Universal Air & Heat review: a/c duct cleaning - platinum package

Ordered the Platinum Package. Technician hooked up vacuum to an air supplier but would not clean out each air duct, as advertised. Would not clean the duct covers as advertised. Would not honor the senior citizen discount. Said they had right to substitute another service. Free inspection said to have found severe mold in air handlers. Showed alleged photo. Would not send me the photo as promised. Company followup tech could find no mold in air handlers. Tech said to apply Poly Propylene sealer. Followup tech never heard of the product and could not find it to apply. Charged $866 and hour. Very very expensive poor service. If you still use them, recommend signing paper copies only. To sign an IPAD may mean your signature may be moved to other documents you may not have seen. I signed one document and later found it present on two other documents via some kind of electronic transfer.
