I was charged over $2,000 to have my ducts sealed. I was told it would minimize the dust, and reduce my electrical bill. Well, almost six months later, the dust has gotten worse, and no drop in electrical bill. My allergies have gotten worse (remaining indoors with windows shut). The procedure itself took maybe 30 minutes, and the guy spent half his time on the phone. I am calling for a third party inspection to see what work was actually done, and file a claim against the company.
