Air conditioner refrigerant gas legislation

If you need a new air conditioning installation, it will either contain R32 or R410A. R22 is illegal to use in new systems in the UK – this is because it contributes to ozone depletion. However, there are still lots of older air conditioning systems that still use it, as the ban didn’t come into place until 2010.

R32 is the newest and most popular air conditioner refrigerant gas. This is because of its relatively high efficiency and low GWP (Global Warming Potential). R410A is also popular, but its higher GWP means that its more harmful to the environment. Different gases suit different system types, so when we design your air conditioning installation, we’ll make sure you get the best one for you.
