AC Refrigerant Refill up to 700 g

from €70

AC refrigerant refill replenishes the refrigerant that naturally leaks out of the system over time, at a rate of around 10% per year. We evacuate the old refrigerant, check the system for leaks, refill it with fresh refrigerant up to 700 g, and add compressor oil. A timely refill protects the compressor from running dry and prevents it from failing, since repairing or replacing a compressor costs far more than a refill.

When to get in touch

If you notice any of these, it’s better not to wait:

  • The air conditioning is cooling the cabin worse than before
  • Cold air takes a while to appear after turning the AC on
  • More than 2 years have passed since the last refill
  • The AC compressor makes an unusual noise when it kicks in
  • Air from the vents is only cold for a short time
  • The AC system hasn't been checked in a long time
  • Summer is approaching and you want to make sure the AC is working well
  • The air conditioning isn't cooling the air at all
  • The air conditioning isn't cooling the air at all

Why the AC needs regular refilling

A car's AC system isn't completely sealed — refrigerant gradually escapes through seals, hoses and fittings, and the system loses about 10% of its volume per year. This is a natural process rather than a fault, but it does need to be topped up regularly.

If the refrigerant level isn't maintained, the compressor starts running with insufficient lubrication and cooling — a condition known as running dry. This quickly wears the compressor down and leads to failure, and replacing it costs significantly more than a routine refill.


How the AC refill is carried out

Refilling the AC isn't just about adding refrigerant to the system — it's a comprehensive procedure. We carry out the full cycle:

  • Evacuating the old refrigerant from the system
  • Checking the system for leaks and tightness
  • Vacuuming the system before refilling
  • Refilling it with the required amount of fresh refrigerant, up to 700 g
  • Adding compressor oil to lubricate the compressor
  • Checking pressure and outlet temperature after the refill

This approach doesn't just top up the refrigerant — it also confirms the system is sealed and ready for continued use.


Leak inspection

Before refilling, we always check the AC system for leaks. If refrigerant is being lost faster than the natural 10% per year, it can point to damage in the hoses, seals, or the AC radiator.

Catching a leak early lets us fix the actual cause of the problem, rather than just periodically topping up refrigerant in a faulty system.


Why timely refilling matters

Running the compressor without enough refrigerant and oil causes internal components to overheat and wear out. Unlike a refill, which is a routine and relatively inexpensive procedure, repairing or replacing the compressor requires significantly more time and money.

Refilling the AC every 2 years is a simple way to avoid costly repairs and keep the cabin cooling system working properly for the long term.

Frequently asked questions

The cost depends on the refill volume and whether extra work is needed, for example if a leak is found. You can confirm the exact price when booking.

We recommend refilling the AC every 2 years, since refrigerant naturally leaks out of the system at a rate of around 10% per year.

A lack of refrigerant causes the compressor to run dry, leading to overheating, wear, and eventual failure. Replacing the compressor costs significantly more than a refill.

Yes, we always check the system's tightness before refilling, to catch any leaks and avoid refilling a faulty system.

We evacuate the old refrigerant, check the system for leaks, refill it with fresh refrigerant up to 700 g, and add compressor oil.

The main cause is a drop in the system's refrigerant level due to natural loss or a leak. Diagnostics and a refill help restore cooling performance.
