I knew there must be some concerns with the HVAC duct in my home, because there were hot and cold spots all over the locale.
In the living room there was fantastic airflow at the south side of the room but on the north side of the room there was no air flow at all.
In the home office we had little air flow too. I decided to contact a contractor that specializes in HVAC duct concerns and solutions. The commercial and residential heating and A/C service and replacement contractor sent a specialist that was skilled and prepared to deal with the HVAC duct concerns. He went into the attic and crawled around for nearly an hour. He came out later with information that I did not want to hear. The kid took a bunch of pictures of the HVAC duct. The HVAC duct concerns were a huge mess. There were parts of the HVAC duct that were completely falling apart and there were some parts of the HVAC duct that had holes and needed to be sealed. The specialist felt that the entire system and network of HVAC ducts needed to be upgraded including all of the sheet metal. He offered me a price for all of the fabrication and replacement work and told me to call them when I was ready to get the system upgraded. I believe that I will wait until I am ready to upgrade the heating and A/C system as well. It does not make much sense to do both tasks at a separate time when they should be done together.
