After reviewing many ads, we saw the many good reviews for Capps and decided to give them a try. Paul arrived and had a look around then explained how duct cleaning worked and what he was going to do. He explained everything so well, we were both shocked as we did not expect this. He was very courteous, removing his shoes each time he entered the house and was always making sure nothing was in the way that could cause damage to the house. When the cleaning was done he showed us the difference in the pressure from the cold air returns and even took the time to clean the vent of dirt marks! We were very impressed and would definitley recommend Capps to anyone looking to improve their ventilation. Very knowledgeable! Thanks for your hard work!
