Q:Β I had a new air conditioning system installed recently, partly because we had way too much dust in our house all the time. The AC people told me that I had only one intake for the HVAC system, and I needed two of them. But after they added another one, the dust got even worse in the house than it was before. So what do I do now?
A:Β You need to have a pressure test done on your entire HVAC system to see whatβs wrong. Itβs possible that you have a leak somewhere in your duct system that is taking in dust from the attic and then blowing it into the rest of the house. Ask the people who did your AC installation to do the test. They may tell you that you have to pay for it. Thatβs OK; just tell them that you will pay, but that if they find a leak, they need to fix it because they should have done it when installing the new system. If they canβt find the leak, they can still blow something called Aeroseal into your ducts that can seal small, hard-to-find leaks from the inside out.
