Carrier infinity/bryant evolution, greer... Mitsubishi mini split (heat pump) hold their own to a point (and up front price). But that is going to dc and staging.Would not recommend them for North of the Mid South. Once that emergency heat kicks on you are going to need the Emergency room for when you see the Bill. We have one and use it for AC only, for the most part it’s good at cooling but our home is well insulated so there is that.
