How Installing Energy-Efficient Windows in Santa Ana Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Santa Ana
When considering window installation, each company offers varying services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Santa Ana can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. These numbers vary depending on the specifics of your installation, like the location of your home, size, number of windows, material, type and more.
It’s also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Santa Ana home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you’re unsure which kind of window installation service you should get, your installer can help you out. Generally, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Santa Ana
EcoWatch is different from most reviewers, as we examine these companies through a sustainability lens. We have evaluated the best window installation companies in Santa Ana mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Santa Ana so you can find the best window installation company near you.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, warranty, cost, professionalism, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Santa Ana’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Santa Ana window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Santa Ana, CA Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are casement windows, double-hung and single-hung windows, awning windows, transom windows, bay windows, slider windows and picture windows.
When do I have to use a window installation company?
Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer option.
When is it time to replace your windows?
Windows typically last 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, it’s probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
