Central AC won't come on. We can turn it on by flipping the circuit breaker. It will run for a short time and kick off.

We have an Energy Star AC and a programmable thermostat, but every three years we have to have a service call for our unit.

It sounds as though you have a pinhole leak.

Freon leaks can be found with a soapy water solution, but the leak may not be in an accessible location. A good AC tech can use a "sniffer" to check for leaks, but since this is common and repair can be difficult and expensive, most techs just add a little freon and call it good.
