The CoolBot turns most brands of off-the-shelf, window-type air
conditioning units (purchased separately) into a turbo-charged cooling
machine. Transform a (highly-insulated) room into a walk-in cooler,
keeping products fresh and temperature controlled cool to 35°, even in
the heat of summer. Truly DIY. No tools or electrical knowledge required. Installs in 2-3 minutes on (many)
major brands of window air conditioning units purchased separately,
including LG, Danby, Haier, Samsung and GE.
Note: You must use StoreItCold sizing charts
and recommended air conditioners brands or the CoolBot won't work. Please see the Specifications Tab for more info.
CoolBots save customers up to 80% on upfront and installation costs
compared to standard walk-in cooler compressors, and lower monthly
electricity bills as well. CoolBots are recommended by many University extension

What Air Conditioner Do I Need For My Walk-In Cooler?
Great question! There are 3 elements to consider:
- A/C Size in BTUs
- Unit type – window unit or mini split. Please note A/Cs must have digital controls to work with the CoolBot.
- A/C brand
First, let’s start with A/C size – we’ve put together a handy chart
to help. This chart shows the size (measured in BTUs) of the air
conditioner you need based on (1) the dimensions of your cooler and (2)
the temperature range you’ll be storing your products at. Please
note that these A/C sizing suggestions are based on a cooler insulated
to at least an R25 insulation value and opened no more than 6 times per
*Assumes an airtight cooler with an 8′ ceiling, R25 Insulation and less than 6 openings per hour. Please fill out our Cooler Construction Advice Form for questions
A/C Sizing for Particular Uses:
Restaurants using CoolBots need
their food to be below 40°F (4.4°C) to be food safe. Most set it on
38°F (3.3°C) to give themselves a buffer. If you prefer to be
consistently at 36°F (2.2°C), upsize at least one size. Upsize two sizes
if the cooler is opened once every 10 minutes. Another benefit of
upsizing is that it will give you faster cool-down times.
Wine Cellars built with CoolBots, Cheese Caves using CoolBots or folks using CoolBots for meat curing, often
only need to be at 50°F+ (10°C+) and can use smaller air conditioners.
They can also get away with a lighter insulation, R14-16 is fine for
coolers kept at those higher temperatures.
Florists using CoolBots or convenience stores with display coolers
(glass doors) need to upsize at least two sizes. Glass leaks a lot of
cold given its low R value. Florists should consider upsizing one level
anyway to allow for a lower fan speed that’s even less airflow to dry
out the flowers. CoolBots are highly recommended by industry groups for
Florists and flower growers.
Brewers using CoolBots for Lagering and anyone using CoolBots to keep their coolers below 38F require
insulation on all surfaces, walls, ceiling and floor to an R value
of R25-R30. Be sure to keep the room air tight, including a tight seal
around the door.
Type of A/C
First, in order for the CoolBot to function, your A/C must have a digital display.
There are a few different types of air conditioners, and we have
found that certain ones work better than others. In order from the best
- Durable and efficient, the window unit is our preferred type of A/C.
Whether it is installed in a walk-in cooler, truck, trailer or boat,
the window unit has the best performance. Commonly available in the U.S.
and the best priced A/Cs, these units will work even if you’re
installing the A/C in an 11 inch thick wall.
- If you lack the space for a window unit, mini-splits work
wonderfully with the CoolBot and are a great option. International
customers often find these units to be more readily available and
affordable. In the U.S., mini-splits can cost twice as much as a window
unit, but they’re also more efficient. Consumers may notice energy
savings since the mini-splits are more efficient.
- So far, the CoolBot has worked with almost every brand of
mini-split. Panasonic, Midea, and Senville mini-splits have been
difficult to work with, so we recommend avoiding them. The Mitsubishi
“Mr. Slim” model has also given customers trouble, but other Mitsubishi
mini-split units work well. Ask the mini-split manufacturer what the
minimum outside air temperature for efficient functionality, and compare
that with your climate. Even if the CoolBot works perfectly with your
air conditioner, if it’s a brand that stops working when the outside
temperatures fall below 40°F (4.4°C) and you need the cooler to be
running over the winter, you will be unhappy.
Through Wall Unit
- Through-the-wall units tend to be twice the price of window A/Cs and
seem to have (slightly) more electrical problems than window units.
There are no serious or unworkable problems, but they are unnecessary
annoyances. If you already have a through-wall unit, don’t hesitate to
Portable Air Conditioners
- Instead of sticking out the window, these units have a flexible
piece of pipe that looks like a dryer and fits out a small window.
- DO NOT PURCHASE A PORTABLE A/C FOR USE WITH THE COOLBOT – these
units bring too much warm air into the cooler, only get down to 50°F
(10°C), are more expensive, and consume more electricity. Please use one
of our recommended options instead!
Brand – Top Recommended Window Unit Brands
Now that we have the best type of A/C figured out, we will highlight
the best brands.1,000’s of people use one of these recommended brands’
window units: LG, Danby, and Haier. Among them, LG is our favorite due to easy installation and consistent performance with the CoolBot.
These brands are generally available at Amazon.com, Home Depot, Lowe’s,
Walmart and Sam’s Club. If you have trouble finding a specific model,
call your nearby store and they can usually order it for you, or check
LG: LG is our top preferred
brand! We have thousands of people using LG A/Cs going back all the way
to 2006, and most of them are still running strong 8 years later!
Danby: Danby (manufactured by Whirlpool) offers
great air conditioners. They were previously only available in Canada,
but are now in the US too. Any Danby model (from after 2011), so long as
it has a digital display, will work with the CoolBot. Avoid pre-2011
models due to electrical problems.
Haier: Many customers have successfully used Haier
units with CoolBots for years. Sometimes they can be a bit
cheaper. Starting in 2010, Haier added wording to their instructions
saying they don’t work if outside temperatures fall below 60°F. In our
experience, this isn’t true – these are great through even Canadian
winters and nothing changed in 2010, just the wording in their
instructions. Avoid models beginning with HWE.
Frigidaire: We are having great experiences with the
2015 and 2016 Frigidaire models, except the 12K BTU models. Be sure to
select one with automatic restart. Avoid pre-2015 models and the 12K BTU
General Electric (GE): GE is widely available, but
its compatibility with the CoolBot is very model specific. Some models
have a second sensor that requires extra steps during installation
(which we walk through on the Installation page). Since 2013, GE models
restart automatically after a power failure and generally work fine in
the winter. We are still gathering information on the 2016 models.
GE Model Notes – Compatible models:
- 24K BTU: AEE24DT, AEM25DP, AEW24DS, AEH24DT, and AEM24DQ.
- 18K BTU: AEE18DT, and AEW18DS.
- 12K BTU units: AEL12AS, AEM12AS, and AEZ12AS
GE Models to avoid:
- Pre-2010 models
- AEZ12AT, AEM10AT, AEL24DS, AHH10AS, AEL24DQ, AEH12AT, all AHL##AS,
and all AEM##DT models – their sensors are difficult to work with during
- AEW12AS and AEL12AR – they are too small to cool the air down
Brands with limited window unit experience, but no problems:
We sell CoolBots all over the world, and sometimes our customers have
trouble finding one of our top supported brands. While we have less
experience with these other brands, so far we have not had any issues
with the following brands:
- Samsung (hundreds of users with good feedback; don’t know if they have auto-restart in case of electrical failure)
- Comfort Aire
- Arctic King
Because of our limited experience with
these brands, we do not have data on how they perform during the winter.
If that is an important feature to you, please use one of our
recommended brands (GE, Danby, LG or Haier), or contact us and we can
discuss your setup in more detail.
