Your AC is broken or failing. The repair quote just came in. Now you're wondering: should I fix this aging system or replace it entirely? This is one of the most common questions we answer for homeowners, vacation rental hosts, and property managers in Lake Buena Vista and the Orlando area. Here's how to think through it.
The $5,000 Rule (The Industry Standard)
The most widely used decision framework in the HVAC industry is the $5,000 rule: multiply the repair cost by the system's age in years. If the result is over $5,000, replacement is usually the better financial decision.
Example: Your 9-year-old AC needs a $650 compressor repair. 9 × $650 = $5,850. The math says replace — especially in Florida's harsh climate where that 9-year-old system has additional wear.
This rule isn't perfect, but it's a useful starting point. Here are more specific factors for Lake Buena Vista homeowners:
Repair: When It Makes Sense
Repair the AC When...
- System is under 8 years old
- Repair cost is less than 30% of a new system's cost
- The failure is a single component (capacitor, contactor, drain line)
- System is under manufacturer's parts warranty
- The rest of the system has been well-maintained and is in good condition
- You plan to sell the property within 1–2 years (replacement may not add value)
Replace: When It Makes Sense
Replace the AC When...
- System is 12+ years old (10+ for Florida — year-round use ages systems faster)
- This is the second or third major repair in 2–3 years
- The compressor has failed on an out-of-warranty system
- Electric bills have been rising steadily despite no usage changes
- Refrigerant type is R-22 (Freon — discontinued and extremely expensive)
- System uses R-22 refrigerant (phased out, refill costs $200–$600+ per pound)
- Repair cost is over $1,500 on a system older than 10 years
AC systems in Lake Buena Vista and Orlando run year-round — roughly 2,500–3,000+ hours per year vs. 1,000–1,500 hours in northern states. This means a 10-year-old Florida system has the equivalent wear of a 20-year-old system in a cold climate. We factor this into every replacement recommendation.
