We had a sever leak in out basement that caused us to have to replace both our hot water tank and our furnace. We had Viking come take a look and the man who came was very knowledgeable and helpful, explaining to us the reasons the products needed to be replaced. After talking it over with my wife we decided to go ahead with the replacement, and before the end of the week they had our old products replaced. The installers were on time and polite and kept the work area clean. Even when we has an issue after the install with the furnace not working, they we back out the next day to take care of us. It was great service!!
