Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house’s energy efficiency can also have a big impact on home energy conservation. If your windows are outdated or drafty, you could be losing 25-30% of your home’s heat or cool air right out of them.
That’s also bad news for the environment, as the extra energy required by damaged windows increases your carbon footprint.
Efficient windows are of particular importance in North Union, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $296 each year.

How Installing Energy-Efficient Windows in North Union Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could benefit you:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $296 annually on your energy bills in North Union.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in North Union
Let’s take a look at the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $296 a year on your energy bills in North Union.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive 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 question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
If you’re still trying to decide which type of installation to get, you can consult with your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in North Union
The EcoWatch Reviews team is different from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for North Union, we only included companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in North Union.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
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
Due to North Union’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of North Union window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
North Union, PA Window Replacement FAQs
How much does window installation cost?
The typical cost of replacing a window ranges between $450 and $650. There are many factors that influence how much it costs, including your property’s location, styles and sizes of windows, how energy-efficient the windows are, local labor costs, the number of windows and the materials used in designing the windows.
What are the most common kinds of replacement windows?
There are several different types of windows you can get for your house, such as bay windows, slider windows, double-hung and single-hung windows, transom windows, awning windows, picture windows and casement windows.
Can you install your own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window installation company can help guarantee that the job is done properly and that you won’t have to spend the time and effort to do it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. 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 isn’t necessarily a big factor. What’s most important is that the weather should be dry.
How often should you replace your windows?
Windows generally last about 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.
