Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a big impact on home energy conservation. During the winter months, the last thing you want is your heat to leak out of your outdated windows.
That's also bad news for the environment because the extra energy required by leaky windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also considering cost, customer satisfaction and service area.

Calculate how much you can expect to pay for window installation and replacement in Carnot-Moon, PA using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in Carnot-Moon Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, such as:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- More efficient energy usage in your household: Because the summers can get quite hot in Carnot-Moon, homeowners often rely on their air conditioner during that time. Energy-efficient windows cut back on how much cool air is lost through your windows, which makes it easier to keep your house cool.
- Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
Estimated Cost of Window Replacement in Carnot-Moon
Windows come in different purposes, shapes and styles, so costs and services will vary greatly depending on your project. Below, we describe the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.
It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Carnot-Moon homeowners $313+ a year when replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide 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 step when considering a replacement is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you're not sure which kind of window installation service you should get, your installer should be able to advise you. In general, the choice is influenced by 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 Carnot-Moon
In our search to find the most reliable, eco-friendly window installers in Carnot-Moon, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Carnot-Moon area so you can find the best window installation company near you.
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 in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Carnot-Moon's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Carnot-Moon window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Carnot-Moon, PA Window Replacement FAQs
How much does a window install cost?
The typical cost of installing a single window ranges from $450 to $650. There are many factors that influence how much it costs, such as local labor costs, the number of windows, the materials used in designing the windows, your property's location, styles and sizes of windows and how energy-efficient the windows are.
What type of window is the most energy-efficient?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have home repair skills and have all of the necessary tools to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, because rain can make the installation harder.
