When you move into an old house, don’t be surprised if there are no vents at all. Central air conditioning system is always my preferred systems of air conditioning system. Our house has no vents of any kind. When the original owner built this house, baseboard heating systems were all the rage. There was no need for a furnace, because the baseboard heating systems could heat each room individually, this would allow you to customize the temperature to your desire. However, with no vents for the furnace, that meant you have no vents for central air conditioning system either, installing vents in our house would involve a lot of cutting holes for vents and ducts. I am not that interested in central air conditioning system that I will not consider other options. Unfortunately, the windows are not realistic for a window air conditioning, and window air conditioners aren’t as efficient or powerful. That left me with few options. I could purchase a portable air conditioner, which I could wheel around the house anytime I wanted to be cool. Since that didn’t appeal to me, I also could choose to purchase ductless mini-split air conditioner. They work well, require little upgrade and can also be used as heating systems and air cleaners. These air conditioners are also placed high on a wall plus take up very little space. They are also sleek and attractive while providing a powerful cooling effect for your house. When you find yourself in an old condo with no furnace or vents, consider ductless mini-split air conditioners. They are pretty “cool.”
