There was a quick response and within half an hour, from when l gave him a call, he was in my house looked at my combined heater and did everything possible to give us hot water. He went out to buy the part needed and fixed it. The boiler is as good as new now. He is very clean while working. He has good manners and is focused. Overall, I think he has a very good service and l will book this person again. I highly recommend him for anyone out there.
