I just had a new HVAC system installed and the contractor installed in on a pounding raining stormy day. I am thinking that was a bad decision on his part. Now my home has a musty smell and air seems drier than when I had my older system. Would you expect air quality problems because of this installation. Thinking I should have my air quality tested. Also when I read on line it says 78 should be a comfortable degree I need to leave mine on 72 to get some air on second floor, does this seem unreasonable. Should contractor adjust something on system to get more flow upstairs. Any ideas on how to keep air temperature more even throughout the house. Thank you, Debbie

I think you may need to have your ducts tested and resealed. Leaky ducts can allow musty air from a basement or else where in, and results in low output in parts of the house. Causing warm/cool spots.
