The size and capacity of your home comfort system are crucial factors in whether it can do its job properly. That's why it's wise to get a "load calculation" -- a measurement of the heating and cooling output your home needs.
A too-small system will not be able to keep up with demand, but it will work very hard trying -- leading to unnecessarily high utility bills. So should you just go out and buy the largest-capacity equipment to be safe? No. An oversize system is just as bad as an undersize system. You'll pay too much for the equipment and more complex installation. Beyond that, you'll get poor performance, as a too-big system will operate inefficiently and also increase your utility bills. Oversize furnaces can cause big temperature swings, while outsize A/C units fail to properly dehumidify your air because they don't run long enough.
Correctly sizing your HVAC system is a more complex process than reading the label on your existing unit. That "nameplate" doesn't factor in important considerations that are unique to each home. When performing your home's load calculation, your HVAC professional should consider:
