Repair if your AC is under 10 years old and the repair cost is less than one-third of a replacement unit; strongly consider replacement at 12-plus years, for R-22 systems with leaks, or when the repair exceeds half the replacement cost.
The repair-or-replace decision for a Sacramento AC comes down to three factors: age, refrigerant type, and repair cost relative to replacement.
Repair is almost always the right call if the unit is under 10 years old, the refrigerant is R-410A or newer, and the repair runs less than one-third of a new-equipment quote. A $450 capacitor-and-contactor service on a seven-year-old system is a clear repair.
Replacement starts winning at 12-plus years, and it wins decisively for R-22 systems with a refrigerant leak. R-22 has been out of production since 2020, and every year the cost per pound climbs. A $1,500 repair on a 14-year-old R-22 system with a leaking evaporator is throwing good money after bad — a new high-SEER2 heat pump installed runs roughly $7,000 to $12,000 and cuts summer electricity bills by 20 to 40 percent per ENERGY STAR data.
In between — a 10-to-12-year-old system with a major repair — the math gets closer. Factor in current SMUD heat-pump rebates (quoted at the estimate; amounts change). The federal §25C credit is not allowed for equipment placed in service after December 31, 2025, so do not count a $2,000 federal credit on a 2026 replacement.
We'll quote both paths on any system older than 10 years so the decision is yours with real numbers.
