Bill T recently arrived at our home to clean our air ducts which, to our knowledge, had never been cleaned-28 yrs.. He did a fantastic job, he was very professional during the entire time in our home. He explained everything that he was doing, took before and after photos of the ducts themselves, cleaned the furnace, checked the dryer vent, etc. He had to go in ad out to the truck several times and each time he re-entered the house he put shoe covers on to protect our hardwood floors and carpeting. He laid packing blankets on the floor before bringing in hoses, etc. I will highly recommend them. Thank you Bill!
