Back before the pandemic, they had actually never cleaned the air ducts in our building before, but then once the pandemic started up plus all the people was freaking out about the indoor air quality, the landlords decided that they were going to do something to make sure that the air ducts in our office were squeaky clean. I really was pretty surprised that they decided to go to any trouble, since I had never entirely thought that the owners of the building cared much about the renters who were renting their spaces much at all. I suppose I was wrong about that, though, because the owners decided to call up the local commercial Heating & A/C supplier that they have their contract with plus get down to business. It turns out that while the office was closed down for many weeks, the Heating & A/C supplier got entirely tied up upgrading all of the heating plus cooling device in the building. Every one of us got an certainly new gas furnace plan plus a new central air conditioner unit that would be able to handle many floors. Not only that, however the commercial Heating & A/C supplier ended up installing all new ductwork, air registers, plus heating plus cooling vents throughout the building. To top it all off, they installed UV light air cleaners to run along with the new heating plus cooling system. It was entirely a long time coming, however I suppose they finally did the right thing as far as the heating, cooling, plus ventilation goes in our building. The indoor air quality in the office is the best that it has ever been.
