Great service technician

Always great service, clean and neat work.

Excellent technician

The installation of our new a/c condenser and coil was a positive experience. The technicians arrived on time and completed the job within the timeframe they laid out before they began. The work was done in a very professional, efficient manner. They used runners over my carpets to prevent tracking of dirt. The job site, both inside and outside, was left clean and free of debris. The old equipment was hauled away. That’s why I’ve been with Keil for 20 years.

Mr. Yang is very professional and courteous.

Everything went well. The technician arrived at the appointment time and he wore a mask for anti-virus precaution. He was thorough in his maintenance and shared his professional advice about keeping the condenser clear of grass, leaves and debris, and periodically changing the unit filter, which he kindly did. Pleased with the experience, I signed up for Keil's annual maintenance plan.

John performed the annual maintenance on my air conditioning system. He is quite detail oriented. He left everything neat and clean and even offered helpful advice on various home issues.

Technician was careful to sanitize everything, which was greatly appreciated.

Mr Yang performed winter service on my furnace. He is so particular and throu. He also installed a carbon monoxide detector in my laundry room and water sensor. Mr Yang had been here before. He is always so pleasant and gives you all The details of the service he is providing. He is excellent and I feel very comfortable when he comes. Excellent technician and lovely person. Thank you

John provided a great service experience, checking out the furnace. He took the initiative to alert me to other things around the house that I should be doing like cleaning the dryer duct vent. I appreciated his professionalism.

We've always had good service with Keil. Your technicians are the best and we feel confident that they are doing a good job.

Thanks for scheduling me so quickly and arriving on time, as promised. Keil has installed my boiler and water heater, as well, in recent years. They have a history of doing the jobs right for me, both of which were very challenging, and I'm confident my new central AC is another job well done!

I had asked the service tech to arrive while I was home from work on my lunch hour; and he was there when I arrived and I even had time to spare before returning to work? So responsible and reliable! Awesome! I'm so happy! Thank you!

Yoon is a consummate technition. He explains all and does his work without fuss. Provides that little extra.

he Keil Service Reps are professional, courteous, and very knowledgeable. They explain everything to you as they go through the service process. I have never had a bad experience. Thank you all for your great service!!

Worked quickly and was careful to work clean. Unfortunately he didn’t have the replacement air filter, so Keil will need to schedule another appointment.

Yoon is by far the best tech I have experienced with Keil. Not only was he professional and courteous, he exhibited knowledge Of his task and showed me exactly what he found wrong and followed up with how he would correct the situation. All this made the price worthwhile. In the future I want Yoon to be sent for my service. I anticipate service for AC in late spring or early summer, but Yoon must be the tech.

Excellent and efficient job of installing our new furnace. We have been customers of Keil's for many, many years and are very happy with the services they provide.

Always great service

Dan and Sam were outstanding. On the most miserable day of the winter, they completed the job. Pleasant, professional, no complaints, great crew. they were neat and cleaned up after the job. Every Service company should have a crew like Dan and Sam. Thanks so much.

Installation went smoothly, as they were careful to work cleanly.

Called the Emergency number on Wednesday night. Received call back within an hour. By 8 AM Thursday morning, I received a call to schedule a service call. Tech was here by 12 noon on Thursday. Yoon was very pleasant and knowledgeable. I had heat by 2 PM. Hoping this will get me through this winter and will be installing a new furnace and AC unit in the spring. Thank you Kiel and Yoon for great service.

Randy is always very cordial and answers all my questions. Great Service. Thanks Randy and Kiel.
