Very quick and efficient estimate for duct cleaning via FaceTime. Eric and Leo were great. Both were super courteous and very efficient. Eric took time to share his thoughts on some issues we pointed out before he started, which he resolved. Very good experience today.

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!
