Sal & Ashley were the techs who cleaned out our ducts. They were friendly, well dressed, clean cut, and behaved in a professional manner. They quickly completed their job and cleaned up after themselves. My husband was sitting down to rest and watching Sal clean the grate the goes over the air return. My husband told him to leave the water running so that he (my husband) could spray the grass clippings off the side walk. Instead Sal volunteered to do the job. I got him a broom so he could sweep the grass then he sprayed the last of it off the walk. Ashley also helped with another small task. Both of them answered questions and were extremely polite. It was a pleasure to have them do this job for us.
