I would never do business with a company this dishonest again. I was lied to by a technician who cleaned my air ducts that it was guaranteed. When he did a shabby job and ceiling around vents were dirty very soon after cleaning I contacted Blackmon mooring and they would not even return my call. I reported them to BBB Lubbock with no response. I would suggest no one do any business with a company this dishonest and report them to BBB so it will be on record. I only wanted the 10 ducts for $199 but technician said it would not be guaranteed unless I did all ducts so I did. I paid $350. Nothing but lies.
