Overview of Trane XV18 4 Ton 18 SEER2 Heat Pump 4TWV8X48A1000
The Trane XV18 4 Ton 18 SEER2 Variable Speed Heat Pump 4TWV8X48A1000 is a premium 48,000 BTUh outdoor heat pump designed for homeowners who want efficient year-round heating and cooling, quieter operation, better humidity control, and more consistent indoor temperatures. Its variable-speed operation adjusts output instead of repeatedly running at full capacity like a basic single-stage system.
If you are comparing a Trane 4 ton AC unit for replacement, the XV18 heat pump gives you both cooling and heat-pump heating from one outdoor unit. It is especially suited to homeowners upgrading from an older central AC or heat pump who want better comfort control and higher-efficiency performance.
The XV18 uses Trane’s Climatuff™ compressor, Spine Fin™ outdoor coil and communicating technology to provide precise system operation when paired with compatible Trane indoor equipment and controls. Its durable cabinet construction includes full-side louvered panels, a DuraTuff™ base pan and Weatherguard™ fasteners for additional outdoor protection.
This 4-ton heat pump has a nominal cooling capacity of 48,000 BTUh and is designed to work as part of a properly matched split HVAC system. Before ordering, confirm the compatible indoor air handler or coil, communicating thermostat or control, electrical requirements, refrigerant requirements and system sizing for your home.
