An air conditioning unit turns on when your house starts heating up. This is a key point to understand when you are trying to understand AC efficiency. An AC unit will do nothing to prevent your home from heating up in the first place, and the more your home heats up, the more your AC unit has to run. Thus, if you want to decrease your cooling costs, you need to find ways to decrease your heat gain. Highly efficient windows can drastically decrease your heat gain and improve your AC efficiency.
What Makes a Window Inefficient?
In order to know if you have efficient windows, you need to know what makes them inefficient. A single pain of glass will allow heat to easily transfer from inside your home to the outside of your home. Double-pane windows will separate the inside pane from the outside world by sandwiching a layer of gas between the windows. While this will help increase a window's efficiency, it will do nothing to prevent the sun's UV rays from streaming through your window and heating up the interior surfaces of your home. Thus, when you seek to improve your home's energy efficiency, you need to prevent UV rays from entering your home.
How You Filter out UV Rays?
It doesn't matter how many layers of glass or what type of gas manufacturers put in your window panes, they will not stop UV rays from entering your home. Window films, on the other hand, can be effective. A good window film will have a reflective layer, which will deflect the sun's UV rays before they have a chance to heat up your home. In fact, a good window film will decrease your cooling costs by up to 23%.
The best part about window film is that it is inexpensive and can be applied by the homeowner. Thus, for a little bit of money, you can put a big dent in your cooling costs. While many people focus on their AC unit when they try to improve their home's energy efficiency, running out to buy a new AC unit will cost a lot of money. If you have an older AC unit, you may need to replace it. Installing window film will help you to decrease cooling costs, which will help you save money to replace your AC unit when the need arises. If you already have a highly efficient AC unit, then window films will still help to keep your costs. down.
