The weather is finally heating up, and we are crossing our fingers that it will last. It might not, but with the ever unpredictable British weather, it's always a good idea to make sure your air conditioning is properly maintained for when you need it. Not only that, air-conditioning can be just as indispensable during the winter months, helping keep your windows clear of condensation whatever the weather, as well as helping filter out pollen, pollutants and airborne bacteria.

Keeping it Running

Make sure you try and run the air-conditioning once a week for about 10 minutes. This is best done at the highest and coolest setting and will help maintain gas pressure to keep it working properly.

Recharge Regularly

Air-conditioning systems work in the same way as a fridge - the air is cooled with a refrigerant gas and that circulates through your car. As with other liquids in your car, such as the oil, the air-conditioning coolant should also be refreshed (known as recharging or a re-gas). The coolant should be drained, refilled, and key components should be lubricated to keep them working efficiently. Most manufacturers recommend a recharge every two years, but best to check your vehicle's handbook.

Do It Yourself?

You can in fact re-gas your air-conditioning yourself, and with various DIY products available at a reasonable price, this can be a tempting option. However, the DIY route does not come recommended as it doesn't allow you to identify potential leaks in the system. Unless you know exactly what you're doing, you could be refuelling a leaky system, meaning it will lose its effectiveness in a matter of hours.

Not only that, if you charge a leaky air-conditioning system, you are effectively discharging refrigerant directly into the atmosphere. This is an illegal act of pollution under the Environmental Protection Act 1990 and could land you with a hefty fine!

Or use the Professionals?

With air-conditioning fitted in most cars these days, the re-gas market has become increasingly competitive. Making sure you use a qualified professional, they will be able to properly re-gas your system with the precise amount of gas needed for your system along with the right amount lubricant to preserve the moving compressor parts and keeping seals moist and effective. On top of this, they are also able to identify any leaks in the system. So if necessary, you can have it repaired before re-gassing.

When it comes to re-gassing or recharging your car's air-conditioning, it's one that's probably best left to the professionals. The peace of mind from knowing the work has been carried out properly, without potential harm to the environment, far outweighs any minor cost saving in attempting the job yourself.
