Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could account for nearly 30% of heating and cooling usage. In Central, where the power bills are an average of $37 per month, that's almost $$134 per year wasted.
Replacement windows improve your home's insulation, not only making you more comfortable during the summer and winter, but also saving you some money and helping the environment.
As windows are so important for your home, choosing the best company for you is a big choice to make. That's why the EcoWatch team has created this list of the best window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Central Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- More efficient energy usage in your home: Because the winters can get very cold in Central, homeowners usually rely on their heater during that time. Energy-efficient windows cut back on how much heat is lost through your windows, which makes it easier to keep your house warm.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Central
When looking into window installation, each company provides varying services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
On average, Central homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These amounts are based on specific characteristics of your installation, including material, type, the location of your home, number of windows, size and more.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Central homeowners $311+ per year after replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with 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?
The first step when considering a replacement is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Central
EcoWatch reviews are different from other reviews, as we examine these companies through a sustainability lens. We've reviewed the best window installation companies in Central primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Central so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, warranty, professionalism, quality of parts, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. 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.
Central, IL Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the location of your property, the type and material of the window and the size 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.
Which type of window should I get?
Generally, double-pane windows will be 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 that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies offer?
Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
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. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the 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.
