I'm looking to cool down my house this summer, and since our main entry is through the garage, I'm wondering if insulating the garage would have any impact on the temperature inside my home. The garage isn't climate-controlled, but it shares two walls with living areas in the house. Will insulating the garage door make a noticeable difference?

Honestly, it's probably a good idea, but it depends on how well those shared walls are insulated already. If they're lacking, that might be where to focus your efforts first. Also, opening your garage door in the morning can help cool it down before it heats up during the day.
One of the biggest culprits for energy loss is air gaps around your garage door. Make sure it seals properly! I got a door seal for about $40, and it works wonders. Just ensure you have good weather stripping between your garage door and the house too. That could really enhance the effectiveness of insulation.
Insulating your garage door might help a bit, but it's not a magic solution. If the walls between the garage and your house aren't well-insulated, it likely won’t make a huge difference for the rest of your home. You should check your insulation levels and also consider proper ventilation in your attic first.
