Why Do You Need Ventilation In A Garage?  

Ventilation In A Garage

Ventilation is necessary for every room in the house, not only for the garage. With it, we can create fresh air circulation in a very short time, cool down the garage, remove fumes and odors, and reduce condensation. Here is what good ventilation can do for a garage:

Cool Down a Hot Garage

Ventilation is most often used to cool down a hot garage. If we have a garage with no windows, it can become unbearably hot inside during the summer when the temperatures outside are high. Therefore, the only way to use the garage for work is to ventilate it. Otherwise, the high humidity inside will make you sweat, which is not pleasant at all. Having a window in your garage allows you to ventilate it and create a pleasant atmosphere during the hot summer days.

To Have Air Circulation

The fresh air is also an advantage of ventilation. New air that comes in helps you remove moisture on your skin. This helps the body to cool down. Also, fresh air is healthier for the body, and at the same time, the humidity in the air decreases with it. At the same time, the human brain works better with air circulation. The simplest way to create air circulation is through ventilation.

To Remove Fumes and Odors

As the garage is a closed space, fumes and odors accumulate. This is primarily for several reasons. Every time you use your car and park it in your garage, exhaust fumes are created. Also, you’re adding an unpleasant smell when you paint, sawing wood, or some other thing in your garage. Therefore, if you don’t have good ventilation in your garage, it will be hard to remove fumes and odors from it.

7 Ways To Vent A Garage With No Windows

Now that we’ve explained why it’s important to have some kind of ventilation in your garage, we’ll explain how you can do it in your garage if you don’t have windows. We will list seven methods that definitely work, and we hope that you will use one of them and apply it to vent your garage. Let’s start:

Method 1: Add a Ceiling Fan To A Garage

Ceiling fans are great solutions that you can implement in your garage if you don’t have windows. Although the installations are sometimes not simple (depending on the type of garage you have), their efficiency is very high. By using a ceiling fan, you can very easily cool down a garage, even during hot summer days. Another advantage is that you can turn them on and off whenever you want.

Most ceiling fan models have different speed levels, which means that you will be able to control the air circulation as much as you need. There are different types of ceiling fans on the market. For example, there are four-bladed fans, five-bladed fans, six-bladed fans, etc. Ceiling fans with less blades are better.

Method 2: Install a Vent On Garage Roof

Adding a vent on the garage roof is another way to help you ventilate your garage. You’ll get much better air circulation in an enclosed space like a garage, which is what you ultimately want to achieve. Therefore, you’ll avoid any problems during the summer, and your garage will always have fresh air circulating.

Although this installation process is more complex than adding a ceiling fan, it will definitely pay off in the long run. Also, by adding a vent, you can adjust and regulate the temperature inside the garage. But these are additional options if you are ready to invest even more.

Method 3: Buy A Dehumidifier For the Garage

If there is not enough air circulation in the garage, moisture builds up, and the air becomes heavier. Suppose you don’t want to do any additional installations in your garage, but you want a simpler solution to vent your garage. In that case, adding a dehumidifier is a great option for you.

Having humid air in your garage can be very unpleasant, and it can affect human health and skin. Especially if you have respiratory issues. A dehumidifier is an excellent device that can help you get rid of unpleasant odors and humid air that accumulates and, at the same time, vent your garage. They are often used in homes, so why not use them in the garage too? You have a large selection of these devices, so look at a portable dehumidifier that will fit your garage size.

Method 4: Use Portable Air Conditioner

Portable air conditioners are another option you can use to vent the garage with no windows. Remember that portable air conditioners don’t need a window to work efficiently. You only need to find a way to get the hose it’s connected to through the garage and out. These devices are great for ventilation, and many houses use them. Search for the model that best fits your needs.

Method 5: Garage Insulation

Garage insulation can also be used to keep the garage more comfortable and cool, and not only warm during winter. Good insulation regulates the room temperature. For example, if the temperature inside your garage is pleasant, the garage will then maintain that temperature.

Although this may be the most expensive option of the above, it is certainly profitable in the long run. When doing insulation, it is necessary to insulate all walls, ceilings, windows, and even doors. That way, you’ll get the best results. We have already written an article on how to insulate the garage, so feel free to read it.

Method 6: Paint Your Garage

If you have a darker-colored garage (black, brown, etc.), the garage will absorb more heat in contrast to brighter colors like white, yellow, etc. Therefore, on very hot days, the garage could become unbearable to stay in. If you want a more pleasant atmosphere in your garage, paint the garage in lighter colors, preferably white. Although of all the methods, this method is the least effective when it comes to ventilation, but we put it on the list anyway.

Method 7: Use Cross-Ventilation

Another way you can create natural ventilation is if you have an entrance door to the garage. Ventilation can be achieved by opening the entrance door and the main garage door. That way, you have two openings in one room.  This method is most often used in rooms that have one window and a door. It’s also known as cross-ventilation.

Final Thoughts

The bottom line is that ventilation is necessary for the garage regardless of whether it has windows or not. If you don’t have windows, as discussed in this article, you will have to use one of the methods we mentioned earlier. However, I would advise you to add a ceiling fan or install a vent in your garage as a long-term solution. When hot days come, it will be unbearable in the garage, and the only way to get some fresh air is to do proper ventilation.
