HVAC in Hanover Park: what the local homes and climate mean
The median home in Hanover Park was built in 1976, and about 67% were built before 1980. 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.
DuPage County is in IECC climate zone 5A, a cool, humid climate, on the U.S. Department of Energy's county map. 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 86% of occupied homes in Hanover Park heat with utility gas and 10% 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.
Permits and licenses in Hanover Park
Replacing a furnace, air conditioner or heat pump usually needs a mechanical permit and a final inspection. In Hanover Park, permits come from the city's building department, or from DuPage County for addresses outside city limits. Ask the company who pulls the permit, and keep a copy of it.
