A split system pairs an outdoor condenser with an indoor air handler or furnace, and is the most common HVAC setup in clubhouses, offices, and smaller common buildings. Systems typically last 12-18 years and cost roughly $6,000-$15,000 per system installed in 2026, or about $2,000-$3,000 per ton. Reserve studies usually schedule replacement at 15 years; the condenser and air handler are often on slightly different clocks, so many boards replace them as a matched set to avoid refrigerant mismatches.

List each split system separately with its tonnage, install year, and refrigerant type. Systems still on phased-out R-410A or older refrigerants can force early full-system replacement rather than a compressor repair. Budget for line-set flushing, a new matched coil, and a code-required condensate and electrical update — these add $1,000-$2,500 that base equipment quotes routinely omit.
Change filters every 1-3 months, clear the condensate drain each spring, and keep an annual service contract that checks refrigerant charge, capacitors, and coil cleanliness. Keeping condenser coils clean and airflow unrestricted is the single biggest driver of whether a system reaches 12 or 18 years.
Hot, humid, and coastal climates shorten condenser life through long run hours and salt-air corrosion. Higher-SEER equipment and matched-coil replacements cost more up front but are increasingly required by code at replacement.

Set-aside = replacement cost ÷ useful life (12–18 years). A new installation funds toward the long end; an aging one needs catch-up funding — run the full calculator for that.
