Other than when going into the attic, I would be concerned about leaving the attic access door open. I understand the venting of heat into the attic, but there are 2 issues at play here.

(1) You are taking heat from the garage and moving much of it into the attic where an additional heat load is added to the ceiling making your air conditioner run harder and longer (i.e., many more KWHs consumed plus wear and tear on your AC).

(2) Many house fires begin in the garage and the open attic door will allow it to engulf the entire house once it moves into the attic. There are no walls in the attic.

My 2-cents ----- I would close the attic access completely, and leave the screen garage door open.

What you are doing does help with air flow. You are better off using the screen on your garage when it’s really hot out. I have a solar ventilation fan in my roof. It helps pull the hot air from my attic. I’ve also got a fan in my garage ceiling that pulls hot air from the garage into the attic, so I’ve got good air flow.

I have a garage full, a 20' bass boat, an Enclave, golf cart, etc. I had a ceiling fan installed above my workbench. I don't open the attic panel/step for ventilation, I took a hole saw and sawed many holes in the attic panel and this is full time ventilation. I use the garage screen door whenever possible for ventilation. I lower the main garage door to about a foot short of closing, it keeps the rain out and also ventilates at the same time.

How many house fires have there ever been in TV, very, very few. I have a thermostat controlled attic exhaust fan, a vent in my attic stairs cover, and 3 vents on the bottom of my garage doors. When it's hot enough in the attic for the fan to come on there is a constant flow of air coming into the garage and out through the attic. I'm not too worried about a fire with that little vent in the door, catastrophic damage or injury is more likely from a tornado or hurricane than a fire. There was more damage from the 07 tornado than there will ever be from fires in TV.

My exact thought; if only they put as much thought into making a better golf swing.

We’re having a thermostatically controlled vent fan put in our garage in a couple of weeks; we had one in our previous home that helped out considerably with the heat.

I put two vents at bottom of my garage door. Problem with attics door open the heat come down from attic unless got good breeze. I try push cooler air up in attic cause I have stuff stored in there. And yes 95 degree air lot cooler than 130 degree air at top.

Well! I may loose sleep 💤 over it.

A quick physics lesson. Hot air is a a slightly higher atmosphere pressure than cooler air. Therefore hot air will displace cooler air. Unless you have a exhaust fan in your garage or attic to create an flow of air simply opening the garage will not make the interior of the garage cooler.

Call the Solar Guys. They sell what’s called a Garage Cooler with a fire fuse and damper for safety. I sold many in my business years ago and they work great and the thermostat shuts them down as the temp goes down.

I agree 100% I’ve had two homes in the villages both had screens, motorized screen doors from Michelle‘s screen doors in Ocala, excellent. It really helps when you drive your hot car into the garage and have some ventilation. The cost of the screen door is about $2500 and worth every penny and it comes in different colors. I never heard about leaving the attic door cracked but I’m gonna check into that, thanks very much and good luck staying cool 😎

If not working or sitting in the garage, the garage screen door is being used to ventilate the garage. The attic door is a fire-block by code. If you leave it open and happen to have a fire in the garage, it will spread to the entire house quickly. With the attic door open and if a fire occurs, you may void your insuance. You can install a garage ceiling fan (coolmygarage.com) that will pull the cool air up through your attic and out the roof vents. The cool my garage exhaust fan also has a thermo damper that automatically closes when fire occurs. My garage attic never above 105, with the thermostat control.

Best answer yet.
