How Installing Energy-Efficient Windows in South Union Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to make the switch:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way.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 home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on electricity bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save around $296 annually on your energy bills in South Union.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 467 pounds per year on average.
Estimated Cost of Window Replacement in South Union
Let’s take a look at the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range from $200 to $1,200. This is due to the fact that the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $296 a year on your energy bills in South Union.
Something else that influences the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your professionals will replace the full window, including the frame, sill and trim. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which kind of window installation service you should get, your installer can advise you. In general, 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 South Union
In our search to make your home improvements easier and more eco-friendly in South Union, the EcoWatch Reviews team assessed dozens of companies before landing on these. We have decided to evaluate the best window installers in South Union mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient 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
Because this is a guide for South Union, we only included companies that cover the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in South Union.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, quality of parts, professionalism, cost, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
South Union, PA Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the types of windows?
There are various kinds of windows you can get for your house, such as picture windows, slider windows, double-hung and single-hung windows, transom windows, awning windows, casement windows and bay windows.
What services do window replacement companies offer?
Window installers visit your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. 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 house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
How long does it generally take to install windows?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
