FAQ Aircon Regas
Introduction
Air conditioning is now virtually standard in all new cars sold in the UK. Not only is it essential for driver comfort but it also plays an important part in demisting your vehicle in the winter. Aircon regas, also known as an air con recharge, is a vital part of aircon maintenance. It replenishes the refrigerant gas in your car's cooling system that gradually depletes over time. At Protyre, we take aircon seriously, so we've compiled this comprehensive list of frequently asked questions about aircon regas to help you understand what it is, why it's important, and what to expect when you bring your vehicle to a garage.
Aircon regas is the process of removing old refrigerant from your vehicle's air conditioning system and refilling it with correct amount of refrigerant, whilst also ensuring that the system is pressurised to the correct level to ensure optimum working performance. While carrying out the regas, a mechanic or engineer will also check for leaks and make sure the system's pressure is correct.
Air conditioning works by cycling a refrigerant gas through a closed loop that absorbs heat and disperses it outside the vehicle. Even in the best aircon systems, the refrigerant escapes over time and the system's ability to keep the interior cool diminishes. A regas restores the gas levels and the system's performance.
Most manufacturers and experts recommend that, in order to keep your system working efficiently, you should have it routinely regassed roughly every 1䃀years. If you notice a drop-off in performance, you should get it checked sooner.
In a typical garage it should take about 45minutes. If extra checks need to be carried out, it will, of course, take longer.
It depends on factors like the type of vehicle, the refrigerant used and whether any other services or checks are carried out, but the cost usually ranges from £40 to £150.
If you notice that your vehicle isn't being cooled properly, you notice a musty smell, the windows are slow to demist or you hear unusual noises when the system is running, you should get the system checked.
DIY kits are not recommended. They can't remove old gas or check for leaks properly and may even damage the system.
Not always. If there's a leak or a faulty component, like the compressor, you may need additional car air conditioning repairs.
Aircon regas is usually not included in standard vehicle servicing so you may need to book it separately.
Bacteria and mould in the vents can cause odours. A regas restores the cooling function, but your vehicle might need a separate clean or filter change to eliminate odours.
If your refrigerant is low, your system may have to work harder, which can slightly increase your fuel consumption.
Yes, but your vehicle won't cool or demist properly. Over time, it might also put strain on the system.
No, aircon performance is not checked during an MOT since it doesn't relate to safety or emissions and must be monitored separately.
If the performance of your aircon declines more frequently than expected you may have a leak. Simply regassing won't fix this problem.
Yes, if you run the system for short periods once a week, even in winter, you'll help the oil to circulate and maintain seals, which can prevent leaks.
Yes. A properly functioning aircon system helps remove humidity and clear condensation from the windscreen and windows.
Book it with a reputable garage or service centre that specialises in air con maintenance, such as garages, where you can get your aircon regassed and checked for leaks and other problems.
