Questions
Is it worth repairing instead of replacing my AC?
As a rule of thumb, if the repair is more than a third of the replacement cost or the unit is over 12–15 years old, replacement often makes more sense.
Does a new AC increase home value?
A new, efficient system can improve appeal and is a common selling point, though it typically doesn't recover the full cost.
