System Age
Under 10 years: repair almost always wins. 10-15 years: depends on repair cost (see 50% Rule). for years: replacement usually wins — old systems lose 1-2% efficiency per year and parts get scarce.
The 50% Rule: if a single repair costs more than 50% of replacement cost AND your system is past 10 years old, replacement usually wins on total cost of ownership. Below, the framework we use on every Central NJ estimate.
Six honest tests we run before recommending either path.
Under 10 years: repair almost always wins. 10-15 years: depends on repair cost (see 50% Rule). for years: replacement usually wins — old systems lose 1-2% efficiency per year and parts get scarce.
Repair cost > 50% of replacement cost = lean replace. Example: 12-year-old AC needs $2,800 compressor; new system $7,000. Repair = 40% — borderline. Add another likely failure in 2 yrs ($1,500) = 61% — replace wins.
R-22 (Freon) systems = replace. Banned since 2020. R-22 prices are $150-$200/lb (was $20). Any major refrigerant leak on R-22 unit means $1,500+ to recharge. R-410A or R-454B = repair fine.
If your last 2 summer bills jumped 20%+ vs prior years (without a usage change), the system is losing efficiency. Combined with age > 12 yrs, lean replace — new SEER2 systems cut 30-50% off cooling costs.
3+ service calls in 18 months = replace. Once a system starts failing, the next failure isn’t far behind. The repair-Whac-A-Mole game costs more long-term than a new system.
Hot/cold rooms, weird noises, humidity problems, fan running constantly — these aren’t single-repair fixes. They’re symptoms of a system that’s done. New systems also come with 10-year parts warranties & our available workmanship support.
