Ductwork cleaning yearly due to projects

They say every 5 years you should get your ductwork cleaned.

After that amount of time the hair, dust and bugs build up to the point it needs to be removed.

I spring for ductwork cleaning yearly. My reasoning is that I am always doing projects in my house. When I first moved in I sanded my wood walls and painted them. I also scrapped all my popcorn ceilings and painted them. The dust from those projects got into my ductwork. I didn’t want it to affect my indoor air quality and productivity of my heating and cooling system. So I got the ductwork cleaned. The next year I sanded all my wood doors and painted them. I also tore down some drywall and mud in my bathroom. I had to get the HVAC ducts washed again after those projects. I am going to get ductwork cleaned this year since I just gutted my kitchen. The dust flying around is insane. I am removing drywall, smashing cabinets and sanding like crazy. The HVAC is on the whole time and sucking up the dust in the ductwork. I don’t want to leave all that debris in there. Not only is it not good for my health, but it would be impossible to keep my home clean. The dust would fly out of the ductwork and make the surfaces dirty. I also have long hair and I have a cat. Removing our hair from the HVAC equipment is never a bad idea. Ductwork cleaning isn’t all that much money too. The whole appointment may take an hour.
