Ryan showed up in person to give me a quote which automatically put him ahead of the competition. He was better priced than his competitors and he did an amazing job. Our new home we bought had 4 dogs in it prior to us, and the owners before them also had 4 animals. We noticed an immediate relief on our allergies when he was done. He was friendly, professional and knowledgeable. If you’re looking for a reasonably priced duct cleaning, reach out to Demmith! You’ll get your money’s worth!

They did a fantastic job on our ductwork cleaning! Showing before and after pictures, the difference is unbelievable! No mess at all in the house. They also cleaned the chimney on the workshop and installed a weather vain for me while they were up there putting on a new chimney cap. Father and son business getting started, working hard and doing a great job!
