AC stopped cooling 10:00 at night. Called Alliance next morning and service tech was here a little over an hour on 4th of July at that, not to mention 100 degrees weather. I would say exceptional customer service. Office has very friendly staff and accommodating . John was very knowledgeable and had fixed in an hour. Will have my future business. And happy to refer out. Thank you Alliance. Nancy and Terry.
