As temperatures rise and days get longer, spring gives homeowners the perfect window of opportunity to take on home improvement projects (pun intended). Windows aren't just about looks—old, drafty windows can drain your energy bills and let in unwanted heat, cold, or moisture.
If you've been putting off the investment (like many of us), now might be the right time to act. With warmer months ahead, it's worth understanding the benefits of upgrading your current windows.
Why Replacing Home Windows Matters More Than You Think
Windows play a much bigger role in your home's comfort and energy use than most people realize. The U.S. Department of Energy says 25% to 30% of residential heating and cooling energy use comes from heat gain and heat loss through windows. And though for most homes windows only cover just 8% of the surface, they account for nearly half of your heat lost or gained, according to EnergyStar.
Poor insulated glass units, aging window seals, or single-pane window designs are all problematic signs of wear. Drafts, foggy panes of glass, and rising energy costs are indications that your windows are working against you. Upgrading them for energy efficiency can bring comfort and savings.
“Certified energy-efficient window attachments offer a cost-effective way to boost comfort, resilience, and cut energy bills. The Department of Energy recommends looking for products with the AERC Energy Improvement rating, which shows performance in both warm and cool climates. Homeowners can visit the AERC website to find the best options for their region,” said Ralph Vasami, Executive Director of the Attachments Energy Rating Council (AERC).
Data backs that up. According to BG&E, certified window attachments can cut electricity costs by 13.5% annually and reduce gas use by 3.4%. That’s more than pocket change, right?
When Should You Replace Windows?
Many homeowners notice problems with their windows during colder weather... drafts around the entire window frame, condensation on the window sashes, high gas and electric bills, the list goes on. You can replace windows any time of the year, but in the interest of keeping your home comfortable, it's best to connect with a window contractor during warmer weather.
"Spring and Summer are the most popular times to replace your existing windows," notes Sam Brubaker, VP of Marketing at Champion Windows, a Great Day Improvements company. "Many people notice their issues during the winter months when heating costs start to rise, or after hurricane and storm seasons pass. That makes replacing your windows a great project to knock out during the milder months, especially since it involves opening up your home during the installation process."
Other common reasons for replacing your windows include:
- Fogging or condensation between double-pane windows (broken seal)
- Drafts or cold spots near window areas (this could be the window, and it could be poor insulation around the window sill and frame)
- Cracked or warped frames
- Noticeable outside noise
- Visible damage or leaks (if not due to damage, attributed to poor installation)
How the Right Products Make All the Difference
If you're thinking about a home window replacement, the type of window you choose matters. Energy-efficient windows and certified window attachments aren’t just for cold climates. They work just as well in warm weather to block heat, reduce glare, and keep rooms cooler.
Remember: Look for products with an AERC label. This label includes a climate rating and performance information based on where you live. Whether you're in a hot, humid region or in an area with cold weather conditions, there's a smart solution. You can even search for products that fit your climate on the AERC website.
Here's what to look for when choosing new windows or attachments:
- ENERGY STAR certified products (we're all in for energy performance)
- Low-E glass to reflect heat
- Double- or triple-pane options for insulation (really, it's time to update any single-pane glass!)
- AERC climate rating for your region
- Automated coverings for added savings and privacy
- Strong warranties and proven durability
Smart shades and coverings over the glass panes also help all window types. They can be programmed to open or close throughout the day for additional long-term savings. Plus, they offer the privacy you expect.
FAQ
Should I replace my windows if I have water damage?
Yes, but also get nearby areas checked. “Water damage can come from many different sources,” says Sam Brubaker. “While it is common to see damage from failed weatherproofing, broken components, or poor window installation, it may be a good idea to ask your contractor to inspect the surrounding areas for possible points of water penetration.” It’s important to fix the root of the problem so new windows don’t suffer the same fate.
How long do modern windows last?
Most new types of windows last 20 to 40 years, depending on materials and installation quality. Vinyl windows and fiberglass windows can last longer than wood frames. Regular maintenance can also help them last longer.
And, while you can DIY a window replacement (I have!), professional installation might be necessary for lifetime warranties. Working with a window replacement company might also help you feel better about preventing water infiltration.
Is replacing home windows worth the cost?
In many cases, yes. While window replacement costs can be a lot to stomach, the return on investment with long-term energy savings and increased comfort usually balances out the material cost. Energy-efficient windows can also raise your home’s value.
