Mini split systems typically last 1015 years under normal use. Consider full replacement if any of the following apply:
System age beyond 12 years with no major overhauls in its history
Noticeable energy-use spikes or electric bills increasing despite regular maintenance
Frequent refrigerant leaks, compressor failures or repeated repairs exceeding 50% of a new unit’s cost
Significant performance drop-off in heating or cooling output
Unavailability of replacement parts for older models
Replacement vs. Repair: Evaluating the Right Path
Repair can be cost-effective when a minor component malfunctions. Replacement becomes more economical when:
Total repair costs approach half the price of a new inverter-driven mini split
Warranty coverage has lapsed or the unit has multiple fault codes in a single season
Desired efficiency gains exceed 20% with newer ENERGY STARrated models
Homeowners plan a long-term stay and prefer the reliability of a factory-fresh system
A side-by-side cost comparison typically highlights long-term savings on energy bills, quieter operation and reduced service calls after a full replacement.
