Window Replacement Benefits

Considering replacing those old windows? Here are a few good reasons to do it now.

  • Save money by reducing energy bills
  • Earn federal tax credits up to $500 (where eligible)
  • Can increase the resale value of your home

Why Install Energy Efficient Windows

Upgrading your home’s windows to energy-efficient windows includes a lot of benefits. Benefits of energy-efficient windows:

  • Lower monthly energy bills
  • Less energy waste
  • Better insulation
  • Increased home value
  • Utility company incentives

Saving Money With Energy Efficient Windows 

According to Energy Star, there are some significant financial benefits to replacing single and double-paned windows.

Single-paned Seattle Replacements 

Here in the Pacific Northwest, Energy Star found that we have the second-highest potential for saving money when we replace our single-paned windows. The annual savings of replacing single-paned windows with windows that are Energy Star qualified are about $460. New England can save the most with $465 annual savings. What could you do in Seattle with an extra $460 per year?

Double-paned Seattle Replacement Windows

Of the eleven areas in the picture below, the Pacific Northwest is the second-lowest on annual savings when double-paned windows are replaced. Energy Star found that by replacing double-paned windows with Energy Star qualified windows that we can save $57 per year. Those windows will pay for themselves long before you need Seattle replacement windows again.

Lower HVAC Costs

After your energy-efficient replacement windows have been installed, you’ll notice that your HVAC system doesn’t have to work as hard to heat or cool your house. That’s because the replacement windows reduced the peak loads put on the HVAC system. The peak load is the maximum energy required to heat or cool a home at one time. With a reduced peak load, you don’t need such large HVAC systems – furnace, a/c. A properly sized HVAC system uses much less energy and requires less maintenance, thus saving you money.

If you’re building a home in Seattle, energy-efficient window installation is especially important. That’s because installing the proper HVAC system is easier than replacing one. So if you are looking for windows to install on your new home or homes, or multi-family investment, energy-efficient windows are good for you as well as your tenants.

Comfort In Winter & Summer

Bitter cold temperatures, rain, heat, and moisture from being near the water can make Winters uncomfortable if you don’t have good windows installed in Seattle. The last things you want are drafty windows and doors. 

Did you know that an interior surface temperature of a window lower than 52 degrees Farenheit indicates an uncomfortable temperature inside your home? If you’re near a window and the interior surface is 52 or lower, you’ll likely head for the thermostat to increase the house temperature.

Energy-efficient windows have what is called a “U-factor.” This is a rating of how good or bad heat is transferred through a window. A low U-factor means the window provides good insulation, while a high U-factor means that the window does not provide good insulation or airflow resistance. With an energy-efficient window installed in Seattle, you’ll rarely have to change your thermostat.

In the Summer the situation can be the complete opposite. Sometimes you’re near a window and start sweating because of the sun glaring down on you through the glass. If you experience this, then you probably don’t have an energy-efficient window. Energy Star found that 75% of the Sun’s heat can enter your home through inefficient double-paned windows. Energy Star qualified windows keep you cool because they have a low “heat gain coefficient.” That just means that they prevent solar radiation from being absorbed into your home.

For typical homes, choose ENERGY STAR and save on average*:

$101–$583
and
1,006–6,205 pounds of CO2

which is equivalent to 51 to 317 gallons of gasoline

a year when replacing single-pane windows
$27–$197
and
246–2,001 pounds of CO2

which is equivalent to 13 to 102
gallons of gasoline

a year when replacing double-pane, clear glass windows

* Ranges are based on the average savings among homes in modeled cities. Actual savings will vary based on local climate conditions, utility rates, and individual home characteristics.
