The new gas is R1234a "Solstice" gas and is about twice the price of the old R134a so they're trying to "price condition" people by jacking up the price of the R134a but what they can't condition people for is the fact the Solstice gas loses its effectiveness and tends to leak out after 2 years. 
In other words, the sooner you do it, the cheaper it's going to be. |
I'm going to get an oil and filter change and gearbox drain and refill at a garage I use in Birmingham on Thursday, so while there I'll get them to evacuate the AC and see how much its lost!
I'll also ask them how much they would charge to re-gas one changed pipes, and O rings to a larger size.
It definately needs a leak sealer, a good idea!
Probably wont do it for a month as may be working on a bungalow for an old client.
Not good news on the gas! Especially if prone to leak!
