WhoCanFixMyCar explains what an aircon regas is and why it's beneficial to have one
Each year there is at least a 300% increase in demand for aircon regas work from drivers during the summer months as temperatures soar.
Car interiors are excellent at trapping and storing heat, making them uncomfortable places to be if you don't have a functioning AC system. Fortunately, having your aircon regassed is quick and affordable.
What is an aircon regas?
An air conditioning system works by using refrigerant gas to push air through several components in the aircon system and then into your car.
Surprisingly, over 10% of aircon gas escapes through the system each year. This means that the power of the system drops significantly over time. However, your air conditioning will not be checked during an MOT or service, which is why it’s important that you make an effort to have it checked specifically.
So what is involved in an aircon regas?
These are the steps involved:
The mechanic will firstly carry out a leaks check on the air con system before they start the job. As soon as the leak check is complete, the technician will be able to recharge the aircon system.
The mechanic carrying out the work will first remove old refrigerant from your car as well as the lubricant and replace it with new gas and lubricants.
During this process an entire system clean out will usually be performed to remove any bacteria build up.
The whole process should take around 45 minutes as there are no new parts required. The air conditioning in your car should be noticeably improved after a regas if you haven’t had one for over two years.
If you want to ensure your air conditioning stays in tip top condition, make sure to use it regularly as the compressor will stay lubricated with regular use.
What aircon gas is in my car?
In 2017 a new regulation was brought in requiring a certain type of aircon gas to be used in all new models. This gas, or refrigerant, is known as HFO-1234yf. Compared to its predecessor, R134a, it produces 98% fewer harmful pollutants.
Aircon leak repair
While a small amount of gas will naturally escape from your aircon each year, there might be a leak causing the gas to escape faster than it should. If this is the case, the mechanic carrying out your aircon regas will identify the problem and carry out necessary repairs, usually for a small additional fee.
