I searched Google for 5 star reviews. Darnold & Lyons were one of the companies with 5 stars. But it was the reviews customers wrote. I can understand why.  The service man was named John and he came in and immediately said I know exactly whats wrong. Said it was an easy fix. I was so relieved. He made me feel comfortable and he was very confident. He had my problem fixed in about 30 minutes. I have just moved into my place and also had my heating and cooling system maintanced by another service under the recommendation from a friend. It was a big waste of my time and money. I would use Darnold & Lyons for any and all services and maintenance if needed. I just also want to take the time to thank John and just to let him know how I am so grateful. I’m sure they have many good service men but I’m going to tell you John was perfect and knew exactly what he was doing. I recommend Darnold & Lyons highly.
