Why is my House Too Hot?

If you are finding it difficult to keep your home cool in the summer, especially the upper floors, there are a few possible explanations. It could be that your air conditioner doesn’t have enough power to provide sufficient cooling. You could have leaks or blockages in your ductwork that prevent cooled air from reaching some rooms in your home. Or it could be a lack of insulation in the walls, poorly performing windows, or air leaks. But if your air conditioner is properly sized and functioning correctly, and you can rule out these other conditions, then the problem is most certainly coming from your attic.

Heat Build-Up in Attic
It is very common for heat to build up in the attic – sometimes to 140 degrees or higher – and then seep down into your living space. Air leaks and insufficient insulation on the attic floor can intensify the problem.

Reducing the temperature in your attic is among the best ways to make your home more comfortable and lower your home’s cooling costs. Consider sealing air leaks, adding insulation and improving attic ventilation, which will help reduce heat gain in the summer and heat loss in the winter. Beyond that, it can help tremendously to keep the heat out of the attic in the first place. How? With radiant barriers.

What is a Radiant Barrier?

A radiant barrier is a reflective surface that literally reflects the heat that hits your roof, back out of the roof, rather than down into your attic. This is one of the simplest and most innovative ways to reduce the amount of heat in your attic.

Reduce Attic Heat
Radiant barriers can reduce the temperature of the hottest of attics by over 40 degrees, bringing a stifling hot 135 degree attic down to a more manageable 95 degrees.

Radiant barriers come in various forms, but some are simpler and less expensive in reducing attic heat in an existing home and prevent it from seeping down into the living space below.

Your attic still won’t be the best place to store chocolate or spend your summer afternoons, but the lower temperature, when combined with proper ceiling insulation, will reduce the heat beating into your home – and you’ll save money because your air conditioning system won’t have to work as hard.
