I've been calling RL Lyon for last few years for AC/heating issues and they've saved the day every time. Two days ago my A/C went out during the hot streak and they came out and tried to fix it in less than a few hours! Unfortunately the unit was bad, and they got me a new unit and installed it the very next day. I am very grateful for their service!

We just recently moved to Morris and I wasnt familiar with our built in humidifier. I google heating and cooling places near me. After reading some great reviews I gave R L Lyons a call. Im so glad I did! What exceptional friendly informative employees! He showed me how to work our new system and answered all probably silly questions I had. Im so happy I called them and they have a new long time customer because of such great service.

I was very impressed with this company from the moment that I called them. They came for a cleaning within 2 days of calling(it was not a rush)and the technician Jay was wonderful. He explained everything he was doing and was very informative. We will definitely be using this company in the future!!
