Trane A5AC4018A1000 Split System Air Conditioner 18000 Btu 14.3 SEER2 1.5 Ton R-454B

Product Description

The Trane A5AC4018A1000 is a 1.5-ton single-stage split system air conditioner condensing unit built under the RunTru by Trane product line. It operates on R-454B refrigerant and carries a 14.3 SEER2 efficiency rating, making it compliant with current federal minimum efficiency standards. The unit runs on a 208-230V, single-phase, 60 Hz power supply with 24-volt system control. Cooling capacity is 18,000 BTU/h. The all-aluminum coil construction resists corrosion in typical outdoor environments. Licensed HVAC technicians install and commission this unit as the outdoor condensing section of a matched split system.

The A5AC4018A1000 is designed for residential central cooling applications where a compact 1.5-ton system capacity is appropriate. It pairs with a compatible indoor evaporator coil and air handler or furnace to form a complete split system. It is suited for single-zone residential installs requiring a low-refrigerant-GWP solution that meets current regulatory requirements for new equipment. This condensing unit is part of the RunTru by Trane value-tier lineup, positioned for straightforward replacement and new-construction installs in smaller conditioned spaces.
