What Sycamore homeowners should know about HVAC
Census estimates put the median build year in Sycamore at 1993; about 16% of homes were built before 1950. Equipment installed when many of these homes were built is at an age where repair-or-replace decisions come up. Ask for both options in writing.
The U.S. Department of Energy places DeKalb 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.
About 81% of occupied homes in Sycamore heat with utility gas and 18% with electricity. Many replacement quotes will involve a gas furnace or boiler; if you are thinking about switching to an electric heat pump, ask whether your electrical panel needs an upgrade.
