From our own experience, that is a big "NO". You get what you pay for.
Be very wary of "Blow-N-Go" air duct cleaning companies. Many of these companies are not licensed, certified or insured. They use subcontractors, arrive in their personal vehicles and use small shop-type vacuums The risk of using a "too good to be true" duct cleaner can be disastrous.
Indoor Air Quality: The Environmental Protection Agency (EPA) performed studies and have found improper duct cleaning can pollute the indoor air many more times than if you had left the ducts alone.
Insurance: Without liability and workers' compensation insurance, you will be responsible if someone gets hurt in your home.
Carpet Cleaners: The equipment traditional used for carpet cleaning is a wet process. Ductwork cleaning is a dry process. No licensing is required for carpet cleaning; wouldn't you prefer to have a licensed contractor access your AC system?

Every home and business is different. Many factors influence the hygiene levels of your HVAC duct system including the type and frequency and proper maintenance of filter maintenance, A/C component maintenance frequency (evaporator coils, blower motors, pan treatments, etc), duct leakage, humidity levels and structure location, to name a few. Let us inspect!
The frequency of cleaning depends on many factors within the building. These factors are numerous and can include:
Fiberglass and hogshair filters are the lowest efficiency, retail filters available.
Check your filter by holding it up to the daylight - if you can see through it, the smallest particles can pass through.
There are many types of good filters available commercially; the higher the MERV rating, the more efficient the filter.
The EPA has air filter advice - https://www.epa.gov/sites/default/files/2020-06/documents/2019.11_tech_bulletin_filtration.pdf
Yes, as you change the oil in your car every 3,000 miles or so, your air conditioning system needs to be checked out regularly.
