Had the timing belt, tensioner, water pump and plugs replaced and radiator coolant, hoses and thermostat replaced on my 2.5L DOHC Subaru Legacy and after that the car now idles rough when the AC is on. Is this a problem with the repairs or something new?

Seems to run OK. Wouldn't there be noticeable running problems with the timing belt off?
