he Best Window U-Factor for Your Arizona Home’s Energy Efficiency
When it comes to making sure that none of the conditioned air that is being produced by your HVAC system is escaping through your windows, you probably know by now that having energy-efficient windows is what matters the most. You probably also know that the right windows, combined with the right insulation, can drastically lower your utility bills by keeping conditioned air inside your home while simultaneously preventing your air conditioner or furnace from having to work too hard.
What Does the U-Factor Rating on Your Arizona Home’s Windows Mean?
I think before we can really get into the question of what is the best window U-Factor for your Arizona home, it’s important to make sure that everyone knows what a U-Factor is, especially because while it’s a part of my job every day, for the vast majority of normal folks it’s a totally foreign concept. While you may have seen it on window performance stickers, that doesn’t mean you’ve given it much thought or stopped to figure it out. And, hey, I don’t blame them.
In the most basic terms, a U-Factor is the measurement of a window’s energy efficiency. In more specific terms, that means that it’s the measurement used to indicate the amount of heat transfer a particular type of window allows. Essentially, the U-Factor lets you know what a window’s insulating power is.
…what can get a little confusing about U-Factors is that the lower the U-Factor, the better the insulation.

The good news is, though, it never gets so cold that we have to take into account freezing temperatures.
