-
Maintenance frequency

💸 When to Replace Instead of Repair
Use the $5,000 Rule:
Multiply the repair estimate by the age of the unit. If it’s over $5,000, replacement is more cost-effective.
Example:
-
$350 repair × 12 years = $4,200 → OK to repair
-
$450 repair × 13 years = $5,850 → Replace
Other signs you should replace:
-
Uses outdated refrigerant like R-22
-
Needs multiple repairs per year
-
Inconsistent performance even after servicing
-
No longer meets your room's cooling needs
