Great service! Technician was on time, knowledgeable and professional.

Our technician was so thorough and professional. He was on time and also very knowledgeable. I will recommend Keil to all of my friends.

As far as I can tell, he is efficient, knowledgeable, pleasant, and certainly seems sure of what he is doing. I have difficulty with his speech/accent but am pleased overall.

Mr. Yang was very thorough and professional.

Would rate higher, but on initial installation they installed wrong size flew pipe, which caused me to flunk inspection. They came back to install correct pipe

Prompt, friendly , knowledgeable

I left for work after Keil arrived at my house. My wife was home and told me she was very happy with the 2 techs that installed the ductless air conditioner. They were respectful and put down drop cloths and mats. They did a great job and left the house as clean as it was before they got here. I would recommend Keil for all your plumbing, heating and a/ c needs. I have had Keil install my furnace, hot water heater and would recommend them always. Great price and Great Service !
