So maybe replacing your windows isn’t an option for you right now. We realize such a big project can be rather pricey. So we want to go over a couple options to help reduce energy costs.
We’ll start with window tinting. Tinting your windows at home is a viable, cost efficient option to avoid replacing windows. It’s proven to reduce cost in the summer by blocking UV rays resulting in lower electric bills and less wear and tear on your HVAC unit. In the winter it is proven to retain interior heat resulting in lower energy costs.
Another option would be enhancing your window coverings inside the house. Get better blinds and light blocking curtains, or even a roman shade or plantation shutters. This will help filter the amount of UV coming in, and heat going out.
Lastly we would recommend covering the outside of windows with an outdoor shade or awning. You can buy roll up shades to cover a large portion of windows that are victim to the afternoon sun, as well as small individual shades for each window. Just keep in mind this won't necessarily help you keep the heat in during the winter months, but it could at least help improve cost and HVAC performance during the hotter months. (We seem to get A LOT more of those than cold here in NTX).
The majority of all of these options can be picked up at your local Lowes or Home Depot, just remember to measure twice and buy once. At least I think that's how the saying goes, right?
