After calling almost every HVAC contractor in town, I finally found a good one. They actually did a real load calculation, measured air flow from the ducts, etc. The system I have in mind is a Bryant heat pump. FV4C air handler variable speed with tin plated coil. 226A heat pump 2 stage. t-6 thermostat with humidity control. Anyone with any experience with this system know if I'm making a good choice? The contractor is nate rated and factory certified.
