<h3>What is a Property's Effective Age?</h3>
The effective age of a property can be described as the reflection of the true life of the property that is left remaining, based on the life expectancy that is typical of equipment or buildings that are similar to it and their usage.
So, when a property owner installs a new air conditioning system on a property, the air conditioning system, can cause wear and tear to the property which reduces how long the property can serve its purpose.
Therefore, we can conclude that the effect that the newly installed air conditioning system would have on the property's effective age would be: it decreases it.
