Is it beneficial to clean air ducts regularly?

On the last service call, my HVAC technician recommended that I clean my air ducts.

I was caught off guard by his recommendation because I have had many HVAC units over the years, and I have never been told to have my air ducts cleaned.

Based on what my HVAC technician said, cleaning the air ducts can improve the air quality in my home. In addition, it would also eliminate or reduce the buildup of mold, dust, debris, insect carcasses, and more. Furthermore, he mentioned that cleaning the air ducts can improve the efficiency of the HVAC unit as well as extend the lifespan of it. Lastly, if there are any weird odors inside your home that are caused from the HVAC unit, then cleaning the air ducts could eliminate them. As you can tell, my HVAC technician provided a ton of benefits to cleaning my air ducts and to be honest, I am surprised that no other HVAC provider has ever recommended this service to me. I am glad that my HVAC technician brought this to my attention because having clean indoor air quality is important to me. And surprisingly, the cost of performing this service is quite affordable. My HVAC technician also performs this service and he quoted me less than $400 to clean my air ducts. He provided this quote a few weeks ago and though I have not yet agreed to the cleaning, it is something that I am considering. I would like my indoor air quality to be at its cleanest and having my HVAC air ducts cleaned might just be the best way to accomplish that.
