Dave has been very pleasant and respectful the moment he called to tell me his ETA. His demeanor made me comfortable. He explained things well with me...gave me information I needed and respected my home. I feel like the issue is still there but I am also aware that my eater heater is old and needs to be replaced some time soon but overall, he did a great job! Thank you!!!! Btw...whoever answered my call for an appt (I forgot the name) was great too! Good customer service!
