Carrier 14S Air Conditioner 2.5 Ton 13.4 SEER2 R454B

Product Description

The CARRIER 14S is a 2.5-ton, single-stage residential central air conditioner charged with R454B (Puron Advance) refrigerant. It delivers a 13.4 SEER2 efficiency rating and operates on a 208/230-volt, 1-phase, 60 Hz power supply. The unit uses a scroll compressor, a thermostatic expansion valve (TXV) metering device, and a direct-drive propeller-type condenser fan motor rated at 1/10 horsepower and 825 RPM. Cabinet orientation is vertical. Licensed HVAC technicians install this unit as the outdoor condensing section of a split-system cooling setup.

The 14S is designed for standard North American residential cooling applications. It fits into split-system configurations requiring a 2.5-ton outdoor condensing unit paired with a compatible indoor coil and air handler. The Comfort series designation places this unit in Carrier's value-tier lineup, making it a common choice for straightforward residential replacement and new-construction installs where a single-stage, non-communicating outdoor unit is specified.

Compatibility

Designed as an OEM-style replacement or new-installation outdoor condensing unit for residential split-system air conditioning setups requiring a 2.5-ton, single-stage, R454B-compatible outdoor unit with 208/230-volt 1-phase power.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician due to the refrigerant handling requirements of R454B. Disconnect and lock out all electrical power before servicing the unit or making refrigerant connections. Verify that the indoor coil and air handler are rated compatible with R454B refrigerant and sized for 2.5-ton capacity before commissioning. Observe local mechanical and electrical codes, including NEC requirements for minimum circuit ampacity (MCA 16 amps) and maximum overcurrent protection (25-amp breaker).
