With temperatures feeling like it's over 100 degrees outside, you're probably staying as cool as possible inside.
Your air conditioner is probably working overtime which means your bills might end up over budget.
It doesn't have to be that way.
"Depending on the age of your home, you can easily save 20 to 40 percent," says Jason Puffenbarger.
He makes a living making sure your living room stays the right temperature year round in the most energy efficient way.
And finding your home's hot spots could save you anywhere from $400 to $800 a year.
"Most of these things I'm talking about aren't that expensive. It's caulking, it's taping."
Puffenbarger says check around your rim joist in your basement to make sure any piping or vents outside have caulking around them.
Also, check canned lights in your upstairs rooms and bathroom fans to see if there's a gap between the vent box and the dry wall. If there is, cheap caulking can make for a quick fix.
If all those leaks are sealed up, turn your thermostat up just 10 degrees for 8 hours out of the day, and you can save 10 percent on your energy bill.
