My apartment is so old as well as as such I had a absolutely untypical issue going on with the ductwork of my central heating as well as cooling system unit. In short as well as to the point, my ductwork was falling apart! It was a major issue as well as it cost me numerous thousand dollars to fix. I never imagined that one day I would have this kind of an issue with the ductwork of my central heating as well as cooling system unit. I actually never had heard about the ductwork falling apart before. But it was when the local heating as well as air conditioner specialist from my local heating as well as air conditioner business told me that this was the major issue with the air flow of my central heating as well as cooling unit that I found out. I was originally thinking that maybe my ductwork was just dirty as well as needed to be cleaned. This was sadly not the case, then and what was in store was a major investment that cost me almost just as much as having to buy a brand new as well as totally new central heating as well as cooling system unit. At least now though I do have brand new ductwork for my central heating as well as cooling system unit. It was a major job as well as took much construction to get it going all together. I took them an entire 8 hour work day to replace the ductwork that had fallen apart to my central heating as well as cooling system!
