Just cause your system has a 3 ton name plate, doesn't guarantee
you're getting three tons of cooling. I'm remembering a call I
had last year. the fellow had a 3.5 ton AC, and it wasn't cooling
the house. He was thinking maybe needed 5 tons. I asked his
permission to service the unit, and when I finished, it was
cooling just fine.
You may replace the system if you like, but it's possible that a
good servicing would get you by for several more years.
