They installed a heat pump on our new house and it has been a complete disaster. It started leaking water from the second floor down to the first floor about 2 weeks after we moved into our house and they've been out 6 times to try and address the issue. The last time they came they completely broke our AC, it can't keep up with the heat from outside, it's currently 79 in our house when it's set to 72. On top of that it's still leaking.
