Windows can provide the rooms in your home with an efficient and affordable form of ventilation, especially if you don’t experience extreme temperatures in the winter, summer, or throughout the seasons. But windows certainly aren’t the only way to keep your home ventilated. So if you happen to have rooms in your home that don’t feature windows, such as bathrooms or basement and attic rooms, don’t fret. Here are some options that will help you to keep every room in your home properly ventilated even if there are no windows to speak of.
For one thing, you could install windows in exterior walls, supposing the room itself shares walls with the exterior of your home. For basements, this may require you to dig a hole and install a window well, the measurements of which will likely be a matter of city building codes. But the truth is that installing windows can be an extremely costly process. And depending on how your home is situated on the property and where the windows would go, they might not end up providing the cross-breeze needed for adequate ventilation anyway. There are other options to explore, though.
If you have an exterior wall at your disposal, for example, you could simply install vents equipped with fans to suck in hot air and expel it from your interior living space. Or you could just put in a ductless heat/AC unit. Such units will require you to cut a hole in the wall for installation, but they will then be sealed tightly in place (so as not to let air pass in and out around them). From there all you have to do is select heat or AC settings, depending on the weather and the outdoor temperature, and the unit should both adjust the temperature in your room and vent stale air outside.
But of course, you might not have an exterior wall to work with. While it is not advisable to place a ductless unit where it will vent into another part of your home, that doesn’t mean you can’t find options that will work. If you want to go low-tech, install an old-school transom window over the door to the room, along with a ceiling fan. Periodically, crack the window and turn on the fan. This will circulate air and help to ventilate the room. Or you could install a vent fan over the door if you prefer just one piece of equipment. This is assuming you can’t simply open the door for some reason (perhaps because you’re hosting guests who prize their privacy or you want to keep pets out of the room).
You can also install vent/fan options in the ceiling, and this is common in bathrooms. These fans will be ducted to vent outdoors, even if they’re interior rooms, but they don’t tend to be very powerful, so they might not be the ideal choice for larger rooms. And there’s always the option to extend your current HVAC system so that it reaches the unventilated room in question, although HVAC repair and installation at this level can certainly cost you a pretty penny.
Whatever you choose to do, it is important to understand the crucial role that ventilation plays in your home. Without it, the air in a room can become stale, polluted, and harmful to your health. So if you have a room with no windows, consider the many options available where ventilation is concerned.
