When we bought our house there were no trees in the front yard that faces West. The rooms in the front baked in the summer. We planted two bradfords close to the house to shade the windows quickly, with larger, slow growing trees further out. They served their purpose, and we cut them down when they started splitting. I never noticed a bad smell.
A storm took down all of our large trees a few years ago, and yes, we have pear trees planted in front of the windows again, while we wait for the larger trees to grow. They are a different variety, but if they split once they are full-grown, they will have done what we needed them to do.
We were too concerned about property damage, to wait for disaster to happen, so we hired a tree service to remove ours. We didn't wait for it to split. It's also rather expensive to plant these trees continually & then cut them down later (or remove an already split one) unless you're willing & able to cut them down & grind the stumps yourself. Spending a lot of money to repair a damaged house or cars was not in our game plan. I'd rather just plant hardwood trees and have patience. Ours was on the West side, too.
