If your car's air conditioning isn't blowing as cold as it used to, it probably needs an air conditioning regas — the process of removing the old refrigerant gas from the system and recharging it with new refrigerant to restore cooling performance, usually every two years as gas is gradually lost over time. For car and light van owners in Tunbridge Wells and the surrounding areas, Freeway Fast Fit provides reliable, honest and affordable regas and air conditioning maintenance to keep the system working efficiently, comfortably and without putting extra strain on fuel use.
Unlike places that simply top up the gas, we always inspect for leaks or other faults first, then properly remove all of the old gas before recharging the system with the correct new refrigerant. Below, you'll find the signs that a regas is due, what happens during the service, pricing and refrigerant types, odour treatment, why it's worth using your air con all year round, and why drivers have trusted us with their cars since 1973.
Car air conditioning systems naturally lose refrigerant gas over time. Approximately 10% of the gas is lost each year, even when there's nothing wrong with the system. As the level drops, the air con has to work harder to cool the air and becomes less effective.
That's why most manufacturers recommend an air conditioning regas every two years, helping make sure your system is always working to its full potential.
It might be time to replenish your air conditioning gas if you notice the following:
The air isn't as cold as it used to be
It takes longer to cool the car down
Your windscreen takes longer to de mist
The air con only blows warm air
There's a musty smell from the vents or other unpleasant odours
You haven't had the system regassed in the last two years
Our air conditioning service includes:
Initial inspection. We check the system for leaks and other faults before any work is carried out.
Old gas removed. All of the old refrigerant gas is properly recovered from the system.
System recharged. The system is then re-gassed with the correct air con gas required for your vehicle.
Performance check. Vent temperature and operation are tested after the regas.
We carry out a vacuum test before refill, and environmental law requires specialist equipment when handling refrigerants.
If we find a fault, such as a leak, we'll explain what's wrong and what it will cost to fix before going any further; if no refrigerant remains, we can re gas the system only after a pressure test.
Our air con regas cost depends on the refrigerant your car needs and the work required.
Cars use one of two types of refrigerant gas. In most vehicles manufactured before 2017, that will be R134A gas, while vehicles manufactured after January 2017 generally require R1234YF gas, which is more environmentally friendly than R134A because of its lower global warming impact.
Our air conditioning services starts from £100, depending on the type of vehicle and the work required. If you're not sure which your car uses, give us a call with your vehicle registration and we'll check for you.
Bacteria and dirt can build up in your air conditioning system, especially if it hasn't been used for a while, causing a musty smell from the vents. As part of our air conditioning services and car air conditioning services, we offer an additional odour treatment alongside our standard air conditioning regas, designed to circulate cleaner through the air intakes, target harmful bacteria, and leave your car smelling fresh.
Change the pollen filter regularly, keep the cabin filter regularly checked, and consider an anti bacterial clean to improve air quality inside the car and reduce unpleasant smells.
If you notice musty smells coming from the vents, or think a smell may be caused by a leak, bring your car in as soon as possible.
Air conditioning isn't just for summer. In winter, it helps create drier, warmer air and clears misted windows faster by supporting your air con system, which helps you see clearly. Running your air con regularly also helps keep the system in good working order.
A well-maintained system can also save you money, as a system low on refrigerant works harder and uses more fuel; maintaining cooling efficiency can also support fuel efficiency in hot weather, when weak performance can make the car uncomfortable.
No. Your air conditioning isn't checked during an MOT, as it isn't a safety item. It also may not be included in a standard car service, which is why booking a separate air con service or air conditioning recharge matters, and why we recommend a regas every two years.
We do it properly. Leak checks first, old gas removed, then a full recharge.

Most vehicle manufacturers recommend an air conditioning regas about every two years, as systems naturally lose around 10% of their gas each year.
An aircon recharge typically takes about one hour, depending on the vehicle and any checks needed.
The most common cause is low refrigerant, which can stop the system blowing cold air properly, and air con regassing can restore it. If the vehicle's air conditioning still blows warm air after recharge, there may be a leak or a fault with a component such as the compressor, which we can investigate.
We'll explain what we've found and give you a price for the repair. If no refrigerant remains, the system may need a pressure test before it is re gas. There's no point recharging a system that will quickly lose its gas again, so we'll always be upfront with you.
Most cars built in recent years use R1234yf, while older cars generally use R134a, and a small number of EVs use R744 refrigerant. You can check the label under the bonnet or provide your registration so we can confirm the gas required.
