How Installing Energy-Efficient Windows in Lennox Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:
- Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade 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 damaging UV rays.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save more on your bills.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Lennox
Windows come in varying purposes, styles and shapes, so costs and services will vary tremendously depending on your project. Below, we detail the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in Lennox can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost you is based on several factors, such as type, material, size, number of windows, the location of your home and more.
It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Lennox home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations entail replacing the full window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. Because full-frame installations are more involved, they will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can advise you on the best type for your project. In Lennox, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Lennox
The EcoWatch Reviews team is different from most reviewers, as we're examining these companies through a sustainability lens. We've assessed the top window installers in Lennox primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Lennox, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Lennox.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, professionalism, quality of installation, quality of parts, cost and more.
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
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Lennox, CA Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost to replace a window is around $600 but can range from $200 to $1,200, depending 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 hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are several different kinds of windows you can get for your home, including bay windows, slider windows, casement windows, picture windows, awning windows, transom windows and double-hung and single-hung windows.
What do window installation companies do?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
