4th of July, heat index 107 and our air conditioning developed problems, called Charlie's to get on the list. Expected that they were probably covered up due to the heat. Was extremely surprised to get a call from Shawn saying he could be there in an hour. He found the problem quickly and had us back in the comfort zone. Have always had great service from Charlie's and this just reinforces that.
We are so happy that Shawn could take care of you on the 4th! We really appreciate you taking the time to let us know how much it means to you. Thank you for being a customer, and give us a call any time!
