perfect for your baby. Just dress them in light, breathable layers.
Keep airflow pointing away
A baby’s breathing system is very sensitive. Direct cold air can dry out their nose and throat, leading to coughs or colds. Never let the wind blow directly onto your newborn. Instead, point the louvres (the little flaps on your indoor unit) up towards the ceiling and keep the fan speed on its lowest setting.
Avoid sudden temperature shocks
Babies do not handle sudden changes in weather very well. If you are taking your baby outside into the heat, turn the cooling unit off a few minutes early. Open the door and let the room slowly warm up. This stops their little bodies from going into temperature shock.
Watch the moisture levels
Cooling units can sometimes dry out the air in your home. This might make your baby’s skin or throat feel dry. Keep your newborn hydrated with regular milk feeds. You can also place a small, safe bowl of water in the corner of the room to naturally add moisture back into the air, or apply a gentle baby lotion to protect their skin.

Vital maintenance checklist for newborn air quality
Clean air is healthy air! To stop dust, mould, and bacteria from reaching your baby’s lungs, you must keep your system clean.
- Monthly check: Gently wash the dust filters in your indoor unit every single month.
- Annual service: Book a deep, professional clean at least once a year to flush out hidden dirt.
