I Called this company Just Clean My Air Inc. and they said they were licensed and insured. I asked what their licence number was and they provided it.I checked their website Justcleanmyair.com and there was no license listed. After checking with the state of Florida I discovered it was an expired plumbing license. I called Just Clean My Air Inc to inquire about their air duct cleaning service.Why would they give me an expired plumbing license. After checking further with the State of Florida I discovered they have no contractor license to do air conditioning work and an unlicensed Duct Cleaning company may not even remove a screw let alone a vent cover. I am very upset a company can pass themselves off as doing legal contractor services (in this case messing around with air ducts and AC systems)and is allowed to keep doing business. I recomend anyone considering air duct cleaning to check their license at the DBPR (Department of Business & Professional Regulation)for your protection.
