Armstrong Air 4SHP18LS Heat Pumps

Armstrong Air 4SHP18LS Heat Pump Overview

The Armstrong Air 4SHP18LS is a two-stage heat pump with an efficiency rating of up to 18 SEER and 9.2 HSPF. High- and low-pressure switches and a bi-directional filter drier protect the two-stage scroll compressor, and a grommet mounted compressor design and heavy-duty compressor sound blanket help keep operating sound levels as low as 72 decibels. An enhanced aluminum fin and rifled copper tubing coil provides improved refrigerant flow for optimal heat transfer and efficiency. The unit can be paired with a Comfort Sync thermostat, allowing remote temperature adjustment while continuously monitoring the system. External gauge ports and controls located in a corner post offer easy serviceability, and a self-diagnostics feature saves the previous 10 fault codes. A durable galvanized steel cabinet with a baked polyester paint finish protects the unit from weather hazards.
