His service was excellent. !

The two gentlemen who provided my service were polite, considerate, efficient ..worked very "clean". They worked 6 hours without a break and never complained. They did a great job!

Technicians were neat, helpful, and pleasant to have at the house

Service person on time. Did the service check quickly. Pleasant person.

We had our heating unit serviced by Yang a tech from Keil. He was very professional and gave us a detailed explanation of everything that was done. We are pleased with our annual maintenance agreement with Keil and would recommend their service.

Mr. Yang arrived on time and explained everything he'd be doing before he started, as well as the charges that would apply for each part. Job was done quickly and thoroughly, so we're all set for another winter.

Yoon always provides great service

Mr. Yang was thorough and efficient

Very nice work, the technician alertly found a potential serious leak in my expansion tank which, left unattended, would result some day in a massive leak and flooding of my basement. He collaborated well with me in evaluating another potential problem, a possible leak in a relief valve. We decided together that it was best to do nothing, observe the valve for a while to see if it leaked because the small leak he spotted may have been caused by a sudden pressure surge when he replaced the expansion tank. After a few days now, that seemed to be the cause of the leak as the valve has not leaked a drop now during normal operation for several days- a good decision we made together.

Dave and Sam came to remove the 28 yr old furnace and put a brand new gas furnace in its place with all new piping and parts. They were on time, courteous, professional, organized and did a GREAT job. Afterwards they had to bleed all the lines which took a while in this old house. Their attitude was positive and friendly. We've used Keil for probably most of the 65 years this house has been in existence. We rely on them and they have never let us down.

Mr. Yang was professional, courteous and took time to explain the costs involved for today's service. All actions that I very much appreciated.

Yang was great as always. Professional, kind and explains everything! Great job!

Yoon is very professional and very knowledgeable. I feel I am in good hands with him as service technician.

The technician did a great job of checking my heating system and getting it ready for winter. He changed the humidifier pad, first asking me if I wanted that, which I did as it is important to change it each year. He set the humidifier for 35%, which is the recommended level for winter. He explained to me everything he did at the end of his work., which gave me an even better idea of how thorough he was. He was professional, knowledgeable, pleasant and neat. And I would like to have the same technician back next spring for the A/C tune-up, and for all future Keil visits to check my heating and A/C systems.
