My warranty company (American Home Shield) sent them out to check out an AC problem we were having. Our technician was Felipe and he was AWESOME!!! It turned out we needed a new capacitor. He replaced it and did a very thorough check of the other components and found everything else checked out ok. He even gave us an education lesson on how it all works. We were very impressed with him and are thinking of using them as our normal yearly service company. Very happy customer.
