How Installing Energy-Efficient Windows in South Union Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in South Union
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you'll find from window installation companies.
How Much Do New Windows Cost?
Generally, homeowners in South Union can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These figures are based on the specifics of your installation, including material, the location of your home, number of windows, size, 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 switching out the windows on your South Union home translates to an average energy savings of $236 to $319 each 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 installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step when considering a window installation is to clarify whether you need a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the complete window, including the frame, sill and trim. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In South Union, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in South Union
In our hunt to make your home improvements easier and more eco-friendly in South Union, EcoWatch examined many companies before settling on these. Along with energy efficiency, we reviewed several window installers in South Union and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve South Union so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have nice things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
South Union, PA Window Replacement FAQs
How much should window installation cost?
The typical cost to replace a window can range from $450 to $650. There are many factors that influence how much it costs, which include the number of windows, how energy-efficient the windows are, local labor costs, the materials used in designing the windows, styles and sizes of windows and your property's location.
What are the different kinds of windows?
There are various kinds of windows you can get for your house, such as awning windows, double-hung and single-hung windows, bay windows, transom windows, picture windows, slider windows and casement windows.
What services do window installation companies do?
Window installers go to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
