Your Best Choice for Furnace and Air Conditioning Repair in Kinnelon NJ

I can’t really get into technical terms. The man explained everything that I should be concerned about. He did not push for me to replace with them. Also, one of My thermostats needed new batteries and he cleaned it up for me and replaced the batteries. Thats something he didn’t have to do.

Heejun Yang always does an excellent job. He has serviced my heating and AC units multiple times.

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.
