I had an issue with water heater. Tech named Lorne from dupont came in. He was on time however he had no sense of direction when it came to water heater. Not impressed with him at all. He opened up gas cascade when there was no need for it. Now I have to replace gas cascade and had to hire someone else to fix it. He just created more work then he needed to. I called another company and tech was able to figure issue in 10 minutes where as DuPont tech spend 1.5 hour messing around. I even called dupont to qestion their tech's qualifications and they told me he is qualifed. He might be qualified however he is to not efficient at all. I will never call this company again.
I have posted same review at home stars.
