I recently decided to take advantage of rising condo prices plus sell my house. I am hoping to sell now when prices are high, continue renting for a while, plus then buy again when the prices fall again, as they invariably will. Well, I have 2 aged window cooling system units that do not rest in windows at my house. They were installed into the exterior walls of the home multiple years ago, plus they have reMained there, unused, even though the home has had central heating plus cooling for about multiple decades now. I never saw the need to get rid of the window cooling system units, plus in fact, they periodically came in handy when I needed to get the Heating, Ventilation, plus A/C system diagnosed or it was 110 degrees outside plus the common cooling system needed a little help. But the realtor says I must get rid of them because it makes purchasers wonder if the central heating plus cooling system is inadequate or unreliable. Since neither is true, I think I need to say goodbye to my window air conditioners, plus that means saying goodbye to the holes in the walls, as well. I never really wanted to bother with the cooling system units because I didn’t want to have to bother with the resultant holes, however I think I just have to at this point. I am trying to decide if I should just fill them in with more wall material or if I should turn them into windows. They are sited really high on the walls, so windows might look a bit odd. In any event, I will miss the little window air conditioners.
