What Is the $5,000 Rule?

Multiply the age of your air conditioner by the cost of the repair. If the total exceeds $5,000, replacement is usually the better option.

Example:

• 12-year-old AC × $500 repair = $6,000 → Replace
• 5-year-old AC × $400 repair = $2,000 → Repair

This rule helps homeowners in McKinney avoid sinking money into aging systems.

Why the Rule Matters in North Texas

With long, hot summers in McKinney, your AC works harder than in many parts of the country. Older systems lose efficiency, struggle to keep up, and often rely on outdated refrigerants like R-22 refrigerant, which are expensive to service.

When Replacement Makes More Sense

Even if you’re under $5,000, consider replacing if:

• Your system is 10–15+ years old
• Repairs are becoming frequent
• Energy bills keep rising
• Cooling is inconsistent

Benefits of Replacing Your AC

A new system offers:

• Lower energy bills with higher efficiency ratings
• Improved comfort and airflow
• Quieter operation
• Increased home value

Bottom Line

The $5,000 rule is a quick, practical tool—but it’s not the only factor. A professional evaluation ensures you choose the most cost-effective and reliable option for your home.
