AC decision guide
Is AC Repair Worth It? Repair vs Replacement
A repair can be financially sensible even on an older system, while a large repair can be hard to justify on equipment with repeated failures, comfort problems, poor efficiency, or a major component issue.
The decision this page helps with

Frequently asked questions
Is there one repair-cost percentage that means replace the AC?
No. A percentage rule can hide important differences in age, repair history, major-component condition, efficiency, comfort, and replacement scope.
What information makes this decision more useful?
A diagnosed repair cost, realistic replacement planning cost, system age, recent repair history, efficiency, comfort problems, and whether a major component failed.
