The technician for our residence was Byron. He arrived at our house around 8;45 and presented his company very well. We went through the process and then went to each level noting the registers and the cold air returns. He started on the top floor first - putting blankets down before bringing in any of the equipment. He also put safety corner protectors on corners where his cords and hoses would contact our base molding and drywall preventing any kind of damages to our personal home. (Greatly appreciated)! He began the cleaning process from the top floor to the lower level each time explaining to us what he saw and if there was anything out of the ordinary. He was very professional and courteous. When he completed the cleaning process, he cleaned up everything not leaving any trash behind. It was a positive experience with Byron and I will definitely refer this company to our neighbors and friends. Thank you for your service!!
