How Air Conditioning Re-Gas Works

If your car’s air conditioning system is not cooling the car down as it should or is blowing out
warmer air, it’s not running efficiently and it may be in need of a re-gas.

The amount of gas needed to recharge your vehicle’s air conditioning depends on the make and
model. Gas is measured by weight so a smaller car will require less. On average a small model will
need around 1/2 kilo of gas to fill up the air conditioning system. A large, luxury model will require
around 1 1/2 kilos.

Most vehicles lose around 10% of refrigerant gas per year. Car air conditioning specialists
recommend that you have your air con system checked annually and that a full service should be
done every two years. Keeping your vehicle sufficiently re-gassed is fundamental for the overall
efficiency of your air conditioning system. Here are some other points to consider.

Safety Issues

Today most vehicles use R134a or the newer R1234yf refrigerant gas. They are non explosive, more
environmentally friendly and are not toxic if leaked into the car interior.
However, it is not recommended that you attempt to ‘top up’ your vehicle’s air conditioning system
yourself. Cheaper re-gas kits are available to buy, but don’t think that you will be saving money.

They can be dangerous if you’re not sure what you’re doing. A re-gas should always be carried out
by a qualified specialist.

It’s not just a case of ‘topping up’. If your air conditioning system contains moisture or
contaminants, it will take a qualified professional between 20 and 30 minutes to remove these
before the re-gas can begin. It will then take up to an hour for a properly controlled re-gas to be

Gases Used

Before 2001, vehicles used an R12 refrigerant gas known as Freon in their air conditioning systems.
Since then, the EU has banned this gas because of its ozone layer destroying properties. Freon was
replaced with the more environmentally friendly R134a gas. However, even this is being phased out
and replaced by the safer R1234yf gas.
