Garages can become unbearably hot in the summer, making them uncomfortable to use for their intended purpose. Whether your garage is a home for your car or you have had a garage conversion and use your garage as an extra living space, you will want to manage the heat. Below, we share practical tips on how to keep your garage cool so you can get the most out of the space year-round.
How to Keep Your Garage Cool
Insulate the Garage
Proper insulation is essential to keeping your garage cool. Insulation helps regulate the temperature by preventing heat from entering in the summer and retaining warmth during colder months.
- Insulate the Walls and Ceiling: Insulating the walls and ceiling reduces heat transfer from the outside. Fiberglass batt or spray foam are popular insulation materials. Choose the right R-value based on your climate and budget.
- Insulate the Garage Door: Garage doors can be major sources of heat gain. Insulated doors or adding insulation panels can prevent heat from entering and improve overall temperature control.
Use Light-Colored Paint
The color of your garage’s exterior can impact how much heat it absorbs. Using light-colored or reflective paint on the garage walls and roof helps reflect sunlight and reduce heat absorption.
Use Ventilation to Your Advantage
Proper ventilation is key to reducing heat buildup in your garage. Without it, warm air can become trapped inside.
- Install Vents: Adding high and low vents promotes airflow. Cool air enters through the lower vents, while warm air rises and escapes from the higher ones, improving air circulation.
- Use Exhaust Fans: Exhaust fans are an effective way to remove hot air from the garage. They are especially useful in garages that lack natural ventilation, helping to maintain a more comfortable temperature.
- Install a Ceiling Fan. A ceiling fan circulates air and creates a cooling effect, making the space feel more comfortable without dramatically lowering the temperature.
Install Reflective Window Films or Shades
If your garage has windows, sunlight streaming through them can raise the internal temperature. To reduce heat gain, consider installing reflective films or thermal shades.
- Reflective Window Film: Reflective window films block much of the sun’s heat. These films also reduce glare and improve comfort inside the garage.
- Thermal Shades: Thermal shades add an extra layer of insulation to your windows. These are particularly helpful for garages converted into living spaces, as they keep the interior cool during the day and warm at night.
Install an Air Conditioning System
Consider installing an air conditioning system for added comfort. This can be particularly useful if insulation and ventilation are not sufficient to maintain the desired temperature.
- Ductless Mini-Split System: A ductless mini-split system offers efficient cooling without the need for ductwork. It is ideal for garages that have been converted into living spaces, such as home offices or gyms.
- Portable Air Conditioners: Portable air conditioners are a flexible option for smaller garages. These units can be moved as needed but may not be as effective for larger spaces.
Seal Gaps and Cracks
Small gaps around windows, doors, or walls can allow hot air to enter and cool air to escape, making your cooling efforts less effective. Sealing these gaps will help maintain the temperature inside your garage.
- Weatherstripping: Install weatherstripping around doors and windows to block air leaks. This is an inexpensive yet effective way to keep your garage cool.
- Seal Cracks in the Walls: Look for cracks in the walls or foundation and seal them with caulk. Even small cracks can allow hot air to enter and compromise your efforts to cool the space.
Add Landscaping Around the Garage
Landscaping can provide natural shade, lowering the amount of heat that reaches your garage.
- Plant Shade Trees: Planting trees near your garage blocks sunlight, helping to cool the space naturally. Choose fast-growing trees that provide ample shade during the hottest months.
- Install Outdoor Awnings: If trees are not an option, install awnings or shade cloths above windows or garage doors. This will protect your garage from direct sunlight and reduce heat buildup inside.
