H Yang serviced my furnaces today and he did an excellent job. He is a highly capable service technician and was a pleasure to interact with.

Asanti completed my yearly service cleaning and tune up efficiently and quickly. He answered all my questions and told me what he was doing and why. He fully explained to me the workings of the unit which gives me the confidence that the unit will provide all my heating and hot water needs without any issues.

Excellent service, thorough and efficient. Thank you!

easy to make an appointment - very prompt, really appreciate the call to let me know the tech is on his way. Friendly personnel - have been dealing with Keil for over 15 years. The warranty on our heater and AC makes it very convenient for the yearly maintenance. Would and have recommended Keil to family and friends.

Nice

customer service excellent - technician arrived on time - really appreciate the call to let us know he was on his way. Totally reliable, haven't had a problem since the furnance and AC were replaced. Well worth paying for the warranty service. Thank you Keil. Will continue to recommend your services to others.
