How do I explain what is happening to the furnace?

I couldn’t think of the right words to tell the HVAC company what was going on with the furnace.

Everything I came up with came out sounding like I was stupid.

I had plenty of heat, and the airflow was phenomenal. The only thing I didn’t like was how there was a puff of dust coming out of the air duct when the furnace first started. I was sure there had to be a problem. My daughter thought we might have a dragon in the air duct, and my response was to roll my eyes. She ran to her father and told him mommy was being rude. He was laughing when he came into the kitchen to chastise me. I told him there was dust coming out of the air vent every time the furnace turned on. He asked if I had the records for the HVAC system. That would tell us when we last had the ductwork cleaned. I thought the paperwork was in the basement cupboard in the furnace room. He ran down the steps to look for the paperwork. He said he was sure he had found the problem. It had been nearly four years since the ductwork had been cleaned. He called the HVAC company to have the ductwork cleaned. If the dust was still coming out afterward, we had a more difficult problem to deal with. I rolled my eyes when I saw my daughter watching me. She patted my hand and told me I was a good girl for not being childish and rolling my eyes at her daddy.
