Zone 4

Your Climate Zone

Washington is in IECC Climate Zone 4. Zone 4 is mixed — moderate summers, cold winters (10–25°F lows). Heating and cooling loads are roughly balanced. This affects what size and type of system you need: since you get both hot summers and cold winters, the system needs to handle both.

A Washington home under 1,500 sq ft typically needs a 2-ton system ($5,210–$9,436), while homes over 3,500 sq ft need 5 tons ($8,936–$15,404).

5.7¢/kWh

Your Electricity Rate

This is what you pay per kilowatt-hour of electricity through Potomac Electric Power Co. It matters because a heat pump runs on electricity — so your electric rate directly affects how much it costs to heat and cool your home. Your rate is well below average — even a standard-efficiency system will be cheap to run.

What's SEER2? It stands for Seasonal Energy Efficiency Ratio — think of it like MPG for your car. A 20 SEER2 system uses about 25% less electricity than a 15 SEER2 system. At Washington's rate, that's roughly $97/year saved on heating alone.

What's the difference between ducted and ductless?

A ducted heat pump connects to the air vents already in your walls and ceiling — if you have a furnace now, you probably have ducts. It heats and cools the whole house through those vents. A ductless mini-split uses small wall-mounted units in individual rooms, connected by a thin pipe to an outdoor unit. It's ideal if you don't have existing ductwork, or want to control temperatures room-by-room.
