I suspected I had a carbon monoxide leak from my furnace and they were out at my house in 15 minutes. He put a meter on the furnace and it showed a leak. He turned off the pilot light to take care of the immediate problem. I asked him about alternate heating sources and I was called that afternoon. Pat showed up to look at my house to be able to give me my options. He took time and explained everything. He worked hard to get me a good price and looked for rebates on the heat pump. I am very satisfied with the service and will continue to call Island Heating for all my heating/cooling needs.
