Abandoned return air vents


An HVAC contractor installed three new cold air returns. The previous existing ones are no longer connected to the furnace. I want to install blanking plates but my wife wants to leave things as they are. I think this is a mistake since dust from the crawl space will come up and enter the rooms through the grilles, all wall mounted.

Am I correct? Need some ammunition!

Seal them. Or have them reconnected. Leaving them open is one of the worse things you can do.

Consider the bugs that now have an open door to your home.
