Bucky-
I saw on the Xcel bill thread you looked I to efficiency options through your build. Did you look into two stage versus single stage HVAC equipment? If so, I’d be curious on what you found
We went with 2 stage, but mainly because the in-laws own and run a commercial HVAC business and getting the equipment at their cost made it more affordable. Had we not had that advantage, the 2 stage option may have been cut.
Their thoughts as the experts were that although the 2 stage is more efficient – insulation, overall design of the house, and materials used in key areas will produce better bang for your buck in savings down the road if we had to choose.
Money is finite, so what we did was prioritize things that we thought would give us the best return on investment – or pay for themselves first over time whether it be because they help with efficiency or their lifespan. I know a 2 stage furnace was not at the top of that list. For sure the spray foam, upgraded windows, ICF foundation, and LP Smartside were ahead of the furnace on our list.
