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!"

"Ali promptly replied to my initial email, made an appointment for the following day, and showed up promptly at the agreed time.  The system actually started working again later the same day that I called and the problem was likely restricted airflow to the air handler.  He checked out the system, confirmed that refrigerant levels were good, and the coil was clean.  He refused to charge for any maintenance, as he said he didn't really do anything.  he also checked out my Wi-Fi thermostat wiring and confirmed that it was correctly installed and that the unit itself was probably defective.  He gets an "A" on all accounts and I would highly recommend him!
