Why doesn't my air conditioning blow cold?

Usually drop in gas pressure in the system will result in a system failing to operate. With our Aircon service we ensure that your air conditioning system is working efficiently by testing the gas pressure to see if it has dropped. The process works as follows:

  • Our fully trained technicians will take a temperature reading from your air conditioning system.
  • Once all the old refrigerant gas, and any oil has been removed, the whole system is pressure tested and cleaned to ensure any moisture is removed.
  • Once the system has been thoroughly cleansed our technicians will inject new oil, refrigerant gas and a UV dye into the system.

The UV dye is used to assist in the locating of any tiny leaks that may not be apparent after pressure testing. If we locate any leakage within the system we will offer a no obligation quote to ensure that your air conditioning system is working to its full potential.

Air con regassing

There could be other reasons why your air-con isn't blowing cold anymore, but our specialists will be able to advise if the issue is the result of anything other than the need for regassing.

Can I regas my air-con system myself?

You can buy air-con regas kits if you’d like to attempt the job yourself, but we wouldn’t advise it. They’re almost as expensive as paying a specialist to do the job and iIt is impossible to test for possible leaks without correct equipment. If you are not certain that the system is completely sealed the new gas will just leak away.

Our Specialists will also have a better idea of how to check for leaks and other problems with the air-con system, and there are safety factors to be considered, too. If the refrigerant gas comes into contact with your skin or eyes, it could cause painful freeze burns.

How do you know when your air-con needs regassing?

The first sign that your air-con needs regassing is that the air being blown from the vents is not as cool as it used to be, or it doesn’t feel any different when the AC is switched off.

If you can’t remember the last time the system was regassed, it’s probably worth doing. Alternatively, our Specialists are happy to perform a free check.

How much does an air-con regas cost?

Getting your air con regassed costs somewhere around £50 to £200 depending on your system.

How often should you get your air-con regassed? When should it be serviced?

Most manufacturers recommend you service your car’s air-con every two years or so, but many people wait until it’s not blowing cold air.

This is unlikely to cause any harm, but bear in mind that poorly-functioning air-con will make it more difficult to demist windows in winter and could work the engine harder, thus using more fuel, so it’s not worth putting off a system check.

Is a regas part of a service?

Air-con regas

While servicing you car is important for keeping it in reliable and roadworthy condition, services do not tend include the air-con system.

When your car’s air-con is given a service, the technician will check the system’s lubricant level and replace the old refrigerant gas with new gas up to the required level.

They will also perform a vacuum and pressure test to check for any cracks or leaks that could prevent your air-con working in the future.

What happens if I don’t regas my air-con system?

If you don’t regas the air-con system, it will gradually become less efficient, making the car uncomfortable in hot weather, and take longer to demist the windows in winter.

Not regassing your air-con system may also be bad for it in the long run, too, with pipes likely to crack and parts likely to seize up if it isn’t used.

What else do I need to consider about my car’s air-con, and how do I maintain it?

As well as getting the system re-gassed, the best way to keep your air-con in top form is to use it all year round.

Change the cabin filter regularly, and consider an anti-bacterial clean if you notice musty smells coming from the vents.
