Quick answer: New central AC in Bergen County is sized by a load calculation on the house, not by matching the old unit or by square footage rules of thumb. An oversized system short-cycles and leaves the air humid. In homes with boiler heat and no ducts, ductless is usually the cheaper and less invasive route.

Sizing decides whether a new central system performs, and it is calculated from the house rather than copied off the old unit. An oversized condenser satisfies the thermostat before it has run long enough to pull humidity out of the air, which is why an overspecified system can leave a house that is cold and still clammy. The other half is the ductwork it inherits: leaky or undersized returns waste a meaningful share of the capacity you just paid for, so we assess the duct system before quoting the equipment.
