Your air conditioning system can lose up to 15% of it’s coolant every year, so a 3 year old car may have lost almost half it’s coolant seriously impacting on the performance of the system and damaging the components involved.

What are the benefits of a healthy air conditioning system?

  • Efficient cool air in summer
  • Warm dehumidified air in winter easily demists steamed up windows
  • Filters pollutants / airborne particles inc pollen helping allergy sufferers
  • Pleasant and odour and bacteria-free air atmosphere at all times

You should regularly have the air conditioning systems serviced to reduce wear and tear on the components and help avoid potentially big repair bills.

Why recharge your car air conditioning?

Keeping cool… There are many reasons to get your air conditioning recharged besides the most obvious one being to keep you and your passengers cool on journeys in hot weather (though we might add that leaving a box of lollies in a non-air conditioned car for too long can be very upsetting for kids and grown-ups alike). If you like getting the most out of your tank of fuel then you might be interested to know that recharging your air con increases fuel efficiency. This is because when your air con refrigerant is low, the air con system struggles to cool the air and so works harder to try and produce cold air. This extra work uses more fuel.

Less expensive repairs… Similarly, it pays to recharge regularly if you don’t want to have to pay out for expensive air con parts and repairs later on. The refrigerant used in your air con system is extremely cold and has the added benefit of cooling down the air con compressor. Without refrigerant, or if it were to run too low, the compressor would get dangerously hot and fail.

A benefit for all year round not just summer… Air conditioning even has its uses on cold winter days. If you are struggling to demist your windscreen, pop the air con on to produce dry warm air to rapidly clear your view. Turning your air con on during the colder months of the year also ensures the system doesn’t seize up and will continue to work effectively when the temperature starts to warm up.

Why does air conditioning stop working?

The refrigerant, or gas, found in your air conditioning unit is critical to the air con system working properly. It is this refrigerant that flows around the system and provides the cold air in your cabin. However, as a result of this process which involves continually shifting states from gas, to liquid and back to gas again, some of this air con gas permeates through the system each year. Less gas means less cool air so refilling every few years will keep your air con working in tip top condition.

Of course there are other reasons why air con stops working but low refrigerant is the most common and, thankfully, the easiest to fix. If after a regas your air con is still blowing warm, it probably means there is a crack somewhere in the pipes of the air con system and the refrigerant is escaping.

Is air con part of my MOT or Service?

No, your annual MOT ensures the vehicle is safe to drive as per strict DVSA guidelines. Since air conditioning is considered a ‘nice-to-have’ feature and is not critical to the safe running of the vehicle, your MOT tester will not check to see if your air con is working.

Similarly, air con is not included in the standard service schedule set out by your vehicle manufacturer. Regular servicing will help keep your car running for longer in a safe and reliable condition and includes some replacement parts like the oil and air filters. But those drivers expecting their air con to be recharged as part of their service will be disappointed. Many manufacturers provide a separate air con service schedule which will recommend a re-gas, on average, every 2 years.

How long does an air conditioning recharge take?

The process take about 45 minutes to completely remove the old gas and refill with fresh refrigerant.
