Deciding to repair or replace your AC depends on age, efficiency, and cost. If your system is under 10 years old and the repair is minor, fixing it is usually cost-effective. However, frequent breakdowns, major component failures, or refrigerant issues in older units may justify replacement. Consider energy efficiency: newer systems use less electricity and reduce bills. Also, evaluate repair cost versus replacement price; if repairs exceed 50% of a new system, replacement is wiser. A certified AC technician can inspect your unit, provide estimates, and recommend the most practical, long-term solution.
