Contrary to popular belief, auto air con does need servicing. Not always a recharge of the system, but at least a pressure test.
Sound like yours has lost its charge. A simple test from a decent air con specialist will tell you if thats the case. They have preset pressure readings to see if the system has lost charge or not.
Also, when the system is filled/refilled, a lubricant is added to the charge gas. This helps to lubricate the joints in the system, the seals.
If air con is not used enough, these seals can/do dry out creating a leak in the system. It is best practice to use the air con at least once a week to keep these seals lubricated.
Maybe yours has just dried out and needs a refresh? Anywhere between £35 and £65 for a recharge depending on where you go.
DO you get a "dry" almost metallic rattle when the air con is switched on and the fan turned up? This can be a sign of an empty system.
