When we moved into our home, there was wall-to-wall carpeting in every room.
The first thing my husband and I had on our list of two dues, was removed the wall-to-wall carpeting and every room but the guest room.
The guests that we got to our home, was usually our parents. His parents and 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 living room, and two air vents in the dining room. I couldn’t understand why they were air vents if there was no ductwork in the house. My husband got a chuckle out of it, but I didn’t see anything funny about it. I had air vents in this beautiful hardwood flooring we had uncovered, and they were necessary. All the air vents were doing was taking away from the beauty of my hardwood. After calling the HVAC company, I called the flooring center. I wanted to see if they could cover that part of the flooring were the air vent was, and make it look like it belonged in that area. The HVAC company showed up before the flooring company. They told us this house originally had ductwork, but when the owners put in ductless HVAC, they only had the ductwork removed and 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, but it was going to be a little expensive. Now I understood why they just closed off the air vents and left the covers there.
