Should I Repair or Replace My AC? — The $5,000 Rule

Professional Should I Repair or Replace My AC? — The $5,000 Rule in Asheville & Western NC

The $5,000 Rule: A Quick Decision Formula

Multiply the age of your AC (in years) by the repair cost. If the result exceeds $5,000, replace. If it's under $5,000, repair. Example: A 12-year-old AC with a $500 repair = $6,000 → replace. A 5-year-old AC with a $800 repair = $4,000 → repair. This simple formula accounts for the fact that expensive repairs on old equipment are poor investments, while even pricey repairs on newer equipment are usually worthwhile.

Factors Beyond the Formula

The $5,000 rule is a starting point, not the final answer. Consider also: Does the system use R-22 refrigerant (phased out and expensive)? Has the system had multiple repairs recently, suggesting a cascade of failures? Is the system properly sized for your home? Is your energy bill significantly higher than neighbors with similar homes? Are you planning to sell the house soon (a new system adds resale value)? These factors can tip the decision even when the $5,000 rule says repair.

The Hidden Cost of Keeping an Old System

Every month you run an aging, inefficient AC, you're paying an "inefficiency tax" on your electric bill. A 15-year-old, 10 SEER system costs roughly $150–$200/month to run in peak Asheville summer, while a modern 16 SEER2 replacement would cost $90–$130 for the same cooling. That $50–$70/month difference adds up to $300–$500 per cooling season — money that could be reducing the cost of a new system. Add in the stress and inconvenience of breakdowns, and the math often favors replacement sooner than you'd think.
