Garages get extremely hot during the summer season. Just like we need ways to warm the garage during winter, we need to look for methods to cool them during summer. Extreme temperatures in garages make it almost if not impossible to work. Even in a normal climate, garage temperatures are different from the rest of the house.
If you live in places with extreme temperatures, you should understand how to cool a garage. There are diverse ways to cool a garage, and it might be confusing to settle one the best. Extreme high temperatures lead to sweating and discomfort. Here I shall offer you the best way to cool a garage in summer.
What Does It Mean If Your Garage Is Difficult to Control Temperature?
Going through your daily tasks in the garage with high humidity level is quite unpleasant. Most times, it is difficult to control the temperatures in garages. This means that the temperatures will either go too high or too cold. You, therefore, need to come up with solutions to balance the garage temperatures.
Before you settle on the way to balance, you need to understand the reason behind garage temperature imbalance. If the garage temperatures are hard to control, then it means that it lacks ventilation and insulation. Insulating the garage helps you to control air temperatures.
Insulation prevents the air from getting in the garage or getting out. Therefore, if you use a heater or a cooler, the temperature will be maintained for a long period. Before buying a garage cooler or heater, it is recommendable that you have enough garage insulation, and it will assist you in saving energy.
My Garage Is Too Hot, Why Won’t It Cool Down on Its Own?
Sometimes garages become too hot, making it impossible to work. During this time, some people wait for the temperatures to come down on their own. In some garages, it may work while it may not work with others. Here are some possibilities on why your garage will not cool on its own:
1. Poor Insulation
One reason why the garage temperatures will not go down naturally is that your garage has poor or no insulation. Insulation helps in controlling the temperatures in a room. Insulating the garage wall, door, windows, and ceiling prevents air in the garage from getting out and air from the outside from getting in the garage.
2. Lack of Ventilation
Some garages are built without ventilation or windows. This could also be another reason why a hot garage will not cool on its own. Ventilations and windows assist in providing airflow in the garage. A garage without a window will heat quickly, and it will be difficult to cool.
3. Color of the Garage
Most of us do not know that a garage color can affect its temperature. Garages painted with dark colors tend to keep heat. If you want to cool the garage faster, consider painting its roof with light colors.
4. Garage Orientation and Location
If the garage faces the west, its temperatures will be high in the afternoon due to the hot sun. Without the right insulation, it may take quite a long time to cool itself down without the help of a system.
Why Should You Keep Your Garage Cool?
Controlling the temperatures in the garage is crucial for the longevity of your items, tools, and overall architecture. Cooling the garage temperatures makes it suitable to work in. Excess heat not only makes it impossible to work but also poses a risk to your working tools.
Electrical equipment is affected by hot air. You are advised to cool the garage down before switching on an electric item or using it. Using these items in an extremely hot garage may cause damage or even lead to a fire breakout.
Another reason to cool your garage is to conform to the area code. Some areas have rules that need you to control the temperature in garages. This makes the spaces more comfortable and prevents them from being neglected. At times it can even be difficult to sell a house whose garage temperature is not well regulated.
