We've been working with Allstar Heating and Air Conditioning and they are a great group of workers! We had our A/C installed by them but most recently we called them and had them come by to take a look at our A/C unit because it was acting a bit faulty. They came by in the time they allotted for me and opened the unit up to see what was wrong. They were in and out in less than an hour and everything is working great now except, I have been having some issues with the keypad so I will be calling them up to see what they can do about that. But overall great customer service and will be working with them in the future.
