Most Lake Worth homeowners see 15-25% reductions in cooling costs during summer months, with the biggest savings on homes with west and south-facing windows. The exact amount depends on your home’s size, current efficiency, and how much direct sun exposure you’re currently fighting.
Here’s why exterior shades work so much better than interior treatments: they stop heat before it gets through your windows. Interior blinds only filter light after heat has already entered your home, sometimes even trapping that heat between the glass and fabric.
The savings show up fastest during peak afternoon hours when your AC works hardest. Many customers notice the difference in their first month’s bill, especially when they combine exterior roller shades with smart controls that adjust automatically based on sun position.
