For Silver Maples, the safest time is very early spring, just prior to bud
break (keep an eye peeled for flowering, then go for it just as the buds
swell).

I have a 15 year old Silver Maple that needs to have its lower
branches cut to increase the headroom underneath. When is the best
time of year to do this?

many thanks,

Bad timing for maples in general they bleed all down the trunk when
spring pruned.
If you must cut them for head room now leave stubs a foot or two long
and then remove them just outside the branch collar in Summer.
That way you don't mar the trunk with sap and when you make the
cleanup cuts in summer the branch collar can make the bark to heal the
wounds.
