Learn simple ways to keep your cool room stable, energy friendly and dependable through every season.

Navigating the high tide of rising energy bills has become quite the challenge for many Aussie homeowners, including ourselves. It’s a bit of a shock to see how much our air conditioners are cranking up the costs, sometimes chewing through nearly 40% of our home’s electricity during those warmer months.
In our quest to keep both comfort and savings in check, we stumbled across something pretty useful – SEER ratings. This yarn is all about unpacking what SEER ratings are and how they can be your best mate in saving a few quid while doing your bit for the planet too.
Let’s get stuck into it!
SEER, or Seasonal Energy Efficiency Ratio, measures the cooling output of an air conditioner during a typical cooling season.
It’s calculated by dividing the total cooling provided by the energy consumed in watt-hours.
SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently an air conditioner or heat pump cools your home over the cooling season. The ratio is calculated by dividing the cooling output of the unit, measured in British Thermal Units (BTUs), by its energy usage in watt-hours.

A higher SEER rating means the unit uses less energy to cool your house, leading to lower electricity bills and significant cost savings. Upgrading to a more efficient cooling system with a high SEER rating can be a smart investment for homeowners looking to reduce their energy costs and improve their home’s comfort.
Let’s dive into how SEER is calculated next.
Now that we understand the significance of SEER ratings, let’s delve into how these ratings are calculated. The SEER value is determined by dividing the total cooling provided over a typical cooling season by the total electric energy input during the same period.
This calculation allows for an accurate measure of an air conditioner’s efficiency in converting energy to cooling. It provides homeowners with a clear indicator of how much electricity an air conditioner will consume to deliver a certain amount of cooling.
Understanding this calculation helps you make informed decisions when selecting an air conditioning unit, ensuring you choose one that aligns with your energy-efficiency and cost-saving goals.
Understanding the difference between SEER and EER is crucial for us as homeowners aiming to save money on our energy bills while keeping our homes comfortable. Both terms relate to the efficiency of air conditioners but serve different measurement conditions.
Here’s a straightforward comparison in an easy-to-understand table format:
| Aspect | SEER (Seasonal Energy Efficiency Ratio) | EER (Energy Efficiency Ratio) |
| Definition | Measures the cooling efficiency of an air conditioner over an entire cooling season. | Measures the cooling efficiency of an air conditioner at specific operating conditions. |
| Calculation Conditions | Based on a seasonal average temperature. | Calculated at a fixed temperature of 35°C (95°F). |
| Measurement Unit | BTU (British Thermal Unit) per watt-hour. | BTU (British Thermal Unit) per watt-hour. |
| Importance | More relevant for assessing seasonal efficiency and potential savings over time. | Useful for comparing peak operation efficiency, especially in high-temperature areas. |
Both SEER and EER ratings play important roles in choosing the right air conditioner for our homes. While SEER gives us a broader picture of efficiency over a season, EER tells us how efficient the unit will be at its hardest working point. Making an informed decision means weighing both these ratings together, alongside other features and pricing, to find the unit that best suits our needs and budget. This approach helps us maximise our energy savings and contribute to a more sustainable environment.
Investing in a high SEER rated air conditioner can bring several benefits:
Upgrade to high SEER rated air conditioners for lower electric bills, tax credits, and enhanced cooling efficiency. Maximise

energy savings while reducing your carbon footprint. Read more to learn about cost-effective air conditioning options.
High SEER rated air conditioning units lead to lower electric bills. These systems consume less energy, reducing the overall cost of cooling your home. Upgrading to a higher SEER rating can result in substantial savings on your utility bills over time, making it a valuable long-term
investment for homeowners. Improved energy efficiency significantly impacts electricity costs by minimising the power required for climate control, ultimately resulting in cost-effective and environmentally friendly cooling solutions.
We can benefit from tax credits and rebates on high SEER air conditioners. These incentives encourage energy-efficient choices and can significantly lower upfront costs.
High SEER rated air conditioners deliver enhanced cooling efficiency, ensuring your home stays comfortably cool while using less energy. This means lower electricity bills and reduced environmental impact, making it a smart financial and eco-friendly choice for homeowners.
Upgrading to a high SEER unit maximises energy efficiency in your HVAC system, ultimately saving you money on cooling costs and contributing to overall energy conservation efforts.
It’s a cost-effective way to keep your home comfortable while being mindful of your expenses and the environment.
By choosing air conditioners with high EER ratings, we can enhance cooling efficiency while simultaneously reducing our carbon footprint. These energy-efficient units consume less electricity, consequently decreasing the demand for power generation, which in turn lowers greenhouse gas emissions and contributes to a healthier environment.
Upgrading to high EER rated air conditioning units not only saves money on energy bills but also plays an active role in sustainability and conservation efforts.
Homeowners should prioritise investing in appliances that align with environmental responsibility such as higher EER rated air conditioners. This proactive approach benefits both households and the planet by reducing overall energy consumption and environmental impact.
To budget for high SEER units, consider the long-term cost savings from reduced energy bills and potential tax credits. Research available incentives such as rebates or special financing options that can help offset the initial investment.
Look for models with durability and energy efficiency to maximise savings over time. Prioritise features that align with your household’s needs while keeping an eye on the potential impact of higher SEER ratings on electricity costs.
When considering high SEER units, assess their financial benefits in line with your specific cooling requirements before making a purchase decision. With careful planning and consideration, investing in a high SEER air conditioner unit can result in substantial long-term energy savings while ensuring optimal home comfort through efficient cooling solutions.
We understand that high SEER rated air conditioners can be a significant investment, but the long-term benefits far outweigh the initial cost. Here’s what you need to know to overcome any objections:
Understanding SEER ratings for air conditioners is crucial for saving money on energy bills. Choosing units with high SEER ratings can lead to lower electric bills and offer tax credits and rebates.
High SEER ratings not only enhance cooling efficiency but also reduce your carbon footprint. When budgeting for AC units, consider the long-term benefits of higher SEER ratings. Overcoming customer objections about the initial cost can be done by highlighting the financial benefits in the long run.
