Teach your drivers to stay off their phones while driving. Cals2 license plate was unaware of what was going on around him he was so engrossed. Couldnt be bothered to signal when turning either. What the hell is wrong with you?

Just had a great experience with Ernie and George. They just replaced our furnace because it was on it's last legs. He was able to get to us right away because my Mom was having a problem with the cold. Was very quick replacing it and was great with the price especially when everyone else we called were much higher on their price with a much longer time line to replace it with. Couldn't have gone any smoother. I would highly recommend Ernie and Cal's they're very good and caring and tells with his quality of work.
