How much does it cost to fix car air conditioning?

Re-gas: £50–£90. Leak repair + re-gas: £180–£450. Compressor replacement: £450–£1,200 fitted.

Here's a quick, honest answer from a working UK mechanic — what causes it, what it costs to fix, and what to do next.

Will Aircon Boost from a can work? — Avoid them — many contain sealants that contaminate and damage compressors.

Should I run the air con in winter? — Yes, weekly for 5+ minutes. It keeps the compressor seals lubricated and stops leaks developing.
