HVAC in Techny: what the local homes and climate mean
The U.S. Department of Energy places Cook County in climate zone 5A (cool, humid). Heating carries most of the load here. If you are considering a heat pump, ask whether the model is rated for cold climates and how backup heat works. In a humid climate, ask how the system will control indoor humidity, not just temperature. Whatever the climate, ask for a room-by-room load calculation (ACCA Manual J) instead of matching the size of the old unit.
Permits and licenses in Techny
