How to Keep Your Garage Cool in the Summer and Warm in the Winter

How to keep a garage cool in summer and warm in winter

Many people today use their garage door as the main entryway to their home as opposed to the traditional front door, resulting in garage doors opening and closing numerous times throughout the day.

In the colder months, this means letting more frigid air enter, and in the hot months, more heat is coming in. The best way to combat extreme weather in the winter and the summer is to insulate your garage and make it climate-controlled, keeping it nice and warm in winter and cool in the summer, adding extra protection and saving you energy.

Garage Door Insulation Kits – The Best Way to Keep Your Garage Warm in the Winter and Cool in the Summer

While adding space heaters in the winter or portable fans in the summer can help regulate how warm or cool your garage is, insulation is ultimately the best way to keep your garage cool in summer and warm in winter. Insulation helps control your garage temperature since it reduces air loss and prevents air from getting in. Since garages are one of the worst parts of a home when it comes to energy efficiency, insulation is crucial. 

When you control your garage’s climate and temperature using insulation, you’re also keeping energy costs down as you reduce the amount of energy necessary to heat up or cool down the rest of your home. Insulating your garage doors with insulation kits also makes your garage door more sturdy, since insulation helps strengthen the door and makes it less susceptible to dents from accidentally hitting it or other damage by natural elements.

Insulation kits also reduce noise from opening and closing your garage door and decrease any noise from outside your door. Insulation allows you to use your garage for your favorite hobbies or recreationally, making it a comfortable and controlled atmosphere no matter the weather.

When you search for an insulation kit, look for one with a high R-value. R-value measures how effective a material is at insulating based on its chemical properties and thickness. The higher the R-value, the more effective the insulation. However, when it comes to R-values for garage doors, they can sometimes be measured using different methods. This makes it challenging to figure out what R-value you specifically need to insulate your garage door, so it’s always best to seek professional assistance to find the right insulation kit for you.

Additionally, insulation kits require careful precision to cut the insulation to fit your garage door panels perfectly before securing them on. To ensure that your insulation kit works the way it should and your garage can stay warm in the freezing cold and cool in the scorching temps, trust a professional to install your garage door insulation.

At EXL Garage Doors, we offer insulation kits and professional installation services, as well as a variety of Clopay insulated garage doors for your home if you’re looking for a complete door update.

How to Keep Your Garage Warm in the Winter

Even if you only use your garage for storage, freezing winter temperatures can infiltrate your garage and affect your belongings, such as your car. Colder temperatures can ruin your car’s battery, thicken its fluids, cause low tire air pressure and lead to unreliable wiring and spark plugs.

Plus, if you often work or do any recreational activity in your garage, it needs to be habitable, and freezing temps can quickly make it unbearable. Garages act as a nice buffer as far as temperature goes from the outdoors to inside your home. Garages should be warmer than outside, and, though they may not always be as warm as your home indoors, you should be able to go from your home to your garage to grab something without having to put on all your winter layers.

In addition to adding insulation, you can use other tips to help keep your garage warmer when it’s cold outside. Try the following to control your garage’s temperature year-round.

Start By Cleaning Your Garage

1. Clean Your Garage

To find the best way to control the climate of your garage during the winter, start by giving your garage an excellent, thorough cleaning. After all, what good is adding improvements to your garage if it’s still a mess? 

2. Check Your Weather Stripping

After you organize and clean it up, inspect your door and look at your weather stripping. Over time, your weather stripping could crack and break, and if water finds its way in, it can freeze and make your garage door stuck, unable to open. Broken weather stripping also leads to some severe air leaks which allow the cold winter air to come in.

To replace your weather stripping, remove the existing weather stripping and scrape off any leftover sealant (not all doors will have sealant that needs to be removed, especially doors that were installed within the last 20 years). To put on your new weather stripping, you must accurately measure it and line it up to the door to ensure your seal is tight. Close the garage door and put the stripping down so the rubber flap is pressed against the door.

3. Seal Other Air Gaps

Your weather stripping isn’t the only place cold air can enter your garage — other doors and window units are also prime spots for air infiltration. Inspect the area carefully to see if the caulk has broken. If the sealant is in bad shape, it can also promote mold growth or wood rot in addition to letting in cold air.

It’s generally best to remove the old caulk before applying new. Start at the top and use consistent pressure with a putty knife or other sharp tool to remove it, then clean the surface thoroughly before applying the new sealant. For extra protection, add affordable plastic window film to help keep cold air out.

4. Add Insulation to Uninsulated Walls and Ceilings

If the exterior walls and your garage’s ceiling aren’t currently insulated, now’s the time to change that. You have multiple options for doing so, including:

  • Spray foam insulation.
  • Rigid foam insulation.
  • Batt foam insulation.

This small addition can also help reduce noise, which is useful for those who use the garage to pursue hobbies.

5. Consider Adding a Heater

You can also explore various heater options to keep your garage warm during the winter months. Think about the amount of space you have in your garage and shop around accordingly. 

If you’re scarce on space, you may even want to consider a wall-mounted heater. Mounted electric heaters are easier to install than a forced-air heating system, so you may be able to install them on your own. However, you could also go with a forced air heater or convection heater. 

For convenience, a portable space heater or propane heater could work best since they come in various sizes, making it easy to find one that works for your space and meets your heating needs. Unit heaters are also compact and relatively simple to install, and you can choose to run it on electricity or gas. You may opt to put in a mini-split heat pump to save even more energy.

How to Keep Your Garage Cool in the Summer

Similar to how you want to protect your garage from frigid winter air, you also need to keep it cool when summer brings extreme heat. Our tips for helping do that include the following.

1. Take Advantage of Natural Ventilation

In addition to insulation kits or insulated garage doors, you can find ways to use natural ventilation to keep your garage cool, especially if it has no windows. By opening any outside-facing doors, windows or other doors besides the one that leads to your home, you increase the air circulation inside your garage, keeping things moving and preventing your garage from feeling too hot.

2. Plant a Tree

This solution is good for the environment, wildlife and your wallet. Adding a tree can help shield your garage from the sun during the hottest parts of the day and maintain a lower temperature inside. 

Some shady trees include walnut, maple, ash, oak and magnolias. Since they lose their leaves each fall, you’ll benefit from the winter sun to keep your garage warmer during the cold months.

3. Let Your Vehicle Cool First

Pulling a hot car into a garage and closing the doors traps the warmth in your garage space as your vehicle cools down. A better solution is to park your car in a shady spot to let it cool first and keep the extra heat out.

4. Try a Fan

Portable fans are an affordable option that you can set up near your open doors, pointed inside your garage to draw the cool air from outdoors and pump it into your garage. You can choose from several styles of fans, such as pedestal fans, box fans or high-powered shop fans. Still, you should note that fans don’t really improve the overall garage temperature and climate as much as they boost airflow, making it feel significantly cooler inside your garage.

You could also install a ceiling fan if your garage permits. Typically, garages need to be at least 8 feet tall to install a ceiling fan. You must also make sure the blades of the ceiling fans are between 7 and 9 feet above your garage floor and between 10 and 12 inches under the ceiling. 

5. Consider the Benefits of Air Conditioning

Before you decide to incorporate air conditioning into your garage, you should think about how often you’re using it and how cold you need it to get. If you spend a lot of your time in your garage and determine air conditioning is a necessity for your garage, consider installing a window air conditioner unit or a portable floor unit as a more affordable airflow option.

6. Keep Your Garage Clean and Organized

Keeping a clean, organized garage will also benefit you in the hot summer months as airflow can circulate better when there’s no clutter around your garage. As some other added methods you could incorporate to beat the heat, consider installing some attic vents for heat to escape through or put in a dehumidifier for humidity control to prevent your garage from feeling like a summer swamp. Protect your belongings and work in comfort by discovering the best approaches for how to keep a garage cool in summer.
