Frequently asked questions

Is AC age enough to decide replacement?

No. Age matters, but repair cost, recent failures, comfort, efficiency, and the actual failed component also change the decision.

Does a major repair automatically mean replace?

No. A major repair raises the replacement question, but the decision should compare repair scope with the system's broader condition and replacement cost.
