Recent Review: The gentleman I spoke to on the phone was very nice and helpful. He took his time explaining the process and asking questions about the water heater that was leaking. I had been trying to get Lowe's to come out and measure for a replacement for four days so it was quite a relief to talk to a person who actually knew what he was talking about. He gave me a full quote on the phone and set up the appointment for the next day. The repairman arrived on time and worked very hard to replace the unit...it was quite hot in the garage that day. The install was more tricky than a traditional water heater as mine is a direct-vent style. He took the time to explain the process and when he had finished, he explained what he had done installing the new pipes and how to use the heater settings. I was very impressed with his work ethic and professionalism. He cleaned up everything after the replacement and caulked around the heat vent which was something lacking with the previous heater. I really couldn't have asked for more. Next time I need anything plumbing-related I will call Kessler first and skip the big box store hassle.
