HVAC in Hoffman Estates: what the local homes and climate mean
Census estimates put the median build year in Hoffman Estates at 1976; about 12% were built in 2000 or later. Many homes from this era still have their original ductwork. Leaky or undersized ducts can hold back a new system, so ask for a duct check with any replacement quote.
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.
About 89% of occupied homes in Hoffman Estates heat with utility gas and 7% 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.
About 60% of homes in Hoffman Estates are single-family houses, and about 74% of occupied homes are lived in by their owners.
