Darren **** did a great job getting my cooling system ready for the summer. I was very pleased that he brought to my attention a problem with my hot water heater that was located close to the furnace. He could hear drips and went to the hot water heater to notice it was dripping directly under the heater. So appreciate that. I may have had a major problem before I would have noticed it.
