I feel fortunate to have done my research and come across to Dave's Ducts. They are professional and prompt in the delivery of their services. From the customer service perspective, I found them very patient and going the extra mile, so to speak. We purchased a 2-day service that included Aeroseal Duct Sealing and Duct Cleaning packages - very happy with the results. The company provides before and after pictures, metered readings of the volumes of air throughput, etc. Overall, I found them to be exceptional from the point of sale and through to carrying out the work.
