PNW 21st-Century-Modern Remodel HVAC and Flooring

6 years ago

Hello,

We are in the midst of planning a major remodel to 1960’s mid-century house in Seattle to modernize and improve the flow. The house is 2200 sq-ft. The first floor (1700 sq-ft ) will have significant changes including moving walls and the upper floor with (500 sq-ft) will only have minor cosmetic changes.

We need some help to sort through the HVAC and flooring decisions. Wood floors are preferred in the first great room/kitchen/dining area (850 sq-ft) but we have a dog that has torn up the current oak floors. The alternative is a tile which we do like but are concerned about cold floors in the PNW. Carpet will be in the other areas besides bathrooms/laundry.

The HVAC system is being moved and needs replaced so that opens up options we’d like some help to sort through and down-select.

HVAC System Design

What is best way to get system design help and cost estimate for different HVAC designs? Should we approach reputable HVAC companies and get feedback and estimates? Are we responsible for picking the HVAC company or do we work through the general contractor?

Below are heating/flooring options we are considering.

1. A new (likely modulating) furnace and new A/C is the simplest path forward. If we have throw rugs, etc., do you think that will suffice in the Pacific Northwest with tile floors? Will we regret not having heated floors?

2. Is there a simple, cost-effective/efficient way to add under-floor heating to cut the cold of the floors, maybe using a new tankless water that will used for hot water needs or electric in a low density pattern?

3. Hydronic heating with minisplits is another option we are considering. This would resolve the underfloor heating issue but is it overkill? It would be nice from a comfort standpoint but what would be the rough cost for our size of house?

4. The last option is to put down hardwoods and live with the scratches and change the floors 10 years down the road. We got samples of a Lauzon hard maple and they seemed to scratch and dent easily, more than expected. Either live with that or maybe find a harder exotic.

Right now we are leaning on 1 and or 2 but are looking for more info to guide us.

Thanks!!!
