Problems with the indoor air can come from the ductwork.
The ductwork is a closed network, but it can be infiltrated by terrible service plus vermin.
A client contacted myself and others last week. She had a problem with mice inside of his ductwork. The client was frantic, because he did not want droppings from the mice to end up in his home. I commanded sealing the duct work plus sanitizing all of the surfaces. This is a service that the people I was with and I offer to all of our Heating plus Air Conditioning patrons. The guy agreed to the service appointment plus the people I was with and I set his up for a few mornings later. I was on the job with several additional crew members. The people I was with and I went to the attic where the ductwork was Loki. I tried to find a way into the back of the attic area, but it was impossible. I searched the ductwork up front plus I saw some visible signs of mice. After that, I recommended that the people I was with and I put a special chemical inside of the ductwork that seals all of the holes automatically. The glue particles stick to the surfaces inside of the Heating plus Air Conditioning method plus the ductwork. This creates a barrier of protection plus fills in all of the cracks plus crevices. After the glue has time to dry, the people I was with and I clean all of the surfaces with a special sanitizing solution. It gets rid of 99.9% of all the germs, bacteria, viruses, mold, plus mildew. It is one of the most advanced systems on the market. The people I was with and I are one of the only companies offering this glue polymer technology.
