My husband, Paul, called Duct Diagnostics after getting a referral from a friend, and is he glad he did. From the nice office secretary, to the owner, Ralph, (who personally came out to our home for the estimate)to the two technicians who serviced the duct work, Jim and Scott, from"soup to nuts" all was great. Everybody was professional and pleasant to deal with. I highly recommend them!

The crew (Dan, Leo & John) showed-up right on time, explained what was involved with cleaning the ducts, walked through the house with us to make sure they knew where all the supply & return register were located and went to work. They put down drop cloths, covered all furniture near their work area and wore booties when in the house. The entire process was dust free! They were friendly & courteous. They showed us before and after photos of the ducts…BIG difference! Well worth the money! It’s great to work with a company that cares about their workmanship and their customers. We highly recommend them!
