How Installing Energy-Efficient Windows in Lennox Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could benefit you:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Lennox, that’s about 117 pounds per year on average.
• 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 fading of your furniture, carpet and other valuables.
• Save on electricity bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $509 annually on your energy bills in Lennox.

Estimated Cost of Window Replacement in Lennox

Each window replacement company provides varying services and has different price points depending on several factors.

How Much Do New Windows Cost?

Though the national average cost of replacing one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, such as type, size, number of windows, the location of your home, material and more.

It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Lennox homeowners $509+ a year when replacing single-pane windows.

Requesting free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

When considering window replacements, in general there are two types that your installer will have: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the total window, including the trim, sill and frame. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Lennox

In our hunt to find the most reliable, eco-friendly window installers in Lennox, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Lennox and assigned rankings using the following methodology:

Service Area

Because this is a guide for Lennox, we gave more points to companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Lennox.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain company, it won’t be 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 hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Lennox’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Lennox window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
