Is It Worth Getting an AC Regas Before Summer?

If your car's air conditioning is not cooling as effectively as it used to, the most likely cause is a gradual loss of refrigerant. Car air conditioning systems are not sealed indefinitely — they lose around 10–15% of their refrigerant each year through normal use and micro-leaks.

Signs Your AC Needs a Regas: The air is blowing but not very cold, even on the maximum setting. It takes a long time for the cabin to cool down. The system is making unusual noises when the AC is switched on. The AC light is flashing or showing a fault.

What a Regas Involves: We evacuate the remaining refrigerant from the system. We check for leaks using UV dye and pressure testing. We recharge the system with the correct refrigerant (R134a or the newer R1234yf, depending on your car). We test the system performance and verify the temperature at the vents. The whole process takes around 45 minutes.

Is It Worth It Before Summer? Yes. Having your AC recharged in spring — before the hot weather arrives — means your car is ready when you need it. It is also typically more available and quicker to book than in the height of summer.
