The GLZS5 has a higher heating efficiency rating (HSPF2), which saves more in climates with real winters. In mild climates, the GLZS4 usually makes more sense. Do I need a heat kit? Most heat pump installs include one for backup and defrost heat. Size it to the home's heat loss: smaller kits suit mild climates, larger kits colder ones. Can I reuse my existing line set? Sometimes. Size and condition must suit R-32 and this system's specs. Your installer should verify the line set and flush it if it's being reused. Is this compatible with my old R-410A or R-22 equipment? No. Replace both the outdoor unit and the indoor unit together with this matched R-32 system.
