Your thermostat plays a key role in maintaining comfort while managing energy consumption. By optimising your thermostat settings and adopting a few simple efficiency habits, you can significantly improve how effectively your air conditioning system operates.

Small adjustments can lead to noticeable savings without sacrificing comfort.

Choosing the Right Temperature

Setting your thermostat too low can cause your system to work harder than necessary, increasing energy use and putting extra strain on equipment.

During warmer months, many experts recommend setting the thermostat around 24–26°C for cooling. This range generally provides a comfortable indoor environment while maintaining good energy efficiency.

For heating in colder months, a setting between 18–21°C is typically sufficient for most homes.

Using Programmable or Smart Thermostats

Programmable and smart thermostats can automatically adjust temperatures throughout the day based on your schedule.

For example, temperatures can be slightly higher while you are away from home and return to a comfortable level before you arrive. This avoids unnecessary cooling or heating when rooms are unoccupied.



Smart systems can also learn household routines and allow remote control via mobile apps.

Improving Overall Household Efficiency

Thermostat optimisation works best when combined with other simple efficiency measures:

Close blinds or curtains during hot weather
Reducing direct sunlight helps keep indoor spaces cooler.

Use ceiling fans where possible
Fans improve air circulation, allowing you to feel comfortable at slightly higher temperatures.

Keep air filters clean
Clogged filters restrict airflow and force systems to work harder.

Avoid heat-generating appliances during peak heat
Ovens, dryers and other appliances can increase indoor temperatures during hot periods.

Consistency Is Key

Constantly adjusting the thermostat can actually reduce efficiency. Maintaining a consistent temperature helps your system operate more effectively and reduces unnecessary cycling.

Getting the Most From Your System

Regular servicing ensures your air conditioning system continues to perform efficiently. A well-maintained system responds better to thermostat settings, uses less energy and provides more reliable comfort.

With the right settings and a few simple efficiency habits, homeowners can enjoy a comfortable indoor environment while keeping energy use under control.
