Sani arrived shortly after 8:00 a.m. to begin a very big task -- cleaning the vents in our three story home!! Sani was incredibly professional and worked hard all day to ensure that our vents and main line were well cleaned. He had to work for a couple of hours in our crawl space to cut into the main line, clean the line and close the opening. He did so competently and without complaint. Sani is a credit to your company and should we need your services again we would request that Sani be our technician.
