How Installing Energy-Efficient Windows in Sunnyvale Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- More efficient energy use in your household: Because the summers can get pretty hot in Sunnyvale, homeowners usually rely on their air conditioner a lot. Energy-efficient windows decrease the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Sunnyvale
Windows come in different styles, purposes and shapes, so costs and services will vary tremendously depending on several factors. Below, we go over the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
On average, Sunnyvale homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at about $600. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you understand what's best for your needs. In Sunnyvale, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Sunnyvale
EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Sunnyvale and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Sunnyvale so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Sunnyvale's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Sunnyvale window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Sunnyvale, TX Window Replacement FAQs
How much does a window install cost?
The typical cost to replace a window can range between $450 and $650. There are a variety of factors that affect the cost, which include styles and sizes of windows, your property's location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows and local labor costs.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
You should hire a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
