How Installing Energy-Efficient Windows in Los Angeles Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:

• Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, 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 damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Los Angeles

When considering window installation, each company provides varying services and prices. Let's go over some average costs and services.

How Much Do New Windows Cost?

Generally, homeowners in Los Angeles can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. These figures vary depending on specific characteristics of your installation, such as size, the location of your home, material, number of windows, type and more.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Asking for free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're unsure which kind of window installation service you need, your installer should be able to assist you. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Los Angeles

EcoWatch reviews are different from other reviews because we examine these companies through a sustainability lens. We have decided to evaluate the top window replacement companies in Los Angeles 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 reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Los Angeles, we only included companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Los Angeles.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of installation, professionalism, quality of parts, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
