A fluctuating noise is a possible motor bearing or fuel pump. Either would be very rare with a burner less than a year old. One thing I would check is the fuel filter to be sure it is clean.

If the boiler is already zoned, I would replace the boiler & add A/C (1 system up & 1 down). I have always prefered to heat with a heating system & cool with a cooling system.
