KEIL Heating and Air Conditioning

Keil installed our furnace in 2018. During recent single-digit temperatures, our upstairs heat stopped working, so I contacted them for service. To their credit, they sent a technician out the same morning. He blew out the condensate line, said the system was working, and left. About 30 minutes later, the heat stopped working again. When I called back, the call center told me I needed to wait a few hours for the system to start working. A technician later returned, and I explained that the condensate line drains to the roof and was frozen — meaning the initial “fix” was only a temporary band-aid that allowed the system to run briefly before shutting down again. Despite visible evidence (including a frozen condensate line), the technician did not acknowledge the routing of the line as th

I had my heating system serviced recently, and the technician went truly above and beyond. They were punctual, professional, and took the time to explain everything they were doing. What really stood out was their attention to detail — they noticed a small issue that could have become a major problem later and fixed it on the spot. They even checked areas outside the scope of the regular maintenance to make sure everything was running safely and efficiently. It’s rare to see someone take such pride in their work and genuinely care about customer comfort and safety. I couldn’t be more pleased with the service and will definitely be requesting this technician for future maintenance. Highly recommend!

Yoon has been to our house in the past. He is very professional and friendly. He explained everything very well. He will be back to fix an issue that was found after part is received. He's is an asset to your company.

As a loyal customer we chose the prepay option. After years of providing them with business, they refuse to refund our money from the prepay option even though we moved out of their service area. So much for customer service. While you may be a loyal customer, don't expect the same loyalty from them.

Didn't have a problem until they didn't want to take responsibility of mice getting into my attic from the hole they made for pipes to get in. 2 months after install it was wasps that made a nest where the pipes came in and they came into my room from the attic, got exterminator to get rid of wasps and Keil came back to seal the hole. Apparently to them its sealed even though any critter can come from the bottom where they installed pipes through a gutter that leads to opening right into attic. Exterminator came and got rid of the mice and had to copper mesh the hole they "sealed" and this time said that is basically my problem. Thanks definitely will not be paying you every year for maintenance. If that is how you deal with sealing for houses stay clear and go with a different company.
