My experience with Greer's Banner Air has been very favorable for the last ten years. This last New Year's Eve weekend, I had a problem with my furnace. And they sent someone out on holiday to fix it. I also appreciate their annual maintenance contract. I continually use Greer's Banner Air because of the continual good service and their promptness. It doesn't take them two or three weeks to get on their schedule either. It's easy to make an appointment. And their staff helps. What's nice is I have the same repairman every time. He's been fixing my cooling for ten years. His name is Joe. I would tell an interested party that they are efficient. Their cost is at a good level. Even their office billing is efficient. Greer's Banner Air are professional and friendly. And they're very respectful in my home. I would and I have recommended Greer's Banner Air to my family and friends.
