How Installing Energy-Efficient Windows in Harlem Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could help you:

  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • Better temperature control in your home: When you live in a city like Harlem where the winters can be very cold, you often need to depend on your heater to keep your home warm. Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
  • Save money on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.

Estimated Cost of Window Replacement in Harlem

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you'll find from the average window installation company.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But prices differ considerably 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 replacements, which will make your project cost more.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Harlem 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 switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Another factor that affects the overall cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations entail replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. Full-frame installations are more involved and will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Harlem, the decision will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Harlem

In our hunt to make your home improvements easier and more eco-friendly in Harlem, EcoWatch assessed dozens of companies before deciding on these. We have evaluated the best window installation companies in Harlem primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Harlem, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Harlem.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback 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 the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Harlem's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Harlem window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Harlem, OH Window Replacement FAQs

How much should window installation cost?

The national average cost of installing one window is about $600 but can range from $200 to $1,200, based on several factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers will do the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.

Should I replace my windows all at once?

If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
