Mini splits for Washington State —
heat pump AC & heating, best utility rebates in the US
Washington's mild but rainy Pacific Northwest climate is perfect for an inverter heat pump. Replace both your gas heat and summer AC with one system — and stack Puget Sound Energy, Seattle City Light, and federal 25C rebates worth up to $5,000. Cooper & Hunter, OLMO, and BRAVO ship free from Medley, FL to every Washington ZIP code in 5–7 business days.
Why heat pump mini splits are ideal for Washington homes
Washington's marine west coast climate (Climate Zone 4C–5C) brings mild but relentlessly damp winters, cool summers topping 70–75°F in Seattle, and persistent overcast. A heat pump mini split is the single most cost-effective solution: it replaces both your gas furnace and central AC while delivering year-round comfort at 200–400% energy efficiency. With state and utility rebates stacking on top of federal 25C credits, the payback timeline in Washington is among the shortest in the country.
