It may be time for additional insulation if:

It is difficult to keep your home cool in the summer and warm in the winter
Your home has uneven temperatures

Insulation keeps your home warm in the winter and cool in the summer. Without proper insulation, the hot or cold air outside can seep into your living space, causing your air conditioner or heater to work harder than it should to keep your home comfortable. This can lead to higher-than-expected energy bills.
