Why Your Garage Feels Like an Oven and What You Can Do About It

If your garage feels like an oven in July, you are not imagining it. Southeast Michigan summers can bring heavy heat, humidity, and long stretches of sun that turn garages into some of the hottest spaces in the home.

And while most people think of the garage as “just storage,” the temperature in that space can affect a lot more than your tools and holiday decorations.

It can impact your comfort, your energy bills, and even the rooms connected to the garage.

Why garages get so hot in the summer

Garages often have less insulation than the rest of the home. They may also have older windows, gaps around exterior doors, or a garage entry door that does not seal properly.

If your garage faces direct sun or has poor airflow, the heat can build quickly and linger long after the sun goes down.

Check the door between the garage and your home

One of the most important places to inspect is the door between your garage and your living space. If this door is old, damaged, poorly sealed, or not closing tightly, hot garage air can creep into your home.

That can make nearby rooms feel warmer and force your air conditioner to work harder.

Look for gaps around exterior garage doors

If your garage has a side entry door, check for light coming through around the frame. Gaps, cracked weatherstripping, and warped doors can all allow hot outdoor air to enter.

Replacing an old garage entry door can help improve comfort, security, and the overall look of your home.

Don’t forget garage windows

If your garage has windows, they may be contributing to the heat. Older or inefficient windows can allow significant heat transfer, especially if they face south or west.

New windows can help improve insulation while still allowing natural light into the space.

A more comfortable garage starts with better barriers

You may not need to fully finish or air condition your garage to make it more comfortable. Sometimes, replacing old doors and windows is the practical first step.

Better seals, stronger materials, and more energy-efficient products can help reduce heat transfer and make the space feel less brutal in the middle of summer.
