Air conditioning tips for renters Australia can help tenants stay comfortable while respecting lease agreements and avoiding expensive property modifications. From choosing portable cooling options to optimizing existing systems, renters have several practical ways to improve indoor comfort throughout the year.
Many Australian renters face challenges when it comes to cooling their homes. Unlike homeowners, tenants may have restrictions on installing permanent HVAC systems or making significant changes to the property. Fortunately, there are still effective strategies that can improve comfort, reduce energy costs, and maintain healthy indoor conditions.
Australia’s climate can be demanding, particularly during summer when temperatures regularly exceed comfortable indoor levels.
Without effective cooling, renters may experience:
✅ Poor sleep quality
✅ Reduced comfort
✅ Higher humidity levels
✅ Difficulty working from home
✅ Increased heat-related stress
Choosing the right cooling approach depends on the property type, landlord permissions, and budget.
Many renters begin by consulting air conditioning specialists to understand available options that comply with tenancy requirements
Not every rental property includes air conditioning, and installing new systems may require landlord approval.
Fortunately, renters can still improve indoor comfort using several practical methods.
Good airflow can significantly reduce indoor temperatures.
Simple strategies include:
✅ Opening windows during cooler hours
✅ Creating cross ventilation
✅ Using security screens where appropriate
✅ Closing windows during peak heat
Natural airflow can make a noticeable difference, particularly during mornings and evenings.
Direct sunlight is one of the biggest contributors to indoor heat.
Renters can reduce heat gain by:
These measures help maintain cooler indoor temperatures without increasing electricity usage.
Ceiling fans and portable fans help improve comfort by increasing air movement.
While fans do not reduce room temperature, they can help occupants feel cooler and may reduce the need for constant air conditioner use.
Many rental homes already include cooling systems.
Common options include:
System Type | Common Rental Applications |
Split System | Apartments and small homes |
Ducted Air Conditioning | Larger houses |
Portable Air Conditioner | Temporary cooling |
Ceiling Fans | Bedrooms and living areas |
Understanding how your system operates can improve both comfort and efficiency.

For larger homes with central climate control, ducted air conditioning systems may already be installed
One of the most commonly discussed cooling guidelines is the “20 rule.”
This rule suggests that indoor temperatures should generally not be more than approximately 20 degrees Celsius lower than outdoor temperatures.
For example:
The goal is to:
✅ Improve energy efficiency
✅ Reduce system strain
✅ Lower electricity costs
✅ Maintain comfortable indoor conditions
Trying to cool a property excessively often increases energy consumption without providing significant additional comfort.
Many renters lower their thermostat more than necessary.
Small adjustments can have a noticeable impact on electricity bills while maintaining comfort.
No. Most air conditioning systems can be set significantly lower than 24°C.
However, this does not mean lower settings are always desirable.
Situation | Recommended Temperature |
Living Areas | 22°C–24°C |
Bedrooms | 18°C–22°C |
Home Office | 22°C–24°C |
General Summer Comfort | 23°C–25°C |
Many HVAC professionals recommend settings around 23°C to 24°C because they balance comfort and efficiency.
Lower temperatures often increase energy consumption without delivering substantially greater comfort.
A common rule of thumb is to select an air conditioning system that is properly sized for the room or property being cooled.
Oversized and undersized systems can both create problems.
Correctly sized systems often provide:
✅ Better comfort
✅ Improved efficiency
✅ Lower operating costs
✅ Longer equipment lifespan

Symptoms may occur when:
These conditions may irritate sensitive individuals and contribute to respiratory discomfort.
Simple steps include:
✅ Cleaning filters regularly
✅ Reporting maintenance issues promptly
✅ Keeping vents unobstructed
✅ Maintaining good household hygiene
Professional air conditioning servicing and maintenance help ensure systems continue operating efficiently
If cooling performance declines, professional air conditioning repair services can help restore proper operation
When permanent installation is not possible, portable cooling equipment can provide additional comfort.
Options include:
✅ Portable air conditioners
✅ Evaporative coolers
✅ Tower fans
✅ Ceiling fans
Portable units offer flexibility because they can move with tenants when they relocate.
During extreme Australian summers, portable systems may struggle to cool larger spaces effectively.
In these situations, renters may wish to discuss permanent cooling upgrades with property owners.

Air conditioning itself does not usually cause wheezing, but poorly maintained systems can contribute to indoor air quality issues that may irritate sensitive individuals. Dirty filters, dust accumulation, mould growth, and restricted airflow can affect respiratory comfort. Regular cleaning and professional servicing help maintain healthy airflow and reduce the likelihood of irritation.
The 20 rule suggests maintaining indoor temperatures no more than approximately 20 degrees Celsius lower than outdoor conditions. This guideline helps improve energy efficiency, reduce system strain, and maintain practical cooling levels. It is commonly used as a general comfort and energy-saving recommendation rather than a strict rule.
No, most air conditioning systems can be set lower than 24°C. However, temperatures around 23°C to 24°C are often recommended because they provide a good balance between comfort and energy efficiency. Lower settings typically increase electricity consumption and may not significantly improve comfort for most occupants.
A common rule of thumb for air conditioning is to ensure the system is properly sized for the area being cooled. Factors such as room dimensions, insulation levels, occupancy, and sunlight exposure all influence cooling requirements. A properly sized system generally delivers better comfort, lower running costs, and improved long-term performance.
