Armstrong Air – Heat Pumps

Armstrong Air - Family of Products

The Armstrong Air™ 4SHP18LT heat pump. Chosen with confidence by people who expect and deliver excellence. Choose the 4SHP18LT heat pump for your home and experience a higher level of comfort. Comfort you can count on for years to come. It’s a smart choice. Because it’s The Professional’s Choice.


Two-stage operation maintains a consistent temperature throughout your home. Since the 4SHP18LT can run at a lower capacity during milder weather, it can use longer, gentler, more-efficient heating and cooling cycles. During extremely hot or cold weather, though, it can ramp up to a higher capacity to keep you comfortable. The 4SHP18LT is also designed to be dual-fuel compatible, meaning it can be combined with a gas furnace for increased comfort and energy efficiency throughout the year.
