More capacity, same high-efficiency comfort — heating and cooling for larger homes in one unit. The Goodman GLZS5BA4210 steps up to 3.5-ton heating and cooling at 15.2 SEER2 / 8.2 HSPF2 for larger homes that need more capacity from their heat pump system. Energy Star certified and approved for all 50 US states — this unit delivers approximately 12% better cooling efficiency than standard 14.3 SEER2 heat pumps while providing reliable heating through mild to moderate winters. The same SmartShift® technology and seven factory-installed protection components as the rest of the GLZS5BA lineup — built tougher for larger heating and cooling demands.
