“Well the office staff was very patient with me making several calls to them to find out what time Ferrell would be here because I had a doctors appointment so a big shout out to them and Ferrell who comes out and checks my heating and air unit, Every six months is awesome. Great guy! He really helped me out today so that I could get on my way to my doctors appointment so thank you Farrell.”
