Imagine having an air conditioner at home or work in a hot summer. You’re probably enjoying nice, cool air all year long.
But what if your AC is blowing warm air during the summer? If your AC is constantly blowing warm air, something is clearly wrong.
Here are 7 common reasons your AC is blowing warm air and not cooling the room as it should. We will also try to answer some common questions about it.
How do you fix it so it cools the room properly again? And what if it keeps blowing hot air, no matter your settings or temperature?
You should schedule a maintenance appointment with Cyanergy, but in the meantime, you’re wondering what the problem might be.
But First, the Basics of an Air Conditioning System
An air conditioning system cools the air inside your home or office, making it more comfortable during hot weather. The system has a few essential components that help it work.
First, there’s the evaporator, which is usually inside the house. This part takes in the warm air from the room and cools it down using a special liquid called refrigerant. The refrigerant absorbs the heat, turning it into a gas.
Next, the compressor, located outside the house, plays a key role. It squeezes the gas from the evaporator, making it even hotter. This hot gas is then sent to the condenser.
The condenser, also outside, cools the gas down by releasing the heat into the air outside. As the gas cools, it turns back into a liquid. The liquid refrigerant then goes back into the system to repeat the process.
Finally, the cooled air is blown back into the room through vents, lowering the temperature. The air conditioner system has a thermostat that you can set to control how cool or warm you want the room to be.
In Australia, air conditioners can cool and heat, making them useful all year round. During winter, the system works in reverse, heating the air inside. Air conditioners help keep homes and offices comfortable, no matter the season.
Types of AC Units in Australia
Several air conditioning systems are commonly used in homes and offices in Australia, each designed to suit different needs and spaces.
One popular type is the split system. This system has two main parts: an indoor unit and an outdoor unit.
The indoor unit cools or heats the air inside, while the outdoor unit releases the heat outside. Split systems are great for cooling or heating one room or a specific area of the house.
Another option is a multi-split system, which works similarly to a split system but can connect multiple indoor units to one outdoor unit. This lets you cool or heat many rooms simultaneously without requiring multiple outdoor units.
A ducted air conditioning system is another common choice. In this system, a central unit is connected to a series of ducts hidden in the ceiling or walls.
The air is distributed throughout the house, making it ideal for simultaneously cooling or heating large spaces or multiple rooms. This type of system is often found in larger homes or commercial buildings.
There are also small portable air conditioners that can be moved from room to room. They are easy to set up and don’t require installation, but they are usually less powerful and only suitable for cooling smaller spaces.
Finally, window air conditioners fit into a window or wall opening. They are more common in older homes and are designed to cool a single room.
Each type of air conditioner has advantages, depending on the space size and how much temperature control you need.
How Does Air Conditioning Work? The Science Behind AC System
Air conditioners come in different shapes and sizes, but all work similarly. They use a special liquid called refrigerant to remove heat from your home or office and blow cool air inside through vents.
Turning on your AC keeps repeating this process until the room is as cool as possible. Warm air inside the house is pulled into the AC and passes through a cold coil filled with refrigerant.
The refrigerant absorbs the heat, turning from a liquid into a gas, and the cooled air is sent back into the room.
The refrigerant gas is then sent to the outside unit, where it is compressed. A large fan pulls in outdoor air, which cools down the refrigerant, turning it back into a liquid and releasing the heat outside. The process repeats to keep the indoor space heated or cooled.
7 Common Reasons Your AC Is Blowing Warm Air
Condenser Coils are Dirty or Blocked
One reason for warm air could be dirty or blocked condenser coils. These coils are in the outdoor unit; the air conditioner can’t cool properly if dust or debris is blocking them.
You can clean the area around the outdoor unit yourself, but it is recommended that you have the condenser coils professionally cleaned at least once a year. Ensure plants and other things are kept from the unit for good airflow.
Refrigerant Leaks
Air Filters are Dirty or Need Replacing
If your air conditioner is set to cool but blowing warm air, there’s a problem. A common reason for this is dirty or old filters. Filters are the first defence against dust and bacteria in the air.
When they get dirty, airflow is blocked, and the system can’t cool the air properly. It can also make the unit noisy and lead to health issues like asthma and allergies.
You can clean the filters by removing the front grille, locating the filter panel, and vacuuming the dust.
You can wash the filters with lukewarm water and mild soap and let them dry in the shade. If that doesn’t help, you might need to replace them, so it’s best to call an expert.
Damaged Compressor
If your air conditioner is blowing hot air even though the thermostat is set correctly, it could indicate a damaged compressor.
If basic maintenance, like cleaning the filters and coils, doesn’t help, it’s time to call an expert. A broken compressor can prevent the unit from cooling properly, and the sooner you get it fixed, the better.
The Return Duct is Broken or Disconnected
Evaporator Coils Have Frozen
The Outside Unit Not Getting Enough Power
What to Do When Your AC Blows Hot Air
Check the Thermostat Properly
Check the Breaker Switch
Most AC systems have both an outdoor and indoor unit. If the indoor unit works but the outdoor one has no power, the AC might blow hot air.
Check the breaker switch. If it has tripped, flip it back to “on” and let the AC run for a few minutes. If it trips again, contact a professional.
Check the Filter
Check for Ice on the Outdoor Unit
If you find ice on your AC, turn it off and let it melt completely. Check the air filter to make sure it’s not causing the problem.
Install a clean filter once the ice has melted, and try turning the AC back on. If it’s still not working, call a professional for help. Avoid picking or chipping the ice, as it can damage the system.
Check for Debris Around the Outdoor Unit
Keep Your AC Running Smoothly with Regular Maintenance
Regular Maintenance: Schedule an inspection and cleaning every spring to catch minor issues before they become big problems.

ACORE Statement on Treasury’s Safe Harbor Guidance
Statement from American Council on Renewable Energy (ACORE) President and CEO Ray Long on Treasury’s Safe Harbor Guidance:
“The American Council on Renewable Energy (ACORE) is deeply concerned that today’s Treasury guidance on the long-standing ‘beginning of construction’ safe harbor significantly undermines its proven effectiveness, is inconsistent with the law, and creates unnecessary uncertainty for renewable energy development in the United States.
“For over a decade, the safe harbor provisions have served as clear, accountable rules of the road – helping to reduce compliance burdens, foster private investment, and ensure taxpayer protections. These guardrails have been integral to delivering affordable, reliable American clean energy while maintaining transparency and adherence to the rule of law. This was recognized in the One Big Beautiful Act, which codified the safe harbor rules, now changed by this action.
“We need to build more power generation now, and that includes renewable energy. The U.S. will need roughly 118 gigawatts (the equivalent of 12 New York Cities) of new power generation in the next four years to prevent price spikes and potential shortages. Only a limited set of technologies – solar, wind, batteries, and some natural gas – can be built at that scale in that timeframe.”

Frequent power outages, unreliable grid connection, sky-high electricity bills, and to top it off, your solar panels are exporting excess energy back to the grid, for a very low feed-in-tariff.
Do all these scenarios sound familiar? Your answer might be yes!
These challenges have become increasingly common across Australia, encouraging more and more homeowners to consider solar battery storage systems.
Why? Because they want to take control of their energy, store surplus solar power, and reduce reliance on the grid.
But then again, people often get perplexed, and their biggest question remains: Should I get a Solar Battery Storage System in Australia?
Well, the answer can be yes in many cases, such as a battery can offer energy independence, ensure better bill savings, and provide peace of mind during unexpected power outages, but it’s not a one-size-fits-all solution.
There are circumstances where a battery may not be necessary or even cost-effective.
In this guide, we’ll break down when it makes sense and all the pros and cons you need to know before making the investment.
In this blog post:
Why You Need Battery Storage Now?
According to data, Australia has surpassed 3.9 million rooftop solar installations, generating more than 37 GW of PV capacity, which is about 20% of electricity in the National Electricity Market in 2024 and early 2025.
Undoubtedly, the country’s strong renewable energy targets, sustainability goals, and the clean‑energy revolution have brought solar power affordability, but the next step in self‑reliance is battery storage.
Data from The Guardian says that 1 in 5 new solar installs in 2025 now includes a home battery, versus 1 in 20 just a few years ago, representing a significant leap in adoption.
Moreover, the recent launch of the Cheaper Home Batteries program has driven this uptake even further, with over 11,500 battery units installed in just the first three weeks from July 1, and around 1,000 installations per day.
Overall, the Australian energy market is evolving rapidly. Average household battery size has climbed to about 17 kWh from 10–12 kWh previously.
Hence, the experts are assuming that 10 GW of new battery capacity will be added over the next five years, competing with Australia’s current coal‑fired capacity.
What Am I Missing Out on Without Solar Batteries?
Honestly? You’re missing out on the best part of going solar.
Renewable sources of energy like solar, hydro, and wind make us feel empowered. For example, solar batteries lower your electricity bills, minimize grid dependency, and also help to reduce your carbon footprint.
But here’s the catch! Without battery storage, you’re only halfway there!
The true magic of solar power isn’t just in producing clean energy; it’s storing and using it efficiently.
A solar battery lets you store excess energy and use it when the sun goes down or the grid goes out. It’s the key to real energy independence. Therefore, ultimately, getting a battery is what makes your solar system truly yours.
Here’s a list of what you’re missing out on without a solar battery:
- Energy Independence
- Maximized Savings
- Better Return on Investment ROI
- Lower Carbon Footprint
- Peace of Mind
Batteries help you to stay powered even during blackouts or grid failures. With energy storage, you don’t have to think of fuel price volatility and supply-demand disruption in the Australian energy market.
Adding a solar battery to your solar PV system allows you to use your own stored energy at night instead of repurchasing it at high rates. It also reduces grid pressure during peak hours, restoring grid stability.
Tired of Australian low feed-in-tariff rates?
Make full use of your solar system by storing excess power at a low price rather than exporting it. Solar panel and battery systems can be a powerful duo for Australian households.
Despite the steady growth in solar, wind, and hydro, fossil fuels still dominate the grid. Fossil fuels supplied approximately 64% of Australia’s total electricity generation, while coal alone accounted for around 45%.
These stats highlight why solar battery storage is so valuable. By storing surplus solar energy, homeowners can reduce their reliance on a grid that still runs on coal and gas.
Enjoy 24/7 uninterrupted power, no matter what’s happening outside.
Besides powering urban homes and businesses, batteries also provide reliable power backup for off-grid living at night when your solar panel can’t produce, ensuring peace of mind.
What Size Solar Battery Do I Need?
While choosing the battery size, it isn’t just about picking the biggest one you can afford; it’s about matching your household’s energy consumption pattern. There is no one-size battery that will make financial or functional sense for everyone.
Nevertheless, if you have an average family of four with no exceptional power demands, you may get by with a 10kWh to 12kWh battery bank as a ready-to-roll backup system.
Well, this is just an estimation, as we have no idea of your power needs, because selecting a battery is highly subjective to the household in question.
With that being said, you can get a good idea of how much power you use on average by analyzing your electric bill copy. Also, keeping track of which appliances you use the most and which ones require the most power will help you.
So, to figure out the ideal battery size for your home, you need to consider three most important things:
-
Your Daily Energy Usage
Check your electricity bill for your average daily consumption (in kWh). Most Australian homes use between 15 to 25 kWh per day.
-
Your Solar System Output
How much excess solar energy are you generating during the day? That’s the power you’ll store to use later rather than exporting.
-
Your Nighttime Power Usage
A battery is most useful at night or during grid outages. So, estimate how much power you typically use after sunset. However, by using a battery, you can also get the freedom of living off the grid.
Sizing Up: The Ideal Home Battery for Aussies!
- For small households and light usage, a 5 kWh battery will be suitable.
- For average Australian households, adding a 10 kWh battery would be enough.
- Large homes and high-energy users will need a 13 to 15 kWh system.
- For full independence, off-grid living, or blackout protection, you may require a larger battery size of 20+ kWh.

How Much Do Solar Batteries Cost?
Previously, you would have to pay between $3000 and $3600 for the battery alone, plus the cost of installation, for every kWh of solar battery storage.
However, you can currently expect to pay between $1200 and $1400 for each kWh of solar battery storage. That is a price reduction of approximately 52%, and things will only get better from here.
Does that imply solar batteries are cheap now? Not really, but the cost is well justified by the pros of having a battery storage system.
Also, while paying for solar batteries, you have to consider many other factors like the type of battery, your solar panel system configurations and compatibility, brand, and installation partner.
These will significantly influence the price range of battery storage.
Is a Solar Battery Worth It | Pros and Cons at a Glance
It’s okay to feel a little overwhelmed while deciding to invest your hard-earned money in a battery.
So, here we’ve listed the pros and cons of having a solar battery to help you in the decision-making process.
Benefits of Solar Battery Storage
- Solar batteries help you become self-sustaining.
- You don’t have to care about power outages anymore
- In the event of any natural disaster, you will still have a power source
- Battery prices are dropping significantly as we speak
- During peak hours, grid electricity prices increase due to high demand; you can avoid paying a high price and use your battery. It’s essentially free energy, as solar generates energy from the sun.
- Reduced carbon footprint as the battery stores energy from a renewable source.
Advantages of battery for the grid and national energy system:
- Batteries support Virtual Power Plants (VPPs). In 2025, consumers get financial bonuses (AUD 250‑400) for joining, plus grid benefits via distributed dispatchable power.
- Grid‑scale batteries like Victoria Big Battery or Hornsdale Power Reserve are increasing system resilience by storing large amounts of renewable energy and reducing blackout risk.
Drawbacks of Solar Battery Storage
- One of the biggest barriers is that solar batteries have a high upfront cost, which makes installation harder for residents.
- Home batteries require physical space, proper ventilation, and can’t always be placed just anywhere, especially in smaller homes or apartments.
- Most batteries, like lithium-ion batteries, last 5 to 15 years, meaning they may need replacement during your solar system’s lifetime.
- While many systems are low-maintenance, some may require software updates, monitoring, or even professional servicing over time.
- Battery production involves mining and processing materials like lithium or lead, which raise environmental and ethical concerns.
Should You Buy a Solar Battery?: Here’s the Final Call!
You should consider buying a solar battery if several key factors align with your situation.
First, it’s a strong financial move if you live in a state where federal and state incentives can significantly reduce the upfront cost. This can make the investment far more affordable.
A solar battery can be especially worthwhile if you value having backup power during outages, lowering your electricity bills, and gaining a measure of energy independence from the grid.
Additionally, you should be comfortable with taking a few extra steps to get the most value out of your system, such as joining a virtual power plant (VPP), which allows your battery to participate in grid services in exchange for modest returns.
Finally, it’s worth noting that rebates decline annually, and early adopters get the most value.
Takeaway Thoughts
Installing a solar battery in Australia in mid‑2025 offers substantial financial, environmental, and energy‑security benefits, especially if you qualify for multiple subsidies and have good solar capacity.
With rebates shrinking after 2025 and demand surging, early movers stand to benefit most.
By helping balance the grid and reduce dependence on fossil fuels, home battery adoption contributes significantly to Australia’s national goals of 82% renewable energy by 2030.
It’s not just about savings; it’s about being part of a smarter, cleaner, more resilient electricity future for Australia.

I just spoke with a guy in the wine industry, and I asked him how, if at all, climate change is affecting what we does.
From his perspective, it’s the horrific wildfires whose smoke imbues (or “taints”) the grapes with an unpleasant flavor that needs to be modified, normally by creative methods of blending.
