What is the lifetime of an AC unit?

15 to 20 years

Should I replace my 20 year old air conditioner?

The average lifespan of an HVAC system is 15 to 20 years, but as these systems age, they tend to get less efficient. If your HVAC is over 10 years old, consider replacing it with a more energy-efficient unit, such as one that has earned the ENERGY STAR label.

Can I replace a 3 ton AC with a 5 ton AC unit?

The short answer is, you can’t. A good tech might be able to get it to work with like a TXV, but you are going to be bottle-necked at the 3-ton. There is no way you will get 5-ton capacity after that.
