Most people don’t give much thought to garage ventilation, preferring to concentrate on other parts of their houses. However, your garage must be well-ventilated. Otherwise, it may cause a bunch of problems down the line.
What Is the Ventilation Process?
The process of delivering fresh air into an area is known as ventilation. That clean air is either mixed in with or replaced by the current air in the room (known as mixing or dilution ventilation) (known as displacement or piston flow ventilation).
How Do You Ventilate a Garage-Attached House?
Airing out of your garage is not required by law. The Environmental Protection Agency (EPA) suggests venting your garage to remove carbon monoxide and other harmful pollutants. They recommend utilizing a 100 CFM ducted or 80 CFM un-ducted fan in home-connected garages.
Installing an exhaust fan is the most common ventilation technique in a connected garage. Determine the size of your garage first so you may get the appropriate exhaust fan equipment. After determining the dimensions of your garage, get a self-installation exhaust fan kit with sufficient power to air a garage of your size. We’ll show you how to install an exhaust fan.
How Should a Detached Garage Be Ventilated?
Because there is a minor threat of harmful gases and carbon monoxide escaping into the house’s living areas, there is less urgency in the ventilation of a detached garage. However, if you do a lot of work in your garage, you might want to think about it as a way to keep it cool. There are several ways to ventilate your detached garage:
- Install vents
- Install windows
- Place a window fan
- Install an exhaust fan
Wall vents function similarly to windows, however they remain open at all times. They might not be the greatest solution if you reside in a snowy climate. Having said that, some wall vent types have a lever for closing the vents during the winter.
A wall vent allows the hot and humid air in your garage to escape. However, be certain that there are intake vents as well. To enhance airflow, the basic guideline of ventilation is to have both intake and exhaust vents. Because there are no intake vents, there is no way for new air to enter the garage, hence the present contaminated air will remain.
In order to provide adequate ventilation, a wall vent should be installed on one side of the garage at the bottom and another at the top. Cool air is drawn in through the bottom vent, which rises as it becomes hot. Hot air is vented through the top vent. By utilizing cross ventilation and convection, this setup produces more ventilation.
Garage door vents
It isn’t easy to drill through the wall of your garage and put vents there, but you can do it by installing them on your garage door. If you are a DIYer, this might be a better option for you. Top and bottom vents are located on the side and top of the garage door, usually to the sides. The bottom vent serves as an intake vent, allowing cooler outside air in, while the top vent removes hot air.
The drawback of this setup is that it isn’t suitable for large garage spaces. This is because the path of the airflow runs between the vents to the bottom and the top of the door and as a result it will not circulate air throughout the garage space.
How to Choose the Right Garage Fan?
Several varieties of garage fans are available on the market to select from. However, when shopping for a garage fan, keep the following factors in mind:
- CFM: The greater the CFM number, the more airflow it creates, allowing your garage to cool off faster. The size of your garage determines the number of CFMs your fan should have. A smaller garage does not require a high CFM fan to cool it adequately.
- Fan Type: There are several varieties of fans to pick from, including wall-mounted, blower, and ceiling fans.
- Materials: For your garage, get a fan with metal blades because they are more durable and withstand diverse climatic conditions. Metal blades are also better at circulating air.
Why Is Garage Ventilation Required?
Your garage is where you park your car and undertake most of your DIY home improvement chores. These activities emit harmful compounds into the air, which might linger in your garage if it is not adequately ventilated. These dangerous gases can enter your home and contaminate the air.
A well-ventilated garage also helps to maintain a low temperature and humidity level. This keeps mold away while keeping you comfy in your garage. Mold is harmful to one’s health and can damage surfaces where it grows. If there is insufficient ventilation, the temperature in your garage may rise to 10 to 18°F higher than the temperature outside. If the temperature in your garage becomes too high, the items stored inside, such as paint and electronics, may be damaged.
Open a window or door to let fresh air into your garage. If your garage has no windows, you might want to get a fan or add a vent to the roof. The best way to increase your garage’s airflow is to get a ventilation fan.
Do garage exhaust fans merit their price?
Installing a good garage exhaust fan to properly ventilate your garage may be beneficial if you struggle with a humid, hot, and uncomfortable garage. It will help reduce humidity, heat, and airborne allergens while enhancing the comfort and quality of the air.
If your garage lacks windows, you may replace them with vents. Vents bring in the fresh air instead of exhaust fans, which expel interior air to the outside. Vents should be installed high on your garage walls or on the roof so that the warm air that rises to the roof may be discharged via the vents, keeping your garage cooler.
