Your Best Choice for Furnace and Air Conditioning Repair in Kinnelon NJ (2)

customer service excellent - technician arrived on time - really appreciate the call to let us know he was on his way. Totally reliable, haven't had a problem since the furnance and AC were replaced. Well worth paying for the warranty service. Thank you Keil. Will continue to recommend your services to others.

Went beyond normal semi-annual inspection, explaining things to remember.

Yoon, our service technician, was very thorough in replacing our expansion tank and doing the annual cleaning of our furnace. He checked all heat flow paths as well to ensure proper heat distribution. Keil pricing is fair for the professional level of service provided.

Excellent service call, as usual, be it A/C, Furnace or Generator service.

Thank God! Keil held on to an estimate from 2 years ago and when I desperately needed a new ac system, they were able to start and complete the job the day after I called!! I couldn’t believe my luck. Then the guys stayed and finished after a long hot day in the attic. They were clean, courteous and took the time to explain everything. I’m so grateful I called both two years ago and two days ago!!

John explains the correction to the problem very well. Thanks John!!

Asanti was great

John was very personable and knowledgeable. He was very helpful.

Very thorough service

We replaced our heating and AC units 5 years ago and have had no problems. Having the warranty makes it so much more comforting to know if anything goes wrong, Keil is just a phone call away. We always recommend their service to others. Thank you Keil Heating & AC.

Showed up on time and went right to work. He took extra precautions, gloves, mask etc. When he was done he wiped down everything with a cholorox wipe ie. the furnace, basement door handles, iPad, pen and the credit card.

The crew from Keil always do a great job and are always courteous and friendly.

H. Yang was right on time, quick and efficient and explained everything when he left!
