Cool Mode: Reliable Cooling for Perth’s Hot Days
Cool mode is the most familiar setting. It draws in warm indoor air, passes it through a chilled refrigerant coil, and circulates cool air back into the room.
When to use it:
During Perth’s dry, hot days or when temperatures rise above 30°C.
Best temperature:
Set between 24°C and 26°C for efficient comfort.
Energy tip:
Avoid setting the temperature too low, as every degree cooler can add roughly 10 percent to your energy bill.
If your unit struggles to keep rooms cool, explore our installation options to ensure your system size and placement suit your home layout.
Dry Mode: Ideal for Humid Perth Conditions
Dry mode reduces moisture rather than temperature, making it perfect for coastal Perth homes that feel clammy or damp.
How it works:
The compressor cycles on and off, drawing humidity from the air while maintaining comfort.
When to use it:
On humid summer days or in areas like bathrooms and laundries.
Energy tip:
Dry mode uses less electricity than cooling mode, offering comfort with lower running costs.
Fan Mode: Fresh Air Without Cooling or Heating
Fan mode simply circulates indoor air without changing its temperature. It’s ideal for ventilating your home when outdoor temperatures are mild.
When to use it:
On pleasant spring or autumn days when you want fresh airflow.
Best for:
Removing stale air after cleaning or cooking.
Energy tip:
Fan mode uses minimal power and can be combined with open windows for natural ventilation.
Heat Mode: Efficient Warmth in Winter
Heat mode transforms your air conditioner into a reverse cycle heater, one of the most efficient heating solutions available.
How it works:
The unit reverses its cooling process, drawing warmth from outdoor air and transferring it indoors.
When to use it:
From May to September, when Perth mornings and evenings are cool.
Best temperature:
Keep it between 19°C and 21°C to stay warm while conserving energy.
Efficiency tip:
Reverse cycle systems can produce up to three times more heat energy than the electricity they use, making them far more efficient than standard heaters.
If your unit struggles to maintain consistent warmth, check our brands for high performance options from trusted names like Mitsubishi, Panasonic, and Daikin.
Auto Mode: Smart, Set-and-Forget Comfort
Auto mode adjusts cooling, heating, and fan speed automatically to maintain your chosen temperature.
When to use it:
Throughout Perth’s changeable spring or autumn weather.
Energy tip:
Auto mode prevents over-cooling or overheating, keeping your home comfortable with minimal manual input.
If you prefer a system that takes care of the details for you, Auto mode delivers steady comfort and efficiency every day.
Sleep Mode: Night-Time Efficiency and Comfort
Sleep mode helps you rest comfortably while saving power overnight.
How it works:
-
In cooling mode, it gradually raises the temperature to avoid over-cooling.
-
In heating mode, it lowers the temperature slightly to prevent overheating.
When to use it:
While sleeping or resting, particularly in bedrooms.
Energy tip:
Sleep mode runs quietly and conserves power, making it one of the most efficient options for overnight comfort.
Eco or Energy Saver Mode: Lower Bills, Same Comfort
Eco mode moderates compressor and fan speeds to maintain comfort while reducing power consumption.
When to use it:
Daily, during moderate Perth weather or when you’ll be home for extended periods.
Why it matters:
Air conditioning can make up a large portion of energy bills. Eco mode helps reduce costs while keeping your home consistently comfortable.
For even better efficiency, explore inverter models available through Air-Cond Installs WA that adjust output automatically to match your needs.
Turbo or Power Mode: Quick Results When You Need Them
Turbo mode operates at maximum output for rapid cooling or heating.
When to use it:
-
After returning home to a hot or cold house
-
Before entertaining guests
-
When immediate comfort is needed
Tip:
Switch back to Auto or Cool mode once your ideal temperature is reached to prevent excess energy use.
Energy Efficiency Tips for Perth Homes
Every mode can deliver better performance when paired with smart energy habits.
1. Choose the Right System for Your Home
Each home layout is unique. Whether you’re fitting out a single room or multiple zones, our Perth team offers installation options suited to your budget and home design.
2. Select Reliable, Efficient Brands
Not all air conditioners perform equally in Western Australia’s climate. Review our brands to find models known for durability, warranty support, and inverter technology.
3. Service Regularly
Blocked filters or dirty coils reduce airflow and efficiency. Annual servicing keeps your system performing at its best through both summer and winter.
4. Set Realistic Temperatures
Each degree lower in summer or higher in winter can add up to 10 percent to your electricity costs. Aim for moderate settings to maintain comfort efficiently.
5. Improve Insulation and Shading
Using blinds or curtains to block direct sunlight keeps rooms cooler and reduces the workload on your system, especially in north facing spaces.
