A sentence described as 4 and 4 most commonly means one of two things, and which one applies makes a significant difference in how long your son will actually be incarcerated.

The first possibility is a split sentence. This means the judge sentenced him to 8 years total but ordered that 4 years be served in custody and the remaining 4 years be served on probation or supervised release in the community. Under this structure, your son would serve the custodial portion, potentially less with good time credits, and then be released under supervision for the second 4-year period. He would be home after the first portion is served, but under supervision with conditions he must comply with.

The second possibility is two consecutive sentences of 4 years each that run back-to-back, totaling 8 years. Under this structure, he would serve both terms sequentially, one after the other, before full release. Good time credits would apply to each term separately.

A third less common possibility is two concurrent sentences of 4 years each running simultaneously, which would effectively mean a total of 4 years rather than 8 since both sentences are served at the same time.

The exact meaning depends on the jurisdiction, the specific charges, and the language of the sentencing order. The clearest way to find out which structure applies is to get a copy of the judgment and commitment document, which spells out the sentence terms precisely. Your son's attorney should have this document and can explain exactly what was ordered and what the actual timeline looks like.
