What Highland homeowners should know about HVAC
The median home in Highland was built in 1967, and about 73% 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.
Lake 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 85% of occupied homes in Highland heat with utility gas and 14% 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 70% of homes in Highland are single-family houses, and about 78% of occupied homes are lived in by their owners.
Permits and licenses in Highland
