Donwel Heating & Air Conditioning

We had been using this guy to repair our ground source heat pump for the longest time, because we had thought other services couldn't deal with that kind of a system. He specialises in ground source heat pumps. He's very squirrely and constantly pushing back times for deliveries and repair work. We recently found another company and had them install a thermostat. Apparently the guy at Donwel had wired everything up correctly, but used the wrong colour coded cables to connect. Easy for him to understand, but not others.
