We’ve used Keil for years and find having service agreements with them great . Yang has serviced our furnace/AC many times and he does a great job. Very thorough and explains what he’s done. Excellent!

Your company always sends a competent, efficient and courteous employee.

Excellent service and maintenance

Mr. Yang was professional and thorough.

Thank you.

John was polite and nice and appeared to know what he was doing. I gave you a 5 for quality but personally it is not a fair question since I am not in a position to opine on the quality of the service. I don't believe this is a fair question to ask a customer who is not knowledgeable on AC maintenance and repair. As far as convenience I only gave you a 3. Every year I pay in advance for next year's service. I should be getting a call in May to schedule my service. Instead, every year I have to call. If I did not call, I wonder if I would have gotten a call from Keil. For those regular customers that pay in advance, it should be Keil calling early in the season to schedule maintenance and not leaving this up to the customer.

Hunter was exceptionally thorough and very personable. Enjoyed working with him.

Mr. Yang was very thorough - great job!

Serviceman was very fast in determining the reason for the problem with our furnace and explaining it to me before replacing faulty part..

Hunter provided excellent service and was able to perform the maintenance with a minimum of fuss

I have no problems with Keil or their representatives. Everything is explained clearly and understood.
