Can I Keep a Chest Freezer in my Garage or Outbuilding?
THE SHORT ANSWER
For a freezer to function correctly in an unheated area such as a garge or outbuilding depends on a couple of things:
- The climate class rating for that freezer
- Whether it has any freezer-guard technology that allow it to keep working in low ambient air temperatures
A question we are often asked is:
“ Can I use a chest freezer in a garage? ”
This also of course applies to other unheated outside areas like a shed or outbuilding.
Although a freezer can generate internal temperatures of -18 degrees Celsius, the mechanical and electronic components that make this happen don't work too efficiently when the ambient air temperature in the room is too low.

Climate Class Confusion
Most manufacturers usually only design their refrigeration appliances to operate within a temperature range defined by an official "Climate Class".
The lowest climate class temperature is 10 degrees Celsius - not helpful if you want to keep the freezer in the garage during the winter.
Happily, some manufacturers have come to the rescue and moved on from these strict climate classes!
There are several climate classes that cover different temperature ranges - with Class SN having the lowest operating temperature of 10 Degrees Celsius. This is fine most of the year but of course temperatures can dip below this in winter.
Of course, some people claim to have used a freezer in the garage for years with no problems, and some appliance repair specialists say it's a definite no-no and that manufacturers are unrealistic when they say that their freezers are ok to be kept in an unheated space.
We all know that many people do keep their fridges and freezers in garages and experience no problems at all.
In some cases this could just be down to luck or maybe their outside space doesn't actually dip too far below the recommended level.
You do have to remember though that if your freezer does develops a fault, the warranty may not be valid if the product was kept in an area where there temperature was outside the range it was designed for.
Let's Go Outside
More and more manufacturers know that many people have limited indoor space and have specifically made their chest freezers suitable for the garage and other types of outbuilding.
This is often achieved with a 'concealed condenser' which is specially located inside the freezer to be better protected from the elements.
Ice King, Russell Hobbs and Logik (a Currys own brand) confirm that at least some of their products can be used in unheated garages or sheds
Beko go a stage further and say that some of their products can operate down to -15C with their FreezerGuard technology.
They Say It's OK But ...
You should also be wary of some retailers that claim certain freezers are suitable for outbuilding use but where the climate class rating states 10 or even 16 Celsius is the minimum.
Always check that the specifications states a minimum temperature that is 0 degrees Celsius or below if you wish to safely keep your freezer outside.
Whatever the case, it is important to ensure that the location for the freezer does meet some basic requirements:
- It should be dry and free from damp and extreme high and low temperatures
- The surface it stands on should be level (some units may have adjustable feet to help here)
- It is vitally important to allow enough room around the unit (especially the back) for good airflow
- Oh and don't forget about the summer high temperatures too - your poor freezer will already be working hard so ensure that the location won't get too hot
So, Can I Keep a Chest Freezer In My Garage?
You need to be aware of the minimum temperatures that will occur within the location of your freezer. Also, pay close attention to the climate class and whether the manufacturer expressly states that the freezer can be used in colder conditions.
If you are concerned that the ambient temperature in your desired location will fall below freezing, it is worth seeking out a product from a manufacturer that specifically approves that their product is suitable for such environments.
Luckily more and more manufacturers seem to be realising that people today really need their freezer to work reliably outside.
TIP: Use a minimum-maximum thermometer to check the lowest temperature that your garage falls to overnight, though this will only be useful to do during the winter months.
Fridge Freezers are Different
On a side note, while a standalone chest freezer is designed to continually maintain a very low temperature, you should be aware that a combined fridge/freezer only has one refrigeration unit for both compartments.
Therefore if the room temperature is too cold then you may find the freezer compartment starts to defrost because the fridge compartment hasn't got "warm" enough to cause the compressor to run.
Our advice: definitely don't keep a combined fridge-freezer in a place where temperatures are likely to be close to or below zero degrees Celsius.
