We gave the house we moved into a year, to see how it was. It has no air conditioning in it, but it is sitting in a grove of trees on a hill. A month and a half ago or so, I decided we should get AC installed.
This is no easy task for this house, because all of the heating is radiant heating... silicone tubes run underneath all of the hardwood floors, so there is no blown air anywhere. It's really nice when your feet land on a warm floor in the morning, and it holds a very stable heat, but this system won't work for cooling the house. Thankfully, they did leave much of the old ductwork intact (much, but not all).
We couldn't go the route of just an in-window air conditioner either, due to the type of windows we have in the house. And it got uncomfortable enough on enough days that we decided to go for it.
Yes, Virginia, it does get hot in Upstate NY.
We went with a central air conditioning system, splitting the house into 3 zones. In the 90+ degree heat we're experiencing currently, I'm damn glad we had it put in. Adds to the value of the house, too.
Good luck with your AC, bfreebern. If I had to guess, either the system isn't set to Cool, or it's busted.
