It wasn't more than a couple of hours from the time I called in my problem, till Rob was here to fix it. Rob was very up beat, even though it was a very hot and humid day and he got us running smoothly again very quickly. Our older (10 Yrs) system was low on refrigerant as I suspected it would be, and he gave us good advice and options for that day and down the road. We have used Sandpiper two other times and the story is always the same. Great service and extremely fair cost for such professionalism! We recommend them to everyone who asks!
