The 5-Year Rule and AC Replacement Guide

Deciding whether to repair or replace your AC unit is a common dilemma. A good rule of thumb is the \"5-year rule\": if your unit is less than 5 years old and the repair cost is less than one-third of a new unit, repair is often the better option. For older units, or if repairs are frequent and costly, replacement becomes more sensible. Consider the age of your unit combined with the repair cost. If your AC is over 10-15 years old and a major repair is needed, investing in a new, more efficient unit will likely save you money in the long run. Modern units boast significantly higher SEER ratings, meaning lower energy bills. Signs of failure include frequent breakdowns, strange noises, uneven cooling, or a sudden spike in energy consumption.
