The new HFO-1234yf gas and cleaning for your Air Conditioning at Ace

For many years we have provided air con re-gassing as a service. Our customers have enjoyed freezing cold air conditioning down to as low as -11 degrees, and for many years the R134a was the standard.

But since 2017, all new vehicles have been required by law to switch to the new HFO-1234yf gas. This gas produces 98% less climate-damaging pollutants than its predecessor.

This has left many of our customers out in the [hot]. So this month we've finally invested in a brand new machine.

When you book, you'll need to check which gas your vehicle takes. If your vehicle is newer than 2017 then it will definitely require the new HFO-1234yf gas, but it can be in some as early as 2013. Lift the bonnet and look for anywhere that says either HFO-1234yf (new gas) or R1234a (old gas). If not, call us before you book and we can check our end and let you know!


Your vehicle's air-conditioning should be serviced around every 18 months.

Your car air conditioning will lose around 10% of its coolant every year reducing its efficiency.

Your air conditioning can also house deadly diseases which will be spread through the vehicle:

A 2018 study by Kwik Fit and researchers at London Metropolitan University revealed the potentially dangerous bacteria living in the air conditioning systems of British cars.

The bacteria found is associated with meningitis, urinary tract infections and septic arthritis were among the many types found.

In the study, swabs of 15 air conditioning filters taken from different cars across the UK and subjected to the laboratory analysis.

All filters tested had microorganism detected, with the most common of which being Bacillus Licheniformis.

Bacillus subtilis and Bacillus were the second most common microorganisms found.

Bacillus subtilis are normally found in the gastrointestinal tract of humans and some mammals and Bacillus has links with a wide range of infections including meningitis, abscesses and septicaemia.

Kwik Fit advises that systems which have not been cleaned regularly may not only cause bad smells, they may be harbouring something more serious.

Dr Paul Matewele, senior lecturer, London Metropolitan University commented: “We discovered a variety of microorganisms in the air conditioning filters.

“Some of the bacteria found has links to animals, the gastrointestinal tract of humans and some very nasty infections which could cause a lot of harm to individuals, especially those with a compromised immune system.

“The research shows some harmful bacteria found in the air conditioning systems which is being circulated around driver’s vehicles.

“Many of us leave our air conditioning off throughout the winter months and turn back on when the weather warms up without considering the cleanliness of the air conditioning filters.

“Over time bacteria, mould and fungi can build up on a vehicles’ air conditioning unit which can either be odourless or create a bad odour when switched on.

“If motorists leave the bacteria in place it can cause sickness and respiratory problems as it gets blown into the cabin of the vehicle and inhaled by passengers.

“We recommend that all motorists have their air conditioning debugged at least once every two years to decontaminate the system and kill the bacteria within.”

With this in mind, here at Ace we've also added an AIR CON CLEAN to our line up.

Here's a list of all the different bacteria that can end up growing inside your air con:

Bacillus Licheniformis - Bird feathers, soil and infections associated with central venous catheters Bacillus Subtilis - Gastrointestinal tract of humans and some mammals, generally non-pathogenic but has caused septicaemia in a patient with leukaemia Bacillus - Common environmental bacteria which has links with a wide range of infections including meningitis, abscesses and septicaemia Pasteurella Pneumotropica - Found in animals but may infect humans because of an animal bite or scratch Bacillus Pumilus - Generally non-pathogenic but has caused skin infections Brevundimonas Vesicularis - A major problem for immune-compromised individuals. Has caused bacteraemia, cutaneous infections, meningitis, peritonitis and septic arthritis Enterococcus Faecium - Gastrointestinal tract of humans and animals, but can also be pathogenic and linked with diseases such as meningitis, endocarditis and VRE Aerococcus Viridans - Urinary tract infections, bacteremia, septic arthritis, and infectious endocarditis Empedobacter brevis - Rarely causes disease but has been implicated in immune-compromised individuals Elizabethkingia meningoseptica - Common environmental bacteria usually present on fish and frogs. It is an opportunistic pathogen that can cause meningitis in immunocompromised people
