The Smarter Way to Cool Your Home
Faster cooling. Lower bills. Zero installation.
Cold Air in 60 Seconds Flat
Powered by FrostCore™ heat-exchange technology, Coolzy pulls warm air through dual cooling coils and pushes back a steady stream of cold in under a minute.
Set it anywhere from 24°C down to 16°C, and it holds steady, even when it’s 40°C outside*. No more sticky 2am sheets. No more rooms that feel like ovens by lunchtime.
Slash Your Energy Bills
Ducted aircon wastes 40% of its power cooling empty rooms. Split systems lock you into a £2,000 install before you feel a single degree of cold air.
Coolzy runs at low voltage and cools only the room you’re using – for cents per hour. No installer to book, no ductwork to maintain, no whole-house bill at the end of the month.
Landlord-Approved Cooling
If you rent, you know the rule: no holes, no permanent fixtures. Which usually means no aircon and another summer of fans pushing hot air around.
Coolzy changes that. No window kit, no wall mount, no electrician. Open the box, plug it into a standard outlet. Move it from room to room in two minutes or take it with you when you move out. The same unit that cooled this place will cool the next one.
Filters Air
It purifies the circulating air, leaving it not only cooler but fresher too. Forget those runny noses with regular A/Cs!
Optimal Humidity
Too dry air itches airways, but too much humidity is not good either. Coolzy strikes the perfect balance to make you feel good.
Adjustable Cooling for Comfort
No such thing as too cold or too warm. Pick the desired level and you’ll enjoy the perfect chill in your own space.
Stay Cool in 3 Easy Steps
1
Plug It In
Place the unit where you need comfort most, then connect it to a power outlet.
2
Choose the Mode
Use the touchscreen or remote to select one of 6 different modes for the perfect climate.
3
Sit Back & Relax
Enjoy instant comfort in just seconds, with precise temperature control right at your fingertips.

Sarah
I hated the idea of getting an air con installed. Too expensive and way too much hassle. This was literally plug in and go. No tools, no tradies. The remote makes it so easy to adjust from the couch. Couldn’t be happier.
Jess
Our rental gets unbearably hot in summer, and the landlord won’t allow a split system. We tried fans, but they just blew the hot air around. The Coolzy has been brilliant so far! It actually cools the lounge in minutes, and I can wheel it into the bedroom at night. Whisper quiet, too, I barely notice it running.
Daniel
We were spending a fortune on power bills running the ducted aircon just to keep one room cool in summer. Now we just use the Coolzy in the living area. It cools down quickly, and the bills are much lower. Works just as well in the bedroom at night too. We’re really happy with it.

No more sweaty nights
I used to dread going to bed in summer because the heat was unbearable. With this, I can actually sleep comfortably and wake up feeling refreshed instead of sticky and tired.

Cut my power bill noticeably
Our old ducted system costs a bomb to run and we only needed the lounge cooled most nights. I saw an ad for this and thought, what the heck, might as well. Happy with the purchase so far. The lounge stays comfy without sending the power bill through the roof.

Very easy to move between different rooms
take it from my home office during the day into the bedroom at night. No fuss at all. Saves me from buying two separate units for each room which would’ve cost a fortune and taken up so much space

Great for rentals
We rent and couldn’t put a proper air con in. This solved the problem straight away. No installation, no arguing with the landlord, and now the whole flat is comfortably cool.

Finally warm in winter
Our place is freezing in winter and little heaters never did much. This actually warms the whole living room quickly, so the kids aren’t sitting there in hoodies and blankets every evening. Makes a massive difference.

Wish I bought it sooner
I kept putting it off thinking it would be complicated. Turns out it was literally plug it in and enjoy. My place is so much more comfortable now! Should have grabbed one ages ago.

Sleeping better than ever
I used to wake up three or four times a night sweating through summer. Since getting the Coolzy, the bedroom stays at a steady temp and I actually sleep through till morning!!
Kylie R.
Verified customerNo dramas with setup
Mate, I pulled it out of the box, plugged it in, and that was it. Took all of two minutes and I had cool air pumping into the lounge.
Jack M.
Verified customerKeeps my flat liveable
My little apartment heats up like an oven in summer. I couldn’t put in a proper air con, so I felt stuck. This unit has completely changed that. Now I can relax on the couch without sweating through my clothes. It like finally having control over the place.

Big savings on power bills
We were spending a fortune on ducted air, even though we only used two rooms most nights. Our bills have dropped heaps since we switched to this. Cheaper and smarter. We cool or heat only where we need it.
George S.
Verified customerLove how portable it is
I move it around depending on where I am home office during the day living room in the evening bedroom at night. It’s light enough that I don’t even think twice about it
Tara W.
Verified customerGreat for the kids
Finally we don’t have to stress about it being too hot or cold in the kid’s room. They even change the settings themselves if it gets too hot or cold.
Adam L.
Verified customerQuiet and reliable
I was worried it would be noisy like other portable units I’ve tried, but honestly it’s quieter than the pedestal fan we had before. I can read or watch telly without it bothering me, and it just does the job day after day.

Verified customerShould have bought one ages ago..
Id been on the fence for ages because I thought it wouldnt be powerful enough. Well I was wrong. Within 10 minutes it cooled the whole living room. Should have pulled the trigger months ago.

“Coolzy Was Rated As The Best AC For Room Climate Control In 2026.”
“Cools any room faster than I expected”
Licensed HVAC Technician
Most portable units I come across are underpowered, loud, or struggle to hold temperature. Coolzy’s different – it pulls a room down quickly, keeps it there, and needs no installation to do it. For renters, small homes, or anyone wanting to skip a split system, this is the unit I’d recommend.

Frequently Asked Questions
How does the cooling system work?
Coolzy uses our FrostCore™ heat-exchange technology to deliver fast, efficient cooling. Warm air is drawn in through the vents and passed over dual cooling coils, where the heat is absorbed and the air is rapidly chilled before being pushed back into the room. Condensation evaporates inside the unit, so there’s no drain hose, no water tank, and no messy setup.
What modes does Coolzy have?
Coolzy comes with 6 power control modes, so you can match the cooling to exactly what you need. Choose from Cool, Heat, Eco, Timer, Fan, and Swing – each one adjusts fan speed, temperature, and power use to suit the moment.
Does it require professional installation or setup?
No. Coolzy is completely plug-and-play. Just place it where you need it, plug it in, and you’re ready to enjoy cool or warm air instantly. No hoses, drilling, or installer required.
How large of a room can it cool?
Coolzy is designed for rooms up to 51 m², depending on insulation and layout.
Does it work in humid conditions?
Yes. Coolzy is built to handle warm, humid environments – the FrostCore™ system actively pulls moisture from the air as it cools, leaving the room feeling drier and more comfortable, not damp or sticky.
Does it come with a remote control?
Yes. Every unit includes a remote control, so you can adjust temperature, modes, and fan speeds without leaving your seat.
Can I move it between rooms?
Absolutely. Coolzy is lightweight and portable, making it easy to move wherever you need comfort most.
Is it noisy?
No. Coolzy is engineered for whisper-quiet operation. It’s much quieter than traditional AC units or fans, making it ideal for bedrooms, home offices, or study spaces where peace and quiet matter.
Will it increase my power bills?
Quite the opposite. FrostCore™ is engineered for high performance at low voltage, meaning you get cold air faster while using less power than a traditional AC. There’s also no installer to pay, no ductwork to maintain, and no expensive split system to buy upfront.
Can I leave it running overnight?
Yes. Coolzy is safe for overnight use, with built-in protections against overheating, overload, and short circuits. Switch to Sleep mode for the quietest, lowest-power operation through the night.
What is the warranty?
Every purchase is backed by a 1-year warranty plus a 30-day money-back guarantee, so you can try it risk-free.
