I bought a 74′ Split-level 4 years ago in Oregon just outside of Portland.
Last year we had 115+ degree temperatures w/ humidity, this was 10 degrees above the highest ever recorded. The year before we had nearly a week straight of 105+ w/ humidity. Extreme Heat waves seem to be an every-year thing here now. When I bought the home my agent said it has the ducting in place already to add an AC unit ( gas duct heating, pipes in from floor grates ), he said adding an AC unit would only run a few thousand dollars.
I recently asked a contractor I had on site for another job about it, but he said 3k was optimistic. There is a small Slab out back where it looks like AN AC unit would go, theres an electrical conduit, too, strapped against the wall.
I’m just looking for a ballpark figure, it’s a 2200 sq ft home, what would adding a whole-home AC unit cost? I’m also curious about mini-split systems, but since I already have the ducting in place I’m not sure that is the best option?
Also, very stupid question, but the slab/conduit behind my house… if that’s for an Air conditioning unit, There’s no duct in that area, so how does a system like that work? ELI5.
