Lately I have noticed a lot of problems with excess dust and dirt in the house. I clean all of the surfaces in the living room including the television and the coffee table and 2 hours later there is still dust and dirt that accumulates on the surfaces. I thought that I was using a poorly made dusting spray, so I bought something that was more expensive and I used a special cloth. I still had the same problem. Since the indoor air quality wasn’t what I wanted, I talked to my husband about calling a Lowell heating and AC company that specializes in indoor air solutions. The Lowell HVAC company was happy to schedule a free indoor air quality check with my husband and I. Both of us had to be home at the time in order to qualify for the free air quality check. When the representative from the Lowell, Massachusetts, heating company arrived, one of the first things that he did was check all of the ductwork. He looked in the attic to make sure that all of the ductwork was sealed up properly. The technician told us that was the number one problem to cause this type of issue. There were plenty of places in the ductwork where the ducting wasn’t even connected. The technician said we should start with those repairs and see if that helps the problem. It took nearly 2 hours for the service technician to repair all of the ducting issues in the attic. It’s been a few days and I think that actually helped the problems quite a bit.
