Back in May we need our AC unit replaced in our house. Two years earlier we had replaced the furnace so we only needed a A/C unit. We got two other estimates but the Sherman’s price was a little better than the others and given they were in town(Cary) we went with them. Now that it is September and the unit has run all summer I can say that they did a great job. It was a one day job that went well. I know it took longer than they expected but they stayed with the original estimate and even add a cold air return at no charge. The outside unit they recommended was also much quieter than our old one and because it is close to our deck made the use of our deck much more pleasant.
