They were to be out around 8:30am Friday. But called Thursday late afternoon. Said they are on a job now. That won't get finished. So they will finish that in the morning. Be by us between 11am and 1pm. By 11:30am they came out. By 2:30pm central air was installed. The men were friendly. Got right down to work. Everything was installed properly. Dh inspected the work. They said if there is a problem. Call them. Someone will come out 24/7 if need be. By late evening. House was feeling pretty cool. This unit is a little quieter than the old one. In ways I am glad dh talked us into going into hock for this. We were going to need it eventually.
