Should I put in new windows?

[Daniel Paloscio]

I just bought my first duplex recently. A 3/1 2/1 block, built in '73. I'm going to live in the 3/1 for the next year or 2. Would it be a wise investment to buy new windows for the property? It has the old roll out windows but none are broken or malfunctioning. In the year I stay there I probably won't save the cost of the windows on the electric bill.
