I have an air handler in the garage that started leaking a week or so ago. I have an ouside air conditioner (central?) and it also has stopped... when I move the thermostat I hear it click on but no air...

Anybody?

Check your breakers and fuses near the a/c unit. Also what was it leaking ? Water or freon?

Do you happen to have a condensate pump that gets rid of the water from the evaporator coil?

You could have a float switch that shuts the unit down when the condensate pan fills up. Find the drain, and clean it.
