HVAC Maintenance in Sussex, WI: What to Expect
Sussex sits within Milwaukee's Great Lakes continental climate, where winter lows hover around 14 F and brief summers push toward 83 F.

Furnace tune-ups run $82 to $227, while AC tune-ups range from $72 to $206. A full HVAC inspection typically costs $155 to $412.
