Oil Boiler or Radiator Heating System - Repair

Our boiler stopped working. When I consulted Angis list Kevin was the first to response and by his reviews I chose him. He was quick to answer and quick to come to our house. Price is very fair and I will definitely keep using him going forward with our boiler issues

Very professional. The service was outstanding. Quick diagnosis and simple fix. Others wanted to replace my entire system for many thousands. I would call them anytime for any heating or cooling issues.

After a number of calls to various companies, I reached out to home advisor looking for help ASAP with my central air that wasn't working on a Sunday when it was a 95 degree day. Within 2 minutes my phone rang and it was Kevin from KN heating and cooling. Kevin was at my house with 15 minutes. Not only did he figure out what was wrong and fix it, he found a number of other issues that need to be taken care of. Kevin was amazing and even walked me through what he was doing and explained everything to me. Not only do I recommend him, he's will now be my go to for service on my boiler and central air. Outstanding service and extremely reasonable! Wish I had him do the initial install!

My a/c circuit breaker kept tripping upon start-up of the unit. I read the positive reviews about KN, so I requested a quote and Kevin responded with a text within an hour. He was even able to come the same day and spent 2 hours to thoroughly inspect and test the various components of the system (including the connector in my attic), and replace the hard start. Kevin was very professional and thoroughly explained how the system functions and what he was doing each step of the way, which I really appreciated. I would highly recommend Kevin for your HVAC needs!

My furnace is about 20- 30 yrs old, steam for radiators and he knew exactly what had to be done and had the materials to fix it. New sight glass fitted and put in, etc. Nothing like skill generated from the experience of having done it. Had the equipment and moved forward. Put heat back in house, fixed water heater, and all is good. Will call him again. R
