GLZS5

The Goodman GLZS5 is an R-32 split-system heat pump engineered for reliable, energy-efficient heating and cooling. Available from 1½ to 5 tons, it provides an affordable year-round comfort solution for a wide range of homes.

Comfort

The GLZS5 delivers dependable heating and cooling throughout the seasons. Its defrost controls help maintain reliable performance during cold weather.

Efficiency

With ratings up to 15.2 SEER2 and 7.8 HSPF2, the GLZS5 provides efficient performance that can help reduce energy use while keeping your home comfortable.

Technology

Goodman’s SmartShift® technology helps reduce the disruptive sounds commonly associated with heat-pump defrost cycles.

When defrost is needed, SmartShift briefly delays the compressor before the reversing valve changes position. This allows system pressures to equalize, creating a smoother, quieter transition before the compressor restarts and clears ice from the outdoor coil.
