I bought a house with two air heat pumps. I live in France. One day it stopped working. I tried to find a contractor to repair it. It was hard. Too long to wait in the winter. I immediately bought electric heaters to replace the heat pump as wiring was already in place (the heat pumps were already v2 of the house heating). I finally got one contractor to come for the heat pump. It happened that he came to my home the only day the last 3 years that temperature was below -5 °C. The issue was apparently a gas leak, but because of the low temperature he couldn't do anything. Despites my calls, he never came back. And I haven't been able to get someone else to fix the thing. The only other contractor I found was only asking 250 EUR to decommission the thing. So I still have a non working air heat pump in my living room.
