How Installing Energy-Efficient Windows in Unity Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, such as:
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Protect your investment: The older your home is, the more likely it is that getting new 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way.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.
Estimated Cost of Window Replacement in Unity
When looking into window installation, each company offers different services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Generally, Unity homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs will vary significantly based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Unity home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from multiple companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
In regard to window installations, in general there are two types that your installer will offer: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation involves replacing a window within the old frame. This means instead of taking out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which window installation service you need, your installer should be able to assist you. Generally, the choice is based 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 Unity
EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
Because this is a guide for Unity, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Unity.
Work Quality
We're certain 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 ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Unity's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Unity window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Unity, PA Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is often influenced by 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 a decent amount of money a year in energy bills.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a involved process that can take a lot of time, so it's best left to the professionals.
When is the best time of year to replace 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 ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
