To serve you better, O'Brien's Auto Repair is now open from 7 AM to 6 PM.
The weather is officially drifting into the hot zone, which means windows are up and air conditioning is in full effect. This is fine if your a/c is in top shape, but if it's out of commission or running at half cool, you're starting to sweat the situation.
The problem with air conditioning systems is that they can have a very slow leak that is pretty much undetectable. This doesn't mean you shouldn't try to find the leak. Be sure that your mechanic did a dye test under full pressure, while the car was running with the a/c on. This can uncover some pretty small leaks in the system.
