Why are there air vents if there is no HVAC duct?

When we moved into our home, there was wall-to-wall carpeting in every room. The first thing my hubby plus I had on our list of two dues, was removed the wall-to-wall carpeting plus every room however the guest room. The guests that we got to our home, was usually our parents. His parents plus mine both liked wall-to-wall carpeting. When we began ripping the carpeting out of the other rooms, I was surprised to see air vents in the floors. There were two air vents in the main kitchen, plus two air vents in the kitchen. I couldn’t understand why they were air vents if there was no HVAC duct in the house. My hubby got a chuckle out of it, but I did not see anything funny about it. I had air vents in this beautiful hardwood flooring we had uncovered, plus they were necessary, then all the air vents were doing was taking away from the beauty of my hardwood. After calling the Heating plus Air Conditioning company, I called the flooring center. I wanted to see if they could cover that part of the flooring were the air vent was, plus make it look like it belonged in that area. The Heating plus Air Conditioning company showed up before the flooring company. They told us this cabin originally had HVAC duct, however when the owners put in ductless Heating plus Air Conditioning, they only had the HVAC duct removed plus closed off the air vents. This made me feel little better, but I still had to get rid of the air vents. The people from the flooring company assured me they could make it look just like the rest of the flooring, however it was going to be a little costly. Now I understood why they just closed off the air vents plus left the covers there.
