Is Your Upstairs Too Hot? 3 Guaranteed Ways to Cool it Down

August 20, 2014

Is your Florida home’s upstairs 10 to 20 degrees hotter than downstairs?

Pretty much makes it impossible to sleep upstairs, right? The ceiling fan hardly helps. And you can’t leave your AC on all the time because that costs big $$$.

So is there a solution?

Yes, 3, in fact!

1) Add heat-absorbing tint your upstairs windows

According to ENERGY STAR,  “A standard double-pane window allows approximately 75 percent of the sun’s heat into your home.”

You can prevent heat gain through your upstairs windows by tinting your windows.


Window tinting helps block infrared rays, which carry heat energy into your home.

According to the International Window Film Association, a window tint film can “reject up to 80% of the sun's heat. In summer your home is cooler and more comfortable, so you can save on energy bills. In winter, some window films trap room heat for year -round comfort.“

2) Add insulation to the attic

Got an older home? That may be why your upstairs is so hot.

The North American Insulation Manufacturers Association (NAIMA) says that if your home was built in the 90s or earlier, you likely have one of the 46 million under-insulated homes in the U.S.

So you may need to add more insulation to keep your upstairs cool.

According to ENERGY STAR, your attic has enough insulation when it’s:

  • Well above the ceiling joists so you cannot easily see them (usually 10-14 inches of insulation, depending on the insulation type)
  • Evenly spread all the way to the edges of your roof

3) Fix leaky air ducts

Your upstairs may be too hot because all the cool air just isn’t getting there.

According to ENERGY STAR, the average home loses 20-30% of the air that moves through the duct system due to:

  • Leaks
  • Holes
  • Poorly connected ducts

So, your AC may be working properly, but the cold air just isn’t making its way to the upstairs rooms. That would explain why it’s so darn hot.

Signs your air ducts are leaking include:

  • Extremely high energy bills
  • Some rooms never get cool (your upstairs rooms, for instance)
  • You can see kinked ductwork in your attic and crawlspace
  • Extremely dusty home and rooms

Have professional AC contractor seal your ducts if this is the issue.
