Split system air conditioners and ducted systems are great for heating homes during the cold winter days and nights. But it can be difficult finding the right temperature for keeping you and the family from experiencing the chilly outside temperatures without breaking the budget in terms of energy bills.

That’s why the team at Upside Down created this helpful guide for helping you achieve the optimum temperature for air conditioning and understanding why it’s important to make it happen. Here’s what you need to know.

Why Finding the Right Temperature is Important

Finding the right air conditioning temperature is vital for more than just comfort. The ideal settings will help keep running costs to a minimum and ensure the health and wellbeing of the family. Here’s what the optimal temperature can do for you:

Reduce Asthma Attacks

Winter can be difficult for people with asthma, as the cold, outdoor air or humid indoor conditions irritate and constrict the airways. A suitable air conditioner temperature can improve conditions and help reduce the likelihood of these attacks.

Prevent Virus & Diseases

Cold temperatures can reduce the response of an immune system, making it more challenging to fend off viruses like the flu and common cold – Even COVID-19. This is why you’re more likely to have a runny nose and cough during winter. Stay warm, and you are less likely to get sick.

Limit Overheating

Overheating is often an unforeseen consequence of setting the air conditioning too high. The home might be toasty warm, but thick pyjamas and bedding also help the body generate heat, and need to be considered so that you don’t overheat in bed. Dehydration, exhaustion and heatstroke are all undesirable consequences of overheating.

Decrease Electricity Bills

The harder an air conditioner works to heat or cool a home, the more energy is consumed in the process. However, it’s possible to find a happy medium that’s both comfortable and won’t cost you a fortune on quarterly bills.

Help the Environment

The more electricity consumed by an air conditioner, the more greenhouse gas emissions are produced, polluting the atmosphere and contributing to global warming. An eco-conscious household won’t want to push the air conditioner to max settings.

Consider the above factors, and it’s easy to see why it’s essential to set the temperature for air conditioning just right.

  • I didn’t realise it can help reduce asthma attacks


  • I intend not to use a heater Yes I may be crazy not using one but I just cannot afford the cost


  • Haha the hotter the better! I can never seem to warm up in winter

    • Yes I got them all sweating at home as the heater is always full on

  • Those are important points, but I was hoping for a temperature guide to compare with what we do.

    I actually love winter!!! I can’t stand summer. No matter what, you just can’t get comfortable and I hate that feeling you get when you get out of the shower and it’s so hot you’re already sweating – yuck!!!!!


  • We live in a cold climate and don’t heat the bedrooms at all or even the house of a night. It’s plenty warm enough with PJs and blankets. We have the air con on at 18-21 of a day, depending how cold it is, but we always wear warm clothes inside.


  • I’d love reverse cycle. So convenient.


  • Great tips. We live in Queensland and don’t heat much in the winter

  • Very useful and in time for winter thank you! It definitely happens to me that I put it too high and then find the kids sweating. It’s just hard to know how they are feeling specially young kids that don’t communicate. Quite hard keeping the e temperatures with a long 1 storey house as well
