Austin Engineer Creates Clever Air Conditioning Alternative for Under $60
Austin Inventor Is Stirring Up the Cooling Industry – Big AC Brands Are Not Happy
July 26, 2026 · 4 min read
Austin — What started as a frustration-driven experiment in a
small US garage is now turning into one of the country's fastest-selling home cooling
gadgets. The idea is simple: a compact portable device that cools any room
in under two minutes — delivering real air conditioning performance at a fraction of the
usual cost.
"$800 for an air conditioner? There has to be a better solution."
That's exactly what Thomas Berger (54), an aerospace thermal engineer from Austin, US, asked himself when he looked at the price tags in his local hardware store.
"Every summer it's the same story," Thomas explains.
"A decent window unit costs $800. A portable AC costs even more. And then you're paying $200 to $300 every month just to run it. I kept thinking — there has to be a smarter way to do this."
With over a decade of experience designing thermal control systems for aerospace
applications — the technology that keeps satellite instruments from melting in orbit —
Thomas had the engineering background to do something about
it.
The Idea: Cool the Air Without the Expensive Machine
"The concept isn't complicated," Berger says. "Your room already has air in it.
The key is pulling that warm air in, cooling it rapidly, and pushing it back out — without
the compressor, without the refrigerant, and without the
electricity bill that comes with them."
After several months of prototyping in his garage — testing airflow configurations and cooling chamber geometries, applying the same thermal engineering principles he'd spent his career developing — he built a working prototype.
The result?
Real cooling performance in any room, in under two minutes, without bulky
machines, refrigerant, or expensive installation.
The First Test: The Neighbors Couldn't Believe It
"I set the prototype up in my living room when it was 95°F and pressed the
button," Berger recalls. "Within two minutes, the thermometer read 63°F. I ran it four more
times just to be sure."
What happened next surprised even him.
"My neighbor came over — he's a retired HVAC technician, 35 years in the
industry. He walked into the room, checked the thermometer, looked at the device, and just
went quiet. Then he asked how soon he could have one."
Before long, everyone on the street wanted one.
That prototype became Cooling Ace.
From Garage Experiment to 60,000 Homes Across the US
What started as a personal engineering challenge eventually became Cooling Ace — a patented portable cooling device now used in more
than 60,000 households across the US.
Why Cooling Ace Is So Popular
✅ Cools any room from 95°F to 63°F in under 2 minutes —
tested, repeatable, consistent.
✅ Uses up to 90% less electricity than a window
AC — runs for hours on minimal power consumption.
✅ No installation
required — plug in and press one button. Ready in 30 seconds.
✅
Whisper-quiet at under 40 decibels — quieter than a library, runs while you
sleep.
✅ Completely portable at under two pounds — move it from bedroom
to office to RV without thinking twice.
Who Is Cooling Ace Ideal For?
Cooling Ace is designed for anyone
who wants to:
- Cool a bedroom, living room, or home office without a permanent
AC unit
- Stop paying $200–$300 every month just to be comfortable at
home
- Get real cooling performance in a rental where window units aren't
allowed
- Keep an elderly parent or young child cool without running a full
central system
- Enjoy portable, on-demand cooling
for RVs, garages, or outdoor covered spaces
Why Cooling Ace Is in Such High Demand
With summer arriving earlier and heatwaves hitting harder every year, demand for
Cooling Ace is surging.
"We can barely keep up with
production," Berger admits.
The problem: as a
small US company, Berger cannot manufacture unlimited quantities.
"We
currently have around 3,200 units left in stock. Once they're gone, it will take at
least 8 weeks until the next delivery."
What Makes the Design Different
Berger's approach removes the parts that make a traditional air conditioner heavy, expensive and complicated to fit.
Air already in the room, cooled and returned
Rather than running a refrigeration cycle, the unit draws in the warm air a room already holds, cools it as it passes through, and pushes it back out.
No compressor, no refrigerant
The two components that make conventional units bulky and costly to service are absent from the design entirely.
Runs from an ordinary outlet
There is no compressor load to carry, so the unit draws its power from a standard wall socket.
Nothing to install
No window bracket, no ducting and no contractor visit — which is what makes it an option in a rental.
Light enough to move
Compact and portable, so a single unit can follow you from bedroom to office to RV.
Built on aerospace thermal work
The same thermal-control principles Berger spent a decade applying to satellite instruments.
How It Works
Berger describes the cycle in four steps — and, in his words, “the concept isn't complicated.”
Plug it into a wall socket
No window bracket, no ducting, no installer. The unit works from an ordinary outlet wherever you set it down.
Warm air is drawn in
“Your room already has air in it,” Berger says. The unit pulls that warm air into the intake rather than trying to condition air from outside.
It passes through the cooling chamber
Airflow configurations and chamber geometries worked out over months of garage prototyping do the cooling — no compressor, no refrigerant.
Cooled air is pushed back out
The conditioned air returns to the room. Because the loop stays indoors, there is no exhaust hose to hang out of a window.

A.Questions Readers Have Asked
The points that come up most often about how the unit is built, powered and supplied.
Does it need to be installed in a window?
No. There is no window bracket, no ducting and no contractor visit. That is the reason the article highlights it as an option for renters, where window units often are not allowed.
Does it use refrigerant?
No. Berger's stated design goal was to cool the air a room already contains — “without the compressor, without the refrigerant, and without the electricity bill that comes with them.”
What size space is it intended for?
It is described as a personal and single-room device — a bedroom, a living room, a home office, an RV, a garage or a covered outdoor space. It is not presented as a replacement for a whole-home central system.
Can one unit be moved between rooms?
Yes. Because nothing is fixed to a wall or window, the unit is meant to be carried from room to room and simply plugged in wherever it is needed.
Who designed it?
Thomas Berger, an aerospace thermal engineer from Austin with more than a decade of experience in thermal control systems for aerospace applications. The first working unit was built in his garage.
