There is very little government oversight of the duct cleaning industry. You see ads in the newspaper hear them on the radio of companies offering whatever price to clean your ducts. Your rule of thumb is Caveat Emptor.

Insist on NADCA certification of both the company you are dealing with and the individual tech that performs the work. .You must also require that all work is performed to NADCA standards, and that they have it in writing. You should also insist on EPA certification.

If these requirements are not met you will invariably end up not having your system cleaned, and settle for paying for a less filthy system. You will also likely end up with a low suction application resulting in your system cross contaminated to some degree.

Generally air duct cleaning companies do not properly clean your furnace let alone touch your evaporator coil. Often they do not even have the equipment to do so. This means you have paid money to breathe dirty air and guarantee that your air conditioning system will run less efficiently and break down sooner than it should.

If you find a company that actually will be cleaning your coil, ask them what they would do if a leak occurs? Cleaning the coil can be a delicate operation because the AC lines are often old or fragile. If not properly done, lines can be damaged –and result in a hazardous refrigerant leak into your home. Do they know how to “pump down” an AC unit? If they say they would call another company to deal with the problem…it’s too late. If a leak occurs, all of the refrigerant will leak out of the system in as little as an hour.

All Monster Vac Technicians are NADCA and EPA certified, and licensed to handle and recover refrigerants according to EPA regulations. Demand that your techs performing the job are both NADCA and EPA certified. (Back to top of page)
