The benefits of residential window tinting are numerous. By blocking heat from the sun from entering into your home, it enables you to cut down on your energy bill by spending less on AC in the summer. To a lesser extent, it works the other way as well. During winter, window tinting can help retain interior heat, and you’ll end up using less energy to heat up your house through those cold months. It’s also a wise investment for your furniture, as it can cut down dramatically on the impact of light damage. With all these benefits, it’s easy to see why so many people invest in residential window tinting. If you choose to do so yourself, here are some common mistakes you should be sure to avoid.
