We had Brian, Edin and Derlin come to install our new ductless air conditioning system. Lisa from the office was very pleasant to deal with setting up the appointments and calling 1/2 hour before the team was to arrive. We also received emails with their pictures included introducing the team and saying they were on their way. Everyone was very courteous and neat in the installation. Marc was very courteous and professional from the first appointment and coming by to check progress of job at beginning, middle and end. He also called a few times upon completion to see if we were completely satisfied! We will certainly recommend Gold Star to all family and friends.
