The team at World of Comfort was fantastic from start to finish. They were friendly, and went a long way towards explaining everything to us about how things worked. We ended up with a transformed heating system for our water and rads and we couldn't be happier. Not only is it more energy efficient, but now there's never any worry of running our of hot water and the unit takes us so much less space in our basement then the old water tank and furnace. We couldn't be more positive about these guys!!
