No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

The average cost for home window tinting is around $600, with most homeowners paying between $150 and $1,600. Costs can also be calculated per square foot, typically ranging from $2 to $100, or per window at around $75 each. For example, tinting one or two windows might cost between $200 and $350, while a larger project of 13 to 15 windows could range from $4,124 to $4,747.

Several factors influence the total project cost, with the number and size of the windows being the most significant. Other key factors include the type, shade, and quality of the tint film, as well as labor costs. Additional treatments, such as low-emissivity (low-E) coatings, can also increase material costs.

Window tinting offers several benefits, such as making your home more energy-efficient by blocking harsh sunlight, protecting furniture from fading, and increasing privacy. For this reason, many homeowners choose to tint only the windows in specific areas where direct sunlight and privacy are primary concerns.

The best windows to tint are those that get the most direct sunlight—particularly sunroom windows or windows facing the south or east where the sun shines most brightly throughout the day. If your pets have favorite windows to lie in front of, you may want to consider those, as well, to protect their skin from sun damage.
