Keeping Your House Cool During Hot Summer Weather

To keep your house cooler and reduce air conditioning bills during the summer:

  • Paddle Fans: To keep cool use paddle ceiling fans set to rotate in a counterclockwise direction when looking up. Since they don’t cool the air, just the people in the room, run paddle fans only when the room is occupied.
  • Attic Vent Fans: Add an attic exhaust fan near the peak of your roof to keep the attic cooler, lower air conditioning bills, and make your roof last longer.
  • Block Sunlight: Lower blinds or close curtains on sunny windows during the day to reduce solar heat gain in your home.
  • Apply Window Film: Another way to reduce solar heat gain in your house is by applying window film to the inside of single pane windows and glass doors.
  • Install Low-E Glass: When installing new windows on your home, make sure the glass comes with a Low-E coating suitable for your climate. Low-E coatings also reduce UV rays from sunlight that can damage and fade furniture, fabric, and rugs.

Further Information

Danny Lipford: Now, heat can make you very uncomfortable. There are a few things that you can do to make life a little easier. One of the easiest ways to cool off this time of the year is the addition of a ceiling fan to a room. Even if you have air conditioning the constant moving air generated by a ceiling fan will make it feel cooler than it actually is. And adding one to an outside living area can make all the difference in how comfortable that space might be. The key thing to remember is that in warm weather you want that fan turning counter-clockwise as you look up at it from the ground.

Adding an exhaust fan to your attic is another great way to stay cool, because it pushes out the hot air at the top of your attic, drawing in cooler air from the socket or overhang areas. If you choose one that’s powered by its own solar cells you can see all these benefits without adding one cent to your utility bill.

To minimize heat gain in your home from exposure to the sun there’s several things that you can do. The easiest is simply draw the blinds to stop some solar heat gain, or add window film to the inside surface of single-pane windows to do the same thing without obstructing the view. The ideal solution though is to install windows with a Low-E coating. This coating filters the sunlight, letting in visible light while it blocks UV rays. So, you not only keep the inside cooler, you protect your furnishings from fading as well.


  1. I’m sure you get asked this all the time! I can’t find a clear answer. My HVAC ductwork is in the crawlspace. Should I open or close my crawlspace vents? We also have a vent fan but the more I read the more I see that they don’t help with decreasing humidity. We had an issue with moisture when we bought the house and our wood floors in bedroom were cupped. As soon as we moved in, I opened the crawlspace vents and of course we had the vent fan installed. The cupping went down a huge amount! I just don’t want our floors and under our house to be more ruined than it already is. Any advice is appreciated. I do know I will need new vapor barrier at some point (crappy job from 21 years ago) thanks!!!!!

  2. Another thing that can significantly affect cooling bills is installation of ridge vents when replacing the roofing. I like the idea of the solar exhaust fans too, but I’ve read that the electrically powered ones use about as much energy as they save.

  3. Enjoy reading your home owners tips. I have one tip that seems to lower the air downstairs where we stay most of the time. Our upstairs is hardly used anymore with children gone, but we run the ceiling fans in those upstairs rooms and keep the air condition set on 80. This keeps our living areas downstairs cooler because the upper floor stays cool . Our middle floor hardly runs air unit all day.
