HVAC system recommendation
My husband and I are in the process of building a semi-custom home in Seattle/Pacific Northwest (WA) and have no clue as to which HVAC system to go with.
The house is about 4,900 sq ft excluding the garage area. We have an accessory dwelling unit on top the garage which square footage is a little over 1,000 included in the house sq ft. We will use that space as a rental and live in the remaining 4,000. Our living room is a double story. The walls on the first floor are 9′ and 8′ on the second. We will have a gas fireplace in the living room and have triple pane windows installed.
Here are the energy guidelines we have on our plans which I understand are just minimum requirements.
Our architect also included a 3.5 WA energy credit notes on the plan to add more efficiency to the house. We are looking for:
1. a very efficient system
2. natural gas is an option as well as electricity
3. will ductless heat pump be an ideal solution for a house that size?
4. a combo heating/AC
Could you please give us some input as to which HVAC system can potentially work for us?
Thank you all so much!
