I would not - carpet cleaning - either "shampooing" - wet processs, or vacuum-based, should not put significant dust into the air as long as their vacuum filters are in place. Duct cleaning commonly does and if they make a connection mistake sometimes has the potential for a dustcloud being generated by mistake - so if your ducts actually need cleaning (which is a rare thing), have that done first. Ditto to a good dusting or compressed air blowing off of all molding and elevated surfaces and shelves and such fi they need it, before the carpet cleaning.


BTW - if your furnace/air handler filters are working right your supply ducts should not be real crudded up and the return duct dirt should not be able to migrate to the supply ducts. Also, except if the ducts are banged or moved around during repairs, or you have a good sized earthquake or major air pressure change event like a near-miss tornado, the dust in the ducts generally stays put and does not come out into the house - the ducts just act as a filter of sorts to filter out the dust and dirt as the air passes by.


[Note - some exceptions for people with severe asthmatic or other respiratory or allergy issues, where every bit of airborne dust can be an issue. Ditto if you have mold growing on the dust in the ducts because of excessive humidity in the incoming air, or crudded up/excessively wet A/C coil or short-cycling A/C]


Plus if your ducts are flexible, rather than rigid metal, cleaning them presents a significant risk of damaging them.
